    Hi,

    I have a 27 inch 2012 imac computer and I wish to purchase an usb flash drive to use as a recovery backup for the Mountain Lion operating system.

    I would appreciate any suggestions as to what brands to get as well as what size drive to order (8 or 16 GB).

    Thanks in advance for any advice you can give me with selecting an usb flash drive! :)

    Thanks for your quick reply! Would the "PNY 8GB Hook Flash Drive" be sufficient for my iMac computer?

    Below is the link for the usb drive:

    Does it make a difference if the speed of the usb flash drive is 2.0 or 3.0 as my iMac computer comes with 3.0 usb ports? Thanks! :)

    If the Flash chips inside are the same speed it won't matter, btw, USB 2 is already much faster than most if not all USB flash memory sticks.

    Edit: Experience Accelerated File Transfer and Backup

    Up to 190MB/s which IS much faster than USB 2 can deliver.

    Well, either will work, however a 3.0 flash drive would be faster on your iMac.

    That might depend on the thumbdrive . My USB 3.0 drive read is much faster that writing to it.

    That's a USB 2.0 drive, ergo reinstalling the system will take ages. You would be better off with something like the LaCie RuggedKey.

    But, if you use it a lot and need sheer speed, the Mushkin Enhanced Ventura Plus is the fastest 16GB drive, the read speed is rated a little faster than the SanDisk Extreme USB 3.0, then again if you want to repurpose it later, the SanDisk has faster write speeds and looks better.

    Also, you know that your 2012 Mac has Internet Recovery if you press Command+R when turning on, which makes the USB stick obsolete, right? :)

    Even a USB 1 stick would be faster than that, but a USB 2.0 stick would definitely be faster, since you would have to download 4 GB via a 6 Mb/s line, which would take 1.5 hours to download. Even when I use my Mac OS X 10.6 Snow Leopard installer from an external USB 2.0 HDD I can install in less than 30 minutes, sometimes 15 to 20 minutes I guess.

    If the USB 3.0 stick would have flash modules that offer a significant speed, like 50 or 80 MB/s or even more, than a USB 3.0 stick would be quite good, but as USB 2.0 offers 35 MB/s already, it might be overkill for an installation medium.

    CCC to USB stick slow?

    CC cloner took 3hr to clone Osx 10.8.1 ML to my usb stick on my 2012 mnini. Normal? Does that mean its gonna take that long to copy it back to my SSD?

    Yes most likely, many files to copy.
    No, reading that USB stick is most likely much faster.

    It was most likely a USB stick with slow write speed, as doing the same with a USB HDD takes about ten minutes.

    I've decided to go with a 3.0 usb flash drive, instead of the 2.0 version (to use as a recovery backup for the Mountain Lion OS) and would appreciate suggestions for an inexpensive option? Thanks! :)

    True enough... but if you ever need to DL a 4.7GB installer over hotel wifi, you will wish you had the USB key installer. I carry one with me on trips.
