srgody Posted December 4, 2009 Share Posted December 4, 2009 I recently tested the x64 SSD I have with ATTO and Crystal. The results appear to be a little slow compared to all the others I have seen. I use the drive as my OS boot. I dont know why it is slow, new Mobo and Cpu installed at the same time as drive, with windows 7. Any ideas would be appreciated Details Below ATTO Read 180 MB/s Average Write 75 MB/s Average -------------------------------------------------- CrystalDiskMark 2.2 © 2007-2008 hiyohiyo Crystal Dew World : http://crystalmark.info/ -------------------------------------------------- Sequential Read : 132.229 MB/s Sequential Write : 30.913 MB/s Random Read 512KB : 138.130 MB/s Random Write 512KB : 18.818 MB/s Random Read 4KB : 31.685 MB/s Random Write 4KB : 2.503 MB/s Test Size : 100 MB Date : 2009/12/04 17:36:45 Many thanks to anyone who reads and can provide an opinion.

aschb Posted December 4, 2009 Share Posted December 4, 2009 Have my X256 running in production since 3 weeks. All data on X256. Currently 81 GB used (from 256 GB on drive) CrystalDiskmark 2.2 shows (5x 100 MB) r 203 w 196 r 174 w 156 r 25.5 w 8.51 Link to comment Share on other sites More sharing options...
srgody Posted December 4, 2009 Author Share Posted December 4, 2009 It would appear that I have a slow one, I have done all of the windows 7 optimizations suggested in previous threads and still it is slow as. Has anyone got any suggestions as to speeding this up or have I just got myself a slow drive, I bought the X series because I thought it would be the fastest. Any suggestions please?

Corsair Employees RAM GUY Posted December 4, 2009 Corsair Employees Share Posted December 4, 2009 I would try and image the drive to another drive then down load and run Parted magic under system tools select erase disk and wipe the drive with the secure erase and then when you format the drive use 32K Clusters and test the drive with no O.S. on it to be sure its running at close to the tested spec. 220 MB/s sequential read and 135 MB/s sequential write.

srgody Posted December 4, 2009 Author Share Posted December 4, 2009 I will give that a try. Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 4, 2009 Corsair Employees Share Posted December 4, 2009 NP Please let us know what happens and by the way what controller are you using for the SSD? If its not an S-ATA II controller the performance will be lower. Link to comment Share on other sites More sharing options...
srgody Posted December 4, 2009 Author Share Posted December 4, 2009 SATA II Controller is Intel P55, also tried Gigabyte SATA 2. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 4, 2009 Corsair Employees Share Posted December 4, 2009 I have not tried that specific MB but I have heard of some users reporting performance issue with the Intel P55 chipset which I suspect it may be a BIOS/Driver issue as this platform is still quite new. So it may take some time for the BIOS and drivers to mature a bit before the issue's are resolved. Link to comment Share on other sites More sharing options...
srgody Posted December 4, 2009 Author Share Posted December 4, 2009 I have updated Mobo to latest Bios, I have attached the result. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 5, 2009 Corsair Employees Share Posted December 5, 2009 Did you try what I suggest about wiping the drive? Also can you move that to another system as a second drive just to test the performance? And what did you set the allocation size to in the format and you selected quick format right?

aschb Posted December 5, 2009 Share Posted December 5, 2009 I have my x256 running on AHCI1.0 since a fews days. Performance seems to have improved. Link to comment Share on other sites More sharing options...
srgody Posted December 6, 2009 Author Share Posted December 6, 2009 I did all that was requested, wiped, formated quickly in 32k, tested empty, then tested with OS put back on. Tested in another machine, same performance as before. Find attached document of performance test. Looks like I got myself a slow one. Link to comment Share on other sites More sharing options...
aschb Posted December 6, 2009 Share Posted December 6, 2009 Few days ago (x256): Currently 81 GB used (from 256 GB on drive) CrystalDiskmark 2.2 shows (5x 100 MB) r 203 w 196 r 174 w 156 r 25.5 w 8.51 Today: r 240 w 150 r 170 w 135 r 19.9 w 16.4 Don't know why such huge changes.

srgody Posted December 6, 2009 Author Share Posted December 6, 2009 Tested again this morning, Sequential Read : 125.653 MB/s Sequential Write : 34.549 MB/s Random Read 512KB : 132.006 MB/s Random Write 512KB : 20.790 MB/s Random Read 4KB : 22.919 MB/s Random Write 4KB : 2.781 MB/s It makes me wonder why I spent the extra cash on the X series, when the P or M series would have given me simular results.
