Regardless of the flurry of PCIe 5.0 SSDs on show, Acer licensee Biwin Expertise had some of the attention-grabbing drives at CES 2023: The Acer Predator GM7 SSD armed with flash from YMTC, a China-based NAND flash chipmaker caught up within the US-China commerce struggle. This flash maker is now on the US Entity Checklist, which means all imports and exports to the corporate should be reviewed and authorised by the US Commerce Division. Nonetheless, Biwin nonetheless hopes to deliver this new SSD to the US market — restrictions allowing, in fact.
YMTC could look like an obscure firm, however its revolutionary flash structure has attracted a number of the largest names within the business, together with Apple, which reportedly certified the flash to be used in its personal units and even helped it recruit workers. Given the brand new restrictions, Apple has reportedly put these plans on ice, however Biwin remains to be plowing ahead with its Acer-branded SSD.
The flash on the heart of the dispute is YMTC’s 128-layer Xtacking 3.0. This flash has a novel structure that is constructed by stacking two completely different wafers atop each other, with a decrease layer utilizing older course of node tech for the logic, whereas a prime layer makes use of a more moderen, denser course of node for the reminiscence array that truly shops the info. This design affords all types of efficiency and price benefits, all of which make it a promising tech that poses a severe menace to the entrenched flash makers like Micron, Toshiba, and Samsung, all of whom use what we’d think about extra conventional designs. So naturally, it is rational to imagine that the brand new sanctions blunt the menace.
Biwin receives wafers of this flash and packages itself within the US, thus creating the flash packages we will see on the drive above. The flash operates at 2,400 MT/s, and the utmost energy consumption for the single-sided M.2-2280 drive weighs in at 5.67W.
The drive is powered by the Maxiotek MAP1602 DRAM-less SSD controller, which can also be designed in China. This controller makes use of Host Reminiscence Buffer (HMB) tech and connects by way of the PCIe 4.0 x4 interface with the NVMe 1.4 protocol.

The 2TB Acer Predator GM7 is formally rated for as much as 7,200 / 6,300 MB of sequential learn/write throughput and 1 million random learn/write IOPS. The corporate hasn’t shared endurance rankings but, however the drive does include a five-year guarantee. The drives will are available in capacities of 512 GB ($50), 1 TB ($90), and a couple of TB ($160).
Biwin demoed the 1TB drive at its suite at CES, and right here we will see the SSD peaking at 5,671 / 4,960 MB/s of sequential learn/write throughput. The drive additionally delivers 688,350 / 795,513 random learn/write IOPS in these checks. After all these checks are in all probability with a recent drive, so you may have to attend for our evaluation to see how efficiency shakes out.
Pending regulatory approvals, Biwin nonetheless hopes to deliver these drives to the US market however does not have a agency timeline for availability but. The corporate may even make the drives out there in different markets which may not be impacted by the sanctions.
