1. Amazon (at the time I am writing this) is listing the drive as 6Gb/s. Western Digital's website indicates that the drive is only 3Gb/s (the WD25EZRX is their 6Gb/s model of this drive). This is a typo and Amazon has taken care of my order as a result.
2. Anyone not familiar with large format drives needs to be aware that the drive will need to be formatted with GPT partitioning in order to utilize the full capacity of the drive. If you plan to boot Windows (64-bit only) from the drive, you will need to also have a UEFI compliant motherboard (with EFI boot enabled) and a Windows installer with a UEFI boot image. For example, the Windows 8 upgrade DVD created by the upgrade tool does not have this enabled by default.
Those issues aside (not the drive's fault), the drive is working fine so far, is very quiet and remains cool. I don't believe getting the 6Gb/s model is going to provide any benefit over the 3Gb/s. For high performance drives, you're not going to be looking at a Caviar Green anyways.
Pros.. A lot to list. These are very quick drives for Green. They run very cool and have no problems at all keeping up with 3 or 4 HD streams at once. I have 2 of these in DirecTV HD DVR's, running for about a year with no issues.
On the other hand, it is not fast. Used as a storage unit, it is adequate. The drive's biggest problem is reliability. Since this hard drive's introduction in 2009, users have consistently reported premature failures and data corruption. These complaints were well warranted, for the manufacturer has shorten the life cycle of this computer component by design.
The source of the problem is Western Digital's attempt to make the device "more green" - use less electricity. One way to accomplish this goal is to park the heads on a plastic pad after eight seconds of no read/write requests instead of allowing them to float over the spinning platters of the hard drive. This adds up to 10,800 cycles each day. The numerous scrapings gradually wears out the heads. According to some literature, 250,000 to 1,250,000 cycles will result in damage that will lead to read/write errors. If you do the math, data corruption will begin within 23.148 to 115.741 days if you are employing the hard drive on a heavily used server. Regular consumers will not notice read/write problems until later. Some WD drives reported 3,000 to 5,000 cycles per day. At this rate, the first instances of data corruption will begin within 83.33 to 250 days.
From my experience, early data loss will not be noticed by the average user. There are no signs of trouble if work files are not accessed, edited, and save. With numerous usages, lost sectors on the hard drive appear and indexes become corrupted. Then, damages become apparent.Read more ›
So apparently Western Digital warranties this drive for 2 years from purchase date, so they're sending me a replacement. +1 additional star for that. They also appear to have some kind of upgrade program which I didn't research much, but I assume would have given me credit for the broken hard drive and I could have used that credit toward a larger Western Digital drive. I might have pursued that if I didn't already purchase a Seagate 4TB replacement for the broken one.
