The Acer Predator GM7 is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Acer Predator GM7 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the MAP1602A Falcon Lite from MaxioTech, a DRAM cache is not available. Acer has installed 128-layer TLC NAND flash on the Predator GM7, the flash chips are made by YMTC. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Predator GM7 is rated for sequential read speeds of up to 7,400 MB/s and 6,300 MB/s write.
At its launch, the SSD was priced at 160 USD. Acer guarantees an endurance rating of 1200 TBW, a very low value compared to other SSDs.

Notes

Controller:

This controller features multiples variants:
F1C - Uses NVMe 1.4
F2C - Uses NVMe 1.4
F3C - Uses NVMe 2.0
F3C U - For 4TB SSDs and uses NVMe 2.0

NAND Die:

Array Eficiency of over 92%
Xtacking 3.0 introduces back side source connect (BSSC) for memory cell wafer, which leads to simpler process and lower cost
This layout has a 2x 2 Plane layout
It achieves 26µs in read latencies in pSLC Mode, and also 180 µs in tPROG in pSLC Mode.
