Adata, OWC, and Stardom Roll Out USB4 SSDs and Enclosures for Quicker Exterior Storage
When the USB4 specification emerged a number of years in the past, it was rapidly positioned as a inexpensive different to the Thunderbolt 3 expertise which dominated the market of high-performance direct-attached storage (DAS) units and docking stations. Since then, we have seen a number of USB4 docks hit the market, however USB4 DASes and SSDs are nonetheless uncommon. Fortunately, the scenario started to vary within the latest weeks, as a number of distributors have lastly begun releasing their very own USB4 SSDs and exterior drive enclosures.
Adata

Adata’s SE920 Exterior SSDs provide capacities of 1 TB or 2 TB, together with a sequential learn pace ranking of as much as 3.8 GB/s in addition to a sequential write pace of as much as 3.7 GB/s when working with a USB4 host. In any other case, the drive is rated for 3.20 GB/s on Thunderbolt hosts, because of the larger overhead of the Thunderbolt protocol.
One attention-grabbing function of the Adata SE920 Exterior USB4 SSD is that it comes with a ‘telescoping’ case that permits to activate its inside fan for higher warmth dissipation. Such design permits to higher guarantee constant efficiency beneath excessive hundreds, which is ready to be significantly helpful when transferring massive volumes of information. In the meantime, like different fashionable SSDs, the SE920 makes use of pseudo-SLC caching, which signifies that it demonstrates its most efficiency solely whereas there may be spare SLC-cache.
Adata’s drive appears to be like like a really first rate product total, and it is priced very competitively with different high-performance drives available on the market, with Adata charging round $150 for the 1 TB model and $200 for the two TB model.
OWC
In the meantime, for the DIY crowd that desires to construct their very own USB4 SSDs, standalone USB4 enclosures are lastly obtainable as nicely. OWC’s Express 1M2 enclosure is predicated on the ASMedia ASM2464PD USB4/Thunderbolt to NVMe bridge, and is suitable with nearly any NVMe M.2-2280 SSD.
The enclosure helps sequential learn/write speeds of as much as 3,151 MB/s, in addition to capacities as much as 8 TB (the biggest M.2 2280 drive capability at the moment obtainable). Aware of how heat fashionable, high-end SSDs can get, the enclosure’s case acts like an enormous warmth sink, serving to to maintain these more and more toasty SSDs cool.
On paper, OWC’s Specific 1M2 DIY enclosure doesn’t attain speeds fairly as excessive as Adata’s SE920 SSD, so the additional capability and skill to throw in any M.2 SSD you will have mendacity round are the primary promoting factors of the machine. Pricing, then again is a better hurdle; OWC is charging $119.99 for the Specific 1M2 enclosure by itself, and $219.99 for the enclosure with pre-installed 1 TB SSD.

Stardom additionally has its UBOX-B4BP USB4 SSD enclosure that has the identical function set (e.g., compatibility with nearly any M.2-2280 SSD and newest PCs), however it’s barely bigger and its rated efficiency figures are as much as 2,920 MB/s for writes and as much as 3,214 MB/s for reads.
The enclosure permits constructing exterior USB4 storage options of as much as 8 TB (and bigger when such drives grow to be obtainable) that may work with each new and previous PCs. Curiously, Stardom has included a second USB-C connector on the enclosure solely for energy functions, permitting it for use with an exterior energy adapter if a bunch cannot present sufficient bus energy by itself.
Stardom but has to start out promoting its its UBOX-B4BP USB4 SSD enclosure within the U.S. and Europe, however in Taiwan the product prices NT$3,990 ($120 with out VAT), which isn’t precisely low cost.
