Final Words

At $239 for an internal drive, the 3TB offering isn't too expensive. You can shave off another penny or two per GB if you go with a smaller drive, but if you want the space of a single drive Western Digital's offering isn't a bad deal. You have to go into this purchase with the right expectations however.

The performance difference between the 3TB Caviar Green and a modern 7200RPM drive can be significant depending on your workload. We saw WD's 3TB drive perform a lot like a notebook hard drive depending on the workload. If all you're using it for is to store large files, photos, videos, etc... then you'll be fine. But I wouldn't recommend using it as a boot/application drive, the random performance and even light workload performance just doesn't measure up.

The 3TB drive (or a pair of them in RAID 1) would be a great companion to an SSD for all of your mass storage needs. As SSDs grow in size and popularity, I'm not sure we'll need to have 7200RPM hard drives in desktops any longer. These sub-6K RPM drives may be enough to get the job done. Sequential read/write speed is within 10% of Seagate's 2TB 7200RPM Barracuda XT, and I suspect that's all you need if you have a very fast SSD for your OS and applications.

As far as the external drive goes. Kudos to Western Digital for a well executed chassis, however I am concerned about the somewhat erratic read/write performance I noted in my testing of the drive.

    It was slooooooooowwwwww, but on top of that, disk utility was reporting a smart failure.

    This drive equals the suck.

    Boooooo

    Hi Anand, I bought a mybook 3tb usb3 drive with the intention of using it to store Hyper-V VHD virtual disk files.

    Hyper-V is reporting that it cannot use drives with 4k sector sizes (way to go, microsoft). I have heard that the built-in WSB (same engine used for win7 backups) also has this limitation.

    Do you know if there is any way to get 512b emulation on the MyBook drives, or do I need to return this drive and go with a different solution?

    Thanks,
    Wes

    That bundled PCIe-card really looks like a 4-port card. Maybe that's why the HighPoint’s drivers won't work - they have altered the card a little bit and removed port 3 and 4 plugs as excessive? But the solder bases looks to be there on the circuit board. I wonder if you could make it into a 4 four port SATA card just by soldering the missing SATA data-ports to their bases on the board. I mean I already thought about bying this HDD because I have all the SATA ports in use on my MB, and this would give the possibility of adding not one but two more HDD's - who knows, it that's four with a little tweaking. One PCIe lane should be more than enough to drive 4 mainstream HDD's for the average user.

    If a 3TB drive is only formatted to < 2.19TB, would that remove all complications of booting from it?

    (Odd question, I know. But I'm buying a new system, for which I already own a boot drive I want to reinstall the OS onto; but the system builder requires that I buy the new system with the OS [Windows 7 Pro 64-bit] pre-installed; I'm just wondering if they only format a 3TB hdd to < 2.19TB, will booting from it will be issue-free?)

    Is WD using the same HD model in the 3TB My book as the internal package? The stand-alone drive costs around $215 or more while the 3 TB My book is now available for less than $180. i was thinking about putting two of the drives in a Synology DS211+ enclosure (Raid 1) - it looks a bit like it is cheaper to buy two My Books and rip the drives out.

    Does anybody know if it is possible to replace the hard disk of Western Digital 640GB My Book for a new one with 3TB ? When replacing only the disk, should I perform any particular step? Thank you.

    I have an Western Digital 640GB My Book, I would like to replace the hard disk to another WD 3TB, but I am not sure if it will work, does anybody know if this is compatible or even if I have to perform any additional step? Thank you
