What to know before buying

The maker says operating systems may show approximately 7-10% less usable capacity than the labelled amount because of decimal versus binary capacity calculations.

Listing details to confirm

Speed claims are inconsistent: the title and specifications state up to 2100MB/s, while feature text also says up to 2000MB/s. Port-specific figures are stated as up to 2000MB/s for USB 3.2 Gen 2x2, 1000MB/s for USB 3.1 Gen 2x2 or USB 3.2 Gen 2, and 500MB/s for USB 3.0, 3.1 Gen 1 or 3.2 Gen 1. Another claim says USB-A reaches a maximum of 10Gbps. The listed USB 2.0/3.0 interface and speed descriptions do not align cleanly, so confirm the applicable port and speed for your device. The listing describes the drive as having both USB-C and an integrated USB-A adapter, while the supplied box inventory only lists a USB Type-A to Type-C adapter. Check the selected listing for the exact connector and package arrangement.

The supplied aggregate ratings are divided between five-star and one-star categories, with a mid-range overall score from a small sample. That is limited evidence rather than a clear consensus, and it does not explain the reasons behind ratings. Buyers should weigh this uncertainty alongside the listing's inconsistent speed claims and check that the drive suits their port and use case.
