ADATA XPG SX900 256GB SSD Review

13 thumbs up
Our Test Methods: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. Out testbed's motherboard was updated with the latest UEFI available as of press time and AHCI (or RAID) mode was enabled. The SSDs were secure erased before testing and left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, PCMark 7, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

IOMeter
I/O Subsystem Measurement Tool

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance for the average end user. That said, we do think IOMeter is a reliable gauge for relative available throughput within a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you can't with most other storage benchmark tools available currently.

In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and another with 4K transfers, 100% random, 100% writes.






The ADATA drive scored in the middle of the pack with the IOMeter default access test, but it is worth noting that it was by far the most consistent in terms of IOPS as the number of concurrent I/Os increased. In our custom workstation test, the XPG SX900 followed a similar shape as the rest of the field, but as the concurrent I/Os increased, it nudged past the other contenders and finished with the highest IOPS of the group.



In terms of total MBps, it also scored the best overall in the workstation test while posting a solid but unspectacular score in the default test.

Might put one in my system...

Been thinking about getting one myself, but with so many out there to choose from...not sure who the leaders are. Always been a WD fan, but the one I had in my laptop didn't really seem to perform very well. Any advice on which brands are better?

Thanks

I have an Adata SATA-II 120GB drive now. I t has good performance and is reliable too. I wouldn't hesitate to buy another SSD from them.

Id like to have one of these to swap out my 64gb Kingston SSD with.

I don't understand why SSD is so damn expensive compared to HDD..

Type of memory it uses. Non-volatile flash memory. Spindles are cheap :P
