I wanted to talk about this last week, but everything got ahead of me.
So fairly recently, I upgraded my PS5 M.2’s SSD with a larger sized one. Now, I didn’t pay the absurd ‘AI inflation’ price for it, but this adventure may have been why. So, I’m telling this tale to help out anyone that gets into this predicament while installing a new SSD into their PS5.
Initially I placed the new SSD, a Samsung EVO Pro 990 with Heatsink, formatted it like the PS5 wanted, and was greeted with a ‘to slow’ error. The benchmark the PS5 placed it at was ~3307mbps, which was oddly slow. After some research, it appeared I needed to upgrade the firmware to fix this issue. My first thought was to just used an external USB adaptor, but come to find out, one cannot do that since it masks what the SSD actually is. Okay, so the next thing was PCIe to M.2 adapter; which I didn’t own. Finally the last option was to just place it into an open M.2 slot on a PC motherboard with one available – this is what I ended up doing.
I didn’t think I had an available slot on my newest PC, but apparently this board has a bonkers 3 slots for M.2’s to pick from and two of them are easily accessible. So, I turned off the PSU, and installed the new SSD into said slot, booted up, installed Samsung Magician, and it noticed it immediately stating it needed new firmware.
Perfect, I let it update the firmware, force shut down the PC per the software’s request, and then decided to reformat the SSD so Windows could see it and I could test it. The tests came back beautiful, and I shut it all down to put it back into the PS5. Now, during all that, I did boot up the PS5 with no SSD so it would rebuild the database noting it did not have one installed (supposedly this is to keep the PS5 from not booting). All those steps being done, it booted up and formatted it like before, but this time the speed jumped up to a whopping ~6608mbps – perfect!
What about the old one? I did the whole process over again, but this time formatted it as exFat to use as external storage for PS4 games, and that worked out great/a lot easier.
So, if anyone out there has an issue with a new Samsung EVO 990 with heatsink; plop it into your PC – whether with a PCIe or on the motherboard directly, run Samsung Magician, and hopefully y’all should be good to go! Just, probably do all this before trying it the first time to save some extra hoops and loops to jump through.
