A-Data S592 128GB
The new S592 belongs to A-Data's S500 series of high-performance drives. This new series is available in 32GB, 64GB, 128GB and 256GB capacities. A-Data claims a read and write speed of 250MB/s and 170MB/s respectively, for the 128GB and 256GB models. The 32GB and 64GB models are slightly slower with read and write speeds of 230MB/s and 150MB/s.
The claimed throughput specs are roughly the same as the OCZ Vertex series, at least for the 128GB and 256GB versions anyway. Therefore it comes as little surprise to find that the A-Data S592 makes use of the Indilinx (IDX110) Barefoot SSD controller with the standard 64MB cache. Just like the Vertex, the S592 uses the same Samsung K9HCG08U1M-PCB0 memory chips.
The major difference between the A-Data S592 128GB and the OCZ Vertex, Vertex Turbo and even the Agility is in their firmware. This difference extrapolates to other relevant areas such as support. For example, OCZ provides their customers with ongoing support through updated firmware and even tools to trim the drives, whereas A-Data offers nothing.
Furthermore, the A-Data website lists almost no specifications for the S592, so we'll just have to assume they are similar to other Indilinx Barefoot SSDs. Availability shows a similar story with none of the A-Data online retail partners offering the drives when we were working on this review.
What we can tell you is that the A-Data S592 comes in a durable lightweight black plastic case, which we feel is of better quality than that of the OCZ drives. The advantage to using a plastic case is that it won’t scratch as easily. After just a few installs our OCZ drives using aluminum cases look as though they have been through a war zone.
