Introduction and Specifications

Introduction:

Intel has pushed out many SSDs over the years, and unlike many manufacturers, they have never stopped heavily pushing SSD in the enterprise. They did so with their very first push of the X25-M / X25-E, where they seemingly came out of nowhere and just plunked down a pair of very heavy hitting SSDs. What was also interesting was that back then they seemed to blur the lines by calling their consumer offering 'mainstream', and considering it good enough for even some enterprise applications. Even though the die-hard stuff was left to the SLC-based X25-E, that didn't stop some consumers from placing them into their home systems. The X25-E used in this review came from a good friend of mine, who previously had it installed in his home PC.

With several enterprise class models out there, we figured it was high time we put them all alongside each other to see where things are at, and that's the goal of this particular piece. We were motivated to group them together by the recent releases of the DC S3500 and DC S3700 drives, both using Intel's new Intel 8-channel controller.

Specifications:

  X25-E SSD 320 SSD 710 SSD 910* DC S3500 DC S3700
Capacity 32, 64GB 40, 80, 120, 160, 300, 600GB 100, 200, 300GB 400, 800GB 80, 120, 160, 240, 300, 480, 600, 800GB 100, 200, 400, 800GB
Read (seq) 250 270 270 500 500 500
Write (seq) 170 205 210 375 410 365
Read (4k) 35k 39.5k 38.5k 45k 75k 75k
Write (4k) 3.3k 23k (8GB span) 2.7k 18.7k 11k 32k
  • Since the SSD 910 is subdivided into 4 or 2 (depending on capacity) physical 200GB volumes, we chose to test just one of those physical units. Scaling can then be compared to other units placed into various RAID configurations. 910 specs were corrected to that of the single physical unit tested.
  • All other listed specs are specific to the tested (bold) capacity point.

 

 

Controllers:

Starting with the good old X25-E, which pretty much started it all, is Intel's original SATA 3Gb/sec 10-channel controller. Despite minor tweaks, this same controller was used in the X25-M, X25-M G2, SSD 320 and SSD 710 Series. Prior to Intel releasing their own 6Gb/sec SATA controller, they filled some of those voids by introducing Marvell and SandForce controllers with the 510 and 520, respectively, but those two were consumer-oriented drives. For the enterprise, Intel filled this same gap with the 910 Series - a PCIe LSI Falcon SAS RAID controller driving 2 or 4 6Gb/sec SAS Hitachi Ultrastar SSDs. Finally (and most recently), Intel introduced their own SATA 6Gb/sec controller in the form of the DC S3500 and DC S3700. Both are essentially the same 8-channel controller driving 20nm or 25nm IMFT flash, respectively.

More to follow on the next page, where we dive into the guts of each unit.

Introduction

Last month OCZ introduced the Vertex 3.20, which took their popular Vertex line to 20nm flash territory. The Vertex 3.20 used the same tride and true SandForce controller used in previous iterations of that line. The older Vertex line was starting to show its age, and the move to 20nm didn't really help the issue. We knew it was just a matter of time before they brought 20nm to their Indilinx Barefoot line, and that time is now. The new model suggests OCZ may abandon the Vector name, and resurrect the performance of their flagship product line by shifting their Indilinx Barefoot 3 (BF3-M10) over to a newly dubbed Vertex 450:

Introduction

Introduction

Seagate recently announced and released their third generation of laptop Solid State Hybrid Drives. Originally thier hybrids carried the Momentus (laptop HDD) name forward, tacking on 'XT' to denote the on-board caching ability. The Momentus XT was intriduced in a 500GB (1st gen) and 750GB (2nd gen) model. The new line gets a new and simple title - Laptop SSHD.

laptop-sshd-family-gallery-500x500.jpg

In addition to the new name, we now have two capacity points available. The 'Laptop SSHD' retains the old 9.5mm form factor and now pushes a full 1TB of capacity, while the 'Laptop Thin SSHD' drops a platter and reduces availabile capacity to 500GB. The bonus with the 500GB model is that it maintains similar performance yet shaves off some thickness, making it Seagate's first 7mm Hybrid.

