Apple doesn’t let you upgrade the Mac mini with inexpensive third-party components such as RAM or internal storage, and it prices its custom-build options at the very high end of affordability. Like the rest of the Apple silicon Macs, the Mac mini, Apple has fixed the RAM to the processor and the SSDs to the logic board, so they can’t be swapped out after you buy one.

Upgrading the M2 Mac mini: Adding memory
Apple integrated the RAM right into the M2 chip package in the Mac mini (2023) and Mac mini (M1, 2020) and so it can’t be upgraded. You must instead configure the amount of memory you want in your Mac mini when you purchase it. Unfortunately, there’s simply no way of adding more RAM to the Mac mini after you buy it. Depending on the model you buy, there are three options: 16GB, 24GB, and 32G, which cost up to $400. If you need more than 8GB of standard memory, you’ll have to pay for it at the time of purchase.
Interestingly, while discussing upgrades and technological advancements, the strides in the iGaming industry with digital payment solutions are worth noting. As gaming platforms look to enhance user experience, integration with payment systems like Apple Pay is gaining momentum. This collaboration is streamlining the transaction process for players and fortifying security measures
Upgrading the M2 Mac mini: Adding storage
Like the RAM, Apple has soldered the SSD (solid state drive) storage onto the Mac mini’s logic board, meaning that you can’t remove it and plug in a new one. As with the RAM, you must instead configure the amount of flash storage you want in your Mac mini when you purchase it. However, there are, however, several ways that you can upgrade your Mac mini with extra storage.
SSD or HDD?
Solid-state drives have no moving parts. Data is stored on interconnected flash memory microchips, which allows for data to be pulled from many different places at once and significantly increases memory read speeds. Hard disk drives (HDD) rely on spinning metal disks to read and write data.
SSDs speed up boot times, improve the responsiveness of your programs, and generally make your computer feel faster. However, you’ll pay more money for the same storage capacity on SSDs as HDDs. SSDs cost more per gigabyte than mechanical HDDs and aren’t often available in ultra-high capacities. Even as prices of SSDs continue to drop, HDDs will always be cheaper.
A good strategy is to use an HDD for backup, secondary storage or archiving, and an SSD for the files you work on every day. We recommend a backup drive at least twice as large as the total capacity of your Mac—for example, if you have 1TB of storage in your Mac, a 2TB backup drive will allow you to make a full backup while keeping other files or archived backups on the same drive.
For both HDD and SSD, there are many trusted storage brands, including Samsung, Seagate, Crucial, and Kingston.
External storage
The simplest way to add storage to a Mac mini is the same as any other Mac: Connect an external hard drive or SSD using one of the Thunderbolt ports on the back of the computer. Even the slowest SSDs are faster than mechanical hard disk drives (HDD), but look out for speed differences—entry-level SSDs provide speeds of around 500MB/s, while more advanced models can step up to 1,000MB/s or even 2,000MB/s.
External HDDs are a great solution for backups and archives as speed is less of an issue, and the prices are much cheaper than SSDs. No HDD, unless combined in RAID with others, can outstrip the 5Gbps (roughly 500MBps real-world after overhead) throughput of USB-C. Where Thunderbolt definitely helps is with RAID hard drive setups, or more likely an external SSD.
Another way to add inexpensive portable storage is via an SD or microSD card—once the go-to storage format for camera users but also a great format for cheap and portable backup and archive storage. Sadly, the Mac mini doesn’t have a card reader slot, so you’ll need to add one, such as this UGreen USB-C SD Card Reader for $13.
But there are admittedly ugly methods. You’ll have wires hanging out of the back of your Mac mini and a desk cluttered with drives.
Internal storage
The best option is to get more internal storage in your Mac mini, but Apple’s custom-built pricing means upgrading a 512GB model to 1TB will cost you an extra $200, and 2TB will cost $600, while M2 Pro options cost even more: 4TB is $1,200 and 8TB will set you back a whopping $2,400. Additionally, having the storage soldered to the logic board makes it faster, so if you can afford it, it’s the best way to go.
However, if you can’t swing the prices for more storage or just decide later that you need more, there are hardware solutions that connect to the mini without messing up the footprint of the small computer. Two of our favorites are the Satechi Stand & Hub for Mac mini with SSD Enclosure ($100) and the OWC ministack STX ($280), which feature bays for both an SSD drive and a 2.5- or 3.5-inch SATA hard drive.
Either of these Mac mini hub features upgradeable and inexpensive internal storage plus a range of extra ports. They both support the slim M.2 SSD form factor that resembles a stick of chewing gum. At the time of writing, we could find SSD drives from respected brands for $50/£50 (1TB) and $150/£120 (2TB). 4TB can be found for between $250 and $500—around a third of what you’d pay Apple to boost the internal Mac mini storage.
Foundry
You can add internal storage up to the maximum compatible SSD you can find inside the Satechi Stand & Hub for Mac mini with SSD Enclosure and OWC ministack STX. Installation is simple, with everything bar the SSD board itself included (screwdriver and screws). It’s a little fiddly but nothing to be worried about—if you can use a screwdriver, you can install the SSD board yourself.
Foundry
Note that the Satechi Stand & Hub’s enclosure does not support NVMe (Non-Volatile Memory Express) SSDs, while the OWC ministack does. NVMe M.2 SSDs are designed to be faster by using a more direct path to a computer’s processor over PCIe.5, so if speed matters, the OWC hub is a better option. That said, the NVMe slot on the OWC has only one lane of PCIe allocated to it, so the performance is limited to 770MB/s in real-world use.
Another advantage of the OWC miniStack STX is the second drive bay, which supports a 2.5- or 3.5-inch mechanical hard disk drive (HDD). These old-school hard drives offer far-greater storage capacities at a much lower cost than SSDs. 2TB HDDs can cost around $50. A 12TB HDD might cost under $200.

