Top Customer Reviews
I just purchased a second drive and did some testing on it while blank and uploaded the results under customer images to the right.
UPDATE: After a long back-and-forth I was finally sent a brand new drive which functions fine now. Upgraded from 1 to 3 stars.
UPDATE: Have now received my second replacement drive for original warranty and it's no good either. This time they want me to pay for return shipping! This company is terrible. Lawsuit, lawsuit, lawsuit...........really this how NOT to take care of a customer.

I have to compare these to other drives I have purchased in the same design and competition, doing so these have exceeded all other brands I have bought in the last year. The test I have specifically for these drives was ran on from Windows 2008r2 server Xeon X3430 16gb RAM with a LSI 9260 controller that had 6 WD red3tb drives in a RAID 10 configuration. Keep in mind the 3tb drives are only a 5400rpm drive while the 4tb and above were all 7200s. Had i known this when i bought them I would have bought the 4tbs.
The pictures below are the speed tests I have locally on the SAN. Much higher than I can achieve over 2x1gb connections. So all is good from what i see!
First thing to look for is to observe the packaging the drive arrives in. It is industry practice to ship one or more drives in boxes that are made to perfectly fit the drive. Inside the box, the drive should be suspended with two plastic holders. These holders suspend the drive and dampen any drops the package may experience during transit. (Bulk orders (15+) may be shipped in a single larger box with foam cut-out arrays).
Secondly, when installing the drives, make sure that your hands are clean. Give them a wash, or better yet, wear gloves. Avoid transferring finger/hand oil to the drives so that hot-spots aren't created.
Thirdly, once the drives are installed, give them a full, long format. You can run 1, 3, 5, (or even more) passes on the disks. This ensures that every single sector of the drives gets written to. Once the format is complete, look up the SMART data, and check the values for anything alarming. If a drive suffered damage in shipping, now is when it may be noticeable. Compare the values to your other drives. Start-up times, head parks and so fourth may vary slightly so there's nothing to be worried about a little deviation there, but pay attention to failed reads, reallocated sectors, and RUEs.
Granted, all of this advice should be taken with a grain of salt since SMART values are not the silver bullet to predict drive failure, but this testing should be a good indicator on whether or not a drive is ready for production use.
Above all else, remember that backups are your friend.