Today we will take a look at the new Thin SSHD, comparing it to the performance of the older generation Seagate Hybrids, as well as to Intel's RST caching solution:

Introduction

A while back, we saw OCZ undergo a major restructuring. 150+ product SKUs were removed from their lineup, leaving a solid core group of products for the company to focus on. The Vertex and Agility lines were spared, and the Vector was introduced and well received by the community. With all of that product trimming, we were bound to see another release at some point:

ext-front.JPG

Today we see a branch from one of those tree limbs in the form of the Vertex 3.20. This is basically a Vertex 3, but with the 25nm IMFT Sync flash replaced by newer 20nm IMFT Sync flash. The drop to 20nm comes with a slight penalty in write endurance (3000 cycles, down from the 5000 rating of 25nm) for the gain of cheaper production cost (more dies per 300mm wafer).

imft 20 nm.jpg

IMFT has been cooking up 20nm flash for a while now, and it is becoming mature enough to enter the mainstream. The first entrant was Intel's own 335 Series, which debuted late last year. 20nm flash has no real groundbreaking improvements other than the reduced size, so the hope is that this shrink will translate to lower cost/GB to the end user. Let's see how the new Vertex shakes out.

Specifications:

  • Capacity: 120, 240GB
  • Sequential read:  550 MB/sec
  • Sequential write: 520 MB/sec
  • Random read IOPS (up to):  35 k-IOPS
  • Random write IOPS (up to):  65 k-IOPS

Oyen Digital, a popular manufacturer of portable storage enclosures and devices, provided us with its MiniPro™ eSATA / USB 3.0 Portable Hard Drive enclosure for testing USB 3.0 enhanced mode on the ASUS P8Z77-I Deluxe motherboard. This enclosure offers support for USB 2.0, USB 3.0, and eSATA ports in conjunction with a 2.5" hard drive. We put this enclosure on the test bench with the ASUS P8Z77-I Deluxe board to test the performance limits of the device. The MiniPro™ enclosure can be found at your favorite e-tailer for $39.95.

The MiniPro™ SATA / USB 3.0 Portable Hard Drive enclosure is a simple aluminum enclosure supporting any 2.5" form factor hard drive up to SATA III speeds. The enclosure itself supports USB 2.0, USB 3.0, and eSATA connections. Because of its use of the ASMedia 1053e chipset for USB 3.0 support, the enclosure supports both USB 3.0 normal mode transfer speeds and UASP (USB Attached SCSI Protocol) mode transfer speeds. UASP mode is a method of bulk transfer for USB 3.0 connections that increases transfer speeds through the use of parallel simultaneous packet transfers. Per our sources at ASUS, UASP can be explained as follows:

The adoption of the SCSI Protocol in USB 3.0 provides its users with the advantage of having better data throughput than traditional BOT (Bulk-Only Transfer) protocol, all thanks to its streaming architecture as well as the improved queuing (NCQ support) and task management, which eliminated much of the round trip time between USB commands, so more commands can be sent simultaneously. Moreover, thanks to the multi-tasking aware architecture, the performance is further enhanced when multiple transfers occur.
The downside of UASP is that the receiving device (Flash drive/external hard drive etc) must also be UASP enabled for the protocol to work. This requires checking your peripherals before purchase. However since UASP is an industry standard, the device support for ASUS UASP implementation is not restricted to a particular controller manufacturer or device type, so the overall number of peripherals available should undoubtedly grow.

Introduction, Specifications, and Packaging

Last year we did a combined review of the ioSafe SoloPRO and the Synology Diskstation 212+ NAS solution. The ioSafe handled the function of disaster-hardened storage, capable of withstanding a typical building fire along with the resulting drenching from your friendly neighborhood fire department, while the DiskStation made the USB-connected ioSafe available to the network and added numerous additional features as part of its excellent DSM software suite, offering many features to both both home and business users:

The whole time I was working on that article, I kept wondering how cool it would be if both items were combined into one unit. You could then get the additional benefit of multi-drive redundancy *and* the disaster-proof protection offered by the ioSafe. Well, that just happened:

Taking an Accurate Look at SSD Write Endurance

Last year, I posted a rebuttal to a paper describing the future of flash memory as ‘bleak’. The paper went through great (and convoluted) lengths to paint a tragic picture of flash memory endurance moving forward. Yesterday a newer paper hit Slashdotthis one doing just the opposite, and going as far as to assume production flash memory handling up to 1 Million erase cycles. You’d think that since I’m constantly pushing flash memory as a viable, reliable, and super-fast successor to Hard Disks (aka 'Spinning Rust'), that I’d just sit back on this one and let it fly. After all, it helps make my argument! Well, I can’t, because if there are errors published on a topic so important to me, it’s in the interest of journalistic integrity that I must now post an equal and opposite rebuttal to this one – even if it works against my case.

