Introduction

** Edit **

The tool is now available for download from Samsung here. Another note is that they intend to release an ISO / DOS version of the tool at the end of the month (for Lunix and Mac users). We assume this would be a file system agnostic version of the tool, which would either update all flash or wipe the drive. We suspect it would be the former.

** End edit **

As some of you may have been tracking, there was an issue with Samsung 840 EVO SSDs where ‘stale’ data (data which had not been touched for some period of time after writing it) saw slower read speeds as time since written extended beyond a period of weeks or months. The rough effect was that the read speed of old data would begin to slow roughly one month after written, and after a few more months would eventually reach a speed of ~50-100 MB/sec, varying slightly with room temperature. Speeds would plateau at this low figure, and more importantly, even at this slow speed, no users reported lost data while this effect was taking place.

900x900px-LL-4985de76_2014-09-1720.18.26TestresultsforC_0.png

An example of file read speeds slowing relative to file age.

Since we first published on this, we have been coordinating with Samsung to learn the root causes of this issue, how they will be fixed, and we have most recently been testing a pre-release version of the fix for this issue. First let's look at the newest statement from Samsung:

Because of an error in the flash management software algorithm in the 840 EVO, a drop in performance occurs on data stored for a long period of time AND has been written only once. SSDs usually calibrate changes in the statuses of cells over time via the flash management software algorithm. Due to the error in the software algorithm, the 840 EVO performed read-retry processes aggressively, resulting in a drop in overall read performance. This only occurs if the data was kept in its initial cell without changing, and there are no symptoms of reduced read performance if the data was subsequently migrated from those cells or overwritten. In other words, as the SSD is used more and more over time, the performance decrease disappears naturally.  For those who want to solve the issue quickly, this software restores the read performance by rewriting the old data. The time taken to complete the procedure depends on the amount of data stored.

This partially confirms my initial theory in that the slow down was related to cell voltage drift over time. Here's what that looks like:

threshold shift.png

As you can see above, cell voltages will shift to the left over time. The above example is for MLC. TLC in the EVO will have not 4 but 8 divisions, meaning even smaller voltage shifts might cause the apparent flipping of bits when a read is attempted. An important point here is that all flash does this - the key is to correct for it, and that correction is what was not happening with the EVO. The correction is quite simple really. If the controller sees errors during reading, it follows a procedure that in part adapts to and adjusts for cell drift by adjusting the voltage thresholds for how the bits are interpreted. With the thresholds adapted properly, the SSD can then read at full speed and without the need for error correction. This process was broken in the EVO, and that adaptation was not taking place, forcing the controller to perform error correction on *all* data once those voltages had drifted near their default thresholds. This slowed the read speed tremendously. Below is a worst case example:

840 EVO 512 test hdtach-2-.png

We are happy to say that there is a fix, and while it won't be public until some time tomorrow now, we have been green lighted by Samsung to publish our findings.

Introduction and Test System Setup

A while ago, in our review of the WD Red 6TB HDD, we noted an issue with the performance of queued commands. This could potentially impact the performance of those drives in multithreaded usage scenarios. While Western Digital acted quickly to get updated drives into the supply chain, some of the first orders might have been shipped unpatched drives. To be clear, an unpatched 5TB or 6TB Red still performs well, just not as well as it *could* perform with the corrected firmware installed.

DSC05778.JPG

We received updated samples from WD, as well as applying a firmware update to the samples used in our original review. We were able to confirm that the update does in fact work, and brings a WD60EFRX-68MYMN0 to the identical and improved performance characteristics of a WD60EFRX-68MYMN1 (note the last digit). In this article we will briefly clarify those performance differences, now that we have data more consistent with the vast majority of 5 and 6TB Reds that are out in the wild.

Test System Setup

We currently employ a pair of testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and an ASUS Z87-PRO. Storage performance variance between both boards has been deemed negligible.

