LAS VEGAS, NV -- Yesterday we told you about SSD manufacturers staying clear of 64-layer 256Gb products in hopes of hitting a home run with 512Gbit die later in the year. Today we found out that Adata's gamer product division, XPG, will take advantage of the 256Gb supply to update the aging SX8x00 series.
The new SX8200 uses Silicon Motion's SM2262 8-channel controller with a PCie 3.0 x4 interface and the same flash memory mounted in the speedy Crucial MX500 SATA SSD. The combination gives users up to 3,200 MB/s sequential read and 1,700 MB/s sequential write speeds. Adata didn't divulge any random performance details other than a canned screenshot of CrystalDisk Mark showing 76.97 MB/s 4KB read and 232 MB/s 4KB writes. We don't use the software to test in the lab, but the results are very quick in comparison to others we've seen at CES 2018.
The SX8200 will ship in the standard sizes we usually see, 240GB, 480GB, and 960GB. There will also be a 2TB model available with 1.92TB of user addressable space after overprovisioning. The SX8200 will join the Samsung 960 Pro in the 2TB realm, and others are sure to follow.
XPG plans to bring the SX8200 to market in the coming weeks and we may have the series to test by early February. We spoke with the company extensively about other NVMe products in the works using Silicon Motion and alternative controller technology. Adata plans to replace most existing M.2 SSDs around June, just in time for Computex. The timeline fits with what we heard from other SSDs manufacturers that buy, rather than produce, NAND flash.
XPG placing the SM2262 controller in an 8000 series product leaves room for the faster SM2262EN controller for the 9000 series. The two controllers are physically the same but the SM2262EN uses advanced cache technology to increase performance even further. We've yet to see a SM2262EN at CES 2018, but we'll meet with Silicon Motion later in the week.

Is it normal to not run CrystalDisk in the lab?
It almost sounds like they are trying to hide something.
Fast? Yes. But that price...ouch!Reply
Sorry if this question is very basic ... do SSD's suffer at all from excessive read/writes? Is there a limit? Are they more for 'read mostly' requirements?Reply
All ssds "suffer" from write endurance.Reply
With SLC based ssds each cell that is written to has 2 values; 1 or 0.
With MLC based ssds each cell that is written to has 4 values; 00, 01, 10, 11.
With TLC based ssds each cell that is written to has 8 values; 000, 001, 010, 011, 100, 101, 110, and 111.
Over time the cells lose their ability to hold the correct charge and for example a TLC SSD that writes a 001 might lose the voltage required for the 001 and become a 000.
This decay on voltage is bad for your data.
SLC with only 2 values has the highest write endurance due to having the largest possible gap between its 2 states.
But for the most part write endurance isn't a factor unless you have an incredibly small drive, like a 128 gigabyte ssd and you constantly write and erase the entire drive each day.
Even my ancient 1 terabyte Samsung 840 Evo should last 60+ years at 50 gigabytes of writes per day.
By then I hope to have a 1 petabyte drive, at least lol.
Explains write endurance in much more detail.
Reading data does not harm the cells at all.
Excellent. Thanks Derekullo!Reply