Upgrading the M2 Mac mini: Adding front-facing ports and extra expansion
While the Mac mini has plenty of ports around the back, Apple did not bless the Mac mini with any ports at the front like the Mac Studio. That means you’ll need to reach over to connect a peripheral device—which could be tricky if you’ve slipped the very hideable computer out of sight.
But there are options for adding them. For example, the Satechi Stand & Hub adds several front-facing ports. At 5Gbps, they aren’t as fast as the mini’s back-racked 40Gbps Thunderbolt 4 ports, but they are handy for micro thumb drives that you might want to plug in. You also get SD and microSD card readers, which are super useful for adding inexpensive portable storage. You can buy a Samsung memory card with 256GB of storage for under $30/£30 and half a terabyte for around $50.
The OWC ministack STX, on the other hand, mimics the Mac mini with no ports on its front. But its back has more powerful connectors than the Satechi hub. It boasts four 40Gbps Thunderbolt 4 ports (one upstream to the computer) and three 5Gbps USB-A ports, but lacks card reader slots.
Another port-adding option is to buy yourself a Thunderbolt 4 hub. Our favorite is the Caldigit Thunderbolt 4 Element Hub, which features four 40Gbps Thunderbolt 4 ports (including one side-mounted upstream to the computer), four 10Gbps USB-A ports, and a power supply. We’ve tested the best Thunderbolt hubs and docks if you want even more ports than that. Granted, they won’t be as neat as the Satechi Stand or OWC ministack, but there are tons of options out there.
Upgrading the M2 Mac mini: Adding faster ethernet
One of the build-to-order options offered by Apple is to upgrade the Mac mini’s ethernet from Gigabit to 10 Gigabit. As with the RAM and storage, once you’ve picked your Ethernet speed, there’s no way to upgrade the internal connector later. But you can buy adapters quite cheaply. TrendNet has a 5Gb Ethernet adapter that connects to one of the mini’s Thunderbolt ports. OWC sells a 10G Ethernet Adapter, although it’s actually more expensive than the Apple built-in option.
Note though that just having a 10GB Ethernet port on your Mac doesn’t automatically 10x all your networking. There are few 10Gb routers available, and even fewer that don’t resemble a rack mount unit from a data center. And they aren’t cheap either. If your ISP is offering 2.5Gbps, 5Gbps or 10Gbps, be prepared to replace your existing network gear to actually use the higher speeds.

