    Hi

    may i ask you a question?

    after several image restores did you find a lost of performances of your solid state disk?


    does somebody do a benchmark before and after an image restore?

    i would appreciate your answers

    thanks

    Not any more than other writes of the same amount. As in negligible, unless your SSD is old and faulty, or the imaging program isn't configured properly for it.

    It usually has to do with alignment and migration from HDD, but up-to-date imaging programs should support SSD's fine by default.

    Did several restores on two machines with an SSD each so I can say no noticeable degradation of performance. And alignment was right each time.

    Hi Mantra! You didn't merntion your running OS or any system info so I'm shooting in the dark here.

    If you're running XP (or VISTA, I believe), you will have degradation eventually... it does not support TRIM which is required for proper SSD internal management.

    If running W7...

    YES (eventually) if TRIM is not turned on (same as XP). YES if running RollbackRX (does not support TRIM properly on its selected protection area). Yes if restored partition alignment is not on a 2048K byte alignment (can be set in IFW).

    hi RollbackFrog i'm running w7 sp1 64bit
    i don't know what is it Trim :(
    i use always IFW , and the partition on the ssd was created by w7 sp1 64 legit installation dvd

    image for linux has 2048k disabled for default

    Recently restored my Win7.. no slowdowns or performance issues, prior to restoration I issued internal erase method and clonezilla restored without a problem.

    2 partitions on the ssd 1 for windows and 1 for games both were encrypted with truecrypt (and still are)

    i restore at least once a week.
    sometimes a lot more.
    especially when i was distro hopping.
    then it could easily be 10-20 times per week back then.

    since last November when i bought my SSD, i must've restored a hew hundreds times.

    everything is good so far.

    To which I replied earlier that I've done many restores on two machines with SSDs (one with Win7 and one with Win8 ).

    "Trim" is a Windows 7 (and above) function that tells your SSD that a particular disk block is no longer in use. This is needed information by the SSD for proper Nand CELL management and to eliminate long term wear on the Nand Cells which eventually causes the SSD to slow down during its access phase.

    If you run WPI (the Windows Performance Index), it will discover your SSD and make sure that the "Trim" function is set to ON.

    The "Align Partitions on 2048 Sectors" function should be ENABLED when restoring an IF(W/L/D) image onto an SSD.

    That was my first restore so far. Sorry for the misunderstanding.

    P.S. I don't plan on restoring my win7 install soon either, only did restore it because I needed to test linux gaming on my machine.

    mantra,

    Is this a theoretical question or have you noticed a performance issue?

    It is not theoretical and does not have to do with the number of restores.
    Let's say that you have taken an image of the OS that occupied 16 gb on an ssd of 80gb.
    Then during the use you "fill" it with lots of files videos, mp3s, etc. until it's almost full.
    After that you decide that you want to restore the image. After the restore the disk will again have 64gb of free space but since a trim command was not run (no file was deleted before the restore) you will have a performance degradation during writes unless you issue a trim command to the free space of the system.

    and here comes handy a tool like free space trimmer.

    When I ran dual SSDs on my laptop in RAID 0 there was no loss of performance after restoring an image. Since there was also no TRIM support for RAID it didn't even figure into it. Based on my experience I would say that if you do have a performance loss then something went wrong.

    Sorry Mantra... my bad. it's called the "Windows Experience Index." You access it in the following manner...

    1. <right-click> your COMPUTER icon and select "Properties." You SYSTEM window will open.
    2. <click> "Windows Experience Index" in the center of the window. "The Performance Information and Tools" window will open.

    3. In the lower right hand corner, <click> "Re-run the assessment." This will test everything once again (it will take a while... be patient) and set the system up properly for the use of your SSD. When the assessment is complete, your PRIMARY HARD DISK TRANSFER RATE should be at least 7.1... if it's not, you have a real problem with that SSD.

    And you should take Panagiotis' suggestion and run the "Free Space Trimmer" after you run the above WPI and after each system restore, regardless of which imaging program you use. If you do this, and your SSD has not already degraded, it should keep it in good working order for the life of the disk.

    Without the use of the Windows "Trim" function, regardless of your SSD configuration, the wear leveling of those devices will start to affect your disk access in due time, significantly shortening the life of those SSDs. The RAID configuration itself will of course help your access time, but in the long run the SSD access time will degrade quicker than normal.

    One or two restores won't affect anything, it's the number of SSD WRITE operations over a given time period (lots of system file write operations... lots of full disk restores, etc.) that will most affect your drive performance.

    Windows 7/8 have a Trim function if you run the Disk Defragmenter.

    the OS knows it's a SSD so instead of defragging like a regular drive it runs Trim.
