How these two compare

Sequential throughput

SanDisk Optimus GX 7100 4TB is rated 7000 MB/s read and 6700 MB/s write; TeamGroup MP44 4TB, 7000 MB/s read and 6000 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.

Endurance

The makers warrant 2400 TBW on SanDisk Optimus GX 7100 4TB and 2000 TBW on TeamGroup MP44 4TB — how much writing each is rated to take before the endurance clause lapses. Most desktop workloads never come close, so read the two against each other rather than as a limit you are likely to reach.

DRAM cache

SanDisk Optimus GX 7100 4TB is DRAM-less; TeamGroup MP44 4TB is DRAM-less. 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 and warranty

NAND: SanDisk Optimus GX 7100 4TB uses TLC and TeamGroup MP44 4TB's NAND is not stated. 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: SanDisk Optimus GX 7100 4TB carries a 5-year warranty, TeamGroup MP44 4TB 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.
