Hi, I've decided to purchase the new Intel 320 series 40GB SSD disk as my system drive on Dell Precision Workstation 670.
The problem is that WRITE SPEED on this drive CANNOT EXCEED 50 MB (benchmarked with ATTO). I've been trying different setups; on Win XP Pro x64, Win 7x64, different controllers (on-board CERC and Adaptec 1430SA), using manually adjusted partitions (XP x64), running Intel SSD Toolbox, proceeding recommended optimalisations and NOTHING HELPS.
Bandwidth seems to be cut on certain level, see the atto results.
Read speed is, let's say, satisfying: ~200 MB/s (on 1430SA).
Magic 50 MB/s is not to overleap. If you have experienced similar problem and found the solution please share.
Solved! Go to Solution.

OK. Thank you.
So I'm disappointed a little bit.
The 40GB is not a speed demon as written on attached sticker...

Yup, the numbers are normal. The 40GB model have half the NAND chips and half the channels so write performance is impacted. However, I would not worry about it too much.
Basically, your disk usage breaks down into (order of importance):
Random reads - fine here since read performance is good
Random writes - fine here since small file write performance is good
Sequential read - fine here since read performance is good
Sequential writes - not very important since how often are you writing 100MB+ files to a 40GB SSD?
