How these two compare
Sequential throughput
Kioxia Exceria Pro G2 1TB is rated 14400 MB/s read and 12700 MB/s write; Samsung 9100 Pro 1TB, 14800 MB/s read and 13400 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
Kioxia Exceria Pro G2 1TB lists at 156,99 €, or 156,99 € per TB; Samsung 9100 Pro 1TB at 229,00 €, or 229,00 € per TB.
DRAM cache
Kioxia Exceria Pro G2 1TB carries a DRAM cache; the catalog does not state whether Samsung 9100 Pro 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, controller and warranty
NAND: Kioxia Exceria Pro G2 1TB uses TLC and Samsung 9100 Pro 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. On the controller: Kioxia Exceria Pro G2 1TB uses the Silicon Motion SM2508, and Samsung 9100 Pro 1TB's controller is not stated. 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: Kioxia Exceria Pro G2 1TB carries a 5-year warranty, Samsung 9100 Pro 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.
