  • What is a SATA SSD and how does it work?

  • What is a SATA SSD? SATA SSDs look like laptop hard drives, flat and rectangular like the Samsung pictured above. They are the lowest grade SSD and use the same interface as hard drives. However, a PC that uses a SATA SSD has three to four times the bandwidth (how much data it can read/write simultaneously) than a PC using a hard drive.

  • What is the difference between HDD and SSD?

  • Compared to the traditional method of HDD storage, which is short for hard-disk drive, SSD drives are built without the traditional spinning disk drive and movable hard disk heads used for reading and writing new information to the disk.

  • Can I put an SSD drive in a laptop?

  • This design is to allow the SSD drive to put in a laptop or desktop computer in place of a hard drive. To do this, it needs to have the standard dimension as a 1.8, 2.5 or 3.5-inch hard drive. It also uses the common SATA interface so that it can easily be placed into any PC as a hard drive would.
