Does Windows 2008 Storage Server support the TRIM command?

    Question

  • Hi,
    Not sure if this is the right forum but here it goes:
    I've been unable to find out if Windows 2008 Storage server supports the TRIM command used for SSD's. (I know Windows 7 and 2008 R2 have support for it)

    Is there somebody on the Technet forums who has the definitive answer..?
    TIA!

    Windows Storage Server 2008 does not support TRIM command

    Correction on Windows Server 2008 R2 - and for that matter Windows 7 as well. Both of these support TRIM command but ONLY for ATA drives. The SCSI (T10?) committe is still busy finalizing the equivalent command for SCSI drives

    If your SSD drives are not presented using ATA/SATA interface, you are out of luck for the TRIM command

  • Thanks Dilip for your help..!
    So in short the answer now is NO for Storage server, YES for W2K8 R2 and Windows 7 if the SSD drive is presented through ATA/SATA interface..

    Any chance this will change in the future with a servicepack..?
