That’s middle-of-the-road for a USB 2.0 device, where the fastest can manage about 25MBps reading and 10MBps writing data. (On this benchmark, MBps means one million bytes per second.)

You very helpfully ran CrystalDiskMark when I asked, and it put the read speed at 16.28MBps and the write speed at 6.52MBps. If your 1TB Flash drive reliably holds 1TB for a year or two, then it’s unlikely to be fast. As mentioned in the comments below, this is almost certainly a scam, because the old computer industry adage still applies: “cheap, fast, good – choose any two”. I was surprised – shocked! – to discover that you could buy a 1TB flash drive for less than a tenner, because I’ve been paying more than that for 16GB and 32GB versions. Could you use one of those as a normal day-to-day drive? I will use one as a backup, but if I mirror my drive on it, could I switch over to it if my drive goes down again? Roger I have just had to replace my 1TB hard drive, which cost £25 all done and dusted, but I notice you can now get a 1TB USB Flash drive for £8.99.
