I was planning on swapping the new iMac's HD with a 500GB Samsung 840 SSD (note: not the 840 Pro), but until some brave soul figures out how to get the display back on the case, I've decided against cracking open the iMac. So I decided to slip the SSD inside a Buffalo Ministation Thunderbolt enclosure and set up as a DIY Fusion. I'm not sure if I'll keep this configuration, but at this point I'm leaning towards it, although I'm not sure if the larger SSD size really is much of a benefit compared to 128GB. Anyway, I've barely started using the machine in this configuration, but I figured I'd post the BlackMagic throughput numbers for the DIY Fusion Drive. If there's any other free disk test utilities anyone wants to see results for, I can try to check them tomorrowjust point me to them. I'll also post some photos of opening the drivebasically it's just like what AnandTech had.