First I’m going to invite you to read through the paper in question. After doing so, I’m now going to pick it apart. Unfortunately I’m crunched for time today, so I’m going to reduce my dissertation into the form of some simple bulleted points:

  • Max data write speed did not take into account 8/10 encoding, meaning 6Gb/sec = 600MB/sec, not 750MB/sec.
  • The flash *page* size (8KB) and block sizes (2MB) chosen more closely resemble that of MLC parts (not SLC – see below for why this is important).
  • The paper makes no reference to Write Amplification.

Perhaps the most glaring and significant is that all of the formulas, while correct, fail to consider the most important factor when dealing with flash memory writes – Write Amplification.

Before geting into it, I'll reference the excellent graphic that Anand put in his SSD Relapse piece:

writeamplification2.png

SSD controllers combine smaller writes into larger ones in an attempt to speed up the effective write speed. This falls flat once all flash blocks have been written to at least once. From that point forward, the SSD must play musical chairs with the data on each and every small write. In a bad case, a single 4KB write turns into a 2MB write. For that example, Write Amplification would be a factor of 500, meaning the flash memory is cycled at 500x the rate calculated in the paper. Sure that’s an extreme example, but the point is that without referencing amplification at all, it is assumed to be a factor of 1, which would only be the case if you were only writing 2MB blocks of data to the SSD. This is almost never the case, regardless of Operating System.

After posters on Slashdot called out the author on his assumptions of rated P/E cycles, he went back and added two links to justify his figures. The problem is that the first links to a 2005 data sheet for 90nm SLC flash. Samsung’s 90nm flash was 1Gb per die (128MB). The packages were available with up to 4 dies each, and scaling up to a typical 16-chip SSD, that only gives you an 8GB SSD. Not very practical. That’s not to say 100k is an inaccurate figure for SLC endurance. It’s just a really bad reference to use is all. Here's a better one from the Flash Memory Summit a couple of years back:

flash-1.png

The second link was a 2008 PR blast from Micron, based on their proposed pushing of the 34nm process to its limits. “One Million Write Cycles” was nothing more than a tag line for an achievement accomplished in a lab under ideal conditions. That figure was never reached in anything you could actually buy in a SATA SSD. A better reference would be from that same presentation at the Summit:

flash-2.png

This shows larger process nodes hitting even beyond 1 million cycles (given sufficient additional error bits used for error correction), but remember it has to be something that is available and in a usable capacity to be practical for real world use, and that’s just not the case for the flash in the above chart.

At the end of the day, manufacturers must balance cost, capacity, and longevity. This forces a push towards smaller processes (for more capacity per cost), with the limit being how much endurance they are willing to give up in the process. In the end they choose based on what the customer needs. Enterprise use leans towards SLC or eMLC, as they are willing to spend more for the gain in endurance. Typical PC users get standard MLC and now even TLC, which are *good enough* for that application. It's worth noting that most SSD failures are not due to burning out all of the available flash P/E cycles. The vast majority are due to infant mortality failures of the controller or even due to buggy firmware. I've never written enough to any single consumer SSD (in normal operation) to wear out all of the flash. The closest I've come to a flash-related failure was when I had an ioDrive fail during testing by excessive heat causing a solder pad to lift on one of the flash chips.

All of this said, I’d love to see a revisit to the author’s well-structured paper – only based on the corrected assumptions I’ve outlined above. *That* is the type of paper I would reference when attempting to make *accurate* arguments for SSD endurance.

