Force 3 RAID 0 wayward ATTO benchmark ....

Although both read and write speeds reach c. 1GB/s, reads at block sizes of 4 - 32 KB drop well below writes, in fact not even matching a single Force 3 at 16KB.







I gather that these sizes are quite relevant to responsiveness and loading speed for many apps and processes (less so than for simple, large file transfers).



I've searched all over the net and not found a single ATTO result like it.



I've never been able to compare my PC with another SSD-equipped one, and given it's certainly very fast in I/O never thought to actually benchmark it (except in Crystaldiskmark, just to confirm is was more-or-less in the ballpark).



- Stripe size 32KB

- Writeback cache enabled in IRST [ETA >> v. 11.1.0.1006]

- Write-back caching enabled and write-cache buffer flushing disabled in device manager.



Happy New Year.
