Is the 990 EVO Plus worth it over the 990 Pro?

For games and daily use, yes; it is close in real-world speed. The 990 Pro holds up better under heavy sustained writes and suits workstation loads.

Yes. The single-sided M.2 2280 design fits the PS5 slot, though Sony requires a heatsink for the console.

Is it DRAM-less, and does that matter?

It has no DRAM cache and uses host memory instead. Everyday tasks are fine; very large continuous writes slow down sooner than on DRAM drives.

It is a PCIe 4.0 x4 drive and works in PCIe 3.0 slots at lower speed. PCIe 5.0 boards run it at 4.0 speed.

No. The drive is bare, so add a heatsink if your board or console needs one.

It supports hardware encryption, so you can enable drive-level protection with compatible software.