Introduction

With newer and faster SSDs coming to market, we should not forget those capable controllers of yesteryear. There are plenty of folks out there cranking out products based on controllers that were until very recently the king of the hill. Competition is great for the market, and newer product launches have driven down the cost of the older SandForce 2281 SATA 6Gb/sec controller. ADATA makes a product based on this controller, and it's high time we gave it a look:

130205-221436-4.13.jpg

The ADATA XPG SX900 launched mid last year, and was ADATA's first crack at the eXtended capacity variant of the SandForce firmware. This traded off some of the spare area in the interest of more capacity for the consumer.

Introduction

It has been just under a year since Intel released their 520 Series SSD, which was their second 6 Gb/sec SATA unit. Sporting a SandForce controller, that release helped bridge a high speed storage gap in their product lineup. One year prior, Intel dabbled in the mSATA form factor, releasing a 310 Series model under that moniker. The 310 showed up here and there, but never really caught on as the physical interface was admittedly before its time. While in hindsight it was a very good way to go towards establishing a fixed standard, the industry had already begun fragmenting on these smaller interfaces. The MacBook Air had already launched with a longer 'GumStick' shaped SSD, and Ultrabook makers were following suit with units that were physically identical yet not pin-compatible with that used in the Apple product.

intel520.jpg

The Intel 520 Series SSD helped push Intel into 6Gb/sec SATA territory.

It's taken a while for the industry to favor defragmentation (pun intended) enough for mSATA to really start catching on, and that time appears to be nearing with Intel's launch of the SSD 525 Series:

Introduction

OCZ has been in the SSD game for quite some time, and has previously done quite well mixing and matching hardware from other vendors into solutions of their own. It was a good way to put out a large array of products, fitting many a niche for a decent cost. Further, OCZ has always been known as somewhat of an underdog who tailored their parts more towards the power user / tweaker crowd. All of that said, they have been taking steps to become more of a major player in the SSD market, and the fruits of that labor begin their payoff today, with the release of the OCZ Vector:

A new Indilinx Controller?

The Vector comes equipped with a bunch of firsts for OCZ. The controller is OCZ's first 100% in-house part, and has been engineered from the ground up to be as high of a performing part as possible. There has been a paradigm shift within OCZ lately, and the Vector went through a large beta test phase *before* release, as to avoid the need for a series of rapid fire firmware updates just after the product ships. Vector should perform at or near its maximum potential today, not after some firmware updates seen months from now. Here's a look at the controller functional block diagram:

Introduction

It's been a short while since we've seen a consumer SSD release from Intel, and with pressure coming from Samsung in the form of lower cost/GB 20nm flash, it was high time Intel followed suit. The Intel 335 Series launches today, and is essentially the same SandForce-driven product as their SSD 520 Series released earlier this year. The key change is this time around that controller will be driving Intel 20nm flash. This should bring a much needed price reduction to the SSD arena, as the 335 is not being marketed as a 'Pro' unit (like the Samsung's 840 Pro). So long as this new model performs similarly to the 520 Series, we should be in for a good, low cost SSD just in time for the Christmass shopping season.

Wireless storage for PC, Mac, iOS and Android

Today we are taking a look at the new Patriot Gauntlet 320 external USB 3.0 and wireless hard drive, available starting at $149 at Newegg.com.

Gauntlet_320_Pkg_Left.jpg

The premise is quite simple: take a portable hard drive with USB 3.0 support and add in the ability to share the unit wirelessly with up to 8 different machines and power it by a lithium-ion battery.  Not only does the Gauntlet show up in your network as a mountable drive in Windows and Mac OS, the Gauntlet supports using free applications for iOS devices and Android devices to share and stream media.

Gauntlet_320-Left.png

There are some limitations that you might want to consider including the inability to access network-based devices when using the pass through Internet capability the Gauntlet provides.  Also, data transfer performance on the wireless connectivity that the Gauntlet provides seemed pretty low, even with the 802.11n support. 

Potential uses cases for the Gauntlet include any time you need a shared data source like working on group projects for school or the office, on-the-go storage for devices like Ultrabooks with smaller hard drives and users that have large media collections they want to use with smart phones and tablets.

Check out our full video review below!

Note that in the video, our early sample of the Gauntlet 320 has the "node" label on it; the Gauntlet Node is a separate device that is only a DIY enclosure WITHOUT an included hard drive.  Originally there was a sticker cover the "node" label but incorrectly removed it before filming.  Just a heads up!

