    Putting System Images & Something Else on the SAME USB External Hard Drive

    Am looking at purchasing 2 My Book USB 3.0 External Hard Drives.

    Best Buy has the 4 TB for $99.99 - the average price of a 2 TB one (Thanksgiving & Black Friday price).

    Was going to buy 2 2TB ones, but may instead buy 2 4TB ones for the same price.

    May partition each one into 2 partitions of 2 TB each.

    My Macrium Reflect Free System Image will go into 1 of the partitions of each of the 2 Drives.
    I always rotate drives each time I do another Image just in case 1 of the drives goes bad.

    2 TB is plenty enough space for System Images isn't it?

    The 2nd partition on each drive will be used to back up something else (my Desktop's Data Drive D, pictures, etc.)

    Is the above a good idea?
    Or should I not mix System Images with something else - even though they would be in separate partitions on the same drive?

    A 2TB parition should last you for a while, depending on how many images you want to retain.

    Most disk imaging software will allow you to select the compression level to help you control the size of the image file when it is created.

    I have done essentially the same thing for years...with no paritions. I use folders to store certain types of backups.

    I'm sure you'll get many suggestions, but IMO, doing a full disk image on a regular basis and storing it on an external device is fine, no matter what else may be on it.

    Steven,

    No problem storing other things on your huge drives. Just use a good folder structure to separate your Images and other stuff.

    I use folders with the appropriate machine name to store my images so it is easy to tell which image goes to which machine. Within a given folder I keep several versions of my images JIC! I also backup to more than one external device and I have the folder structure duplicated on each device. Of course, one of the folders is DATA...guess what goes there.

    Yes 2Gb is more than enough space as you can see below:

    Yes I'm a bit over the top on making backups but it's served me well over the years.

    THANKS to both of you for your input.

    I use folders a lot everywhere else, so not sure why I did not think to consider that instead of Partitions.

    Sure would be a lot easier to add or delete folders & subfolders, instead of having to partition the ext HDs & possibly have to change the size of those partitions later on.

    In another thread, I asked:

    Do the My Book External Hard Drives have a rated speed like the internal drives do?
    Or, is the speed determined by the USB 3.0 / USB 2.0 connection only?

    Paul T replied:

    Internally they will be SATA drives, probably with a 6Gb interface, but you will never see those speeds over USB.

    I subsequently got this information directly from WD in an E-Mail:

    Let me explain to you that the drive inside your external hard drive may vary depending on application. There are several things you should know about WD external hard drives:

    Depending on model, the internal hard drive in an external enclosure could be either SATA or native USB.

    We can only guarantee drive capacity. We cannot guarantee a particular internal hard drive model, data interface, rotational speed, or cache size in the external hard drive enclosure.

    Interface and cache of the hard drives inside the external enclosure does not affect the performance or the data transfer rate of the external hard drive unit:

    I don't know what Yara is trying to say but on a regular, well designed external USB 3. enclosure connected to a USB 3. port the speed should be much greater than a set up with either side USB 2 . Faster than SATA 2!

    Just because you don't know where you are going doesn't mean any road will get you there.

    Kind of late to be thinking about this - but:
    Will the entire 4 TB of both of my WD My Book External Hard Drives be accessible or is there a lower limit?

    I am using Windows 8.1 Pro 64-bit on a Dell Precision Tower 5810

    There may be a 2TB limit if the drives are connected to the motherboard, but USB should be fine. Try it and let us know how it goes.

    cheers, Paul
