Yes, that's the case. Logically, your 6GB partition is along a fixed sector boundary. Any OS-level reads/writes will be to those sectors. However, the SSD controller maintains its own mapping table, and will re-map writes to those sectors to potentially any page/block on the drive based on previous writes. The aim of the controller is to keep every block on the SSD with an equal number of program/erase (P/E) cycles--the intention, of course, to prevent any given block from wearing out before the others. The net result is that writes in XP w/o TRIM could degrade the performance of any and every page/block on the SSD.

Greg, Unfortunately, The X41 Thinkpad Tablet uses an strange oddball 1.8 inch drive that is a SATA drive but with a PATA front end... yeah I know.... and the only one available is made by a Chinese company called KingsSpec...so there is no utility. It breaks down to I am surprised I don't see the usual 100MB hidden parititon in win7 C Win7 = 52.62 D XP = 6.34 I used Paragon to partition it in such a way that the XP partition was created and first installed in a primary partition that was at the bottom 6GB of the drive... so to speak... leaving free space in front of the XP partition. When I installed win7 there was 52 GB of free space in front of the XP partition. Even after install there is 25GB of unused space in the Win7 partition. Are you saying that even though I set it up like this and it appears like this in partitioning software, the SSD itself has data from both operating systems written and mapped randomly all over the drive and XP is not confined in a particular region of the SSD? m At 03:45 PM 8/2/2014, you wrote: >No. The TRIM command is only sent upon a triggering action--in Windows, >that's deleting a file or performing a format.
