    So, when I first got this Rev C, I was shooting up at 60MB/s+ of write speed very easily. Read speed also the same.

    Now after using it for about 3 months now, I'm dropped to a crap of 23MB/s of write speed and about 30MB/s of read speed.

    Anyone know a good way to recondition the SSD? My external 1TB running off of a USB gets 35MB/s and that thing's 90% full.

    I'm almost into a year of my Gen.B and it's nearly the same as when new according to X Bench. I've even been down to 3GB of free space a few times.

    My speeds are much much higher than yours. What are you doing to it? Is it like 100% full or something? I have never heard of that...

    That's a great article. Thanks for the link.
    This is the first decent article I've seen to dissuade me from using an SSD for a real-world activity like software development (which is my primary use for my Macs).

    No, It's around 60% full on the Mac side and 40% full on the Windows side partitioned as 50/50. I'm running virtual machines and software development, nothing too demanding.

    Yeah, I saw that post, but I'm not entirely sure if it'll work... I want to try a free method (if available) first.

    Furthermore, the SSD is creating latency spikes for me in Windows XP/Vista/7 while a normal hard drive is fine, even the slow 4200RPM. Right now, I feel like using a 4200 RPM as I did with my old Rev A is better than the SSD during Windows use.

    Are you running XP? That can ruin your SSD according to articles I have read in the past. It's not designed for SSD, and it can ruin an SSD's performance nearly instantly according to some I have read.

    I think your Windows is probably the problem. Definitely don't feel you could blame the Mac side. All of us with MBAs with SSDs seem well off with our SSD.

    No, I'm running Windows 7 Ultimate downloaded from MSDN. I have this problem in all 3 versions of windows. XP, Vista and 7.

    I disabled Bootcamp.exe or KBDMGR.exe and while the latency is dropped, the spikes are coming from the drive accessing files for write. The spikes are coming from the SSD no doubt.

    I don't blame the Mac's side because I don't have this problem on the mac side. Never did with any SSD, only windows running SSD gives me latency spikes.
