Re: HDD; RPM Or Size? (Score: 1) by chazz(cwangersky@spamcop.net) on Wednesday, March 12 @ 00:12:14 UTC (User Info | Send a Message)
In theory, 15000 RPM HDs should have double the transfer rate of 7200. Yes? check it -- they don't.
10k RPM disks should have 50% higher transfer rates than 7200. The actual number (from artificial benchmarks, I grant you -- but there doesn't seem to be any other way to avoid burst transfer from on-disk buffer) is about 10-15% higher.
Likewise 7200 RPM should be 35% faster than 5400. Is it? My benchmarks indicate 15-20%.
