The benefits of solid-state storage are plain to see, but even at today’s price levels, it’s not the cheapest way to hold data on your PC.
Hard disk prices are currently high, though, and if you look around you can find smaller capacity drives for well under £100.
The A-DATA S599 is available from 64GB for around £90. That’s far from being the cheapest SSD around, but it does promise good performance, up to 280MBps, still decent enough for the SATA 3 Gbps standard.
In our tests, it reached peak sequential read speeds in the ATTO benchmark of 286MBps, and writes of 271MBps.
The drive uses a SandForce SF-1222 controller, and as such garners wildly optimistic benchmark results in certain tests, such as the ATTO above.

But the cache-less design of SandForce-based SSDs does have one mooted benefit that becomes apparent with smaller drives such as this 64GB example: performance remains consistent across capacity choices, unlike other drives that only tend to perform at their best with larger capacity drives.
CrystalDiskMark was not so kind to the A-DATA S599, giving top sequential reads and writes of 200 and 101MBps respectively.
If you use the CDM test’s default 0s or 1s data, though, the figures rise to 267MBps read and 259MBps sequential write.
Low-level file juggling is handled well, though, with the CDM random-data test giving 100MBps for reads and writes in the 4k QD32 test.
AS SSD scored the drive with 390 of its points, a relatively average result these days. This benchmark showed sequential reads/writes as 200/95MBps. But its multi-threaded test, using 64 against CDM’s 32, gave figures of 108MBps read and 91MBps write.
Peak IOPS from the AS SSD test were 28k IOPS reads and 23k IOPS writes.
