Many people are recomending the WD 8mb because it provides new technology at a reasonable price. You see WD, Maxtor, and Seagate on the market the most because they are best prices for the storage capacity and features. However..., just because they are sold a lot doesn't say squat about their reliability. Remember that if a person is building a computer for retail sale, what are they looking to do? They are looking to maximize features and benefits, sell it for the lowest price and make the biggest profit. They do this by buying feature packed, low quality products. They know that the products have a warranty so they aren't out any money, and you have a potentially unstable system. As has been discussed, there is a warranty. But if you will go back in time a little to the well known film "Tommy Boy" and remember one of his infamous one-liners about putting a guarantee on a box. If you would like I can take a dump in a box and mark it guaranteed, but all you're getting is a guaranteed piece of crap (edited for content). Look at Windows, it is the best selling OS, but it isn't the best thing out there and it certainly isn't the most reliable or stable. It's called advertising and good deals to the computer makers. Unless you specify the drive you want when having a customer computer made, the manufacturer will almost always install a mediocre drive. Its how they make money. It is no fun for anybody to have to take the drive out to have it warrantied. It takes a lot of work and time to restore your system to pre crash conditions and hope that you can salvage your files off the drive. There are just certain components you shouldn't skimp on unless the computer you are building is for gaming or other unimportant stuff. If it is your primary piece of computer equipment, get a good motherboard, hard drive, cooling fans and modem (if you surf). The ram across the board is pretty stable unless the board manufacturer specifies an approved maker. The floppy drives and CD-Roms are simple to replace if they fail and don't affect the operation of the PC. The graphics card is basic, but if you do a lot of gaming, get one that is at least somewhat reputable like GeForce or ATI or something. Anyway, my custom built computer is stable and enjoys good performance for the money. It's always about the money.