Introduction:

The Western Digital RAID Edition line of hard drives has been around for some time now, and has largely impressed us with each subsequent release. Since the launches of the RE4-GP and later, the faster spinning RE4, WD's enterprise line had been capped at the 2TB mark. Now that has changed with the introduction of a new line: simply named the RE Series:

Yup, that's right. 4 TeraBytes! With the Green and Red series capped at 3TB, this new RE is the largest capacity drive available from Western Digital. The catch is that, since it's tailored and built for enterprise use, it comes at a rather hefty price premium.

Last week, Samsung flew myself and a few of my fellow peers in the storage review community out to Seoul, Korea. The event was the 2012 Samsung SSD Global Summit:

120924-104020-4.28.jpg

At this event, Samsung officially announced their new 840 Pro, which we were able to obtain early under NDA and therefore publish in concert with the announcement. The 840 Pro was largely an incremental inprovement over their 830 Series. Newer, faster flash coupled with a higher clocked controller did well to improve on an already excellent product.

121002-220858-6.35.jpg

As the event closed, we were presented with the second model of the lineup - the 840. This model, sans the 'Pro' moniker, is meant more for general consumer usage. The first mass marketed SSD to use Triple Level Cell (TLC) flash, it sacrifices some write speed and long-term reliability in favor of what should become considerably lower cost/GB as production ramps up to full capacity. TLC flash is the next step beyond MLC, which is in turn a step after SLC. Here's a graphic to demonstrate:

Introduction

Samsung has been at this SSD thing for quite some time now. The first SSD I bought was in fact a Samsung unit meant for an ultraportable laptop. Getting it into my desktop was a hack and a half, involving a ZIF to IDE adapter, which then passed through yet another adapter to convert to SATA. The drive was wicked fast at the time, and while it handily slaughtered my RAID-0 pair of 74GB VelociRaptors in random reads, any writes caused serious stuttering of the drive, and therefore the entire OS. I was clearly using the drive outside of its intended use, but hey, I was an early adopter.

Several SSDs later came the Intel X25-M. It was a great drive, but in its earliest form was not without fault. Luckily, these kinks were worked out industry-wide, and everyone quickly accelerated their firmware optimizations as to better handle random writes. Samsung took a few generations to get this under control. The first to truly get over this hump was the 830 Series, which launched earlier this year. It utilized a triple core Arm 9 CPU which was able to effectively brute force heavy random write workloads. It also significantly increased the speed and nimbleness of the 830 across the board, which combined with Samsung's excellent reliability record, quickly made it my most recommended series as of late.

DSC00687.JPG

...and now we have the 840 Series, which launched today. Well, technically it launched yesterday if you're reading from the USA. Here in Korea the launch started at 10 AM and spanned a day of product press briefings leading to the product NDA expiration at 8 PM Korea time. This review will focus on the 512GB capacity of the 840 Pro model. We will follow on with the 840 (non-pro) at a later date:

Introduction:

I'm going to let the cat out of the bag right here and now. Everyone's home RAID is likely an accident waiting to happen. If you're using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I'm guilty of operating under this same false hope - I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails. The RAID controller can simply figure out the missing data by running the extra parity through the same formula that created it. This is called redundancy, but I propose that it's not.

An overview of Thunderbolt Technology

The promise of Thunderbolt connectivity has been around for a couple of years now. Today, Thunderbolt is finally finding its way to the PC platform in the form of motherboards from ASUS and MSI. First unveiled as "Light Peak" at the Intel Developer Forum in 2009, the technology started out as a way to connect multiple devices to a system over a fiber optic cable (hence the 'light' in the name), though the final products have changed the implementation slightly.

lightpeak-2.JPG

The first prototype implementations actually used a USB-style connection and interface. It further required fiber optic cables. When it was renamed to Thunderbolt and then released in conjunction with a new lineup of Apple MacBook laptops, not only did the physical interface move to a mini-DisplayPort connection but the cable was made to use copper rather than fiber. Without diving too far into the reasons and benefits of either direction, the fact is that the copper cables allow for modest power transfer and are much cheaper than fiber optic variants would be.

