How these two compare
Sequential throughput
Acer Predator GM7 512GB is rated 7200 MB/s read and 3800 MB/s write; ADATA XPG Gammix S70 Blade 512GB, 7200 MB/s read and 2600 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
Acer Predator GM7 512GB lists at £114.99, or £224.59 per TB; ADATA XPG Gammix S70 Blade 512GB at £102.59, or £200.37 per TB.
Endurance
The makers warrant 300 TBW on Acer Predator GM7 512GB and 370 TBW on ADATA XPG Gammix S70 Blade 512GB — 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
Acer Predator GM7 512GB is DRAM-less; ADATA XPG Gammix S70 Blade 512GB 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: Acer Predator GM7 512GB uses TLC and ADATA XPG Gammix S70 Blade 512GB 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: Acer Predator GM7 512GB uses the Maxio MAP1602, and ADATA XPG Gammix S70 Blade 512GB uses the InnoGrit IG5236. 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: Acer Predator GM7 512GB carries a 5-year warranty, ADATA XPG Gammix S70 Blade 512GB 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.
