ADATA Launches XPG SX9000: 2.8 GB/s Seq. Read, Marvell Controller, Up to 1 TB of MLCby Anton Shilov on August 19, 2017 9:00 AM EST
ADATA has announced its new SSD aimed at the very high end of the market. The new flagship XPG SX9000 drives are based on the Marvell 88SS1093 BTB2 controller and are paired with Toshiba’s 2D MLC NAND flash memory. Later on, the company plans to switch to Toshiba’s 3D MLC NAND for a product that will succeed the SX9000 SSD series.
The ADATA XPG SX9000 SSDs use the Marvell 88SS1093 BTB2 controller, which sports three processor cores and 8 NAND channels, with 4 banks per channel for 32 targets in total. The IC is an improved version of the 88SS1093 with higher frequencies and performance to boost speeds of higher-end SSDs. The 88SS1093 BTB2 supports a Marvell’s third-generation ECC technology based on the LDPC algorithm and uses PCIe 3.0 x4 interface.
The new XPG SX9000 drives are to be available in 256 GB, 512 GB, and 1 TB configurations in the M.2-2280 form-factor. The SSDs use DRAM buffers for additional performance, and come with a very basic heat spreader to further prop up performance in systems that provide adequate cooling. Speaking of performance, ADATA promises up to 2.8 GB/s sequential read speed as well as up to 1.45 GB/s sequential write speed for the top-of-the-range 1 TB model. As for random read/write performance, ADATA lists 310K/240K IOPS for the most advanced model.
Reliability is another thing that ADATA is taking serious when it comes to the XPG SX9000. The drives are rated for up to 1 PBW (terabytes to be written) and two million hours MTBF, which in turn is coupled with a five-year warranty.

ADATA has not set recommended prices of the XPG SX9000 series just yet. What we do know is that the drives are hitting the shelves in the coming weeks and expect their prices to be competitive against the obvious rivals — the Samsung 960 Pro and the Samsung 960 Evo families of SSDs.
Otherwise, as previously stated, ADATA is also looking at releasing 3D NAND versions of the drive farther down the line. 3D NAND has a number of advantages over 2D NAND, but it's not ideal for all possible applications at the moment, particularly due to its high density, which conflicts with the need for multiple NAND packages to maximize parallelism and performance on high-end SSDs. All things considered, this is why ADATA decided to go with a new Marvell controller as well as Toshiba’s 2D MLC NAND for the XPG SX9000 SSD. Eventually, the company promises to use the same controller for a high-end 3D NAND-powered drive, but that is something that is going to happen towards the end of the year at best.

bill.rookard - Saturday, August 19, 2017 - linkUmm.... I think there might be a typo there.
"The drives are rated for up to 1 TBW (terabytes to be written) and two million hours MTBF, "
That means that you can fill the drive once on a 1TB drive and the warranty is void? I see on the chart the 1TB drive is rated for... 1000TB? Perhaps you mean 1PBW? :)
justaviking - Saturday, August 19, 2017 - linkI noticed that, too. You beat me to it.
I thought... buy a 1TB drive, fill it once, and it's dead? LOL
Yes, 1,000 TBW.
XZerg - Saturday, August 19, 2017 - link"for up to 1 PBW (terabytes to be written) and"
TBW was changed to PBW but the "terabytes" in brackets is still the same.
Demon-Xanth - Monday, August 21, 2017 - link1TBW sounds perfectly reasonable for a 1TB PROM...
Gothmoth - Saturday, August 19, 2017 - linknice i have a 90s feeling.
whoever came up with the fake lensflare in the product photo.. kudos!!
eek2121 - Monday, August 21, 2017 - linkWhat's really sad is that the background is a single photoshop filter that takes like 2 seconds to add.
Samus - Saturday, August 19, 2017 - linkLegit NAND, legit controller, legit warranty, lets just hope legit firmware.
Magichands8 - Saturday, August 19, 2017 - linkAnd illegit form factor and I'm sure price as well. Instant fail.
Lord of the Bored - Sunday, August 20, 2017 - linkAnd then it will be ... 2 legit 2 quit?
Demon-Xanth - Monday, August 21, 2017 - linkDoesn't seem like long ago that those would have been pretty good specs for RAM.