Introduction and Specifications

Today Micron lifted the review embargo on their new M600 SSD lineup. We covered their press launch a couple of weeks ago, but as a recap, the headline new feature is the new Dynamic Write Acceleration feature. As this is a new (and untested) feature that completely changes the way an SSD must be tested, we will be diving deep on this one later in this article. For the moment, let's dispose with the formalities.

Here are the samples we received for testing:

DSC05770.JPG

It's worth noting that since all M600 models use 16nm 128Gbit dies, packaging is expected to have a negligible impact on performance. This means the 256GB MSATA sample should perform equally to its 2.5" SATA counterpart. The same goes for comparisons against M.2 form factor units. More detail is present in the specs below:

Specifications:

M600-4.png

Highlights from the above specs are the increased write speeds (no doubt thanks to Dynamic Write Acceleration) and improved endurance figures. For reference, the prior gen Micron models were rated at 72TB (mostly regardless of capacity), so seeing figures upwards of 400TB indicates Micron's confidence in their 16nm process.

Packaging:

Sorry to disappoint here, but the M600 is an OEM targeted drive, meaning its 'packaging' will likely be the computer it comes installed in. If you manage to find it through a reseller, it will likely come in OEM-style brown/white box packaging.

We have been evaluating these samples for just under a week and have logged *many* hours on them, so let's get to it!

** End edit 3 **

Over the past week or two, there have been growing rumblings from owners of Samsung 840 and 840 EVO SSDs. A few reports scattered across internet forums gradually snowballed into lengthy threads as more and more people took a longer look at their own TLC-based Samsung SSD's performance. I've spent the past week following these threads, and the past few days evaluating this issue on the 840 and 840 EVO samples we have here at PC Perspective. This post is meant to inform you of our current 'best guess' as to just what is happening with these drives, and just what you should do about it.

The issue at hand is an apparent slow down in the reading of 'stale' data on TLC-based Samsung SSDs. Allow me to demonstrate:

840 EVO 512 test hdtach-2-.png

You might have seen what looks like similar issues before, but after much research and testing, I can say with some confidence that this is a completely different and unique issue. The old X25-M bug was the result of random writes to the drive over time, but the above result is from a drive that only ever saw a single large file write to a clean drive. The above drive was the very same 500GB 840 EVO sample used in our prior review. It did just fine in that review, and at afterwards I needed a quick temporary place to put a HDD image file and just happened to grab that EVO. The file was written to the drive in December of 2013, and if it wasn't already apparent from the above HDTach pass, it was 442GB in size. This brings on some questions:

  • If random writes (i.e. flash fragmentation) are not causing the slow down, then what is?
  • How long does it take for this slow down to manifest after a file is written?

It seems a lot of folks have been incorporating Silicon Motion's SM2246EN controller into their product lines. We first reviewed the Angelbird SSD wrk, but only in a 512GB capacity. We then reviewed a pair of Corsair Force LX's (256GB and 512GB). ADATA has joined the club with their new Premier SP610 product line, and today we are going to take a look at all available capacities of this new model:

Today I'm going to talk to you about something you might not have thought you needed, but once you realize what this new device can do, you might just want one. Imagine a Western Digital My Cloud, but only smaller, battery powered, and wireless. You could fill it with a bunch of movies, music, and other media for something like an upcoming family road trip. If said device could create its own wireless hotspot, the kids could connect to it via their tablets or other portable devices and watch their movie of choice during the drive. Once you are at your destination and snapping a bunch of photos, it would also be handy if this imaginary device could also mount SD cards for sharing recently taken photos with others on your trip. A bonus might be the ability to store a back-up of those SD cards as they become full, or maybe even empty them for folks without a lot of SD capacity available. As a final bonus, make all of this work in such a way that you could pull off an entire trip with *only* mobile devices and tablets - *without* a PC or a Mac. Think all of that can happen? It can now!:

Introduction:

AMD has been branching their brand out past CPUs for nearly a decade now. Back in 2006, AMD acquired ATI, and their video card branch has been highly competitive ever since. Then in 2011, AMD entered the RAM market by partnering with Patriot and VisionTek. That partnership appears to have been fruitful, along with some additional help in the form of RAMDisk software through an additional partnership with Dataram, as more recently a highly competitive Gamer Series of that RAM was launched. So, CPU's - check, GPU's - check, RAM - check. What's next? Solid State Drives? Sure, why not!

