Primary Drive Choicesįor a 1.5TB drive, you can use the HGST (formerly Hitachi, but now owned by Western Digital), 1.5TB, 9.5mm drive, which fits with room to spare. If you’re willing to remove the DVD and replace it with a second hard drive, but wish to keep your shock protection for the primary drive, the max is now 4TB. If you’re willing to simply replace the hard drive with a larger one, using all stock internals and mounting, your max possible storage is 2TB. And for the record: The following information is valid for any unibody Macbook Pro of any size (13″, 15″, 17″), but NOT for Retina models (for what’s available in the Macbook Air and Retina area, see this. You have four different maximal storage capacities available to you, depending upon how “non-standard” you’re willing to get with your machine. For those wanting to use these drives internally, who don’t want to have to open a USB enclosure to remove them, they are available as bare drives as well. So the short of it is, yes, they will work in place of the original hard drive, but look at the photos below to determine whether that’s right for you. Note 6: Update from 2-2016: Seagate has now released a 2.5″ 3TB and 4TB drives, but it is important to note that these drives are 15mm, which will not fit without issue inside your machine – this is the same size as the Western Digital drive shown in the pictures below.


Note 5: With the release of 2TB SSDs, it’s now possible to fit up to 4TB of SSDs in your Macbook Pro or Mac Mini. Note 4: Update from 4-4-2015: And it gets even easier – 2TB, 9.5mm (standard height) bare drives are now widely available as bare drives. It is now possible to put 4TB into the Macbook or Macbook Pro, using the methods outlined below, with no fitment issues. Note 3: Update from 3-9-2014: This all just got a lot simpler, due to the release of this Seagate 2TB Slim drive. Note 2: This post has been updated again on 1-2-2014 with the latest available drives, not least of which was Toshiba dropping their 1.5GB Aquarius offering. Note: This post has been updated on 9-7-2013 with the latest available drives, which gives more you more choices (and more capacity) than the original post. So the question becomes, “Just how much space can I fit in that machine?” And the answer is, “It depends upon how badly you want it.”

Perhaps you’ve got…ahem…150k photos to tote around, or you’re a active gamer, or maybe you’re just a major pirate…either way, most people who keep a computer for more than a year or two are likely to want to want to upgrade the hard drive sooner or later.
