    Cost/Performance Compromise vs SSD; Speed Tests
    I replaced my 500GB 5400rpm WD with this Momentus XT after doing exhausting research. I use my MacBoook Pro laptop for analytical work involving large datsets. Here is why I settled on the Momentus XT vs an SSD.

    Momentus XT
    - 4GB SLC SSD integrated into the hard drive for speedy access commonly used files
    - Although not as fast as an SSD, but soooo much cheaper than 300GB+ of SSD space.
    - More vibration and a little more noise than my WD 500GB, but not significantly so.
    - Mac OS X doesn't support TRIM. I was concerned that a SSD drive would slow down significantly overtime without it.
    - Toms Hardware highly recommended it over other 7200 rpm laptop hard drives. See their review for all the techy details.

    Note that the integrated SSD is used only for reading, not for writing. It essentially clones your commonly used files on the 4GB SSD.

    If you are looking for a sweet spot between speed and space this is it. The...

    Good performance boost for the money
    I've read a lot of reviews, some good, some bad. I think some people have this idea that the product will speed everything up all the time, and this sets bad expectations. What this drive will do is cache often used data, such as core Operating System files used at boot and commonly used applications, and store that data in its 4GB SSD-like cache. If your drive already reads and writes pretty fast, in the neighborhood of 75-100MBps (megaBytes not bits), other than boot up and application loading, you aren't going to notice much of a difference.

    I use Apple's OS X Snow Leopard, and it definitely boots faster (1 minute 30 seconds prior to this disk, now 55 seconds from power on to ready + all my startup apps running), and commonly run applications also start up noticeably faster.

    I upgraded from a bit slower drive, so I see some performance gain there, but nothing huge.

    Overall I got the disk read speeds I was looking for -- faster boot, faster common...

    For certain use scenarios, it's an unbeatable cost/gig ratio
    I have the 500GB version of this drive. I also use and have used SSD's with SLC and MLC flash, JMicron controllers, Samsung Controllers, Barefoot controllers, and SandForce controllers on 32-bit and 64-bit operating systems. I've used several generations of Raptors, and 3Ware RAID controllers. I'm not saying that to brag, I'm saying it to point out I have a reasonable basis for comparison and expectation.

    Here's what the drive does well: It's alignment- and OS-agnostic, so it does not care if you run it unaligned on older XP systems. It will, over about 5 cycles, learn what you do and optimize it. You will notice your system boots much faster. It excels on systems where you boot into your OS and do the same basic tasks, say, open MS office and Firefox and Outlook.

    Here's what the drive does not do well: If you are constantly changing what you run on your computer, your drive will constantly be "learning" what you do. I have also found it does not do well...
