ADATA launches XPG SX910 SSDs

ADATA launches XPG SX910 SSDs

ADATA's new XPG SX910 SSDs take advantage of new overprovisioning rules on SandForce controllers to boost capacities by seven per cent.

Memory specialist ADATA has announced a new entry in its 2.5-inch solid-state drive (SSD) line-up: the XPG SX910 family.

Based on an LSI SandForce SF-2281 controller mated to consumer-grade multi-level cell (MLC) NAND flash modules and boasting a SATA III 6.0Gb/s interface to the host machine, ADATA is aiming the XPG SX910 at the enthusiast end of the market with the promise of lessened overprovisioning without sacrificing performance.

According to ADATA's testing, the drive hits speeds of 550MB/s sequential read and 530MB/s sequential write with 50,000 input-output operations per second (IOPS) 4K random read and 85,000 IOPS 4K random write. Those are impressive figures, considering the company has tweaked the SandForce firmware to disable the usual seven per cent overprovisioning - a mechanism for sacrificing drive space to gain performance and longevity - to allow greater access to the capacity of the NAND flash chips on-board.

It's a trick which comes directly from SandForce owner LSI, which recently announced that it would allow OEMs to choose the level of overprovisioning the controller demands of the drive. The - predictable - result: most of LSI's SandForce customers choosing to drop the overprovisioning from 14 per cent to seven per cent - as ADATA has done for the XPG SX910.

Accordingly, the XPG SX910 is to be made available in 128GB, 256GB and 512GB capacities, all of which measure 9.5mm thick - making them suitable for use in laptops as well as desktops. Power draw is given as 0.5W idle and 1.2W active, with a five-year warranty included as standard. A 3.5-inch mounting bracket is also included.

UK pricing for the devices has yet to be confirmed, with US prices set at $189.99 for the 128GB, $379.99 for the 256GB and $749.99 for the 512GB model (around £122, £244 and £481 respectively, excluding taxes.)

£244 is too expensive for the 256gb drive when you consider you can get a samsung 830 256 for around the £160 mark.

What Pookie said! There is too little speed advantage for the price disparity.

Ah, makes sense now. Still a great deal, considering I bought the same drive for £250 in March 2012....... Really tempted to buy a second one just to have games installed and the OS on the other M4...........must resist

Novatech have the 256GB Samsung 830 for £145… → http://www.novatech.co.uk/products/components/harddrives-internal/solidstate/128gbandabove/Samsung/MZ-7PC256NEU.html

That's the 2nd one ordered to expand the games drive :)

Yeah, what is up with the price expansion as well? The ADATA 120GB version of the 128 last I saw runs around $120 on Newegg and you can get a Mushkin 120GB sandforce based drive (granted, with synchronous NAND) for under $100 for a 120GB drive. If you want people to buy them, price them the same as the drives with higher overprovisioning, or at most a very slight premium, like $5-15.
