A-Data SSD S592 2.5” (128GB)
The A-Data SSD S592-series is available at 32GB, 64GB, 128GB, and 256GB capacities. We received the 128GB model for review.
The description on A-Data’s site mentions a lot of different performance enhancements compared to “regular SSDs.” The device is powered by Indilinx’s current controller together with 64MB cache memory, which, according to A-Data, leads to 250 MB/s maximum read (230 MB/s for 32GB and 64GB versions) and 170 MB/s maximum writes (150 MB/s for 32GB and 64GB capacities).
The drive almost delivered on these promises at 218 MB/s maximum read throughput on our X58-based test system and at least 170 MB/s write throughput—nice. However, our IOMeter-based streaming read/write testing resulted in a constant read maximum of 196 MB/s and sustained streaming write performance of 62 MB/s. This is still above-average I/O performance. We saw similar results under PCMark Vantage’s application benchmark, with its eight different test disciplines.
The 0.4W idle power also impresses, and we never measured more than 1.1W total power consumption during all of the power consumption tests. A-Data showed strong efficiency for streaming read operations and very good I/O operations. Keep in mind that our results only apply to the 128GB model, although the other capacity points shouldn’t differ too much.

shit review, the G1 is alot worse then the G2 over time/use and intel won't be giving the G1 the Trim command
Would have been helpful to have a hard drive in there for comparison just to reflect just how far SSDs improve performance.
Where are the comparisons at empty verses used? This is a key differentiator at the moment and you seem to have missed the point completely. Its not how well a drive performs out of the box its how far it degrades once time has taken its toll.
There is a lot missing from this article. TBH, I wouldn't use this as a basis for making a decision on what SSD to buy.
One of your competitors has a superb article on SSD that they published recently, that delves into new vs used performance, and a good explanation of TRIM, and why it's important.
IMO, this article is not up to the usual THG high standard.
Why is the Vertex doing so extremely bad in the write-test?? Just 74MB/s write?? Is that a typo and is it suposed to be 174MB/s?
Fail, Fail, Fail.
Once again THG resorts to lots of silly benchmarks but misses the point... I wouldn't pick a drive based on this roundup!
Where, or where are the degradation of write performance tests... Thinking where all the Flash blocks are used and write cycles become Write-Read-Write cycles. (heading off to AnandTech again...)
Where is the Patriot Torqx M28 SSD (128Mb cache & 10 year warranty) in this "roundup"??
If you want a fast boot drive for "desktop usage" you'll surely want more I/O performance emphasise.

... Thinking where all the Flash blocks are used and write cycles become Write-Read-Write cycles. ...
I meant Read-Modify-Write of course!!
It's like you guys haven't read Anand's articles on SSDs or intentionally ignoring it. SSDs with JMicron controllers are automatically crippled SSDs. At least until JMicron cleans up their shoddy work, but then they'd have to fight against a bad reputation.