slide01.jpg

Thunderbolt's base technology remains the same, however. It is a transfer standard that allows for 10 Gbps of bandwidth for each channel (bi-directional) and concurrently supports both data and display connections. The actual interface for the data path is based on PCI Express and connected devices actually appear to Windows as if they are internally connected to the system which can offer some interesting benefits – and headaches – for hardware developers. The display connection uses the DisplayPort standard and can be used along with the data connection without affecting bandwidth levels or performance.  

slide02.jpg

For current Intel processor implementations, the Thunderbolt connection is supported by a separate controller chip on the motherboard (or a riser card) – and some routing is required for correct usage. The Thunderbolt controller does not actually include a graphics controller, so it must be fed an output from another graphics processor, obviously in this case directly from the Ivy Bridge / Sandy Bridge processors. In theory, these could be from other controllers, but with the ubiquitous nature of integrated processor graphics on IVB and SNB processors, this is going to be the implementation going forward according to motherboard and system designers.

ioSafe: Introduction and Internals

Introduction:

Cloud storage is all the talk these days, and our own Tim Verry has been hard at work detailing as much of it as he can keep up with. While all of us at PCPer currently use cloud based solutions for many of the day-to-day goings on, it's not for everyone, and it tends to not be for very large chunks of data, either. Sometimes local storage is just the way to go – especially when you want to be the one in absolute control of the reliability and integrity of your data.

The general rule for proper backups is to have your local copy, a local backup (RAID is *not* a backup), and an additional off-site backup to cover things like theft, fires or floods. So lets say you simply have too much sensitive data for your internet connection to support bulk transferring to an off-side / cloud storage location. Perhaps the cloud storage for that much space is simply cost prohibitive, or your data is sensitive enough that – despite encryption – you don't want it leaving your network and/or premesis? Perhaps you're just stubborn and want only one backup of your data? I think I might have the answer you've been looking for – behold the ioSafe SoloPRO:

120205-095626-8.39.jpg

What is this thing, you may ask? On the inside it's one of the available 1, 2, 3, or even 4TB 3.5" hard drives. On the outside it's a very durable and solid steel enclosure. The hard drive is wrapped in a thermally conductive yet water resistant 'HydroSafe' foil that enables water resistance rated at a 10 ft depth for 3 days with no data loss. The bonus, however, is not the water resistance - that featuer is present primarily to battle the side effects of something much more drastic - the ioSafe is fire-proof. That feature comes from what sits between the steel casing and the shrink wrapped hard drive - something ioSafe calls a DataCast (pictured below):

I'm going to break from my normal warranty voiding and show a photo from this past Storage Visions conference at the Consumer Electonics Show, where an ioSafe was already cracked open for our viewing pleasure:

Inside and Out

When you are a little fish in the great big pond of PC builders, you need to do something to stand out from the rest.  The people behind DV Nation apparently were well aware of that when entering the system vendor business and offering up SSDs to every single system configuration.  Through a new system they are offering, provocatively named the "RAMRod PC", DV Nation provides a pre-built system that has some very unique components and configuration settings.

Built around the Antec Three Hundred Two chassis, the first glance at the RAMRod doesn't really indicate anything special is going on under the hood.  But let's take a quick look at the specs:

  • Intel Core i7-3820 @ 4.4 GHz
  • 64GB DDR3-1600 Memory from G.Skill
  • Radeon HD 6990 4GB 
  • 2x Seagate Momentus XT 750GB Hybrid HDD in RAID-0
  • OCZ RevoDrive 3 X2 480GB PCIE SSD
  • RAMCache: SuperSpeed Supercache 8GB on PCIE SSD, 8GB on Momentus
  • RAMDisk: 42GB ROMEX Primo rated at 8000 MB/s
  • Cost: $5,400

Obviously there is a LOT of storage work going on in the RAMRod and the purpose of the rig is to be the fastest pre-configured storage available anywhere.  If you are looking for a cheaper version of this system you can get a base model with 16GB of memory, 10GB RAMDisk, 2GB RAMCache, 240GB PCIe SSD, single standard hard drive and even at GTX 680 for $2999.

Let's take a quick walk around the rest of the system before diving into the benchmarks!
