External or USB drives
Aren't they the same thing?
Well, technically yes, if you mean the way they connect to the 'host' or device using a USB connection, BUT, the way they store data is different.
USB Thumb drives, or sometimes called 'flash' drives refer to the way the data is stored. This is a rapidly changing environment, but the rule of thumb, (pardon the pun), is you use thumb drives up to 64GB and External 2.5" or 3", or SSD, (Solid State Drives) for larger amounts up to some ridiculous amounts....
OK, I'll answer before you ask;
💾Thumb drives, the 'James Bond' method of transferring data, uses 'flash' memory, which we won't bore you with the details, but is fabulous for smaller amounts of data in the short term, but can fail in the longer term and with multiple uses. Do take a bit of punishment though, after all the are generally kept in your pocket or handbag.
💾2.5" & 3" HDD, (hard drive disc), drives have physical metallic discs, sometimes in multiple layers that the 'head' read and writes too, similar to an old LP player. These drives are portable, but not designed to be moved around a lot, and don't handle being dropped well.
💾SSD, or solid state discs are the latest of the three technologies, and will in all likely hood, be the one that becomes commonplace, however being the cutting edge now means that they are more expensive, and do 'technically' have the same limited number of write/rewrite issues as flash drives, but technology is moving on and that is becoming less of an issue.
❗Be aware, all drives have common enemies. That is heat, moisture and impact. If you have your drives in direct sunlight, in a badly ventilated or damp place, this can reduce their life span, but by far the worst thing any drive can suffer is being dropped. Generally thumb drives will get away with it, but the circuits on HDD and SSD are fairly fragile, with HDD's especially vulnerable to damage to the physical disc, and the head
❗NEVER remove the drive before 'safely remove hardware' process is complete. The rewrite process may still be incomplete, and this can lead to corrupt and unreadable data. HDD's are particularly prone to failure in interrupted removal, as the 'head' may still be between discs, and if the disc falls on the head, it can damage both the disc and head, rendering the drive inoperable.
