Solid-state drives (SSDs) and hard disk drives (HHDs) both store data, but SSDs use semiconductor chips rather than a series of magnetic disks. The lack of moving parts can make SSDs more resistant to drops––though we still don’t recommend it. The technology is most commonly used in back-up and external storage, but manufacturers including Apple and Dell are also equipping laptops with SSDs in place of traditional hard drives. That’s because these devices are lighter, smaller, and faster than HHDs. They typically read and write data at around 550MB/s (megabytes per second) and 520MB/s, respectively, more than four times faster than the disk drives. Take note that this ultra-fast, super light tech is more expensive per gigabyte than its predecessor, too. But if you’re ready to take the plunge, here are some of the best SSDs to start with.
