By Keith_Joseph HALL OF FAME TOP 50 REVIEWER VINE VOICE
Product Packaging:Standard Packaging
This is a 'new' advanced format hard drive that is designed [optimised] for 64-bit Windows Vista, Windows 7/8, and Mac OS X [Leopard 10.5, Snow Leopard 10.6 and above, but Boot Camp not supported]. Most Western Digital Advanced Format Drives can be used with XP if you put a hard drive jumper across pins 7/8 before formatting and partitioning [if you fail to do that or have multiple partitions under XP, you will have to use WDs 'Align utility' as well]. You also might occasionally get problems installing 6Gb/s SATA3 or 3Gb/s SATA2 hard drives on 1.5 Gb/s SATA motherboards [shorting pin 5/6 should rectify this].

However generally, if XP, Vista or Windows 7 is installed as the 32-bit version on your PC, it will not be able to format or recognise the full capacity of a 3Tb hard drive, either as an internal drive or as an external USB2 one. This is due to the 2.19 Tb limit with 32-bit operating systems. However owing to a hardware fix, this 3Tb drive can be used as a secondary drive with 32-bit Vista & Windows 7 [not XP] systems provided you use the PCI express [PCIe 1x] HighPoint RocketRAID 62X Serial ATA card, that Western Digital were supplying with this hard drive [the hard drive must be attached directly to this PCIe card]. This SATA PCIe card is sometimes called a 'host bus adaptor'[HBA card]. Also 32-bit and 64-bit OS's (including XP) can recognise this 3Tb drive if it's connected as an external drive via USB2 provided there is a special SATA-to-USB bridge chip inside the enclosure that takes care of these addressing issues, so to be safe with really old SATA PCs I'd buy this 3Tb drive within the Western Digital My Book Essential USB2/3 enclosure or get the Seagate 3Tb equivalent.

I wanted a large fast but green 3TB hard drives for my Hornettek Enterprise 4X (Quad Bay Enclosure) and this seemed like the most affordable option in the long run. Arrived very quickly and well packaged. Should hopefully last several years. I monitor all my PC's drives health using Acronis Drive Monitor (Free Tool) just incase. My 1TB PC internal Seagate SATA drive which is only 2 years old is showing a problem. However the 5 year old Seagate main drive SATA HD doesn't. Everyone has different experiences but i still believe that if one brand is good for you then stick with them. I highly recommend this drive!

5.0 out of 5 stars love them... 15 Mar 2012
Product Packaging:Standard Packaging|Verified Purchase
i have had Western Digital My Book drives for what seems forever now & fearing they MIGHT start playing up & loose data in the process i decided to buy the superlative NewerTech Guardian Maximus Raid1 FW800 enclosure without drives & ordered 2 of these here to install in it
unfortunately one was DOA but immediately after i contacted Avides/sent the defective back, i got a new one, inserted it in my FW800 Raid 1 enclosure & the NewerTech copied everything to the new drive &....life is good again !
they are quiet, they take loads of stuff & all things being equal + a little luck , i'm sure they will keep on going on strong for a long time

5.0 out of 5 stars Very nice drive with good response times 1 Oct 2011
Product Packaging:Standard Packaging|Verified Purchase
I have bought WD drives previously and have been happy with their reliability and performance. Whilst it is early days, so far I have not been disappointed with the pair of these which I purchased. I have experienced no issues as a direct result of the drives and the unit is keeping them working well.

On this occasion I have bought a pair of these 3TB drives to work in a dual drive NAS drive unit. A little over the top for the performance, but the price was very good and slightly better than the 3 GB/s option at the time. For the past few days I've been copying content to them, whilst also streaming some content from them. In preparation for these drives, I had updated the firmware on the NAS drive unit so that it can support 3TB drives before installation. You may also wish to confirm that you are using the latest firmware/BIOS/SATA drivers for you system as some older systems may have issues with the larger capacity these drives offer.

As with all SATA drives, it was a simple case of plugging them in, initialising, partitioning and formatting them. They were ready to use within an hour of arrival, but I know that formatting them for use on a PC would have taken a lot longer using the standard method (i.e. not quick format).

I have set them up using a RAID 0 configuration. This should ensure faultless HD Video streaming over my LAN, which will be their primary use. Whilst this configuration offers no data redundancy, the data isn't highly valuable. Any loss would be an inconvenience though. The unit does offer other RAID options which would support automatic data backup.

I intend to get a larger unit at a later date and would happily use these (or similar drives) if all works well in the mean time.

5.0 out of 5 stars Another great drive from WD 22 Feb 2014
By B. HALL
Product Packaging:Standard Packaging|Verified Purchase
I purchased on of these in 2011 to replace a collection of smaller drives. The drive is great, and has never given a single problem.
Same as every other WD drive I have had, and why I always buy WD drives.

As for the drive, I like the fact that it powers down and only spins up when you try to access something on it. This may be a problem for some users, but I think the power/heat saving is worth the 2 seconds, and the speed is great once it's up.

My machine is silent, using a case built for being unheard, a zero db video card, slow speed ultra quiet fans. So if this was noisy I would hear it, and I don't. I hear it spin up when accessed (not loud, audible), but then is settles to very quiet.

And the transfer speeds are excellent, even with my quite old PC. Considering I have a SSD and much older Blue drive, there is no noticeable speed drop for this being a 'green' drive.

There has been comments in other reviews about WD OEM drives having 1 year warranty and being 'out of region'.
The out of region was easily FIXED by updating the country on my WD account, so that is not an issue with the drives.
As for the OEM/1yr, according to the WD support site, drives with model number ending EZRX have a 2 year (component) or 3 year (Retail) warranty (check under support - Warranty Policy).
My WD30EZRX purchased as OEM from Amazon in 2011 had the 3 years, so I don't think this is an issue. But either way, you can check the warranty before you remove the drive from the sealed static bag.
