    Finally, look man as soon as you install win7, your ssd will automatically defrag itself with the trim command.
    dbee has a Generation 1 X25-M. G1 drives do NOT support TRIM, and according to Intel, never will. G2 drives however do have full trim support. From Anandtech:
    The new drives come with TRIM support, albeit not out of the box. Sometime in Q4 of this year, Intel will offer a downloadable firmware that enables TRIM on only the 34nm drives. TRIM on these drives will perform much like TRIM does on the OCZ drives using Indilinx' manual TRIM tool - in other words, restoring performance to almost new.
    The difference between new and used condition is also greater on G1 drives than G2. Random write performance can drop by as much as 35% after a single complete fill of the drive, or after the controller has no more completely clean flash blocks and has to conduct a Read > Modify in controller cache > Erase > Write. Note that by "controller cache" I mean the 256K of on die cache on the controller package. The 16MB DRAM cache never gets filled with user data, and is actually involved in calculations and processes to do with deciding where to write, ie wear leveling etc.



    In certain scenarios, even with the latest Intel firmware, the drive (both G1 and G2) can experience severe performance degradation. Admittedly you'd have to either have some real strange usage pattern or be addicted to running IOMeter, but it is reproducible. After dropping to below 50MB/s for sequential writes, the drive tends to spiral. Continually sequentially writing to the drive (to activate the firmwares garbage collection) seem to help, but not enough to turn performance around. A secure erase (~3 minutes work, plus ~10 min to re-image) completely restores performance.

    I'm not saying everyone should go to such lengths. I also agree that write amplification and internal fragmentation don't impact performance on Intel drives as much as others. This is due to the fact that for instance random 4K writes for intel drives are~5x + faster than on Indilinx drives in the first place. My point is, if you paid for a drive that can do 40+MB/s random 4k, then why just sit back and accept it when it drops to ~26MB/s (G1 drive)?

    Your statement "You won't notice a difference" depends on usage patterns. Maybe for a standard desktop system you won't notice. For server applications like an app or media server, you certainly will notice it. These applications are all about random IOPS.

    At the end of the day, what is easier? To Perform a secure erase (3 minutes) and restore a complete backup image of OS and drivers, plus basic programs (~10 min) or to just format and re-install, creating a sh1t load of random writes (OS install creates the registry etc, although several large files, each incremental write to them is , to the SSD, the same as any other split write operation). The re-install will take you ~25-35 min for the OS, plus (guess) a hour to install updates, drivers and basic programs.

    I fail to see where this "effort" and "time" of which you speak is being wasted.

    Imaging the drive will prolong the amount of time before no more free blocks are available. Sure, for a power user it still may not last long before all blocks have been filled once, but for a light user it will. Yes, all programs will write to disk. You can see this by enabling the I/O write bytes column in Task Manager. For example, Chrome has racked up over 78 MILLION bytes written in around 3 hours of surfing etc. However, as I took a little time to create a RAM drive and stuck the cache and user data there, most of those writes are to RAM and not my SSD.

    The issue of MLC flash wearing out does come in to the whole idea of minimising writes. I don't really worry about that though. I'll have replaced the drive with a G3/G4 device with at least SATA3 by the time anything comes close to wearing out. But best practice would still be to limit writes as much as possible.

    Then there is now a firmware update available for your drive. Updating to 02HA gives TRIM natively in Windows 7 and via a runnable program in Vista and XP. Download here: *Intel® SATA SSD Firmware Update Tool

    I'd still use imaging software though. If nothing else, it beats having to take 4 hours + to re-install the OS and all your programs.

    Intel Launches TRIM Firmware For 34nm SSDs - Final Thoughts and Conclusions - Legit Reviews

    yea i posted a thread on that. I was under the impression it would be constantly running TRIM within the backround, this is even better putting it on a schedule.

    Psycho, im gonna PM you a little later on about another issue on my bro's machine. you can see some info on it here...

    If you're running Windows 7 with the Microsoft AHCI driver, then TRIM will be automatic. If you're using the Intel driver, or running Vista/XP then you need to manually run the tool or schedule it.

    Wow when running the TRIM function manually, it completes in about a 1-2 seconds.

    It will complete quicker or slower depending on how used your drive is. If you've for instance just done a secure erase and re-image and run the tool, there will be little if anything for the TRIM tool to TRIM.

    Ironically, the G2 drive will benefit least from TRIM too. On your drive, Random IOPS are lower at "new" than mine (~42MB/s random 4k write compared to ~35MB/s on a G2), but the G" maintains that speed much better than a G1 can. Best to use it after a big file delete or program/game uninstall, as well as have it scheduled for once a week, with a good time range in case your PC isn't on.

    I'm planning on getting another drive (also G1 if I can find it) to use RAID0 for better sequential write and more space mainly. TRIM will be useless in that configuration as it can't be run on a drive that's a member of an array.

    Have you got your copy of Win 7 installed yet? If so you can forget the TRIM tool, it's all automatic.

    Getting your install going, followed by an image will mean no more waiting for Windoze to install again, ever.
