    Thanks guys

    So sanity check:

    Get a pair of DL 120 G7 with a single SATA Samsung 830 SSD each with a 3.5 adaptor and a HP 3.5 inch adaptor...Not use the in built RAID, TRIM should work on Windows 2008 r2..but risk HP firmware rejecting the drive


    Get a pair of DL 120 G7 with a single Revodrive 3 x2 PCIe SSD each, Not use the in built RAID, TRIM should work on Windows 2008 r2..but need to find out whether it will fit the PCIe slot and any BIOS settings needed for intel Xeon specifically for it to boot up from the PCIe slot

    Sounds about right although I haven't tried a boot from the PCI card before so you are on your own with that one

    Just in case anyone is wondering about life time in a server please do the maths on the hours on and how many months that represents with 0 flash blocks reallocated -

    Thats running our Lync, Exchange, UAG and RDS Load Balancer server

    ah, got it, so the Revo is not used as a boot drive, and you use standard HP brand HDDs in your DL165 for booting to OS?

    In which case might try the Samsung options first, worst comes to worst I could test the Sammy SSD first in a ML110 G7 i have, as far as I know very similar Hardware wise to the DL120....then buy the rack server later, sounds like a safer bet...PS also heard you can under provision the SSD to extend its life.

    SSD's aren't my strong point but I've just done a quick bit of googling about the trim support as I know when I have looked into it in the past, LSI/3ware Raid controllers don't currently support trim commands and I think it's the same with the HP/Dell controllers.

    The Revodrive3 apparantly appears as a storport device under windows7 (going to be same in Windows 2008 R2 I'm guessing) and apparently Trim commands won't be sent. I'm thinking that if you switch to Server 2012 the support for trim commands will be there for the Revodrive3 as Microsoft will support this under Windows 8.

    So essentially I reckon you will have to rely on the drives internal garbage collection if using any SSD's that are in raid when not connected directly as a single disk.

    Otherwise, single SSD on internal controller and depending on the chipset you should get trim support unless you go with the Revo and go for Server 2012.

    If I'm wrong please correct me (someone/anyone!)

    Yep not booting direct off the drive - we do however have plenty of VMs booting off that drive which in theory would put more strain on the drive than a single RDS server.
    @VeryPC_Ed - quite right about there being no TRIM under Windows 7 however over 9 months in now and 0 reallocated flash blocks...think that speaks for its self that the need for TRIM might be disappearing (at least in the relatively low usage environments you will find in a school (compared to a corp datacentre)).

    Hey James, thanks for the reply, out of curiosity do you have your SSD's over provisioned ?

    I think there's a lot of FUD about SSD's and people usually look at the extreme's (which they never end up experiencing), totally agree that under everyday operating conditions a decent consumer SSD will more than likely do fine, if it's in a DC then that extra spend for additional corp/ent features (like on Intel 320 (now EOL) with the power loss protection) can easily be justified if the workload requires it.

    Edit: 320 not 520

    Thanks again everyone

    Bit of googling and found some comments about DL120 G7s with 256gb Samsungs 256gb SSD installed and working,so quite encouraging:

    No overprovisioning on the drive (at least no more than the standard for the card) - if you boot into the cards bios/firmware you can enable a extended life mode which cuts down on your useable space but I don't see much of a need for it at this stage.

    This is quite encouraging too.



    Based on how much data James has written to his RevoDrive, I don't think you have much to worry about.

    By the way, should you ever decide to overprovision the drive, don't bother reducing capacity beyond 27%...
