Pros: Very affordable, low power consumption, and FAST!

Cons: The firmware upgrade procedure is every bit as miserable as everyone says. I installed this in a netbook with no ability to boot media other than USB sticks. You don't even want to know what I went through to make the firmware upgrade work (hint: it involved Knoppix, qemu, and formatting the SSD itself with DOS 6.22). Seriously, Adata needs to just release a bootable ISO image based on Linux or FreeDOS to make this a one-step operation. Still might not have helped much in my particular case, but for the vast majority of users it would help a lot!

Overall Review: I bought this drive in an attempt to make my extremely-frustratingly-slow Lenovo S10 run at a reasonable speed. It already had Xubuntu and 2G of RAM; it really seemed like the 5400 RPM hard drive was the problem. And it was! I installed this SSD, put Ubuntu's netbook edition on it, and it's faster than I ever thought possible! Boot time is 20 seconds from pressing the power button to "click your user name to log in," and at least 8 of those seconds are just the POST. This drive saved me from having to buy a new netbook/laptop.

Pros: Looks like it'd be a nice motherboard if it worked.

Cons: Dead on arrival. Sometimes wouldn't boot at all, other times would get as far as the initial boot screen with the ASRock logo, but there were weird vertical artifacts flickering across the screen, it would not respond to any keypresses (tried two keyboards, one PS/2, one USB), and it never got any further than that. The CPU, RAM, power supply, etc. all work fine with another lower-end ASRock motherboard.

Overall Review: I'm sending this back for replacement and I'll update my review when I get the new one.

Pros: Everything works as expected.

Cons: None so far.

Overall Review: Another reviewer was complaining that they only got 460 megahashes per second mining Bitcoin with this card. I don't know what they were doing wrong, but I'm getting 630 megahashes per second without even tweaking anything (using bfgminer on Linux). I bought this card for bitcoin mining and it works exactly as expected. Someone else mentioned that they got the wrong power adaptors with their card. The ones I got were correct - two old-school Molex connectors to a single 8-pin PCIe graphics power connector. I got two of these with my card, which makes sense given that the card requires two 8-pin power inputs.