Upgrading the M2 Mac mini: The ultimate setup
It may be over the top for many, but my eventual Mac mini upgrade solution incorporates both the Satechi and OWC hubs. At the bottom sits the OWC miniStack STX, with a 3.5-inch 4TB HDD and 1TB NVMe M.2 SSD, plus its four fast Thunderbolt 4 ports (one used to connect to the Mac mini). Above that, and with its handy range of front-facing ports, is the Satechi Stand & Hub for Mac mini with SSD Enclosure. Inside that, I have a 2TB M.2 SATA SSD.
And sitting on top is my M2 Pro (12‑core CPU & 19-core GPU) with 32GB of RAM and an internal 1TB Apple SSD. As the Mac mini ships without a keyboard or mouse, I stuck with Apple’s trusty Magic Keyboard and Magic Mouse.
As I was replacing my trusty old 27-inch iMac (vintage 2015 and starting to show its age) I needed a decent-sized monitor for my new Mac mini. I chose the 27-inch Alogic Clarity display, which is 4K rather than a 5K Retina but features a terrific adjustable stand that makes the old iMac look positively static.
1. OWC miniStack STX
Pros
- NVMe M.2 SSD bay
- 3.5-inch HDD bay
- 4x Thunderbolt 4 ports
Cons
- No front ports
- No card reader
- Black only color choice
Compatible with: Mac Mini M2 & M2 Pro 2023; M1 2020; Mac mini 2018; Mac Studio 2022
Size: 7.8 x 7.8 x 1.5 inches
Ports:
- 4x Thunderbolt 4 ports (40Gbps, 15W)
- Internal SSD enclosure
- Internal HDD bay
This double drive bay Mac mini accessory is a decent Thunderbolt 4 hub in its own right—hence its higher price tag compared to the USB-C Satechi hub.
Its four Thunderbolt 4 ports allow you to create three independent daisy chains with up to five total Thunderbolt devices with a USB device on the end of each chain (eight devices total).
But the real benefit of the miniStack STX is its bays that can be pre-configured or self-installed with one 2.5-inch or 3.5-inch hard disk drive and one speedy NVMe SSD.
Buy an inexpensive (but trustworthy HHD for a Time Machine backup or secondary storage, and a faster SSD for operational file storage. The miniStack STX offers the best of both worlds in terms of storage flexibility.

2. Satechi Stand Hub for Mac mini with SSD Enclosure
Pros
- SSD bay
- Front-facing ports
- Card readers
- Silver color matches mini
Cons
- SATA SSD not faster NVMe
- USB-C not Thunderbolt
Compatible with: Mac Mini M2 & M2 Pro 2023; Mac mini M1 2020; Mac Studio 2022
Size: 7.8 x 7.8 x 0.9 inches
Ports:
- 1x USB-C (5Gbps)
- 3x USB-A (5Gbps)
- SD card reader (UHS-I, 104MBps)
- microSD card reader (UHS-I, 104MBps)
- 3.5mm audio jack
- Internal SSD enclosure
This inexpensive USB-C hub adds much-needed ports to the front of your Mac mini setup. These ports include SD and microSD card readers, which are lacking from the mini itself.
You can buy a slightly cheaper version without the SSD enclosure but we advise spending the extra $20 even if, right now, you don’t think you need any extra storage. If your Mac mini has a 512GB internal SSD, then a 1TB or greater SSD within the hub offers excellent and speedy Time Machine backup or just extra space for your files. Remember you can’t go back and increase the capacity of the Mac mini’s integrated SSD.
While the SATA SSD is not as fast as a more modern NVMe SSD, it’s much faster than a mechanical hard disk drive and not much slower than the NVMe SSD in the rival OWC miniStack, which is limited to 770MBps data transfer to the computer.
The lack of Thunderbolt is not a problem if the two (M2) or four (M2 Pro) Thunderbolt 4 ports on the back of the mini are all you require. Note that one of the mini’s Thunderbolt ports will be used to connect the hub.

Pros
- Four Thunderbolt 4 / USB4 ports
- Four 10Gbps USB-A ports
- 150W total power
- Compact
Cons
- Sits away from Mac mini
- No extra storage capacity
Compatible with: Any USB-C/Thunderbolt computer
Size: 4.5 x 2.8 x 0.7 inches
Ports:
- 4x Thunderbolt 4 ports (40Gbps, 15W)
- 4x USB-A (10Gbps, 7.5W)
This super-compact Thunderbolt 4 hub differs from the OWC and Satechi hubs by being a different size and form to the Mac mini, and so it will sit outside of its footprint on your desk
It offers you seven fast ports—plus the upstream Thunderbolt 4 port that connects to your Mac mini—that will also ably charge connected devices.
If your Mac mini or Mac Studio has enough storage for your needs but not enough ports (step forward the more limited non-Pro M2 Mac mini), this excellent hub blesses you with multiple top-rated ports.

4. Alogic Clarity 27in UHD 4K Monitor
Pros
- 27-inch 4K 60Hz screen
- Excellent adjustable stand
- Extra ports
Cons
- Not 5K like the old 27-inch iMac’s screen
Ports:
- 1x USB-C (upstream)
- 1x USB-B (upstream)
- 2x USB-A ports (5Gbps)
- DisplayPort 1.4
- 2x HDMI 2.0
