    Im coming from a windows pc with a SSD that produces 250mb/s and just bought a macbook pro. I'm deciding on a new drive - I need extra space but down want to spend $500 to get it. Since my current SSD isn't BLAZING fast, would I notice that much difference with a momentus?

    Here's a CNET review of that drive. It only has 8 gigs of flash ram.!

    I looked at this when I upgraded my 08 MBP but passed for a Western Digital Scorpio Black and a 128 gig SSD.

    I've got the older 1st Gen 500 GB Momentus XT humming away quite nicely in my 2006 Core Duo MacBook. The paltry 8 GB of Flash is a significant weakpoint of the Momentus XT, and that Flash memory is used by the drive as a read cache; all writes go directly to the hard drive. On the upside it is a 7200 rpm drive, with a healthy 32 MB cache.

    In terms of price/performance, it normally doesn't beat out the combo of a decent large hard drive and an SSD, but it is worth looking into if it's on sale; I got mine when one of my local dealers had a $50 off sale; leaving it costing about as much as an equivalent 8 MB 5400 rpm drive.
