    Should I leave some spare space?


      I am building a new computer for work and it will have two x25M-G2 80GB drives in a RAID1 configuration. I have updated the firmware so that I will have TRIM supported, but I realize that TRIM will not (currently) work for RAID.  I am using an Asus P7P55D-E Pro and will be using Win7 64.


      I have read that it is beneficial to leave some space on the drive for longevity purposes.  My question is this: Is there any significant diference between these two scenarios?

      1.  I partition only 64GB of the drive and leave the rest unpartitioned

      2.  I make the largest partion possible (about 76GB), but never use more than about 64GB.


      And finally, do I need to (or should I) install the Intel RST Drivers?

          Yes TRIM does not work with RAID, so the best you can do is to use the whole disk (do not create a smaller partition and leave unallocated space) and try to have at least 10 GB free. Unfortunately, you will have after a while to unRAID the disks and clean them seperately to restore them to their initial performance state.


          Unfortunately, I cannot help you with the RST drivers since I haven't used them.

            You don't need to install the Intel RST drivers, but I do recommend it, because they are optimized for being used with Intel SSD's running Win7 (32/64bit).

            The currently best RST driver for me and my Intel RAID system (ICH10R with 2x160 GB Intel Postville SSD's as RAI0) is v9.5.6.1001.
