Summary: I am a system builder and have been using Western Digital for over a decade. Rarely do I receive a bad unit out of the box. I question whether or not they test the drives at the factory. It took the Western Digital Data Lifeguard app about 30 seconds to figure out the drive has bad blocks.
Pros: Its a good price point for the performance and stability promised
Cons: I purchased 2 of these drives for a RAID. 1 of 2 is defective right out of the box, WD Data Lifeguard says its bad blocks that are not repairable.
Summary: I always test hard drives right out of the box using the manufacturer's diagnostic software. I've been bitten too many times by new drives being defective. These drives were bought to replace seven year old WDC 500GB drives that were causing problems in a RAID10 array on an Adaptec 6805E.
Pros: Fast enough. Works well in a RAID array.
Cons: One out of four had too many bad blocks making it a brick.
Summary: From Western Digital's Site: The model number you receive from us may vary from the model number that you shipped in, or that is listed on this screen. Due to product availability, we sometimes will make substitution with similar or better products.
Pros: I use these on the enterprise level for our customers; these are typically reliable and are TLER enabled so that RAIDS aren't an issue.
Cons: Bought this drive for my personal use about 2 months ago for my file server. Got some clicking noises and the drive would not provision on my raid controller; DOA. Not a big deal, drives come DOA and this drive was only going to be added into a RAID 5 pool so no hurry to get this in. My fault for...
Best Enterprise Drive on a budget, great for a Mirror-er Boot Pool.

Summary: These are WD original Enterprise Drives. They do the job and do it well, as fast as you are going to get without spending extreme $$$. Its safe to say I have purchased over 100 WD drives, and have had to RMA no more than 3 of their Enterprise Drives. If they fail, they tend to do it early..
