    I'm wondering if TRIM on Windows 7 is limited to a SATA connection or will it work on a PATA connection also? I'm looking to upgrade my viliv s5 to a new ZIF PATA SSD and this question has been nagging me for a while. If this seems like a stupid question, please don't giggle. I don't know too much about SSD's and even less about TRIM or SSD routine maintenance, but I'm learning!

    A PATA controller would not understand the TRIM command, nor forward such command to the hard drive. I would be highly surprised if you found a controller that did support TRIM.

    I think Windows 7 TRIM is a function of AHCI, which is for SATA drives only. However, I believe you can manually TRIM your SSD.

    Don't feel silly because I'm still learning about SSD. It's a new technology that definitely has some mystery and its caveats.

    Thanks guys! What is this "manual TRIM" you speak of?

    Thanks Sean! That's some good reading material. Also, it seems all I see about SSD's these days is the serious performance hits once every block on the drive has been read/written to at least once. How much of a performance hit are we talking? Say my initial read speeds were 80mb/s (remember ZIF PATA), then what kind of speed would I be seeing after say a month?

    My PATA Runcore ProIV ZIF SSD can accept trim commands via wiper.exe. Trim is part of the ATA7/ATA8 command set. I've also read that trim requires Makes sense then why Indilinx SSDs need to be running in IDE compatility mode for wiper.exe to work.

    Ok, new development (for me)! So does wiper.exe affect the performance of an already bottlenecked connection? And how does it stack up to the quote/unquote real TRIM?

    I get real trim from the ProIV (Indilinx) using firmware 1916 and win7. Haven't noticed any performance degradation. Only need to run wiper.exe (manual trim) if using XP.

    Page 9 and 10 of Anandtech's SSD Relapse ( http://www.anandtech.com/storage/showdoc.aspx?i=3631&p=9)cover some details for various drives. Note that the actual loss is very dependent on the specific model. In fact, you'll probably want to read the whole article, a lot of good information in there in general ( http://www.anandtech.com/storage/showdoc.aspx?i=3631).
