How these two compare
Sequential throughput
Crucial P310 2230 1TB is rated 7100 MB/s read and 6000 MB/s write; Western Digital WD Blue SN5100 1TB, 7100 MB/s read and 6700 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.
NAND and warranty
NAND: Crucial P310 2230 1TB's NAND is not stated and Western Digital WD Blue SN5100 1TB uses QLC. 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 cover: Crucial P310 2230 1TB carries a 5-year warranty, Western Digital WD Blue SN5100 1TB does not state one. 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.
Which to buy
With a price missing for at least one side, there is no cost verdict to give. What separates two otherwise-similar drives is up in the sections above — sustained and random behaviour, whether there is a DRAM cache, the flash tier and the warranty — so weigh those against what your build needs.