Behold the AMD Radeon R7 SSD!

Ok, so the naming might be a bit confusing for those familiar with AMD's video card line of the same name, so you'll have to be sure to include 'SSD' in your searches if you are looking for one of these on the market. Just like AMD handled the RAM, they have again chosen to partner with another company in the creation of a new product:

lineup.png

...and this time that choice was OCZ. As you can see above, the Radeon R7 is a gamer-oriented SSD, which sits right in between the Vertex 460 and the Vector 150 in OCZ's product lineup. The expectation is performance similar to the Vector, but with a slightly lower warranty and GB/day rating. We also see the inclusion of the lower cost 'advanced' Toshiba A19nm MLC flash, which should help with pricing and get this new SSD into the hands of even more gamers.

Introduction:

You might have never heard of Angelbird - until now, that is. Angelbird Technologies GmbH is an SSD maker based out of Vorarlberg, Austria. Their product lines have historically focused around high end and Mac-based products, with a recent arch into portable SSDs (like their SSD2go line). Angelbird is known for their high build quality, and their products are assembled using a technique I can appreciate - vapor phase soldering - (seen here) a technique that puts the least possible thermal stress on the components, as well as ensuring all solder joints are oxygen free. While the vast majority of the their prior products have been build around SandForce controllers, today they have launched a new line, the SSD wrk:

DSC04601.JPG

The Angelbird SSD wrk is built around a new (to them) controller, the SM2246EN from Silicon Motion:

Silicon Motion prides themselves on making SSD controllers that deliver good performance at very low power consumption. For those wanting more detail on this particular controller technology, we have a detailed analysis from last August, available at this page.

Introduction:

OCZ is on what I would consider to be an upswing now that it exists under the relative safety of its parent company, Toshiba. Shortly after they were acquired, OCZ cut a bunch of unnecessary and/or redundant SKUs from their inventory and simultaneously began the transition of all of their product lines to exclusively use Toshiba branded flash. It only makes sense, given that flash is now available in-house - a luxury OCZ had wanted to have for quite some time. The changeover so far has refreshed the Vector 150, Vertex 460, and most recently the RevoDrive 350. Today OCZ has made another change, but instead of refreshing an old product, they are introducing a new one:

DSC04573.JPG

Behold the ARC 100!

To those wondering why OCZ needs another model SSD, and where that model will fall in their lineup, here's everything you need to see:

comparison.png

...so we have a slightly de-rated SSD, with the same Indilinx Barefoot controller, and the same Toshiba 19nm flash, but with a *significantly* reduced price. I wouldn't sweat the 20GB/day rating, as the vast majority of users will average far less than that daily when that usage is spread over a multi-year period. Even heavy gamers that blow through 100+GB of writes on an initial system and game install will still average far less than that over the subsequent months and years. Here is a look at the complete OCZ product spectrum, including their business and PCIe offerings:

spectrum.png

In our prior (and this) review, we've covered the whole bottom row. While we have reviewed the Z-Drive 4500 / XL's predecessor (the Z-Drive R4), The 4500 is not yet on finalized firmware. 

OK, so they've got my attention with this price thing, so lets see how well the ARC performs given its lower cost:

The Thecus N2560 is a dual-bay NAS Server powered by an Intel Atom SoC. With the addition of HDMI output could this be the answer for some basic HTPC needs as well?

N2560_HDMI.JPG

The Thecus N2560 at work in the living room

The N2560 is similar in some ways to the Thecus N2310 NAS we looked at a couple of months ago, but it builds on both the functionality and power of that unit. Both are 2-bay designs with support for up to 8TB of storage via dual 4TB hard drives, and they run the same OS (ThecusOS 6). There are some very big differences, too. The N2560 boasts an Intel Atom SoC which provides dual 1.60 GHz cores, compared to the N2310’s single 800 MHz PowerPC core. The N2560 also features a full-size HDMI output as well as SPDIF digital audio output, making it a potential alternative for some HTPC tasks.

