1 out of 5 eggsSad day in mudville

Pros: price

Cons: soo many bad sectors, the disk check utility from their website couldn't even check it.
I had a Seagate disk that could ... and 2 hours into the test, there were so many that I stopped it and called support.
NewEgg replaced quickly.

5 out of 5 eggsDrives Have Been Working Quite Well!

Pros: As a long-time system builder, I have had nothing but success with this particular WD series. After over a year, these drives continue to perform very well in every system that they've been installed. After all, isn't that what we're all seeking?

Cons: None.

Other Thoughts: For those not quite satisfied with these drives, there are many factors that can impact performance and/or reliability. Far too numerous to delve into here. Like people buying the same new car, sometimes some of us are just among the unlucky few to acquire a less-than-perfect product. That's simply how it goes in the world friends...

4 out of 5 eggsSo far, so good.

Pros: This new drive arrived in good condition, and upon being hooked up to the bench tester powered up without hesitation and formatted efficiently.
Ran it through the monkey jungle of testing:
Transferred a hundred gigs onto and off.
Defragmenting
Fast random file access.
All of them done quickly and without annoyance.

Once spun up, the drive is fairly fast for the type and operates without building much heat either. Very quietly as well.

Cons: Did not include a jumper.

Other Thoughts: If you are using Windows XP, you need to emplace a jumper on pins 7-8, prior to installing the drive in your system.
If you are using Vista or 7, no jumpering needed.

I'm only giving this a 4 egg due to the fact that the initial drive was DOA.

5 out of 5 eggsGreat Drive, just know the limitations

Pros: This is another great drive from WD. Reliable, cool running, and, well, Green. Also extremely fast in windows Vista/7 and Server 2008 OSes for a 5900RPM drive. The huge cache makes up for that slow RPM.

Cons: This is an Advanced Format Drive, which moves the sectors from every 512kb to every 4 megabytes. What does this mean to you? Better error correction ability and faster performance/less fragmentation. BUT, it also means that OSes produced before Vista cannot take advantage of this, and will in turn corrupt themselves while using the drive if the drive is not either periodically aligned or jumpered to the XP setting. This causes serious issues and in turn is why the reviews aren't all that good overall.

Other Thoughts: This is the drive for Vista/7 low power devices/large storage.

Otherwise, don't buy it. It will cause more headaches then its worth. I had to run out and get a 500Gb WD Blue for the client when I found out this wasn't going to work in Home Server (SBS 2003 based) and it just added another complication I didn't need.
