(One factor is spin rate-among external drives, 5,400rpm units are more common and more affordable than 7,200rpm.)
Just how much faster is it to read data from flash cells than from particular points on spinning platters? Typical throughput for consumer hard drives is in the range of 100MBps to 200MBps. 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.Īnd, again, hard drives are slower because they have to physically access your data. 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 huge 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. Unlike a hard drive, which stores data on spinning platters accessed by a moving magnetic head, a solid-state drive uses a collection of "persistent" flash memory cells to save data.
