Best SSD for Macbook Pro 2012: Buying & Installation Guide

Are you using an old mid-2012 MacBook Pro and you want to upgrade the machine with an SSD (solid-state drive)? If yes, then this guide is for you.

I'm going to share the best SSD for MacBook Pro and show you how to install it properly, so you waste no time and make no mistakes.

P.S. I went with Crucial BX200 480GB SATA 2.5 Inch Internal SSD (see below for my purchase receipt), and I'm quite happy with the performance it has brought to my Mac. But, it is now a legacy product and Crucial has several new better options like MX300 525GB. Yep, the SSD market changes fast.

Quick summary

If you use your MacBook Pro for lightweight tasks such as surfing the Internet, storing pictures, etc., a cheaper yet high-capacity SSD is best for you. Crucial MX300 is my top pick, followed by Samsung 850 EVO, and the third is SanDisk X400.

If you use your MacBook for heavy tasks like gaming, video editing, 3D modeling, etc., a pricier yet high-performance SSD is best for you. Samsung 850 PRO is the best, and OWC Mercury Extreme Pro 6G is great too.

Why should you trust me?

First of all, I use a 13 inch Mid-2012 MacBook Pro, and I have successfully replaced my Mac's internal hard drive (500GB Hitachi HDD) with a shiny new Crucial SSD which cost me about $140 (tax included) by the time I purchased it in 2016. See these screenshots for evidence.

I'm using a MacBook Pro (13-inch, Mid 2012)

And yep...it's with an SSD now!

I spent about $140 buying the Crucial SSD in 2016, tax included.

Here is what happened to my MacBook Pro and why I decided to replace the hard drive with an SSD. The quick answer is: I had to.

Around April 1, 2016...yep, Fools' Day but it wasn't a joke 🙂 My Mac went black screen all of a sudden, it stopped working, and I couldn't turn it on. After sending it to Apple Genius Bar for diagnosis, the geek guy told me it was because the internal hard drive attached to my Mac died and he said the only solution was a replacement. To me, it was devastating! The 500GB Hitachi hard drive was working okay for the past four years, and there wasn't any sign for it to strike until it happened. As a result, I lost some documents and pictures which failed to be backed up in time. Lesson learned ... the importance of backup!

I began to shop around for solid-state drives. For two reasons: first I read that SSDs beat HDDs over many aspects (more in the following section). The other is the fear of HDD failure — yes, I hated Hitachi HDD for a while and decided to give SSD a try. After that, I did as much research as I could ... both online (reading industry SSD benchmark tests from StorageReview.com, CNET.com, TechReport.com, AnandTech.com, etc.) and offline (asking computer repair shop technician for advice), and I ended up with ordering a 480GB Crucial BX200 SSD on April 5, 2016.

After the SSD was delivered, it took me another two days to manage the installation process ... opening the hard case, watching OWC and iFixit video instructions, installing OS X El Capitan, etc. the list went on and on. To be frank, I made quite a few mistakes before I got everything right. Finally, the SSD was running smoothly on my MacBook Pro.

But, you don't have to make those mistakes, as I'm going to share all that I've learned along the way in this guide. My goal is simple: to save you time exploring what the best SSDs are and avoid pitfalls you might encounter during the installation process.

What are the benefits of installing an SSD for Mac?

The debate of HDD and SSD has never stopped. HDD, stands for hard disk drive, has a much longer history and continues to be the mainstream. SDD, short for solid state drive, uses a new storage mechanism and starts to get more traction as its price declines which happened just several years ago. Both HDDs and SSDs have pros and cons. General speaking, HDDs beat SSDs in price and capacity limits; while SSDs are superior to HDDs in performance and durability. If you are interested in learning more, this or this article is worth taking a look.

There are good reasons why you should consider installing an SSD on a Mac machine. In fact, Apple has started to use flash storage in almost all its computer product lines, MacBook Pro included. Flash storage is storage that uses electronically erasable memory modules with no moving parts, similar to what a solid state drive has to offer.

