MyDigitalDiscount doesn't seem to have been satisfied with their performance BPX line or their value SBX line, and have now launched a BPX Pro, which looks to carry the budget pricing of the SBX while offering performance *higher* than the original BPX. How much faster is the BPX Pro than the BPX? That's what this review sets to find out, so let's get to it.

Today we take a quick look at an update to Toshiba's line of OEM SSDs. The first product to employ 96-layer 3D TLC NAND, the XG6:

I'm going to keep this one brief since this is to be an OEM-only product that is not expected to be available in retail channels. It's good to have some results out there since it will appear in many laptops and may result in the creation of a parallel retail product at some point in the future.

Ryan's Law may finally glut it's DRAM self in a Flash victory!

Subject: General Tech | August 1, 2018 - 01:17 PM |
Tagged: nand, DRAM, flash, ryans law

While this will not be a permanent situation, all signs point to a glut of NAND supplies soon driving prices down.  The Register lists a variety of reasons why this could occur, not least of which is the roughly half dozen NAND fabs that are either being built or close to coming online.  That is not the only factor increasing production, the move to 64-layer and 96-layer NAND, coupled with the move from TLC to QLC means more usable NAND comes off of every wafer.  Since all the major manufacturers are participating in these changes, and will continue to try to undercut the competitions pricing, it seems likely that prices are going to start to dip in the later half of the year.

$0.10/GB, here we come?

Intel, Micron Jointly Announce QLC NAND FLASH, 96-Layer 3D Development

Subject: Storage | May 21, 2018 - 04:31 PM |
Tagged: ssd, QLC, NVMe, nand, Intel, Floating Gate, flash, die, 1Tbit

In tandem with Micron's launch of their new enterprise QLC SSDs, there is a broader technology announcement coming out of Intel today. This release covers the fact that Intel and Micron have jointly developed shippable 64-Layer 3D QLC NAND.

IMFT_Micron 3D NAND.png

IMFT's 3D NAND announcement came back in early 2015, and Intel/Micron Flash Technologies have been pushing their floating gate technology further and further. Not only do we have the QLC announcement today, but with it came talks of progress on 96-layer development as well. Combining QLC with 96-Layer would yield a single die capacity of 1.5 Tbit (192GB), up from the 1 Tbit (128GB) capacity of the 64-Layer QLC die that is now in production.

This new flash won't be meant for power users, but should be completely usable in a general use client SSD, provided there is a bit of SLC (or 3D XPoint???) cache on the front end. QLC does store 33% more data per the same die space, which should eventually translate to a lower $/GB once development costs have been recouped. Here's hoping for lower cost SSDs in the future!

Press blast after the break!

Micron Launches 5210 ION - First QLC NAND Enterprise SATA SSD

Subject: Storage | May 21, 2018 - 04:30 PM |
Tagged: ssd, sata, QLC, nand, micron, enterprise

For those that study how flash memory stores bits, Quad Level Cell technology is a tricky thing to pull off in production. You are taking a single NAND Flash cell and change its stored electron count in such a way that you can later discriminate between SIXTEEN different states.

SLC MLC TLC QLC.png

...we're talking a countable number (dozens to hundreds) of electrons making the difference between a stored 0101 or 0110 in a given cell. Pulling that off in production-capable parts is no small feat, and doing so for enterprise usage first is definitely a bold move. Enter Micron:

5210_SATA_ION_2.5_bottom_transparent_labled_1000x667.png

The 5210 ION line is a SATA product meant for enterprise usages where the workload is primarily reading. This comes in handy for things like real-time data analytics and content delivery systems, where data is infrequently written but needs to be readable at latencies faster than what HDD's can provide.

These are 2.5" 7mm SSDs that will be available from 1.92TB to 7.68TB (yes, 2TB is the *smallest* available capacity for these!). The idea is to enable an easy upgrade path for larger data systems that already employ SATA or SAS (SAS systems are typically cross-compatible with SATA). For backplanes that are designed for slimmer 7mm drives, this can make for some extreme densities.

These are currently being sampled to some big data companies and should see more general availability in a few months time. Press blast from Micron appears after the break.

Introduction, Specifications and Packaging

Introduction:

When one thinks of an M.2 SSD, we typically associate that with either a SATA 6GB/s or more recently with a PCIe 3.0 x4 link. The physical interface of M.2 was meant to accommodate future methods of connectivity, but it's easy to overlook the ability to revert back to something like a PCIe 3.0 x2 link. Why take a seemingly backward step on the interface of an SSD? Several reasons actually. Halving the number of lanes makes for a simpler SSD controller design, which lowers cost. Power savings are also a factor, as driving a given twisted pair lane at PCIe 3.0 speeds draws measurable current from the host and therefore adds to the heat production of the SSD controller. We recently saw that a PCIe 3.0 x2 can still turn in respectable performance despite lower bandwidth interface, but how far can we get the price down when pairing that host link with some NAND flash?

180305-155833.jpg

Enter the MyDigitalSSD SBX series. Short for Super Boot eXpress, the aim of these parts is to offer a reasonably performant PCIe NVMe SSD at something closer to SATA SSD pricing.

Specifications:

  • Physical: M.2 2280 (single sided)
  • Controller: Phison E8 (PS5008-E8)
  • Capacities: 128GB, 256GB, 512GB, 1TB
  • PCIe 3.0 x2, M.2 2280
  • Sequential: Up to 1.6/1.3 GB/s (R/W)
  • Random: 240K+ / 180K+ IOPS (R/W)
  • Weight: 8g
  • Power: <5W

Packaging:

The MyDigitalDiscount guys keep things extremely simple with their SSD packaging, which is eaxctly how it should be. It doesn't take much to package and protect an M.2 SSD, and this does the job just fine. They also include a screwdriver and a screw just in case you run into a laptop that came without one installed.

Western Digital launched a few new NVMe SSDs at Mobile World Congress today:

SN720-SN520.jpg

To the left we have the WD PC SN720, a PCIe 3.0 x4 NVMe SSD boasting speeds of up to 3.4GB/s and IOPS up to 500k. Available capacities are 1TB, 512GB, and 256GB. To the right we have the WD PC SN520, a more power efficient variant running on half of the PCIe lanes, and with specs coming in at roughly half of its faster brother. Capacities are also cut in half, with the range dropping to 512GB, 256GB, and 128GB. Interestingly, all capacities are available in three M.2 form factors (2280, 2242, and 2230).

We don't have a specific part number for the controller, but WD told us they are manufactured on a 28nm process, employ 8 NAND channels, and use DDR4 RAM (not DRAMless). The controller is optimized for interfacing with WD (/Toshiba) BiCS NAND flash, meaning these SSDs should prove to be a well integrated solution.

Introduction, Specifications and Packaging

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:

180123-114944.jpg

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.

Crucial showed off the upcoming M.2 variant of its MX500 product, available in capacities up to 1TB. They also announced (press release after the break) that the MX500 will be available from 250GB up to 2TB capacities.

180109-153435.jpg

Here is Crucial's product tour video for the MX500:

We previously tested the 1TB MX500, and Crucial passed along a 500GB model that I was able to spot check to ensure there was no performance fall-off at the smaller capacities of this line:

Looks good so far, and nearly identical to the 1TB capacity across our entire test suite. We did also speak with Crucial reps (Jon and Jon) about the TRIM speed issues noted in our previous review. They are looking into replicating our testing and may be pushing out a firmware to help improve this metric moving forward.

We also saw some sweet looking new RGB Ballistix memory, due out shortly. More to follow there! Crucial's MX500 CES announcement appears after the break.
