Summary: Wish WD would address this bios problem. Years ago, you could flash hdd bios with the first dos floppy, but it doesn't work anymore. A software program or a back up bios would greatly improve an otherwise great drive... from a dependability point of view.
Pros: This drive is about as fast as any ssd in a practical sense. It is also WAY more dependable than an ssd, and cheaper. I had two computers with ssd's, and ended up removing them both. These drives are "enterprise" level with a huge mtbf. Look it up for yourself.
Cons: Only problem with hdd's, is the bios. I lost 5 drives playing with raid configurations with different raid cards. They became "clickers". All were wd's (of course). Actually for light use, raid didn't help with speed of the machines.

Summary: I have been a fan of IBM/Hitachi HDD’s since 2000ish tried Seagate’s and after 2005ish Seagate’s have been horrible in reliability, my old IDE/SATA IBM/Hitachi’s still work awesome ( I am very abusive to HDD’s), but need faster HDDs, so I tried one of these 250gig HDD’s and have yet to look back.
Pros: Very good HDD so far I have 4 and plan to purchase more, despite comments on how loud this are they do make a VERY faint clicking noise when active, but so far quiet and run about 5-10+c cooler (under load) then my Seagate’s and about 5c+/- cooler then my pre-WD Hitachi HDD’s
Cons: Not at all a WD fan, in fact it took years to trust another WD HDD drive. All prior WD HDD’s failed within a year or so and the ones that have yet to fail make noises that you need ear plugs for (no joking) I don’t even use them for anything important due to they can fail at any moment.
Summary: ~2 Years of High school comptia training ~4 years of self-taught hardware nerdism (cold cathodes to custom cooling) ~1.5 years of Restaurant IT work
Pros: Super fast when in RAID 0. I have a SSD boot drive and use 2 of these for installing programs and games. They have been running about 8-14hrs a day sense 10/16/2012 without issues using the on board controller on my ASRock Z77 Extreme4 MB.
Cons: storage space. this is my own fault so i didnt knock off an egg. I went from having 2x 1T HD black in raid 0 to 2 of these in raid 0... going from ~2T storage to ~500GB feels... cramped.. its to the point where im installing games on my backup drive... I require more storage..
