[QUOTE="Randy B. Singer, post: 1945784, member: 190607"] 10Gbps is the rated speed for USB 3.1. The SK hynix Tube T31 SSD is a USB 3.2 device. Macs don't support USB 3.2; a USB 3.2 device attached to a Macintosh will run at USB 3.1 (10Gbps) speeds. Modern Macs support USB 3.1 via their Thunderbolt ports. Real world speed will likely be somewhat less, but otherwise there is no reason to be skeptical. Thunderbolt 3/4 = 40Gbps USB 4 = 40Gbps USB 3.2 = 20Gbps (Not supported by any Macintosh. A USB 3.2 device connected to a Macintosh will perform as a USB 3.1 device.) USB 3.1 = 10Gbps USB 3.0 = 5Gbps SK Hynix is a South Korean company that has variously been known as Samsung and Hyundai. Due to mergers of several semiconductor businesses, SK Hynix is simply a new name for an older more familiar company. It is one of the world's largest makers of semiconductors. They make memory for a bunch of big name computer companies. Their SSD's have been very highly rated.
