Pros: Huge space. Got it for a great price with newegg promo. Good looking enclosure.

Cons: Until I updated the firmware, the drive had issues staying mounted during file transfer (running OS X Mountain Lion.)

Overall Review: Not that looks trump performance, but this is one of the best looking external drives I have owned. The black finish is smooth and ultra soft, almost feels like velvet. Wife-approved styling. But more importantly I want to address the issue that some have reported with mounting problems under OS X. When I first plugged in the drive, it mounted and I began copying some files. Part way through the transfer, the drive unmounted and gave me an error. I tried again. Same thing. Transfer would get part way through and then unexpectedly unmount and fail. So I downloaded a new firmware driver from Seagate, and it solved the problem completely. No more unmounting issues. The drive now works great. The firmware update process was not super intuitive, so I want to make sure everyone knows the process (the first time I ran it, I was fooled into thinking my drive was already up to date, but it actually wasn't.) First make sure your drive and all other external drives are disconnected. Run the firmware updater. The updater will tell you that no drive was detected. Plug in your drive. The updater will then detect your drive and give you the option to update firmware if your version is out of date. *** When I first tried updating the firmware, I had the drive already plugged in. The updater then did not detect an eligible drive, thereby fooling me into thinking mine was already up to date. So, run the updater, then plug in the drive. I'm pretty tech savvy, so I'm bugged that Seagate phone support had to walk me through this, but there you have it. Their phone support was quick and helpful, by the way. I've only had the drive a couple days, but I like it so far. I'll update down the road if any other issues come up. I considered giving it 4 eggs instead of 5, because of this issue, but since Seagate was quick and helpful, I am keeping it at 5.

Pros: Good price, fast. Worked well for a couple months.

Cons: High failure rate for me.

Overall Review: I own 3 of these cards, and as of today 2 of them have died. Today I was in the middle of transferring files from the card to my computer, when the card suddenly died. It is no longer recognizable by any system, PC or Mac. My card reader still sees other cards, so it is definitely a problem with the card itself. I have now lost valuable and costly video footage. Very unhappy with these unreliable cards. Other people seem to like them, so maybe I am a fluke, but I will not be buying them again.
