The Caviar Black model of drives differ in three ways from Blue in three major ways:

1) 32MB buffer vs 16MB. This means the drive is overall faster because it can store more data in memory local to the drive. So if you access the same data frequently there is little or no drive access to get at the data.

2) Dual processors vs single. This will alleviate the load on your CPU as the drive itself has more processing power locally.

3) Five year warranty vs three. Five years is a lifetime in hardware. Basically, you're covered for longer than you will most likely use the drive.

The Caviar Black line comes in three four sizes; 1TB, 750GB, 640GB, and 500GB. The 1TB and 640GB are the fastest because they use a denser platter technology which allows the drive head to get at the data quicker. The 750GB and 500GB are no slouches though and the differences in speed will not be noticeable to most people under most real-world usage scenarios.

Caviar Black drives are the fastest affordable consumer drives available today. If you want faster you have to look that the VelociRaptor 10000RPM line of drives but expect to pay a lot more for a lot less storage.

I measured the speed of the 750GB model using the HD Tune utility and access time was a fast 12.5ms with less than 1% CPU usage on my 3.2Ghz Intel Quad Core setup. The drive runs cool at 32°C in my system and is quiet. Overall a great drive at a great price. You can't really go wrong.

I bought two of these. Just an insane price. Thanks, Amazon. The drives are bulk/OEM which means they come with nothing. Just the drives and the anti-static bags. Do your homework. If you want software to hold your hand through a hard drive install, do not buy this drive. If you need screws, rails, or cables, do not buy this drive.

If you want to save some cash while getting an absolutely absurd amount of disk space with SATA2 (3Gbps) plus 32MB of cache (older drives have 4-16MB), then get these drives. They are beasts.

After the Seagate fiasco, I vowed to go with an alternative. Western Digital came through with these monster hard drives. Get one. Get two. You will not be disappointed.

I bought this drive for my Mac Pro (Mac Pros, at least when I bought mine 3 years ago came from Apple with WD 250 GB hard drives). I have installed about 10 WD drives, upgrading this time form the WD 500GB drives, and this drive with its 32MB cache is indeed a bit faster (10-20 percent) than the 500GB. The ONLY downside at all to this drive is that is a bit louder when the heads are seeking, with the drive seek "clatter" more noticeable than the previous 500GB Western Digitals I just replaced (I needed more storage). Not bad tho--it's just that my Mac Pro is absolutely silent and I notice the least little additional sound and never really heard the 500's, the 1TB I hear now--but don't get me wrong it's not bad and there certainly is no drive "whine" when idling--these are quite drives. I guess whizzing across 1TB of data is a little more strenuous on the heads. I have bought about 20 Western Digital drives since 2000 and not one has failed on me--unlike LaCie--ick.

This is for people (like me) who've never done this before... I use Windows Vista and an HP desktop computer.

1. Ordered this drive, which arrived promptly. Drive was well packed with foam. As expected, it didn't come with anything else. It works fine, and to me it doesn't seem noisy.

2. Ordered Tripp Lite P940-19I Serial ATA (SATA) Signal Cable (19 Inches). Note: older computers won't support SATA. If you have a newer computer, it should work. SATA cables are red and about 1 cm wide, the older cables are about an inch wide and silvery. If your hard drive uses these, don't get this drive.

3. Ordered Tripp Lite P946-12I Serial ATA (SATA) Dual Power Adapter Cable - 4pin/2x15pin SATA - 12in. This is a "Y" adapter (optimistically planning for my next hard drive!), but a straight one would also work. I found out after it arrived I already had a SATA power adapter in my case. However, it wouldn't have reached with the available wiring length, so I still ended up using this.

4. In my case, the drive requires 4 screws to install it. These are short screws with large flat heads, the heads form a sort of "rail" for it to glide into the rack on. On opening my case, I realized that HP had thoughtfully provided extra screws for future upgrades! The drive does not come with screws.

5. Installed drive in rack, plugged in the two cables, no problem.

6. Get to Windows. Your new hardware icon should say "locating... installing" or something like that.

7. Go to Start-Computer (right click on Computer) - Manage - then to Disk Management. Find your new drive at the bottom of the screen, and click over the "drive 1" (or whatever) designation to make it "online".

In all fairness this isn't a problem with the WD (although I did have two WD fail on me within one month), it's a problem with Amazon's shipping. Haven't had a problem with items that Amazon has shipped (but I have with external vendors) but this package was ridiculous. The drive arrived with two deflated strips of plastic. Even if they were fully inflated I would not be happy with the packing at all, not nearly enough. Funny cause when I order a pack of CDs they are shipped in two boxes with two levels of padding. Huh? The drive was also scratched up.. it was odd because the packaging though damaged didn't have any way to scratch the drive (cardboard vs steel, no match). I have a feeling it was refurbished or at the very least repackaged..

Do better next time plz..