  • Your Mac will be much faster. Case in point, once I installed the new Crucial SSD to my 2012 MacBook Pro, the performance increase blew my mind. Let's take boot time as an example, in the old days, my Mac took nearly a minute to start up entirely. Now it's only 10 seconds or so; I'm always amazed to see the startup progress bar flash through...no more spinning wheel. Besides, a Mac with an SSD transfer files faster and launches and runs apps faster.
  • It will be more silent. Since an SSD is non-mechanical, it makes virtually no noise unless the fans spin up. A quiet Mac is better than a noisy Mac. Unlike SSDs, mechanical hard drives contain spinning platters and magnetic heads. It's normal to hear a whining noise or clicking and tapping when the drive is spinning up or accessing data.
  • SSDs are more durable. One main factor that leads to traditional hard drive failure is the heat created from continuous motion generated by small moving parts. Only 78% of the hard disk drives we buy are living longer than four years, according to Backblaze. Because a solid state drive does not have any moving parts, it is more reliable thus safer for the data you'll save or create on your Mac.
  • SSD price is dropping. According to Lucas Mearian from PCWorld, "The price computer makers paid for solid-state drives (SSDs) declined by as much as 12% over the last quarter", he noted later "SSD adoption rates in laptop computers will grow by more than 30% this year." It's safe to say that SSD price still has room to decline as competition goes on.

Things to consider when choosing an SSD for Mac

Okay, now that you're ready to shop for an SSD and retire the old hard drive on your MacBook. What type of SSDs should you get? Here are some factors you should consider.

Your budget. Although the price of SSD has been falling, the range still varies a lot. For example, the cheapest SSDs cost more than a hundred US Dollars while the most expensive ones are priced at over $1000 which could allow you to buy a new Mac machine. So, the first thing is to ask yourself — how much can I afford to get an SSD for my MacBook? For example, between $100 and $150, or around $200, etc. Note: a cheaper SSD does not mean it's not good, there are many other factors such as drive size, the brand, etc. that affect the price.

Storage capacity. The volume of an SSD is one of the most important factors you should consider. At this moment, it's not common to see SSDs available for sale that is less than 500GB in size. In other words, 500GB is almost the base capacity you could choose from most manufacturers. This is because smaller drivers are often slower and more expensive considering the cost per gigabyte. Also, as camera technology improves, photos and videos often have much larger file sizes. If you are used to syncing these files with your Mac, the chances are that your Mac will be filled up much faster than ever before. So, consider a 750GB or 1TB if you have a need for large storage. You could consider 4TB, but in my opinion, it is an overkill, and a 4TB SSD is usually way more expensive.

Performance need. There is a saying in the storage world that even the worst SSD is miles ahead of an HDD in terms of speed. But not all SSDs are made equal. Drives with larger capacities tend to be faster in writing and reading, thanks to an SSD's speed advantage that comes from parallelization. But the difference wouldn't be night and day. For most MacBook Pro users, a cheaper yet high-capacity SSD is enough to meet your daily computing needs. For those of you who make a living in fields like design, development, or workstation, etc. that requires a MacBook pro to move large files and handle request very quickly, then consider a high-budget, high-performance SSD.

The brand. Buying an SSD is a big investment, and it's serious business as the drive carries all your personal or business data. You don't want to get an SSD that is insecure, defective or from a manufacturer that doesn't offer quality customer service. That's why choosing a brand is important. In general, I buy products from brands that are trustworthy like Apple, Samsung, Crucial, SanDisk, etc. For SSD manufacturers, another factor why brand matters is that quality and warranty. For example, during my research, I know Samsung makes its own SSD controllers, memory, and firmware, which gave me confidence that the company is capable of designing and putting together the entire SSD from start to end. Also, brands like Crucial and Samsung all offer 3-5 year warranty for their SSDs...another bonus.

Mac compatibility. Not all Macs support SSD upgrade and not all SSDs fit into the Mac model you own. For example, the most recent MacBooks are all with SSDs and they are blazing fast and based on 4-channel PCIe interface (Source: 9to5mac), there is no need to upgrade unless you have particular reasons. If you are using a Retina MacBook Pro or Air that was made mid-2013 or later, it's almost impossible to upgrade the hard drive because PCIe-based SSDs don't use standard connectors. Even if your Mac like MacBook Pro/Air prior to 2013 is able for SSD upgrade, you should be careful because Macbooks don't use standard SSD designs and MBPs and Airs share different types with each other. Fortunately, MacBook Pros from 2012 and before are compatible with 2.5-inch SATA drives which most SSD manufacturers provide.

Best SSD for MacBook Pro: 5 great options

For general users who prefer a cheaper yet high-capacity SSD, Crucial MX300 is my top pick, followed by Samsung 850 EVO which is as great as Crucial. In case both options went out of stock, SanDisk X400 is an excellent alternative.

