HD Tune – Sequential Write Tests The synthetic benchmark
HD Tune is more widely known.
Minimum write speed is only noticeably worse with 16k stripe size.
Max write highest with 32k, the smaller stripe sizes a bit slower than the others.
The average write speed between slowest and fastest is ~16.7Mb/s; not that noticeable.
Access times for read actions are lowest with the smallest stripe size, according to this benchmark.
HD Tune – Random Write Tests Random write performance with the 4k stripe size is 7x faster than the slowest competitor; if all you do is write 512 byte files, 4k stripe size should be your choice… what? you don’t have that many 512 byte files?
With 4k stripe size performance is highest with 16k, the others are pretty much on par, except for 128k.
64k does best in this benchmark, 128k is even slower than 4k stripe size in this write test.
And here’s why you don’t want a 4/8k stripe size RAID 0 , even if the smaller file chunk random performance is 7x faster, if you randomly write larger files to your RAID array, you don’t want to get stuck at <50mb>
Again throwing all throughput benchmarks together in a single chart we come up with:
128k is not the fastest according to HD Tune, you’ll get better results with 64 and 32k.
I'll be upgrading soon (or at least after you publish the new Cooler roundup ) and I'm undecided as to an OS drive.
260 Euro can get you a very fast, single, simple to use SSD.
