The ultimate in SSDs? Adata's new SU900

Adata have added a new series of SSDs to their Ultimate lineup, the SU900, which ranges from the 256GB model sent to The Tech Report to review straight through to a 2TB model.  This incarnation uses 3D MLC flash but retains the Silicon Motion SM2258 controller which was used on the SU800s. In testing the drive surpassed the previous Ultimate drive but did not quite reach the performance levels of the Samsung 850 EVO in some benchmarks, however it did in the actual usage testing.  If you are looking for a drive in that class and have concerns about the longevity of TLC flash, this drive is worth a look.

Adata's Ultimate SU800, 3D Micron NAND and a Silicon Motion controller

Adata's Ultimate SU800 512GB SSD is somewhat of a mixed bag, at $0.27/GB it is not exactly inexpensive nor does it take advantage of some of the SM2258 controllers advanced features, on the other hand it does use Micron's 3D NAND, offer a dynamic SLC cache and is overprovisioned by 64GB.  The Tech Report put this SATA SSD to the test in a barrage of benchmarks to see how its performance compared to other SSDs, both SATA and PCIe.  Check out their results right here.

CES 2016: Silicon Motion Updates SM2246EN for 3D NAND, Teases TLC and PCIe

Silicon Motion has updated their popular SM2246EN controller to support MLC 3D NAND from IMFT and SK Hynix:

The SM2246EN acts as a gateway for third parties to make their own SSDs. Adding support for 3D NAND is good news, as it means we will be able to see third party SSDs launch with 3D flash sourced from Intel, Micron, or SK Hynix. Another cool tidbit is the fact that those demo units in the above photo were equipped and operating with actual 3D NAND from Intel, Micron, and SK Hynix. Yes, this is the first time seeing packaged MLC 3D NAND from a company other than Samsung. Here are some close-ups for those who want to read part numbers:

Another question on non-Samsung 3D NAND is how does its performance stack up against planar (2D) NAND? Silicon Motion had a bit of an answer to that question for us:

Keep in mind those are results from pre-production firmware, but I was happy to see that my prediction of IMFT 3D NAND speeds being effectively equal to their previous 2D flash was correct.

To knock out some other info overheard at our briefing, Silicon Motion will also be making an SM2258, which will be a TLC 3D NAND variant of the SM2256. In addition, we saw the unreleased SM2260:

...which is Silicon Motion's PCIe 3.0 x4 SSD controller. This one is expected to surface towards the middle of 2016, and it is currently in the OEM testing stage.

Lots more storage goodies coming later today, so stay tuned! Full press blast for the updates SM2246EN after the break.
