Pros: I bought two of these when they were $179 for use in my unRAID media server. I use one as a parity drive and the other along with a 2TB for actual storage. They are both just about full with only ~200GB free. The media server is used fairly hard in my household and these drives have performed wonderfully.

Cons: With the recent flooding in Thailand, the price is skyrocketed just when I need more storage.

Overall Review: None.

Pros: It's the fastest 3TB drive on the market. The packaging was better than expected, a lot better than the WD drives I have purchased from Newegg in the past. It came in its own box and it was shrink wrapped to the box to keep it from moving around.

Cons: None so far, but I've only had it for a day. I'll keep you posted if I find any.

Overall Review: I will update this review in the future to give a better review on its performance. To the people that are commenting on this that do not own this drive, stop it. You are dragging the rating of this drive down by rating it 3 eggs. The rating should be about the quality of the product. What you are doing is making potential buyers of this drive wary of buying this because of its low average rating.

Pros: Huge Capacity. I needed more space for my movie drive in my HTPC, and this HDD is the perfect size. Quiet, responsive, and doesn't run too hot.

Cons: None so far.

Overall Review: Works great with both Windows 7 32 & 64 bit. Just plugged them in, and was off to transferring my movie collection over to them. I already have a 3TB external to back up this HDD, so I am good to go. Ridiculous to see some commenters marking the large capacity as a negative.

Pros: This is a message to Rich Z, who complains that he's not getting any more "speed" from a Sata III connection vs a Sata II connection. Although there are Sata III SSD drives that can outrun the bandwidth of a Sata II data channel, there isn't a conventional Rotating/Mechanical hard drive in the world that can do the same. Max theoretical bandwidth from a Sata II channel is 3Gbps - a little over 300MBps, but the fastest mechanical hard drive in the world isn't half that fast. So then, you may ask, why do manufacturers make Sata III hard drives? Because high-end HD controller cards use SAS to Sata fan-out cables that convert one SAS connection to 4 Sata connections. Under that scenario, 4 fast Sata II hard drives will experience a bottleneck. Hence, to get faster data transfers, you have to increase the bandwidth of the Sata channel. Thus, Sata III allows you to gang 4 drives together and still have excess bandwidth left over on the data channel.

Cons: none

Overall Review: You should really delete your review so as not to confuse other people who don't understand the difference between the "speed" of the data channel vs the "speed" of the device attached *to* the data channel.

Pros: There isnt a flaw with these drives, we have probably purchased in excess of 100 of them in the last 3 months. Great drive...if you are using in a system with a backplane, just make sure you get one that has been qualified to run at SAS/SATA 600 speeds as some of the older backplanes that are qualified with 150/300 speeds can't auto negotiate the drives down to 300, so you end up with them all running at SATA150.

Cons: *Newegg can't pack hard drives* We needed some drives, but not quite a 20 packs worth so we ordered 10. When they arrived they had the bottom of a 20 pack, but they didnt use the correct top, just a flat piece of foam. On top of that, the drives were packed upside down according to the markings on the exterior of the box, so of course when the box was opened by shipping and receiving the drives were all over the place in the box because I am sure that they spent the better part of their journey what should have been "rightside" up. A couple drives were just DOA. Then we noticed that drives were intermittently failing during the array build process. It should be noted that sitting right next to this system were 5 identical systems, same internals, all operating as they should, arrays built and verified without issue. With drives failing left and right we took all of this systems drives and placed them in a known good unit and placed that units drives in the problem system. The known...

Overall Review: (Continued from above Cons) ...good drives built and verified fine in the "problem" system, and the known good system kept failing with the set of drives from newegg. Swapped them back around and once again the problems followed the newegg packed drives. We decided to just send them all back because we could never trust an array to so many questionable drives even if we weeded out the ones that were failing since the potential was very high that we would see further failed drives from this shipment. We absorbed the restock fee of over $200 and had our usual vendor break up a 20 pack and overnight them in. I would HIGHLY recommend against buying a somewhat sizable order from newegg unless you can just buy a unbroken 20 pack. We have ordered singles or a quantity of 2-3 without issue. Newegg has gotten a bad rap in the past for shipping hard drives using less than desirable methods, and in some areas they have improved. Obviously they still have some work to do.

Pros: Works great. SATA III My backup has completed to this drive without incident. It will hold multiple backups which was my goal. ATTO Benchmark transfer rates: Read 153 MB/sec Write 151 MB/sec Faster than my Western Digital SATA III drive (120 GB/sec)

Cons: 3TB became 2.72TB after initializing disk. GPT partitioning scheme used.

Overall Review: Using Windows 7 - 64. Windows asked which partitioning scheme when I was initializing disk thru Windows Admin Tools ; MBR or GPT?? For windows to use all 3TB as 1 partition I am using GPT. GPT will eventually become the new standard. Do not use GPT if is this will be your system drive. This is my backup drive. I did NOT use the suggested download software from Paragon for this drive. I did add the Windows optional update for drives Larger than 2TB drives.

Pros: I bought 5 of these drives to put into my Synology DS1511+ in a Raid 6 format. I back up using time machine for my macs and it also functions as the backend for my XBMC media players. The speed of these drives exceeded what I thought. The large capacity a big plus. I am able to output 3 different blu-ray rips to three different TVs without a hiccup. I am very satisfied with these drives

Cons: None so far.

Overall Review: I would buy this again if I need additional storage space.

Pros: Works perfectly in a Mac OS X 10.6.7 Raid 5/6. I have a 39TB Raid 6 using 3TB Ultrastars. SuperDuper at night backing up to another 39TB Raid 5 using Deskstars. Fast enclosures. R/W on the Ultrastars.... 1200MB/s. On the Deskstars its 450/545. This system is used primarily for Final Cut users over a 10GB EtherNet network. No problems so far.

Cons: none, other then two of the UltraStars were sent back as DOA.

Overall Review: Been using Hitachi drives for the past couple of years. Use to like Seagate but quality fell apart for me three years ago. WD I never liked that much. Too many failures in their enterprise line.
