ADATA Ultimate SU800 240GB SSD Review
IOMeter is heavily weighted towards the server side of things, and since we here at HWC are more end-user centric we will be setting and judging the results of IOMeter a little bit differently than most. To test each drive we ran 5 test runs per HDD/SSD (1, 4, 16, 64, 128 queue depth) each test having 8 parts, each part lasting 10 min with an additional 20 second ramp up. The 8 subparts were set to run 100% random, 80% read 20% write; testing 512b, 1k, 2k, 4k, 8k, 16k, 32k, 64k size chunks of data. When each test is finished IOMeter spits out a report, in that report each of the 8 subtests are given a score in I/Os per second. We then take these 8 numbers add them together and divide them by 8. This gives us an average score for that particular queue depth that is heavily weighted for single user environments.
IOMeter is not overly kind to TLC drives in general, nor SMI-based models in particular, and the SU800 is no exception. Plainly put, this drive is not meant for workstation type workloads, and anyone who tries will most likely kill the drive before its warranty is up – either by wearing down the NAND or simply by taking a hammer to it out of sheer frustration.
