ADATA USB4 Portable SSD Can Give Some M.2 Drives a Run for their Money

[btarunr]

ADATA SE920 is the company's first portable SSD to take advantage of USB4 and offer transfer-speeds that utilize that added interface bandwidth. The drive features a 40 Gbps USB4 interface, with a single cable handling both power and host connectivity. Internally, this is an M.2 PCIe Gen 4 SSD that's been wired to an ASMedia ASM2464PD chip that converts a 40 Gbps USB4 uplink to a PCI-Express 4.0 x4 downlink, and hence the internal drive has slightly more bandwidth than PCI-Express 3.0 x4 (32 Gbps).

The ADATA SE920 comes in capacity variants of 1 TB and 2 TB. Both variants offer sequential transfer rates of up to 3800 MB/s reads, with up to 3200 MB/s writes. The brushed aluminium enclosure has a mechanism that slides out a diagonal insert with air vents for an active cooling mechanism inside, which cools the internal drive, the bridge chip, and some power components. A USB4 type-C to type-C cable is included with the drive.

There are only a couple new boards with USB4 support.


so far.

Can you name 1 board with the full 40Gbs USB4 functionality? Even the most expensive X670/Z790 boards come with JHL8540 controller, which is basically TB4. Even though it is compliant with USB4, internally it is PCIe 3.0 x4, not PCIe 4.0 x4. The label "USB4 Compliant" means you can connect USB4 drive to it and it will work, but surprise surprise: the max data transfer speed will be 10Gbs only, not 40Gbs. If you connect TB4 drive to it, max data transfer speed will be 32Gbs, with real speed around 22-24Gbs after deducting the necessary overhead. In my opinion this is a huge marketing scam on consumers since I do believe only small percentage of consumers know about these important details.

Bottom line: What PC you can connect this new ADATA SE920 drive to in order to fully utilize its USB4 speeds??
