My Tech Tips


Disk Perf

SSDs are moving more towards mainstream as their price point comes down and their size increases.
I've been keen on the technology from it's inception, but as yet, haven't laid out the cash.
Other people I know have and I'm posting these shots of their disk performance.
These are from non-lab-condition tests, so it's a range of OS, and I can't vouch for what was running in the background.

So there you have it. Some reference points for getting an idea about what performance you MIGHT get.
