8/26/2023 0 Comments Fast ssd driveLastly, to get a sense of how fast these USB 3.2 SSDs have become, we also threw the last generation of SATA-based USB SSDs into the mix. Likewise, if your PC only provides Gen 1 (5Gbps), those ports would also become a bottleneck when paired with any NVMe-based Gen 2×1 (10Gbps) portable SSDs. So, you might not be able to enjoy the performance boost of an SSD that supports the dual-lane USB 3.2 mode unless your PC comes with such a port. It’s worth emphasizing Gen 2×2 (20Gbps) ports aren’t commonly found on PCs. Hence, said SSD is classified as UFD, short for USB Flash Drive. Kingston XS2000, in contrast, employs Silicon Motion SM2320 single-chip USB 3.2 Gen 2×2 solution that eliminates a bridge controller to reduce cost and size. All the NVMe-based models are based on ASMedia ASM2362 USB-to-PCIe x2 bridge with support for USB 3.2 Gen 2×1 (10Gbps). They belong to either of the first two categories. Three types of drives based on NVMe-, SATA- and UFD-based SSDs were tested. Our test files comprised 40GB of MPEG-4 movies and 10GB of JPEG photos. The port being used supports Thunderbolt 3 with USB 3.2 Gen 2×1 (10Gbps) compatibility.

Feature ComparisonĪluminum metal alloy with plastic end caps In fact, it will be far easier to find a laptop with USB4 than one with USB 3.2 Gen 2×2 in a few years’ time since USB4 is already baked into Thunderbolt 4 and the latest AMD Ryzen powerhouse laptops also come with the latest variant of USB. You’re better off investing in a USB4 SSD if you are into future-proofing your equipment. But unless you are building your own rig, those ports are hard to come by. While USB 3.2 SSDs are predominantly Gen 2×1, a rare few come with a Gen 2×2 (20Gbps) interface. Nonetheless, the performance leap is still impressive. Our real-world benchmark shows the latest batch of USB 3.2 SSDs can handle heavy lifting with speeds of 700 to 800MB/s yet the external interface remains a bottleneck for PCIe Gen 3 NVMe drives. Since 2020, we’ve seen the inevitable shift to blazingly fast NVMe on mobile SSDs.Īs for 2022, nearly all shipping USB-based SSDs are now NVMe SSDs paired with a USB 3.2 Gen 2×1 to PCIe 3.0 x2 bridge chip. Industry-wide adoption of USB 3.2 Gen 2×1 (10Gbps) means SATA-class SSDs maxing out at 550MB/s can no longer catch up to USB. Kingston also is the most compact SSD of the pack and is capable of 20Gbps USB 3.2 Gen 2×2 connectivity provided you have a Type-C port that supports it. If you are fine with working within the limit of the SLC cache, both Crucial X8 and Kingston XS2000 offer better small file read performance than Sandisk Extreme V2. Additionally, it comes with 256-bit AES full-disk encryption and is backed by a generous five-year warranty. The drive outperformed the rest of the pack in our stress test when other SSDs didn’t fare so well after their respective SLC cache was saturated. Between these USB 3.2 SSDs, we have to pick Sandisk Extreme V2 for its exceptional performance consistency.
