According to the experts at XS, it looks like write endurance isn't a problem, random failures due to firmware may be a bigger issue.

Wow you really know nothing about encryption. Sigh.. Everyone is an expert. Zdnet looked at ighashgpu that's unsalted password decryption when you already have a precomputed hash table. TH looked at salted password decryption where you have to perform a SHA-1 transformation invocation thousands of times per every password attempt.

Right... except that anyone who has a desktop gaming system can do what TH did. It's not like they had a supercomputer.

rainbow tables only work on unsalted passwords. These were used by microsoft for 'lan' style passwords. IIRC, vista and win7 don't use these. And if you use a 14 character password or longer, even windows xp disables the lan encryption.
Your rainbow tables are effectively useless against aes-128, aes-256, and even des. They simply precompute password hashes, and generating the tables takes quite a long time.
Using rainbow tables has nothing to do with gpu acceleration.

No. Zdnet used ighashgpu. That's a hash cracker. WinZip and WinRAR encyption is different because it's based on precomputed password hashes. It looks like TH used AccentZip and AccentWinRAR to decrypt passwords.All three programs are created by Ivan Golubev. His blog is full of posts on cryptography performance.

but isn't every new password that you're trying technically different?

Interesting article, but I wonder if CPUs are only slower at brute-force attacks because there haven't been new optimized programs.

Tom's Hardware has an interesting article up on WinZip and WinRAR encryption strength, where they attempt to crack passwords with Nvidia and AMD graphic cards. Some of their results are really fast, like in the billions of passwords per second, and that's only with two GTX 570s!

An anonymous reader writes: We all know that the specs of your inkjet printer, driver settings, and ink cartridges can make a big difference in the quality of your prints. But the cheapest and simplest aspect of printing can also have a big impact on the final quality: the paper. This short article is an interesting read, the author actually found ways to 'benchmark' inkjet printer paper!
