How these two compare
Sequential throughput
Corsair MP700 1TB is rated 10000 MB/s read and 8500 MB/s write; PNY CS2150 1TB, 10200 MB/s read and 8500 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
Corsair MP700 1TB lists at $399.99, or $399.99 per TB; PNY CS2150 1TB at $299.99, or $299.99 per TB.
DRAM cache
Corsair MP700 1TB carries a DRAM cache; the catalog does not state whether PNY CS2150 1TB 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
NAND: Corsair MP700 1TB uses TLC and PNY CS2150 1TB 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.
Which to buy
PNY CS2150 1TB. It gives up nothing to the other on the measures the site tracks and leads on at least one, so there is no trade to weigh — the sections above show where the margin is.
