How these two compare

Sequential throughput

ADATA XPG Mars 980 Blade 2TB is rated 14000 MB/s read and 12000 MB/s write; Crucial T705 2TB, 14500 MB/s read and 12700 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.

DRAM cache

the catalog does not state whether ADATA XPG Mars 980 Blade 2TB carries a DRAM cache; Crucial T705 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: ADATA XPG Mars 980 Blade 2TB uses TLC and Crucial T705 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: ADATA XPG Mars 980 Blade 2TB's controller is not stated, and Crucial T705 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: ADATA XPG Mars 980 Blade 2TB does not state one, Crucial T705 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.

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.