The Thecus N2560 is an attractive-looking device, with the smooth lines and finish of a more expensive product. But beyond the N2560's appearance and basic function as a NAS, this is really a server. Digital audio and video output is certainly an impressive addition for a device that retails for around $180, making it a compelling budget HTPC option if the OS and media software work well. Since the basics of the Thecus OS and NAS usage were covered with the N2310, the media output potential of the N2560 is the area of focus for this review.

A few months back, we took a look at the ADATA Premier Pro SP920 series of SSDs. Those came equipped with the Marvell 88SS9189 controller. Marvell SSD controllers have always done a good job, and they were among the first to support SATA 6Gbit speeds. Crucial was one of the first to adopt the Marvell controller into their SATA SSD products, so it seems fitting that we revisit the 88SS9189 controller in the form of Micron's Crucial M550 Series of SSDs:

*** NOTE ***

In the preparation for this review, we noted abnormal behavior with the 6TB Red. After coordination with Western Digital, they replicated our results and will be issuing a firmware to correct the issue. We are publishing this piece as-is, with caveats added as appropriate. We will revisit this piece with an additional update once we have retested the 6TB Red on the updated firmware / configuration. More information / detail is available in our related news post on this matter.

*** END NOTE ***

Last year we covered the benefits of TLER enabled drives, and the potential for drive errors in a RAID can lead to the potential loss of entire arrays. Western Digital solved this problem by their introduction of the WD Red series. That series was since incrementally updated to include a 4TB capacity, and other Western Digital lines were also scaled up to 4TB capacities.

20140715-195152.jpg

This week the Red line was updated to include both 5TB and 6TB models, sporting 1.2TB per platter. Performance is expected to be slightly improved over the older / smaller capacities of the Red. The upgraded line will use an improved 'NASware 3.0' firmware, which makes improvements to Western Digital's software based vibration compensation. These improvements mean WD can now support up to 8 Reds in a single chassis (up from 5 with NASware 2.0).

Also announced was the new Red Pro line, available in capacities up to 4TB. The Red Pro is just as it sounds - a 'Pro' version of the Red. This model borrows more features from WD's enterprise line, making it very similar to an SE series HDD. Imagine a Red, but at 7200RPM and more aggressive seek times. The Red Pro also borrows the enterprise-grade 5-year warranty and is supported in chassis up to 16 bays, thanks to built-in hardware vibration compensation. When all is said and done, the Red Pro is basically a WD SE with firmware tweaked for NAS workloads.

As a recap of what can potentially happen if you have a large RAID with 'normal' consumer grade HDD's (and by consumer grade I mean those without any form of Time Limited Error Recovery, or TLER for short):

  • Array starts off operating as normal, but drive 3 has a bad sector that cropped up a few months back. This has gone unnoticed because the bad sector was part of a rarely accessed file.
  • During operation, drive 1 encounters a new bad sector.
  • Since drive 1 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector.
  • The RAID controller exceeds its timeout threshold waiting on drive 1 and marks it offline.
  • Array is now in degraded status with drive 1 marked as failed.
  • User replaces drive 1. RAID controller initiates rebuild using parity data from the other drives.
  • During rebuild, RAID controller encounters the bad sector on drive 3.
  • Since drive 3 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector.
  • The RAID controller exceeds its timeout threshold waiting on drive 3 and marks it offline.
  • Rebuild fails.
  • Blamo, your data is now (mostly) inaccessible.

I went into much further detail on this back in the intro to the WD 3TB Red piece, but the short of it is that you absolutely should use a HDD intended for RAID when building one.

Need 128GB at 450 MB/s in your pocket?

