Introduction:

Flash Memory Summit 2018 is on, and it's rapidly looking like the theme of the year is 'QLC'. QLC stands for Quad Level Cell, which is a bit of a misnomer since there are actually 16 voltage levels of a QLC cell - the 'quad' actually relating to the four bits of data that can be stored at any specific location.

Doubling the number of voltage states allows you to store 33% more data in a given number of flash cells, but comes at a cost. The tighter voltage tolerances required and higher sensitivity to cell leakage mean that endurance ratings cannot be as high as TLC or MLC, and programming (writing) requires greater voltage precision, meaning slower writes. Reads may also see a slight penalty since it is more difficult to discriminate more finely grained voltage thresholds. SSD makers have been trying to overcome these hurdles for years, and it seems that Intel is now the first to crack the code, launching their first mainstream QLC SSD:

Specifications:

Specifications are not earth shattering but respectable for a budget-minded NVMe SSD. 1.8GB/s sequentials and 250,000 IOPS fall well within NVMe territory. The write figures may be higher than expected given this article intro, but Intel has a few tricks up their sleeves here that help them pull this off:

cache.png

While not specifically called out in the specs, Intel has implemented a large dynamic write cache to help overcome slower QLC media write speeds. The idea here is that in the vast majority of typical usage scenarios, the user should never see QLC speeds and will only ever be writing to SLC. The dynamic cache is created by simply operating sections of the QLC media in SLC mode (1TB of QLC = 256GB of SLC). Intel could have gone higher here, but doing so would more negatively impact endurance since erasing blocks of cells wears the flash similarly regardless of the mode it is currently operating in.

Simple packaging. Nothing to write home about.

Introduction:

Intel has been doing great with their Optane / 3D XPoint products lately, but what about NAND? Samsung had been leading the pack with their VNAND for a few years now, forcing competitors to struggle to keep up on the capacity, performance, and endurance fronts. Intel's 3D NAND production (announced in 2015) is finally starting to come into its full stride, with 64-layer TLC NAND shipping in their 545S in mid 2017. With SATA essentially covered, PCIe NAND solutions have been a bit rough for Intel. The SSD 600p was their first M.2 PCIe product, launching over a year ago. While it was cost-effective, it was not a stellar performer. This left the now extremely dated SSD 750 as their flagship NAND product. It was great for its time, but was only available in HHHL and U.2 form factors, precluding any possibility of mobile use. With their 3D NAND finally in a good position, what Intel really needed was a truly solid M.2 product, and I'm happy to report that such a thing has finally happened:

180123-155708.jpg

Behold the Intel SSD 760p Series, currently available in 128GB, 256GB, and 512GB capacities, with 1TB and 2TB coming later in Q1 2018. Today we will be reviewing all currently available capacities.

This chart makes me happy. Finally, an Intel M.2 SSD with competitive specs! Note that the performance specs all come in at 2x the 600p, all while consuming half of the power of the older model. Endurance remains the same, but the 600p's problems were with performance, not endurance.

Packaging:

180123-155639.jpg

Packaging was very similar to that of the 600p and other Intel products. Simple and no frills. Gets the job done.

Introduction:

Samsung launched their 850 line of SSDs in mid-2014 (over three years ago now). The line evolved significantly over time, with the additions of PRO and EVO models, capacity expansions reaching up to 4TB, and a later silent migration to 64-layer V-NAND. Samsung certainly got their money's worth out of the 850 name, but it is now time to move onto something newer:

Specifications:

specs.png

Of note above is a significantly higher endurance rating as compared to the 850 Series products, along with an update to a new 'MJX' controller, which accounts for a slight performance bump across the board. Not mentioned here is the addition of queued TRIM, which is more of a carryover from the enterprise / Linux systems (Windows 10 does not queue its TRIM commands).

Packaging:

180123-112150.jpg

Aside from some updated specs and the new name, packaging remains very much the same.

Samsung's T5 provides a mobile storage junkies fix

Tagged: USB 3.1 gen 2, T5, Samsung, portable, 500gb, 2TB

Hopefully Samsung changes its naming schemes before we hit T1000 but for now, as many people know a T5 is stronger than a T3.  If you missed Al's review, you should take a peek before heading to The Tech Report to benefit from his wisdom.  With portable drives, or most drives for that matter, the metric that we care the most about is real world usage which is what Robobench is intended for.  In order to properly test this USB 3.1 Gen 2 drive, TR picked up an addin card with the most common Gen 2 chip, the ASMedia ASM1142 controller and tested the transfer speeds for both compressible and non-compressible data.  Drop by for a look at how the Samsung T5 performed.

"Samsung has refreshed its portable SSD lineup with 64-layer V-NAND and an aluminum unibody. We take the new T5 external for a spin to see if it lives up to the legacy of the T1 and T3."

Introduction:

Back in January of 2016, Samsung launched the Portable SSD T1. This was a good way to get more of their VNAND flash out into the market in the form of a speedy and portable USB connected SSD. The launch went so well that they followed it up with the T3 in early 2016. While the T1 maxed out at 1TB of capacity, the T2 pushed that to 2TB, which remains the market sweet spot for max portable capacity today. As increased flash densities come out, it became time for Samsung to refresh the lineup:

170814-152341.jpg

Meet the Samsung Portable SSD T5. This new version is ever so slightly smaller than the T3, while packing a 256Gbit die version of Samsung's 64-layer VNAND, along with a newer USB controller that should help get closer to the internal SATA 6Gbit speed of the device.

