Excerpt: I bought three of these drives to use in my Netgear ReadyNAS. So far, they are running at temperatures that are significantly lower than the two 500 GB drives they replaced, This bodes well for their long term reliability. Data access is fast with no hassles, as it should be for this type of device. Overall, I'm very pleased.
Summary: I hope I dont have to edit this later.... I have purchased at least 10 of these drives. None have failed or given me an issue. The RPMs are not 5400 as stated in another comment, but vary between 5400 and 7200RPM as needed.
Summary: It works perfect as a NAS drive as it should. I like the variable speed 54k thru 72K which helps with performance when you need it and energy savings when you don't. I do think it's just a bit pricy for a 1TB. but then again, not by much. As a suggestion to others, WD REDs are NAS (Network Storage) drives, not desktop drives and should only be used as such.
Summary: I originally bought this to replace my boot drive. It would work for a while and then shut down the machine. I changed it to be a storage drive. Again it works for a while and locks up the computer. I thought at first that I had a computer problem, but it only happens when this drive is connected. Without it, all the other drives work fine.
Summary: This review is actually a supplement to my previous review where I reported that 50% of disk I ordered did not work. I just went through RMA process at WD. Well, it turns out that receiving defective disk is going to cost a customer some money. They are paying only 50% of the shipping costs! Moreover, they REQUIRE to send each disk in a separate box.
Summary: I just wanted to RMA the drive like a reasonable customer and shouldn't have to quibble over stupid things like this.
Pros: Great value for what you pay for.
Cons: I went to install this drive into my company's RAID 40 bay RAID enclosure and the SATA power connection separated into the tray. I though nothing of this and requested an RMA with Newegg to replace the drive. In the RMA I specifically pointed out "The drive functioned correctly but when I removed it from a drive carrier in a storage RAID the SATA power connecter came apart. The piece of plastic that typically supports the pins in now stuck in the carrier." So Neweegg ...
Excerpt: I bought six of these to replace 250 GB Seagate and Hitachi drives with 45,000+ hours in a RAID configured Netgear ReadyNAS. The most notable difference is that these are running 11-13 degrees F cooler than the replaced drives. Performance is good; they are quiet; obviously too early to judge reliability, but the temperature differential bodes well.
Summary: The last thing I want is to lose a TB worth of data. So I bought this drive which is built for NAS and meant to be used very often. So I figured I'd pay a little bit extra to have my data more secure. In benchmarks, it seems to have performed better than other similar drives too. Overall, a very good product, especially if you wanna do RAID; even if you don't.
Pros: Built to take a beating.
Cons: A bit more expensive than regular hard drives but not by much.
