Hi, I have this program, as I have a mix of 2 SSD's ( 1 60GB for Win7 & 1 256GB for FSX) and 2 normal WD 1TB hard drives for scenery, and was impressed at the fact that the program can differentiate between the drives, turn of the windows defrag for the SSD's ( I had done this already) Do the trim and also defrag the conventional drives. My question is this: I have set up the program to trim the SSD's daily but if I run the anaysis on the drives, it shows the SSD's as being heavily fragmented. Does this mean they are still fragmented or is ist simply that the way the drives work and are written to will show this? I just want to be sure that the SSD's are properly optimized and that I have it all set up correctly.Thanks, Mark

Fragmentation is a meaningless concept for SSDs: Since there is no physical read/write head that needs repositioning, the access times for a contiguous vs. a heavily fragmented file in an SSD will be identical. Any drive defragger vendor touting its defrag abilities for SSDs is selling old-fashioned snake oil.What an SSD needs is trimming, to recycle data blocks no longer in use. If you have Windows 7, this is done automatically by the operating system, and here again any defrag vendor would be selling you something you don't need. With Vista and XP you have to invoke the TRIM command maually via a support software that comes with the drive, provided the drive indeed does support the Trim command, as earlier models often do not (and some that don't do after you update the drive's firmware).Cheers,- jahman.

Hi Jahman, I realise all that, thanks all the same, O&O are not saying their program defrags SSD's, it simply differentiates between them and normal drives, ensures windows does not try and defrag them and also schedules trim function. My question was that the drives show up in the GUI as being fragmented, by approx 50%. Is this normal and if so why, as presumably, Windows and O&O are automatically running the trim function... does fragmentation on SSD's show up on analysis by a defrag tool such as this? Presumably SSD's are subject to fragmentation in the same way normal drives are, or you would not need to trim them.... I just want to know why the O&O GUI still shows them as fragmented, when the trim function should ensure they are not....cheers, mark

Mark,On an SSD trim and file fragmentation are two different things: On the SSD all files could be contiguous (again, a meaningless concept for SSDs) and then if you delete a large number of files you would need to trim the SSD to recycle the deleted data blocks.My guess is O&O Defrag is just showing that on the SSD files indeed are fragmented just as in a HDD, ecept with an SSD it doesn't matter. Turning the question around, what should the O&O Defrag User Interface show for an SSD if fragmentations is no longer something important to show? Perhaps a single very large fonted number with the percentage of blocks that need to be trimmed? The elephant in the bedroom question for O&O Defrag, is what exactly is the role of a defragger in the case of an SSD given that SSDs no longer need defragging and the OS does the trimming bit automatically? The short answer is "none". And for the HDDs we all will continue using as backups, the OS standard defrag is good enough.Cheers,- jahman.

I would disregard what O&O or any other standard defrag program was indicating as fragmentation on an SSD. Sure it is fragmented in its own right and the standard defrag programs do not recognize this as an SSD. Bottom line; do not worry about defragmentation on an SSD to a point.What is that point? When performance becomes noticeably degraded or when use of a bench mark tool like ATTO Bench, indicates degradation from baseline.I would ensure that my firmware was updated and that firmware included a garbage collector. W7 sends it own TRIM command and you do not need O&O to do that. I would only use the O&O TRIM if I was not on W7.Intel recommends a secure erase on their SSD’s whenever reinstalling data. To restore the disc not because of security.Diskeeper has a “hyperfast” add-on for SSD’s to reclaim free space. I think on a degraded disc this may have merit. http://www.diskeeper.com/hyperfast/index.aspx http://www.diskeeper.com/diskeeper/home/premier-hyperfast.aspx http://www.v3.co.uk/vnunet/software/2234895/review-diskeeper-09-pro-premier?page=1For the less savvy, don’t worry about it.http://en.wikipedia.org/wiki/Solid-state_drivehttp://www.tomshardware.com/news/diskeeper-ssd-defrag,6848.html

OK, thanks everyone, thats cleared it up for me, cheers, Mark
