No, unfortunately the SD card slot on the Retina MacBook Pro is 1mm deeper than the rest of the MacBook range. Please tell us that you want the MiniDrive Retina if you plan to use the MiniDrive in your MacBook Retina computer. You can do this when we send round the backer email survey at the end of the campaign.Last updated:
Yes it is, please choose the MiniDrive Pro for best fit with the iMac.Last updated:

We strongly recommend getting the correct MiniDrive for your version of MacBook.
However, the MiniDrive Air can go in MacBook Air, Pro and iMac
The MiniDrive Pro can only go into the MacBook Pro and iMac.
The MiniDrive Retina can go into the MacBook Pro Retina, MacBook Pro and iMac.
- if you use the MiniDrive Air in the MacBook Pro or iMac, there will be a small gap either side of the SD card slot. The MiniDrive Pro is designed to fit completely flush.
- if you use the MiniDrive Retina in the MacBook Pro or iMac, the drive will stick out from the body of your computer by 1mmLast updated:
Short answer: Yes, flash memory wears out. No, it won't be a problem!
Long answer: A typical microSD card has a write cycle durability of 10,000 writes per bit. As modern microSD cards are designed to write evenly across the entire bank of memory, theoretically, any bit that has just been written to should not be written to again until all other bits have been written.
In practice, you will have some bits sitting idle as you often will keep certain files for an extended period on the drive (i.e. only reading those bits), while others are changed regularly. However, on the provision that the drive is never completely full, and you do a full re-write every time you use it, you will generally have a fair degree of latent memory that any write cycles may be spread over.
As a result you will have far more than 10,000 writes of your drive before you see any failure. In the most extreme example; you should be able to do a reformat of the entire drive, 10 times a day, for 3 years before there is a memory failure (if you were really going for broke to get one!). Under normal use, you should not experience memory failure.Last updated:
You will need to do a little investigating to find this out.
The dimentions of the MiniDrive are : 21.5mm (depth) x 24mm (width) x 2.3mm (height)
The depth measurement is critical - if your SD card slot is deeper than 21.5mm, it will not be able to read the MiniDrive. Less than 22mm and you should be fine (but it may stick out a bit).Last updated:
The MiniDrive has no restrictions on the format or speed of MicroSD card used within it.
The limiting factor for you will always be the speed/compatibility of the SD card reader in your Macbook Air/Pro.
According to Apple [http://support.apple.com/kb/HT3553] the maximum speed of the SD card reader in the current readers is 480mbits/s - this is approximately 60mb/s.
So, any card up to a read/write of 60mb/s is perfect.
Additionally (for those still reading) - write speeds are generally a lot slower than the read speeds on a MicroSD card. This means that even if your card can be read at faster than 60mb/s, if the read speed is at or below 60mb/s you will still see a decent performance lift over slower cards.Last updated:
The short answer is, maybe. The MiniDrive will work with Windows or Mac, but it all depends on how deep you computer's SD card slot it.
The easiest way to measure the depth of the SD card slot in your computer is to put a normal SD card into it, draw a line on the SD card where it meets the body of the computer, pull the SD card out and then measure how deep the SD card sits.
If the SD card sits 22.5mm or less in the body of your computer, you can use a MiniDrive!
Here are the dimensions of the MiniDrives so you can work out which one you need.
All dimensions below are length x width x height
The MiniDrive Air: 21.5mm x 24mm x 2.3mm
The MiniDrive Pro: 21.5mm x 26mm x 2.3mm
The MiniDrive Retina: 22.5mm x 26mm x 2.3mm
The most important dimension is the depth. If you computer's SD card slot is too deep then the MiniDrive won't work.Last updated:
