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.
Price
SanDisk Optimus GX 7100 4TB lists at $1,052.99, or $263.25 per TB; TeamGroup MP44 4TB at $719.99, or $180.00 per TB.
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.
