Cons
Runs hot enough that the heatsink is not optional
Comment
Everything about this drive is right except one thing, and it is a thing you can plan around rather than a fault. It gets hot. Not dangerously, not enough to throttle with a heatsink over it, but if your only free M.2 slot is the one squeezed under the graphics card then buy the heatsink at the same time as the drive rather than a week later like I did.
Leo L. Used for: More than a year
Pros
No regrets at all about buying the biggest one
Comment
Expensive, worth it, and a year and a half later I have not once wished I had saved the money by going smaller. Still the best part of the build!
Henry A. Used for: 3–6 months
Pros
The last storage decision the console will need
Comment
Put this in a PS5 and it is the last storage decision I will need to make for that console. Four terabytes takes everything I own with room for the next few years of releases. It passed the console's speed test comfortably and with a decent heatsink on it the console has never flagged a temperature!
Theo W. Used for: 6–12 months
Pros
Big enough that you stop thinking about capacity
Comment
The 4TB version is the one to get if you can stomach it, because the smaller drives fill up and then you are back here buying another one. Mine holds Windows, every game I own and the photo library, and it is still half empty. Ten months in the wear indicator has not moved off one per cent!
Oliver R. Used for: More than a year
Comment
Bought this when the 2TB in the same machine filled up for the second time, and the lesson I took from that is to buy the bigger drive first. A year and a bit later it is about two thirds full and I have stopped thinking about what to uninstall, which is worth more than any benchmark. The drive itself performs exactly as the smaller one did, holds its speed through large copies, and sits at 46 degrees under the board heatsink.
Louie S. Used for: 3–6 months
Comment
Went into a machine used for architectural visualisation where scene files run to tens of gigabytes each. Opening one used to be a walk to the kettle, now it is a pause. The four terabytes means an entire project archive sits locally rather than on the network, which has changed how the whole day goes
Isla D. Used for: 3–6 months
Pros
The card reader is now the slow part, not the drive
Comment
Bought for a machine that ingests drone footage all day, where the limiting factor used to be how fast the card reader could empty onto the disk. Now the card reader is comfortably the bottleneck and the drive never breaks a sweat. A full 256GB card empties in about four minutes, which is the reader's limit rather than the drive's. Four terabytes means a whole shoot fits without archiving anything mid-job, and that alone justified the outlay!
Willow L. Used for: 6–12 months
Pros
Everything finally lives on one drive
Cons
Warm enough in the second slot to need a heatsink
Comment
Four terabytes meant everything finally lives on one drive, no more juggling which games get installed. It does run warm in the second slot though, and I ended up buying a heatsink for it.
Harry R. Used for: 1–3 months
Pros
Held above 1.2GB/s through a two terabyte copy
Cons
Priced like the flagship it is
Comment
Second Samsung drive in this machine and it behaves exactly like the first, which is what you want. Copied two terabytes of games onto it in one go and the speed held above 1.2GB/s the whole way, which surprised me!
