Re: [hard drive] CDM tests have me worried...
said by dolphins:What you're seeing there with the widely ranging results on the 4K random read is OS and drive caching. 50 MB is too small to get accurate results. I'd use the 1 GB test as a more accurate baseline.
I'm concerned with the significant drop in performance between read and write and also between sequential and random?
The only thing that looks odd to me is the gap between sequential read and write (in my experience, mechanical drives are usually quite close on sequential read/write speeds). I'd chalk that up to either chipset quirks or running it in safe mode.
