How these two compare
Sequential throughput
Crucial P510 2TB is rated 14000 MB/s read and 11000 MB/s write; Sabrent Rocket 5 2TB, 14000 MB/s read and 12000 MB/s write. These are peak sequential rates over PCIe — the speed you would see copying one large file. For boot, app launches and everyday feel, random access matters more than this headline figure.
Price
Crucial P510 2TB lists at $339.00, or $169.50 per TB; Sabrent Rocket 5 2TB at $349.99, or $175.00 per TB.
DRAM cache
the catalog does not state whether Crucial P510 2TB carries a DRAM cache; Sabrent Rocket 5 2TB carries a DRAM cache. A DRAM cache holds the drive's mapping table — the index of where each block physically sits — so the controller places and finds data without an extra flash lookup. A DRAM-less drive borrows a little system memory (HMB) or a slice of its own flash instead, and is likelier to slow once a long run of random writes outlasts its fast cache.
NAND, controller and warranty
NAND: Crucial P510 2TB uses TLC and Sabrent Rocket 5 2TB uses TLC. The tier is bits per cell — SLC, MLC, TLC and QLC from one to four — trading density against endurance and sustained-write speed: QLC is cheapest per gigabyte, TLC the mainstream balance, and the denser the cell the sooner sustained writes taper. On the controller: Crucial P510 2TB's controller is not stated, and Sabrent Rocket 5 2TB uses the Phison PS5026-E26. It is the chip handling error correction, wear-levelling and where each write lands — much of how a drive holds up under load — even if the part number on its own tells you little. On the cover: Crucial P510 2TB does not state one, Sabrent Rocket 5 2TB carries a 5-year warranty. The length is the maker's own vote of confidence, and on an SSD it tends to track the endurance rating — a longer warranty usually meaning more rated writes.
