    So i'm planning my storage for the purchase of my riMac, and honestly looking at some of the external hard drive options they just look so bulky and ugly these are mainly the powered external hard drives but I was wondering would it be possible to use maybe a smaller 2TB Western Digital like this;

    http://www.amazon.co.uk/Passport-Ul...420410659&sr=1-6&keywords=external+hard+drive

    As a permanent external hard drive option as opposed to one that needs plugging in to a mains power source? would it work ok in the long run? as I know they are normally intended for portable use but I worry about their reliablity in the long term when compared powered external hard drive like a lacie, it's just that I prefer their small footprint and was wondering if anyone else uses this option as opposed to a big external hard drives that have a power plug.

    It doesn't really matter which hard drive you buy, you need to keep backups as well so as you aren't relying on the single hard drive to keep your data safe.

    I've used plenty of portable hard drives and while they last a few years, I've always kept backups when they fail.

    See I think i've got it covered (I think) i'll get two of those 2TB WD passport drives, use one as my primary storage and it'll be plugged in pretty much all the time into the back of the iMac while the other will get used to perform weekly backups of data from the first drive giving me an up to date copy of all my files just incase the first one dies on me.

    The biggest difference will be mainly speed. Normally desktop HDD are faster. (and not just in numbers, it will be clearly noticeable when dealing with large files).

    So it depend on how do you plan to use your external drive and if speed is important enough for you.

    I think an external SSD may be worthy of your consideration. They are fast.

    Portable HDD

    I have two, a 1TB Seagate and a 2TB Western Digital, plugged into my iMac. I've had them for over a year and neither has had a problem — so far. Each drive is partitioned, so that I can direct different file types to each. Examples: the WD has 1.3TB for my photo library and .7TB for Time Machine. The Seagate has .5TB for Carbon Copy Clone of the SSD and .5TB for photo backups.

    All the above are backed up to a WD MyCloud NAS. iMac SSD and photos are also backed up to BackBlaze. I'm paranoid.

    To answer your initial question, portable HDDs are good. I access my photo library on one to do post processing in Lightroom. I have virtually no lag. I'd say for normal daily work you should have no difficulty. BUT, they're HDDs so be sure to implement additional backup options.

    The main problem is bus-powered portable hard drives are usually slower than externally powered drives. There are some exceptions: the HGST Touro S is a 7,200 rpm drive that does about 130 megabytes/sec: http://www.touropro.com/en/product/touro-s/

    The previously-mentioned Seagate Backup Fast is a 4TB bus-powered drive that internally uses two 2TB drives in RAID0. It's very fast but sometimes may require two USB connections to source enough power. I think a single connection is OK on an iMac.

    There are nice-looking externally-powered hard drives from companies like G-Technology that are aesthetically matched to the iMac: http://www.g-technology.com/products

    If you only need 1TB and want a bus-powered drive, I'd get the Touro S -- it is inexpensive and very fast.

    They're fine to use when left plugged in, but any external drive is going to be less reliable than an internal drive just because you might smack it when it's reading data or something crazy like that...you never know what might happen. I'd use BackBlaze to back up your machine and external drive offsite, and then a really big plug-in hard drive that you keep hidden for local backups.

    Using 2 Seagate 1TB USB2 Portable Hard Drives. One used solely for Time Machine and the other is my ' working ' hard drive. Will upgrade to 2 or 3 TB USB3 as and when.

    Perform a monthly copy to a Seagate Desktop Drive.
