Adata has finally launched the SE920, the company's first USB4 external SSD. We first heard about the Adata SE920 over two years ago, but it's only now coming to market, with slightly reduced specs. It boasts transfer speeds up to 3,800 MB/s, which means the SE920 rivals even the best external SSDs currently on the market. Naturally, you'll need a modern PC or laptop with the appropriate connector(s) to take advantage of the potential transfer rates.
The SE920 has the latest USB4 (40 Gbps) Type-C interface to deliver blazing-fast performance. The interface is backward compatible with USB 3.2 and USB 2.0 ports, though the latter would seriously limit throughput. Thunderbolt 3 and 4 support is also on the table; however, you'll want to pair the SE920 with a USB4 Type-C port to unleash the drive's full potential. The Adata SE920 is, at least on paper, one of the fastest external SSDs around. It's up to 40% faster than the Sabrent Rocket Nano XTRM, which is already pretty speedy for file tranfers.
The SE920 comes in 1TB and 2TB flavors, providing a decent amount of capacity. Adata doesn't specify what SSD controller powers the SE920 nor the type of NAND that's inside the drive, which is unfortunate. Lack of such details suggests the manufacturer could change hardware in the future, should it deem in practical to do so.
The SE920 offers sequential read and write speeds up to 3,800 MB/s and 3,700 MB/s, respectively. In real-world usage, we're looking at around three seconds to transfer a 4K video file that's 10GB in size. It's important to highlight that the SE920's sequential write performance is restricted to 3,200 MB/s on the Thunderbolt 4 interface.
