Specifications, Pricing and Availability

ADATA has released four capacity sizes in the S511 Series. The capacities are standard SandForce sizes; 60GB, 120GB, 240GB and a massive 480GB. Today we're looking at the 240GB, a good price, performance and capacity size that is very popular with both notebook and desktop users.

ADATA is accurately listing performance information differently for each capacity size. Our 240GB sample shows a read speed of 550MB/s and a write speed of 520MB/s. The IOPS is rated at 60K for 4K Random Write aligned and a peak IOPS write of 85K. Users should see the 85K peak as a test is started and then after a short period of time the performance dips to 60K.

Newegg already lists the ADATA S511 Series drives. The 60GB is available today for 154.99, the 120GB for 189.99, the 240GB that we are reviewing today for 454.99 and the big dog 480GB for 1399.99.

These prices are very competitive to competing drives like the OCZ Technology Vertex 3 and in many cases, the ADATA versions cost less. This is very good for the consumer since ADATA's ability to manufacture their own products will keep them ahead of many other companies that are just reselling products made by third-party manufacturers.

When it comes to value-added goodies, ADATA includes a three year warranty. The accessory package also includes a desktop adapter bracket.