For power users who are less price sensitive and have high-performance demands, Samsung 850 PRO is surely a winner in the market. If it is not available, OWC Mercury Extreme Pro 6G is a great option.

Pro tip: once you secure the desired SSD, we also suggest you get the NewerTech 14-Piece Portable Toolkit — which includes Phillips #00 screwdriver, a Torx T6 screwdriver, and other tools you'll need to open your MacBook PRO case to get the SSD installed.


As I said in the beginning, I've been using a Crucial BX200 480GB (now a legacy product) with my mid-2012 MacBook Pro for about eight months — without any problems! I wholeheartedly recommend Crucial SSDs. MX300 is popular because of its price advantage and various capacity options (from 275 GB to 2TB). Regarding performance, both CNET and TechRadar gave it a 4-star rating.

What's Good:

  • Price is very competitive
  • Strong security with hardware encryption
  • Plenty of features

What's Not So Good:

  • Decent performance but not the fastest SSD
  • Only 3-year warranty

Samsung 850 EVO has remained the #1 best seller in SATA SSDs for two years thanks to its many merits such as high speed, 5-year warranty, and technology — which I mentioned earlier that Samsung is able to design and make key SSD controllers and parts on its own. Another perk for choosing Samsung is its Magician software, which is great for drive installation, maintenance, and faster transfers. StorageReview rated it "an incredibly impressive drive."

What's Good:

  • High performance
  • Up to 4TB in size
  • 5-year warranty

What's Not So Good:

  • The Samsung Magician software only works with PCs, not Macs

SanDisk has word of mouth among its memory cards and flash drives. The company also makes solid state drives. SanDisk X400, relatively new to the SSD market, aims primarily for business notebook upgrades. The SanDisk X400 has four capacities that range from 128GB to 1TB. What impressed me most is its performance, which is as good as Samsung 850 EVO, and X400 is a bit cheaper as AnandTech called it an underpriced product.

What's Good:

  • Greater endurance with SanDisk's nCache 2.0 technology
  • 5-year warranty

What's Not So Good:

  • Does not come with software like Samsung Magician

The Samsung 850 PRO is essentially an upgraded version of 850 EVO. PRO is designed for gaming and professional computing, while EVO is for everyday computing. The differences are that PRO has higher maximum sequential read speed (i.e. up to 550 MB/s) while EVO is up to 540MB/s; And PRO features with 10-year warranty versus EVO with 5-year. Plus, PRO is lighter. But, Samsung 850 PRO is much more expensive than 850 EVO.

What's Good:

  • Excellent performance, much faster than 850 EVO
  • A lot of useful features and capacity options
  • Mindblowing 10-year warranty

What's Not So Good:

  • It's much more expensive
  • Samsung Magician software is not available for Mac users

OWC, stands for Other World Computing, is a computer hardware provider since 1988. I got to know the brand when I was searching for video tutorials about how to open my MacBook Pro case. The OWC team has created tons of really awesome videos that make it hassle-free to replace any Mac components all by yourself. The OWC Mercury Extreme Pro 6G SSD features high-quality and supports disk encryption.

What's Good:

  • Great performance
  • Useful video tutorials for SSD installation

What's Not So Good:

  • Price is a bit higher than that of competitors

How to install a new SSD to your 2012 MacBook Pro?

So you've bought and received your desired solid state drive (and perhaps the screwdrivers and tools needed to open your Mac case), now what? Open the case of your MacBook Pro and put the SSD inside? Wrong. You'll need to make sure you've backed up all the data on your old hard disk drive (if it's still working) and created a bootable installer for macOS (see how to do this in Step 2).

Note: if the internal HDD in your MacBook Pro has crashed or died (as happened to my MBP, sadly), I highly recommend you schedule an appointment with Apple Genius Bar. Their Geek team will install the latest macOS for you, so you don't have to take the time to make a bootable installer. Also, you don't need to buy any screwdrivers or tools as they will open the case for you as well.

Step 1: made data backups of your Mac hard drive

The easiest way is to use Time Machine. You can also clone your Mac hard drive to an external drive. Cloning is complementary to backup methods like Time Machine, and I encourage you to do so if you have extra portable drives. The goal is to ensure you can get up and make your Mac work again in minutes in case any system crash/errors during update.

