Rick, wanted to 'check' with Corsair to see if they'd 'enlighten' me on how Trim works. Opened a question in their forum, --> http://forum.corsair.com/v3/sh.....p?t=115816. We'll see what they say?
They DO have a LINK for TRIM ==> http://forum.corsair.com/v3/showthread.php?t=84677, it is a FAQ... interesting stuff...
From it :
How does TRIM work?
TRIM actively deletes invalid data from the SSD’s memory cells to ensure that write operations perform consistently at full speed. Invalid data is defined as data that has been deleted by the user/host OS, but which remains physically stored on the memory cell until it is overwritten. Since a memory block must be erased before it can be re-programmed, TRIM improves performance by pro-actively erasing data blocks containing invalid data, thereby allowing the SSD to write new data to the memory without first having to perform a time-consuming erase command.
Now reading that, the program shouldn't work if I understand it correctly. The file it writes need to be read, trimcheck-cont.json. However, unless it was deleted, TRIM wouldn't do anything according to the above? At least that is what I think it does? However it cllaims it works like this :
The program will set up a test by creating and deleting a file with unique contents, then (on the second run) checks if the data is still accessible at the file's previous location.
Hmm, that file is always there though, maybe it does it with something else?
Hmm, just ran it again, got a DIFFERENT answer, *INDETERMINATE*? It said maybe another program wrote data there?
Oh, another point for you on the TRIM FAQ page,
How do I enable support for TRIM?
For TRIM to function the operating system, storage drivers and solid-state drive must all support the TRIM command. Currently, only Microsoft Windows 7 operating systems support the TRIM command and only when the default Microsoft Storage Driver (MSAHCI) from Microsoft is used.
As such, TRIM is only supported in single-drive configurations, since current RAID storage drivers do not pass on the TRIM command from the operating system.
Is it due to the flash on older SSD's that it doesn't work on RAID? Don't know the date of the FAQ though?
