TarDisk Pear – Grow your MacBook Hard drive !

Posted By Scott Paterson on Feb 15, 2016 | 5 comments


A little while ago I looked at a device called the Nifty MiniDrive a neat little MicroSD card carrier that fits completely snuggly into the SD slot on MacBooks adding disk space for photos/documents and other temporary files. They are relatively cheap and can be used with whatever size of MicroSD card you have available. The downside is that the disk space provided is a separate volume to the internal drive and as such you have to manage which files and folders go where. It is certainly a neater solution than plugging a USB drive into your MacBook but if the internal drive is struggling for space it doesn’t immediately solve that issue.

Then last night I came across a product called TarDisk Pear which uses the same idea of plugging extra storage into the SD card slot in a completely flush carrier but extends it to the next level. With the TarDisk Pear instead of the extra disk space being presented as an external removable volume the additional storage is magically used to extend the space available to the internal drive ! The web site doesn’t give many details on exactly how it does this but there are a few hints on the FAQ’s page where it talks about the risk of data corruption and loss if you remove the drive after it has been setup. Clearly the magic comes at a price.

Despite looking I couldn’t find any information about the impact on the performance of the built in drive either. I would hope that it manages the data in a way that optimises the performance of the internal drive but this isn’t clear from what I have seen.

Pricing starts at $149 for 128GB rising to £399 for 256GB.

  1. Scott, thanks so much for the write up! Would love to help answer any questions. In essence we are leveraging the power of a core storage file system. And it works pretty damn well.

    Any specific performance test you have in mind? We are constantly trying to push our hardware to its limits — would love to explore new ideas!

    • No problem Vicky. I did find the reference to performance on your site ( for readers you can access at this link http://tardisk.com/pages/pearinfo#details_bar and click on the red “Technical Info…” link.

      Its good to hear that postage to the UK is free and to be honest for £100 to try out the 128GB version I am tempted to give this a try even though I am not desperately in need of the additional space on my MacBook at the moment.

      This is a really interesting product and if it helps people extend the life of their MacBook for a relatively small investment without risking opening up the case and attempting an internal drive upgrade then I am sure it will be very successful..

    • Vicky, my MacBook is a Late 2013 Retina MacBook Pro ( 13″ ). When I go to order page the Review information says the device is compatible with Mid 2012 – Early 2013 MacBook Pro.
      I can’t see a way of modifying the selection to a Late 2013 MacBook ? Is this model not supported ?

  3. Absolutely you are supported! We converged our 13″ Retina MacBook Pro models into a new unified design. (formerly our old design required that the user figure out the year of their MacBook — we eliminated that!)There are two ways to find it;

    Here is a compatibility chart; http://tardisk.com/pages/chart or
