ADATA on Thursday introduced its highest-performing SSD to date, featuring sequential read speeds of up to 3.5 GB/s and random read speeds of up to 390K IOPS. The enthusiast-class PCIe 3.0 x4 drive, whose formal launch had been expected for quite a while, is powered by Silicon Motion’s range-topping controller.

The ADATA XPG Gammix S11 Pro is based on Silicon Motion’s SM2262EN controller, which is a seriously revamped version of the SM2262 (eight NAND channels supporting up to 800 MT/s data transfer rates, four ARM Cortex-R5 cores, NVMe 1.3, LDPC ECC, RAID engine, etc.) that operates at higher clocks and features some additional firmware-based optimizations to drive performance up.

SMI officially introduced this controller in mid-2017, but the chip took a long time to see adoption as we’ve only recently seen SSD vendors use it. ADATA is one of the adopters of the SM2262EN that have decided to pair it with proven 64-layer 3D TLC NAND memory in a high-end SSDs. Over time, we expect the controller to be used with other types of flash as well.

The XPG Gammix S11 Pro drives come in 256 GB, 512 GB, and 1 TB configurations, all featuring a PCIe 3.0 x4 interface. The SSD is outfitted with the company’s aluminum heat spreader to ensure consistent performance (assuming that airflows in the PC case are organized properly).

Speaking of performance, ADATA’s numbers are similar to those published by Silicon Motion: up to 3.5 GB/s sequential read speed and up to 3 GB/s sequential write speed when SLC caching is used (data based on CDM benchmark), as well as up to 390K/380K random read/write 4K IOPS.

Moving on to endurance and reliability of the Gammix S11 Pro SSDs. The new drives are covered with a five-year warranty and are rated for 160 TB, 320 TB, as well as 640 TB to be written, depending on the SKU.

ADATA did not disclose when it plans to start sales of the XPG Gammix S11 Pro SSDs, but keeping in mind that competing products are already here, it is in the company’s best interest to start shipments of the drives as soon as possible.

When it comes to pricing, the 256 GB version has an MSRP of $110, the 512 GB SKU carries a price tag of $170, whereas the 1 TB model is set to be priced at $270.

    Ahh, finally an SSD that can take the hot air in my case and blow cold air on my CPU! Can't wait to see what 2019 will bring us!

    The SSD isn't even installed, in that image. Talk about a bad photoshop.

    They've broken through the longstanding physics problem of reversing entropy and were even so humble as to not flaunt it as the major accomplishment in their marketing materials.

    You're thinking small. I'm getting an array of these to replace my AC.

    ADATA broke the second law of thermodynamics via a single poorly rendered image. That's quite an achievement indeed.

    be kind. everyone knows that if you can imagine it, you can do it. like levitating. or eating brussel sprouts.

    The fast looking car disjointedly floating above the surface of a road inside a tunnel while expelling a blue glow from its exhaust system is one of the most original ways of conveying the idea of a speedy computer product that I've ever seen. Everyone knows that computer data storage is basically comparable to transportation in every way. I'm surprised that no other company has thought up a similar marketing strategy yet. I have no doubt that the car image will land almost as many sales as the unheard of idea of putting a letter X in the product name.

    Dude, can your SSD support a car on top of it?

    Jokes aside, I think that Adata makes solid, competitive stuff. Its SX8200 NVMe SSD is pretty good.
  • Valantar - Friday, December 14, 2018 - link

    I find it especially interesting that the tunnel the car is floating through is very clearly a railway/light rail tunnel. I suspect that is done to showcase the versatility of the drive - "Not only is it as fast as a supercar, but it's as versatile as a flying supercar that can navigate railway tunnels!"
  • jonup - Friday, December 14, 2018 - link

    you forgot to mention that the car is going straight while the wheels are fully locked to the left.

    @Bravadu, ADATA also launched SX8200 PRO the other day with the same controller. Which brings up the other geniusity of ADATA - having virtually the same drives marketed under two different products. Like SX8200 and S11 were virtually the same, SX8200 PRO and S11 PRO are identical.