Specs:

specs.png

Most specs are nearly identical to the T3, with a notable increase to 540MB/s throughput, thanks to the faster interface capability.

Packaging:

170814-152408.jpg

Straightforward packaging with a notable inclusion of both Type-C to A and C to C cables. The T3 and T1 came with only Type-A.

Introduction:

Micron paper launched their 5100 Series Enterprise SATA SSD lineup early last month. The new line promised many sought after features for such a part, namely high performance, high-performance consistency, high capacities, and relatively low cost/GB (thanks to IMFT 3D NAND which is now well into volume production since launching nearly two years ago). The highs and lows I just rattled off are not only good for enterprise, they are good for general consumers as well. Enterprises deal in large SSD orders, which translates to increased production and ultimately a reduction in the production cost of the raw NAND that also goes into client SSDs and other storage devices.

170130-192150.jpg

The 5100 Series comes in three tiers and multiple capacities per tier (with even more launching over the next few months). Micron sampled us a 2TB 'ECO' model and a 1TB 'MAX'. The former is optimized more for read intensive workloads, while the latter is designed to take a continuous random write beating.

I'll be trying out some new QoS tests in this review, with plans to expand out with comparisons in future pieces. This review will stand as a detailed performance verification of these two parts - something we are uniquely equipped to accomplish.

Kicking off the storage announcements at CES 2017, Kingston announced a 2TB thumb drive:

dtgt.image_resize.jpg

Ok, well it's a bit big for a thumb drive, but it is definitely a high capacity portable SSD with a narrower profile (width wise) than a Samsung T3, and is meant to be plugged directly into a USB port. Thickness may be an issue for some applications, but I assume they would include a short extension for those trying to plug into tighter spaces like at the rear of a PC case. The release was light on details, particularly performance, though I'd expect these to be able to do a few hundred MB/s on sequentials at a minimum. More should come out about this and other Kingston products later in the week.

*edit* Here's a couple of pics I snagged at one of the events here:

Al has already exhaustively covered the new Samsung 960 Pro in his latest article, which also happens to be the premiere of PC Perspective's new storage testing suite.  An in depth discussion of the new testing methodology can be found on the third page and you can expect to hear about it on our podcast tomorrow and perhaps in a standalone article in the near future.  Several comments have inquired as to the effect this drive would have on a system used for gaming or multimedia and how it would compare to drives like the Intel 750 and DC P3700 or OZC's RD 400.  The best place to find those comparisons is over at The Tech Report, their RoboBench transfer test features a long list of drives you can look at.  Check it out once you have finished off our article.

Introduction:

Just under a year ago we published our review of the Samsung 950 PRO, their first foray into NVMe SSD territory. Today we have a 960 PRO, which strives to be more revolutionary than evolutionary. There are some neat new features like 16-die packages and a Package-on-Package controller/DRAM design, all cooled by a copper heat spreading label! This new model promises to achieve some very impressive results, so without further delay, let's get to it!

161018-080624.jpg

Specifications:

specs-2.png

Specs have not changed since the announcement. Highlights include

  • A new 5-core Polaris controller (with one die solely dedicated to coordinating IO's to/from the host)
  • 4-Landing Design - It's tough fitting four flash packages onto an M.2 2280 SSD, but Samsung has done it, thanks to the below feature.
  • Package-on-Package - The controller and DRAM are stacked within the same package, saving space.
  • Hexadecimal Die Packages - For the 960 Pro to reach 2TB of capacity, 16 48-layer MLC V-NAND packages must be present within each package. That's a lot of dies per package!

Introduction

Western Digital launched their My Passport Wireless nearly two years ago. It was a nifty device that could back up or offload SD cards without the need for a laptop, making it ideal for photographers in the field. I came away from that review wondering just how much more you could pack into a device like that, and today I get to find out:

DSC01265.jpg

Not to be confused with the My Passport Pro (a TB-connected portable RAID storage device), the My Passport Wireless Pro is meant for on-the-go photographers who seek to back up their media while in the field but also lighten their backpacks. The concept is simple - have a small device capable of offloading (or backing up) SD cards without having to lug along your laptop and a portable hard drive to do so. Add in a wireless hotspot with WAN pass-through along with mobile apps to access the media and you can almost get away without bringing a laptop at all. Oh, and did I mention this one can also import photos and videos from your smartphone while charging it via USB?

Specifications

  • Capacity: 2TB and 3TB
  • Battery: 6,400 mAH / 24WH
  • UHS-I SD Card Reader
  • USB 3.0 (upstream) port for data and charging
  • USB 2.0 (downstream) port for importing and charging smartphones
  • 802.11AC + N dual band (2.4 / 5 GHz) WiFi
  • 2.4A Travel Charge Adapter (included)
  • Plex Media Server capable
  • Available 'My Cloud' mobile apps

Packaging
