Samsung’s PM1643a, a three-year old enterprise solid state drive with a SAS interface remains the largest 2.5-inch SSD to date with a capacity of 30.72TB (or six of the above WD Elements Portable). Time is the only resource that cannot be replenished, and an external SSD saves professionals plenty of time when working on large files that have to be transferred back and forth from a laptop or PC.Laptop SSDs take the shape of 2.5-inch slabs or M.2 bars. This includes video editors, production artists, music engineers, and more. Even students who have to turn in an important project may want to consider one of these drives.Īdditionally, people who need to work on large files in the field will appreciate the speed and performance of external SSDs. Influential business people who have to travel with important documents or presentations will definitely benefit from an external SSD.
This doesn’t necessarily limit use cases to top-secret government operations. Who Should Buy an External SSD?Īnyone working with mission-critical data that needs to be transported should definitely invest in an external SSD. Finally, since the external drive will most likely travel with the owner, there is less chance of data loss or corruption with SSDs because there are no moving parts that can be jostled during transit. In general, SSDs have a much higher mean time between failures (MTBF) than mechanical HDDs. Once again, because the external solid state drive has no moving parts, there is less wear and tear and fewer internal components to fail. An external SSD has no moving parts, unlike the mechanical HDD, which has to wait for platters to spin up and down when reading and writing data. Just as an internal SSD outperforms an internal HDD due to how each type of drive is constructed, the same logic follows for their external counterparts. There are two main differences between an external SSD and an external HDD. Both can easily back up the data from a PC or laptop. Both offer more storage space than USB flash drives. When it comes to the main purposes of an external drive, whether it be a mechanical drive or a solid state drive, both categories satisfy similarly. Just a few years ago, internal SSD hard drives were so expensive that external SSD hard drives were out of the question. However, the prices for SSDs are continually falling year over year, almost reaching parity with their mechanical counterparts in some cases. Solid state drives (SSD) are a relatively new technology, which makes SSDs more expensive than traditional mechanical hard drives.
