    Default Performance degradation, refresh tool?

    Hi,

    I've heard that performance of these SSD drives suffers degradation over time and that there would be a tool to fix that. Could you please point me to this tool for the runcore SSDs?

    Cheers,
    M

    ahh, i think he wants an XP version of Trim, or Wipe, one that rewrites all the pages left by a file delete...

    Doing a full format on a SSD will have the oposite effect. It will "dirty" up the flash blocks thus slowing the drive.

    Do a search for "Wiper.exe". The latest version is 0525 dated 5th December 2009. Run it and in a minute or so your drive will be TRIMmed. Wiper is extremely slow if using AHCI so set the BIOS to Legacy IDE. There's no performance penalty unless you use hot swapping.

    Alternatively to completely restore 100% of factory fresh performance use a utility like HDDErase or Secure erase, set to a single pass. These programs issue the "ATA_SECURE_ERASE" command, flagging all blocks as ready to use/clean. Ths process is destructive so you need to backup your data first. To prevent the need to re-install everything use an imaging program such as Acronis True Image then simply restore the drive after. Acronis will restore the drive to a bootable state with everything present and usable including all your programs. It writes in one continuous chunk, so it won't eat as many fresh flash blocks as a Windows install does (by using temp files, constructing the registry etc).

    HDDerase can be run from a bootable floppy/USB stick. Secure Erase needs to be run in a 32Bit Windows environment. a 64bit version will not work. If you have Windows 64bit installed you can download a Windows recovery CD containing the recovery console (32 bit version). Recovery Console is classed as a Windows Environment as far as SE is concerned.

    After the erase, if not imaging (ie you're doing a fresh install) you must choose to Quick Format the drive. when using Vista/7 it will Quick Format by default. XP will ask you.

    I'm not familiar with that program so I can't give you an answer unfortunately. If it issues the ATA secure erase command then probably, yes. If it simply deletes partition info AKA "diskpart clean" command then no.

    I don't own a Mac so don't really know the limitations if any on running external programs. Are you able to boot from a USB stick to DOS with a Mac now that they're basically PC's/Laptops with a different OS? I don't know if the Mac BIOS would restrict you. If not, running any of the utilities mentioned would be fine, either HDDErase or GParted (from here Browse GParted Files on SourceForge.net ). Alternatively you may have to hook the SSD up to a PC and use one of these tools if possible.

    Wiper.exe worked a treat for me and I just run it periodically to keep things running sweet.
    If you are running Windows I recommend it (unless you are using Windows 7 which I understand has the feature built in).
    Just unzip and run it.
    There is no other interaction with the program. It just runs and then closes.
    Simplicity itself.
    See how it performed for me at this thread:

    Wiper.exe is attached to post #7.

    I agree that (as for me) wiper has been an excellent tool. However I believe it requires a windows environment to run. Unless the OP is using BootCamp, he may not be able to use it.

    My results from using wiper (I'm compiling info for a brief SSD guide) is that it does indeed effectively restore performance to around 94-95% of a clean fresh drive. This to me is more than enough for me to only use HDDerase on my Intel X25-M. A HDDErase/SE of the same Indilinx drive does yield a 100% performance increase (until all flash blocks are used again).

    One interesting thing from my use of a OCZ 64Gb drive (lent by my uncle, he's a network admin and systems builder full time) using Garbage Collection 1.41 FW is that over the course of a week, drive performance can reach over 100% of "cleaned" condition. This is probably down to natural variation in benches though so I assume it to be 100%. GC in this form does shorten life of the drive. All SSD's use GC but in a gentle manner. The 1.41 has it souped up to become the primary means of keeping the drive clean. Usual best practice is to combine light GC with TRIM.

    We will see better and better FW's released as Indilinx receive feedback and complete their tests etc. Some responsibility also is put upon MS. Many inc Indilinx believe that Win 7 TRIM is flawed in some minor way. Perhaps this update to TRIM will appear in Win 7 SP1 or hopefully sooner.

    Yeah... I just threw that in there as the OP doesn't actually say anything about what machine or operating system he's running (which I would think anyone seeking such technical advice ought to include as a matter of course).
    That coupled with the fact that Windows is far and away the most common OS I thought I might hit the barn door even with a blindfold on

    The attachment on that thread could also save others hunting around (too much) for wiper as I had to.
    Runcore did respond to that thread indicating that they would maybe make it available themselves................

    I agree that the OP didn't release details, which as you rightly point out is a faux par with regards to anyone being able to help. Ultratux though did state that he's running OSX, so he is definitely a Mac user.

    I'm not 100% sure if it's impossible to use on a Mac though. I bought "Plants VS Zombies" the other day and that happily runs on Mac with what look to be the same binaries (could be wrong).

    As you know with Runcore, they aren't the brightest button in the sewing box. I bet my last 5 they won't bother puting it up for download. They can't even reply swiftly to customer queeries on the forum, which is sad.

    I had trouble getting hold of the correct wiper version too. Finally tracked down the latest build that is now apparently "80%" safe to run on 64bit Windows vista/7/XP.

    IMO Runcore need to get their finger out with regards to customer service. I feel for those with problems who bought one of their devices. Thankfully their products aren't widely available through the major retailers (Scan, Dabs, OCUK Overclock etc) or I may have been tempted to buy one, and be left in the dark RE support.

    An alternative to wiper (if an OSX version exists) would be Diskeeper's latest version which includes SSD optimisation that actually works. Both my X25 and Indilinx based Corsair respond well to it. In combo with wiper I get the same result as wiper alone but as free space is consolidated I also get the max time before flash blocks become dirty again.
