Acer is launching its high-end 2 TB PCIe4 x4 NVMe SSD this week under the Predator GM7000 family. These 3D TLC drives each use an Innogrid Rainier IG5236 controller designed specifically for the PCIe x4 inteface fo sequential read and write speeds of up to 7.4 GB/s and 6.4 GB/s, respectively, which is exactly what the 2 TB GM7000 can offer.
Additional specifications on the GM7000 series can be found on its official product page here.

Our host PC is the Intel NUC11PAQi7 mini PC which fully supports PCIe4 x4 SSDs like our GM7000. Acer has also provided for us an aluminum heat sink which is currently sold separately from the drive, but it may come as a bundle in the future. The drive itself has a built-in graphene foam pad with adhesive on top for applying the heat sink.

CrystalDiskMark shows a top read rate of about 6700 MB/s against the advertised 7400 MB/s. Write rates in particular are more disappointing at only 4000 MB/s. Reading and writing of very small 4K block sizes are slower than expected as well with results that are significantly slower than what we’ve seen from other PCIe4 SSDs like the Samsung PM9A1.
* … smaller is better
ATTO results confirm the relatively slow performance at very small I/O sizes. At 1 KB, its performance is only about half that of the PCIe3 Asura Genesis Xtreme or HP EX950. Users aren’t getting the full performance of the drive until reaching at least 4 MB.
We ran the DiskSpeed read loop test continuously to check for maximum temperature with the heat sink installed. At its peak, the drive would reach 85 C which is just 10 C shy from the critical temperature threshold of the model. Most users will not be transferring large files for such long periods, however, but a well-ventilated chassis is definitely recommended to keep temperatures in check.
The heat sink itself can become very hot at over 65 C when the drive is under load. We suspect that removing the graphene foam pad and replacing it with double-sided sticky thermal pads may actually improve the effectiveness of the heat sink even though this would be against the printed instructions.
Though transfer rates on the Predator GM7000 are faster than any PCIe3 SSD when dealing with larger file sizes, performance can be slower when dealing with smaller 4K or 4K-64 clusters. The Samsung PM9A1 is still the faster PCIe4 drive assuming you can find one available. At $349 USD for our 2 TB option, the Acer drive does come a bit cheaper than the 2 TB Samsung 980 Pro or 2 TB Seagate FireCuda 530 at the moment albeit it will entail somewhat slower performance.
Availability is currently limited through major retailers like Amazon at the time of writing. The 512 GB, 1 TB, and 2 TB capacities have an MSRP of $119, $179, and $349 USD, respectively, without the heat sink.
