IOMETER

IOMeter is heavily weighted towards the server end 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 (1,4,16,64,128 queue depth) each test having 8 parts, each part lasting 10 min w/ 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 reports 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 by 8. This gives us an average score for that particular queue depth that is heavily weighted for single user environments.

Anyone using the TL100 in a workstation environment is going to have a bad day. Though to be fair they will have a bad day if they use any TLC NAND based model. Basically the SLC-cache is going to be exhausted and the drive’s fragile NAND is going to be hammered mercilessly. These results also point to why just because a controller does not ‘need’ a external RAM cache does not mean that it should not come with any external RAM cache.
