Western Digital Caviar Black 1TB Hard Drive Review

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 que 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 que depth that is heavily weighted for single user environments.


That marvelous X-25 once again compresses our numbers too darn much to make a good judgment on this drive's performance…so let’s yank it and a few others and “zoom in” to get a better feel for this drive.

Its not that unexpected to see the VRaptor eat all the other platter based drives for lunch as it is a 10000RPM drive, but this 1TB Black beast does post some very admirable numbers. Interestingly it once again beats its little brother, albeit it is awfully darn close; but as they say “a win is a win” regardless of the distance between first and second!