We don't normally do reviews on USB flash drives, even if they are USB 3.0 based. But the Corsair Flash Voyager GTX turned out to be a bit different. Not only is this a USB 3.0 capable thumb drive, it is powered by an SSD controller, pushing performance as high as 460 MB/s in our testing! Add to that capacity options of 128GB and 256GB and you have a flash drive that really stands out from majority of the market.

FVGTX_hero.jpg

Check out the video review below that Allyn and I made about the Corsair Flash Voyager GTX 128GB flash drive and then continue on to see some more pictures and our quick benchmark results.

The Flash Voyager GTX is a bit large in pantheon of USB thumb drives but it's actually smaller than I expected it when I heard the capacity options available. You'll definitely be able to keep this around your neck or in your pocket without noticing it and you may still be able to keep it on your key ring. 

FVGTX_open.jpg

What do you do with 128GB or 256GB of flash drive? Well, other than the obvious of having a huge capacity drive for your "sneaker net" implementation at your home or office, you can investigate more interesting usage models. If you are looking for a more secure place to store sensitive files that you don't want on your home or work PC full time, just keep them on the Flash Voyager GTX and plug it into a USB 3.0 port when you want access. You'll get performance on par with an SSD but the ability to quickly disconnect it.

Introduction and Packaging

Introduction:

Late last year, Western Digital launched their My Cloud series, first with a single-drive My Cloud, and immediately followed up with a beefier small-office product, the 4-drive My Cloud EX4. Then earlier this year, they filled My Cloud gap (so to speak), with a 2-drive variant of the EX4 - the My Cloud EX2. As the EX2 was more of a business type of NAS, it commanded a bit of a price premium as compared to competing 2-bay NAS devices. The logical solution is was for WD to expand the standard My Cloud lineup upward by adding a 2-bay device to their existing consumer line.

DSC01552.JPG

The My Cloud Mirror is very similar to the My Cloud EX2. You get the bulk of the same features as compared with the EX2, but with some of the more workstation / enterprise features removed. Here's a couple of slides to help explain those differences:

Introduction

Samsung has certainly been pushing the envelope in the SSD field. For the past two years straight, they have launched class leading storage products, frequently showing outside-the-box thinking. Their 840 PRO series was an impressive MLC performer to say the least, but even more impressive was the 840 EVO, which combined cost-efficient TLC flash with a super-fast SLC cache. The generous SLC area, present on each die and distributed amongst all flash chips within the drive, enabled the EVO to maintain PRO-level performance for the majority of typical consumer (and even power user) usage scenarios. The main win for the EVO was the fact that it could be produced at a much lower cost, and since its release, we've seen the EVO spearheading the push to lower cost SSDs.

All of these innovations might make you wonder what could possibly be next. Today I have that answer:

DSC01485.JPG

If you're going "Hey, they just changed the label from 840 to 850!", well, think again. This SSD might have the same MEX controller as its predecessor, but Samsung has done some significant overhauling of the flash memory itself. Allow me to demonstrate.

Here's standard (2D) flash memory, where the charge is stored on a horizontal plane:

Samsung_27nm_NAND_cross-section_01-.jpg

..and now for 3D:

3D-NAND--.jpg

The charges (bits) are not stored at the top layer. They are stored within all of those smaller, thinner layers below it. You're still looking at a 2D plane (your display), so here's a better view:

The full line of (now legacy) Revo / Z-Drive series products.

With the recent acquisition by Toshiba, it was only a matter of time before OCZ revamped the RevoDrive line with their new flash. It just makes sense, as Toshiba can be obtained much more readily (and cheaply) since they are now an in-house source for OCZ. With the Vector 150 and Vertex 460 already driving 19nm Toshiba flash, we now have the RevoDrive 350:

We've looked at many hybrid options over the past few years. First we checked out Intel's RST Caching solution, introduced on the Z68 chipset. Then we looked into Seagate's first few rounds of SSHD's, which were basically a standard HDD with an 8GB cache tacked on to the controller. Despite larger adoption of SSD's taking place, Seagate continues to push further into the hybrid market, with the addition of dual mode caching and other advancements. Today we take a look at their most recent push:
