Cooke... sigh. You are using the wrong words to describe stuff. There are USB Flash drives (aka Flash drive, aka thumb drives) that is what you just bought. There is a such thing as a External SSD, that is not what you shown. These are External SSDs.
When I saying 'SSD', I am referring to internal storage solid state drives (SSD). they been around for a decade, they are inside modern day computers, and come in a variety of types:
2.5" SATA SSD (I pictured in the earlier post)
M.2 SATA SSD (pictured here)
M.2 NVMe SSD. (pictured here)
Furthermore, USB Flash Drive have been around for at least 2 decades, it has a variety of types (Type A, B, Mini, Micro, C) which have gone through several generation (see list below).
Each new USB gen brought improved read/write speed, power delivery, etc that (I'm bolding this because this is the most critical part) are only achieved if you match the USB gen type with a computer (desktop/laptop) that has the same rated USB ports of that generation, otherwise your USB Flash drive will run at the reduced speed of the port or may malfunction if it requires the higher power delivery provided from newer USB gen ports (although this usually the case with other USB external devices not typically USB Flash drives, those will just run slower).
Again. The link you posted of your purchase is a USB Flash Drive. A USB 3.1 type drive, which is the most current USB gen for type A and should deliver up to 10GBps (1250Mbps) speed again PROVIDED IF your computer has a USB 3.1 rated port. Below are USB speeds by generations.
USB 1.0 (1.5 Mbps)
USB 1.1 (12 Mbps)
USB 2.0 (480 Mbps)
USB 3.0 (5 Gbps / 625 Mbps)
USB 3.1 (10 Gbps / 1250Mbps)
Solid State Drives have also gone through several generations as well, improving with faster speeds.
SATA I (1.5Gbps / 187.5Mbps)
SATA II (3Gbps / 375Mbps)
SATA III (6Gbps / 750Mbps)
M.2 SATA (6Gbps / 750Mbps)
M.2 NVMe gen3 (28Gbps / 3500Mbps)
M.2 NVMe gen4 (40Gbps / 5000Mbps)
