Read Performance: Random 8MB reads
...
The idea is to test how well write performance holds up under increased space utilisation. For example, if we write 120GB to the first 20% of the disk's logical blocks (randomly overwriting), how does the drive fare? We'd hope that when utilisation isn't too high, the drive's FTL would be able to efficiently erase recently overwritten LBAs and keep up with the write load.
Before each run, the disks were trimmed using hdparm. Perhaps a secure erase would have been better, but most drives appeared to regain full write performance this way. Notably, the Mushkin one did not (the 100% test was first, followed by 20,40,60%...).