Step 2: create a bootable USB installer for macOS

The USB installer allows you to quickly boot up your Mac just in case, especially when the Internet Recovery option isn't available to use. All you have to prepare is a USB flash drive with a capacity 8GB or larger because the file size of the macOS Sierra installer is 4.86 GB (and OS X El Capitan is 6.12 GB). Read this article or this article for how to make it.

Step 3: open MacBook case and replace HDD with SSD

This is the key part that you need to be extra careful. Any mis-operation could damage your Mac. Fortunately, OWC has recorded a detailed instruction in this video. I highly recommend you watch it before you start.

Step 4: Install macOS and transfer data

Once you finish the SSD replacement work, plug in the USB flash drive (with the bootable installer you made in Step 2) to your MacBook Pro. Now press the start button to turn on your Mac. Hold down the Option key as soon as you hear the reboot tone. Select the disk named "Install macOS Sierra (or OS X El Capitan)" and install the operating system to your MacBook Pro. After that, use Time Machine to restore all the data. Follow the instructions from MacRumor. They are quite helpful.

What is TRIM & do I need to enable it on my SSD Mac?

For Mac computers, TRIM is a command that helps macOS system know where the data you want to delete or move is stored. The main benefit of enabling TRIM is to make it faster to write to empty memory thus prolong the life of your SSD. Do you really need to enable it? In my opinion, no. Because I haven't noticed any slowdown with my Crucial SSD (yet). Plus, Apple didn't support TRIM for aftermarket SSDs until OS X 10.10.4 (source: AppleInsider).

How to check if your SSD is TRIM enabled or not on your MacBook Pro? Click on Apple logo on the top left corner > About This Mac > System Report > SATA/SATA Express, then select your SSD disk and check "TRIM Support."

In my case, it says NO because I haven't enabled TRIM.

If you want to enable TRIM, this CNET article shows you how to do step by step. You can also watch this YouTube guide if you prefer video tutorial. Just a kind warning: before you proceed, make sure you backup your Mac just in case.

5 tips to keep your SSD-based Mac in good shape

In the digital age, nothing lasts forever. Every piece of hardware and device has a lifespan. Eventually, it will be gone. An SSD drive is no exception. All we can do is try our best to extend its life and maximize the value. Even if it fails someday, it won't cause panic. Here are several useful tips:

  • Always backup your SSD data to another place, be it an external drive or cloud storage, it doesn't matter. Backup is the only effective way to avoid data loss disasters.
  • Never erase or format your SSD drive. You've learned the difference between how HDDs and SSDs work, there is no need to wipe an SSD clean by making unnecessary write cycles because doing so will only degrade your SSD life.
  • Update firmware from your manufacturer. Most solid state drive providers like Samsung release firmware updates regularly. It's always a good idea to visit the manufacturer's website and install the firmware.
  • Do not use up all your SSD storage space. Even if you've chosen a small-size SSD for your MacBook, aim to have at least 10% free space. Clean your Mac on a regular basis with apps like MacBooster 5.
  • Avoid exposing your SSD and MacBook to extreme temperatures. Although SSDs are more durable and resistant than HDDs when it comes to cold and hot, leaving your SSD-based MacBook Pro in such environment too long is a bad idea for sure.

Conclusion and feedback

When your old MacBook Pro runs slow or starts to act up, you need to watch out as there could be something wrong with the hard drive. In my case, I've personally experienced HDD crash with my mid-2012 MacBook Pro. Fortunately, you don't need to abandon your old Mac and get a new one. Replacing the internal hard drive with a solid state drive has been a proven way to boost your Mac performance, to a great extent.

However, choosing the best SSD for your MacBook isn't an easy task as many factors are out there for you to consider. I hope the buying guide above has given you some directions. Whether you are a general user who's selected a Crucial MX300, or you are a power user who has secured a Samsung 850 PRO, they are all good SSDs for Mac machines.

Also, don't underestimate the installation part as it could be quite time-consuming if you don't have the right tools at hand. I hope you find the guide and tips I shared useful. If you have any additional questions regarding SSDs for Mac, leave a comment below.

Disclaimer: the MacBook Pro SSD review and guide are primarily based on 1) my own experiencing shopping and installing a solid state drive on my mid-2012 MBP; 2) the expertise of SSD and computer experts with whom I consult; 3) the information accessible via the manufacturers' websites. As thus, the above recommendations are my own opinions and I reserve the rights to change my opinions when necessary.
