Restoring vertex performance?

post #1 of 2
Thread Starter 
Hey guys, so currently im having performance issues with my vertex 60gb in raid. My plan is to break up my vertex raid array and put the two drives in to two different computers and un-raid them so i could enable trim.

My question is what would be the best process (reformat?) to restoring the performance back to 230mbs read /70mbs write speeds?

Currently my raid performance between the two have dropped alot from the ~400mb/s read ~140 write they had when i first had them.

Thanks!

I recommend doing 2 things:


  1. Disconnect all other drives (but leave any optical disc drives connected) for the sake of avoiding having the boot sector placed on a drive other than the one you're installing Windows to.
  2. Boot from the Windows 7 installation DVD
  3. When you see the "Install now" button, click "Repair your computer" (screenshot)
  4. You'll see a little window named "System Recovery Options" appear that searches for Windows installations.
  5. When it finishes, you will see a dialog box. Select "Use recovery tools that can help fix problems starting Windows. Select an operating system to repair.", and then click Next.
  6. Click "Command Prompt"
  7. Type diskpart into the command prompt and press Enter to load DiskPart
  8. Type list disk and press Enter
  9. Type select disk 0 (or whichever number your SSD has been assigned) and press Enter
  10. If you want to be sure you have the right one selected, then type list partition and press Enter.
  11. If you know you have the right drive selected, then type clean and press Enter.
  12. Type create partition primary align=1024 and press Enter
  13. Type format quick fs=ntfs and press Enter
  14. It will appear like it's going to take forever, but then it suddenly finishes about 5-10 seconds later (it jumps straight to 100%).
  15. Type active and press Enter
  16. If you want to see your creation, then type list partition and press Enter.
  17. Type exit and press Enter
  18. Type exit and press Enter
  19. Click Restart
  20. Boot from the DVD again and perform a normal installation using the "Custom (advanced)" type of installation.
  21. Do not tell the installer to format. Just select your drive and click Next.

So to summarize:
  1. Disconnect all drives except for the drive you're installing Windows to
  2. Boot from the Windows installation disc
  3. Click "Repair your computer"
  4. Select "Use recovery tools that can help fix problems starting Windows. Select an operating system to repair."
  5. Click Next
  6. Click Command Prompt
  7. Type diskpart into the command prompt
  8. Type list disk
  9. Type select disk 0 (or whichever number it turns out to be)
  10. Type clean
  11. Type create partition primary align=1024
  12. Type format quick fs=ntfs
  13. Type active
  14. Type exit
  15. Type exit
  16. Click Restart
  17. Install Windows 7 without telling the installer to format


That should not only restore performance, but aligning it to 1024 KB helps get the most out of the solid state drive.
