32 GB Solid-state 2.5" hard drive announced

...I wonder if I want one of these solid-state drives in my MacBook Pro instead of the 100G drive that's in there now.

$350 per unit for large volume orders... I wonder what that translates to in retail.

Alternately, this could be seen as supporting data for the Apple solid-state ultraportable MacBook rumors that have been kinda flitting around the net.

Interesting, sounds like a very cool new technology. My initial thought is that I'd want to know a bit more about how the drive works before switching over. Unless they've improved significantly in the last few years, FLASH memory cells wear out after about a million writes. Totally not an issue in general, but I'd be somewhat concerned about the lifespan of some of the directory pages and other heavily-used areas.

OTOH, it's pretty easy for the drive to deal with this by just rotating heavily-used sectors through different physical locations in the chips. If they're doing something like that, there should be no problem, since it's going to take a long time before every sector sees nearly a million writes.

Flash lifetimes
Modern flash averages about 2 million writes for the `cheap' stuff, 5 million for the expensive. They get by with rotating which areas get hit, more or less exactly as you suggest, and also suggesting that you not swap to flash. This compares favorably with portable hard drives in use today and, bonus, you can leave the build running while carrying the machine around (assuming it can handle the heat).

Meanwhile, NAND drives are the new new thing.
