PlayStation 5’s firmware update 2.0 is coming soon and it’s set to deliver some key changes to the system’s capabilities: a new UI that separates PS4 and PS5 apps, along with 3D audio for TV speakers – but the big draw is support for the PS5’s internal M.2 SSD port, opening the door to a meaningful expansion of system storage, where we’ve been limited to just 667 gigs of usable space since launch. We’ve tested attachable USB storage solutions before and found them to be an excellent way to run PS4 titles under back-compat, but this is the real deal – this is the way forward for hosting more of our PS5 games on ultra high-speed storage.
Thanks to early beta access courtesy of Sony, we were able to complete some initial testing for this piece. We used a Samsung 980 Pro SSD – the 500GB model in this case, though these results should apply to large capacity 1TB and 2TB variants too. We actually bought this SSD when the PS5 launched specifically for this use-case as it met Mark Cerny’s specs for NVMe drives laid out last year, and with 6500MB/s bandwidth, it exceeds Sony’s spec of a 5500MB/s minimum. It’s also a PCI Express Gen 4 model – another essential spec point. The only thing we needed to add was a heatsink, though you can run ‘naked’ if you like. We used a spare Gigabyte Auros heatsink we had to hand, but very cheap equivalents from Amazon are available that’ll get the job done.
This is a fairly easy upgrade, but to be clear, it’s a far cry from the plug and play Seagate Storage Card solution favoured by Microsoft for Xbox Series consoles. Even so, expanding PS5 storage shouldn’t take more than 10 minutes. Step one is to pull away the PS5’s white outer casing, specifically the right-side ‘wing’ when viewed head-on. The top two corners need a gentle pull upwards, and from there, you simply slide the casing down across the PS5’s body. You’ll hear a click.
Next, you open up the expansion bay. A small Phillips crosshead screwdriver does the job here, revealing the M.2 SSD enclosure. Once inside this, you’ll need to remove the screw and spacer. Make note of the length of your chosen M.2 SSD, and plant the spacer at the relevant point in the bay. Installation of the SSD itself is a simple matter of sliding the heatsink-equipped SSD into the metal contacts at the bottom. Again, you’ll hear a click. Place the SSD onto the spacer, tighten with the screw, reattach the expansion bay cover and then put the PS5 back together. Now we’re good to go.
Booting the PS5 for the first time offers a quick setup. First, you format the SSD, and then you’re greeted with a read speed test – the 980 Pro rated at 6500MB/s. Moving to the PS5’s storage menu, there’s some good news here as well. The M.2 SSD appears as it should here – but you can also use an external USB-based HDD alongside it. Add that to the PS5 internal drive and you have three drives to juggle data between in total – but remember you can only boot games from the internal drive or your freshly installed NVMe storage. Also useful is a new toggle to choose which SSD you want as your default install drive for games. Beyond that it’s all very straightforward. The only glaring omission, as ever on PlayStation consoles to date, is the ability to copy games between drives. Right now, you can only transfer data in a cut-paste fashion.
The first test in putting our upgrade through its paces? Ratchet and Clank: Rift Apart – a game literally built around Sony’s high bandwidth SSD solution. The rapid speed of PS5’s internal drive gives birth to a new mechanic, letting Ratchet instantly travel between worlds using portals. Developer Insomniac makes a showcase of PS5’s SSD tech from the first level: new assets stream in rapidly as Ratchet is taken on an on-rails tour of different planets. It flows beautifully on PS5’s internal drive, though it’s not faultless. Look close and you’ll see streaming stutters as Ratchet careens through each portal, brief hiccups in the sequence that disrupt an otherwise tight lock in its performance RT mode. It’s not a deal-breaker, but the chances are that if we’re looking at a storage bottleneck, continuously switching between multiple worlds loaded on the fly is a likely candidate.
So to the comparison between the PS5 internal and our M.2 SSD. Testing each in our above video, performance looks to be essentially identical. In most cases it’s actually an exact match between the two SSD solutions when it comes to the mentioned in-game stutter. Jumping portals triggers the same hitches, and always in the exact same moments – though with one instance where the M.2 is less severe in its drop that may be an outlier result. In all other respects, the 980 Pro performs in a similar manner to the existing storage solution, with equally flawless gameplay. As first impressions go, this is a strong start.
Loading times are up next. We split this into two banks of tests: PS4 titles running under backwards compatibility and true, PS5 native games. There’s one thing to stress before we go on: for whatever reason, there can be a variance between loading times run to run, so there may be some outlier results. However, across all of our tests here, a trend is clear: using the Samsung 980 Pro in the expansion bay, loading times are generally better than they are on the internal drive and there seems to be an advantage in adding a heatsink to the NVMe SSD too, albeit slight. The exception to the rule is Battlefield 5, which consistently saw the internal SSD beat external options.

The next set of tests concentrate on PlayStation 5 native apps – and in this regard, everything just works as we would hope and expect it to. Every test we carried out saw the external drive produce results that are near-identical to Sony’s integrated custom SSD. There may be more variance in drives that barely meet the spec, while there are some PCIe Gen 4 drives that significantly fall south of Sony’s bandwidth requirement. Not only that, but Sony says that even drives that meet the 5500MB/s bandwidth requirement may see degradation in game performance. We would strongly urge users to go with drives with 7000MB/s bandwidth all this considered, which was Mark Cerny’s recommendation last year.
The only other takeaway we have concerns PlayStation 4 titles. Yes, the external M.2 option does generally seem to be faster than running from the native drive. However, we observed similar behaviour when PS4 games were loaded from SSDs attached via USB. If you’re looking to optimise storage allocation, it may make sense to keep your PS5 titles on the internal drive and the NVMe expansion, but utilise a cheaper SATA to USB-based solution for PS4 games.

Our final tests were all about raw transfer speeds, where moving games between PS5’s stock drive and the M.2 expansion is a perfect case study. Picking Cyberpunk 2077 gives us a meaty 101GB install to shuttle between these two drives. After extensive testing, it became clear that writing to the M.2 drive…
