ATTO Disk Benchmark

The ATTO disk benchmark tests the drives read and write speeds using gradually larger size files. For these tests, the ATTO program was set to run from its smallest to largest value (.5KB to 8192KB) and the total length was set to 256MB. The test program then spits out an extrapolated performance figure in megabytes per second.


The SSD is up against the best of the best when it comes to 3.5” SATA drives and I think its safe to say 95MB/s write and 105MB/s read is very impressive. The fact that it does all this while using almost no electricity and making absolutely no noise makes it all the more impressive and you can certainly see the future is very bright for SSD’s.


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 reporst 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.


WOW. It is easy to see that the G.Skill walked away with the IOMeter performance crown. To put into perspective how massively huge this win was, the Velociraptor has shown to perform as well as many 15Krpm SCSI drives in the IOMeter tests and this little SSD stomped the Velociraptor worse than a turtle being run over by a hummer!
