The only one I'm aware of is a Samsung SSD but it'll set you back a grand.
Does the storage have to be internal?
I have this... much prefer it over mechanical... game drive mostly... it's not just the speed improvement... it's the lack of noise - making my PC bordering on silent
It might have to be if it has to be 2.5" and not seagate or SAS.
Something like a wd my cloud is quite useful. you can stick it anywhere so you don't have to hear it and it stays on all the time so no one gets interrupted because of a reboot.
The only 4tb 2.5" available afaik is the "Seagate BarraCuda 4 TB 2.5", but even that's not really suitable for anything as it's 15mm height, so won't fit in a standard 2.5" bay
