Today Mikhailtech take a look at Western Digital's 1000JB SE, a 100gb HDD featuring 40gb platters, an 8mb cache and tons of performance.

The drive itself it extremely well built. The upper portion is standard: metal casing, sticker, air hole. The underside, however, is what surprised me. For one thing, the circuitry is reversed. That is, all the chips and most of the traces are on the inner side of the drive, therefore preventing possible damage. There's also a layer of foam in-between to further lessen vibrations, add impact cushioning and protect the drive. I didn't particularly feel like removing the PCB to see what's on the other side (after all, this was a rush-delivered drive that is now my main system's powerhouse). There isn't much interesting aside from an 8mb Nanya memory module which happens to be the cache. The 1000JB SE also seems a bit quieter during operating than the only other drive I had available, the 60GXP. I wish it were as quiet as Seagate's Barracuda IV but I guess you can't have it all. For one thing, it doesn't hiss as loud and neither does it "crackle" when being stressed. As far as heat goes it stays about as cool as most drives.
