Pros: These work great for what I need them for. Whenever I need to use SATA drives in my older PCs with 32-bit PCI and no on-board SATA (or I want to add SATA ports), I grab one of these. Helps me turn some really old workstations into cheap NAS servers.

Cons: Expensive (for what I usually need them for). Often, I don't even need the RAID, just more SATA ports in legacy PCs ... but I keep buying more, so they must be worth it.

Pros: This is a must-have for sysadmins or anyone who deals with hard drives often. I used to have enclosures all over the place for reading different 2.5/3.5/5.25" devices ... now I just have these :)

Cons: The power supply for one of these stopped working all of a sudden. Also, it can be a tight squeeze using these with some CD/DVD drives

Pros: super small

Cons: super small. and they're slower than most of my other USB drives ... the 512 white one is faster ... i got a few of those too :)

Overall Review: they seem easy to lose, but i've held onto mine thus far. i keep having to hold myself back from getting more of these! they're that cool.

Pros: works as intended. don't need to keep a usb cable with you or an SD > USB converter. if they weren't out of stock, i'd get more ... hope to replace all of my SD cards with these :)

Cons: none, thus far. if the hinges break (feels somewhat flimsy) that will be no good ... but it's all good, thus far.
