That didn’t make enough difference to catch on, but you could give it a whirl.
HOW TO SETUP USB RAM STICKS PC
A decade ago, it introduced ReadyBoost, to increase PC performance. Microsoft has tried a few ways to exploit USB Flash drives. What you need is something like Windows To Go…. At best, it might help you to get up and running after you replaced the failed hard drive, but so would keeping a back-up on an external hard drive.
HOW TO SETUP USB RAM STICKS CODE
However, I wouldn’t expect it to work if the hard drive failed, because all the code will still refer to the C: drive. You can certainly mirror your existing 1TB hard drive to a 1TB Flash drive. When Windows To Go appeared with Windows 8, Microsoft finally provided a supported way to run Windows from a USB memory stick. You can get 3TB external hard drives – with 12 times more storage space – for similar prices. Even 256GB flash drives often cost in excess of £70, and can cost far more than that. Unfortunately, that would increase the cost dramatically. Obviously, it would be better to use a USB 3.0 flash drive, which can read data at 100MBps or more. Speed does make a difference to usability, which is why people are moving to SSDs (~5x faster than HDDs) and M.2 drives (~25x faster than HDDs). It’s a lot slower than your 1TB hard drive (88.80/82.08), which is somewhat slower than mine (127.7/122.6). 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.
