    By the way, nothing in either link about AHCI.

    I've used both interchangeably, depending on what was linked on the Tweakguides website. there should be no difference really. All Intel and 3rd party Intel based boards should have the exact same hardware with regards to SATA, USB etc.

    So that link, either yours or mine, that says nothing about AHCI is what I would use to update the AHCI driver? And all that needs to be done is run it after OS installation?

    No. I didn't say anything about updating an AHCI driver. Win 7 supports it natively, you don't need an AHCI driver.

    But, if I want to update the AHCI driver to one from Intel, what then?

    Sorry for the delay in resopnding, I was waiting until my X25-M arrived to answer.

    I recommended installing the Intel chipset drivers purely because sometimes people forget to install them when running AHCI. The chipset drivers also contain USB drivers etc that still need to be installed.

    To use the latest Intel AHCI drivers, you do indeed need to install the Intel Matrix Storage Manager. The AHCI driver included with Windows 7 is also an Intel written driver, but is a little older. Performance is good, but the latest AHCI driver is a tad faster, and definitely worth using.

    I must also correct my comment in my earlier post where I stated 37.3MB/s for random 4K writes to be slow. This is actually phenomenally fast. For example, an OCZ Vertex, which has double the sequential write speed of the X25-M only has a random 4K write of about 8MB, which is a hell of a performance gap. This means that for usage involving alot of sequential writes (video encoding etc) the Vertex is probably the better choice. For an OS and Programs/Games drive though, IMO the X25-M is a much better drive (which is why I bought one).

    Note that I do recommend you move the following to your mechanical drive to maintain the performance of the SSD via avoiding unnecessary write operations:

    • Page file
    • Temporary Internet files (cache)
    • Windows temp folders (alter the environment variables)


    Also I've disabled search indexing, as the drive is fast enough not to need it. Same goes for Superfetch. As the drive never needs to be defragmented (any normal disk defrag program won't actually defrag a SSD due to the way data is stored) disable scheduled defragmentation. You want to avoid all unnecessary writes to your SSD, especially ones using very small amounts of data. Se here for why: AnandTech: The SSD Anthology: Understanding SSDs and New Drives from OCZ

    The most important thing to do, if you haven't already, is to update the Intel drive to the latest firmware. This is VITAL. There were problems in all firmwares up to the latest version which could cause severe slow down on write operations (due to the nature of MLC flash). The new firmware prevents such slowdowns on new drives and also fixes the problem (after performing a long sequential write eg full format) on "used" drives that have "degraded". In short, the garbage collection algorithm has been fixed.

    You can get the latest firmware here: *Intel® SATA SSD Firmware Update Tool It's a universal tool that flashes both G1 and G2 drive versions (not sure what you have, G1 are black drives)

    Note that for the flash to be successful the CD-ROM drive used to boot to the flash program MUST be on the same controller as the SSD, and the SSD must be in AHCI, non native mode. Also the CD-ROM (according to intel) should be no more than two channels away from the SSD for some reason. This means if the SSD is on SATA_0, the CD-ROM should be on either SATA_1 or SATA_2. This is definitely the case as I did have my DVD drive on the JMicron, and the flash just hung. Re-tried twice until moving the drive to SATA_1 (SSD on SATA_0) when the flash completed in seconds.

    The following are screenshots of AS SSD:

    Stock AHCI drivers inc. with Win 7:



    Updated via Matrix Manager:



    Also running in IDE rather than AHCI causes a visible performance drop. Read speeds drop to ~225MB/s random reads/writes drop too but sequential write remains the same.

    I knew about the firmware upgrade but my Intel SSD all came with latest firmware. I have generation 2 drives.

    Windows 7 makes the needed adjustments for SSD, including the defrag thing, besides offering TRIM support. The problem now is Intel has not made TRIM available for the drives, and will not make it available for Generation 1 drives, which I think is what you have.

    As for the AHCI driver, Anand said in his review:

    "There are significant limitations to TRIM at this point. The instruction only works in a supported OS (Windows 7 and some Linux builds) and only with supported drivers. Under Windows 7 that means you have to use a Microsoft made IDE or AHCI driver (you can't install chipset drivers from anyone else).

    Unfortunately if you’re running an Intel controller in RAID mode (whether non-member RAID or not), Windows 7 loads Intel’s Matrix Storage Manager driver, which presently does not pass the TRIM command. Intel is working on a solution to this and I'd expect that it'll get fixed after the release of Intel's 34nm TRIM firmware in Q4 of this year."

    Windows 7 doesn't disable scheduled defrag on the RC, not sure about the final RTM though. It also doesn't automatically move your page file and temp directories. Depending on usage, this may or may not benefit you to do. The only intelligent determination that My RC install has made regarding my SSD is that Readyboost is no longer needed (Via a 26MB/s 4GB pen drive), and it refuses to enable it, which is good I suppose. I can use it for storage now.

    I do indeed have a G1 drive. I chose between that and a G2 because the G1 has in some respects better performance in the areas I'm interested in. OFC the G2 is faster in other areas. The differences are likely due to cache differences. I believe my drive has 32MB of cache at 166MHz, where as G2 drives have 64MB at 133MHz. For me, fast read speeds (sequential and random) plus very fast random 4K writes were the most important. No file creation will take place on my SSD, it's strictly for OS and programs.

    For my situation and usage, TRIM would be pretty much redundant, as the drive won't get too messed up. Sure it would have been a nice thig to have there, but the latest firmware does a good job with the limited garbage collection that I'll need. TRIM may actually be more of a nuisance for some than a bonus too, as it will involve more writes to the drive when enabled, causing more wear on the drive. Again, it may be an insignificant amount of wear, or it may be a noticeable amount, SSD's haven't been around long enough to really judge.

    A neat little trick to completely optimise performance if the SSD is soley for OS/programs is to first image the drive after getting things running the way you want, then performing a secure erase with HDDErase, followed by creating an aligned partition with diskpar and restoring the working OS image (a file-by file backup image). This effectively makes the OS "install" a much healthier virtually continuous group of writes. When doing a regular install many many temp files and small files are created when forming the registry for the first time etc, etc. This eliminates the small performance drop from the off.

    My performance trace in HDTach is now a constant 245MB/S compared with the picture below, before the secure erase, align, restore process. this has made a noticeable difference to performance for me.

    How are you liking the drive over all? Have you tried the Win 7 RC on it yet or are you still going to wait for your retail copy? One thig I can say about mine is that 80GB doesn't seem to go as far as I'd hoped. I only have 48GB out of 74.4GB (formatted) space left. I do believe that the RTM version of Win 7 is some 500-800MB smaller though due to the removal of debugging info and test reporting components.

    I am waiting for my pre-ordered Windows 7 to arrive. I now have 2 160GB Intel X25-M and 1 80GB Intel X25-M all G2. Windows 7 will automatically not defrag an SSD.
