By contrast, if you jolt an SSD while you're reading or writing data, there is no risk that your files will become corrupted and unreadable. If you drop the drive, you could damage the interior mechanism and make your data inaccessible. But the same tech that makes hard drives a tantalizing value becomes their biggest liability when used on the go. Since hard drives are mechanical devices that use mature technology, you can get relatively large amounts of storage capacity for the money. These are similar to the silicon that makes up a computer's RAM, but they retain your data when electrical power is cut off.
