ADATA Premier Pro SP920 256GB

Premier Pro SP920 256GB
Continuing its assault on the SSD market, ADATA has come out guns blazing with a brand-new lineup of drives. The Premier Pro SP920 family of 6Gbps SATA SSDs has a little something for everyone, in terms of capacity. Maybe you want a fleet-footed boot drive and nothing more. Perhaps the kinds of files you want to store on your new SSD is “all of them.” With capacities of 128GB, 256GB, 512GB, and big ol’ 1TB, the Premier Pro SP920 family has you covered. We split the difference and called the 256GB model into the station for questioning.

The 256GB SP920 certainly has an impressive rap sheet. Previous ADATA SSDs relied on SandForce silicon for their storage controllers, but the controller under the hood of the SP920 is Marvell’s 88SS9189. Like the SSD itself, this controller is new, shiny, and laden with tasty treats. We know you care deeply about performance, and the Marvell 88SS9189 has plenty. Sequential reads and writes peak at 560MBps and 360MBps, respectively, while random 4K reads and writes can top out at an obscene 96,000 IOPS/80,000 IOPS.
Better still, our test results showed that it makes no difference to this controller whether a particular workload is com- pressible or not.
Marvell’s controller also gives you NCQ, TRIM, and S.M.A.R.T. support, as it should, and it also has a hardware- based AES-256 encryption engine.
ADATA fills this drive with synchronous MLC NAND, set up in eight channels.
Although the SP920 is a slender 7mm thick, ADATA includes a spacer to fatten it up for 9.5mm bays. And because we’re all special little snowflakes, ADATA gifts every SP920 with a product key for Acronis True Image HD. (We found ours under the drive itself.) As our benchmark results show, the SP920 is a burner. What it won’t do, though, is burn up your budget; you can have the 256GB drive for about 62 cents a gig. That’s hot.
