Frequently Asked Questions (FAQs)
1. What is a solid state SATA drive?
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.
2. Is SATA as good as SSD?
SATA drives are less expensive and more common than SSDs. However, SATA drives are also slower to boot up and slower in retrieving data than SSDs. If you're looking for a hard drive with tons of storage space, a SATA drive may be for you, as they commonly hold terabytes of data.
3. What is internal solid state drive?
Stands for "Solid State Drive." An SSD is a type of mass storage device similar to a hard disk drive (HDD). It supports reading and writing data and maintains stored data in a permanent state even without power. Internal SSDs connect to a computer like a hard drive, using standard IDE or SATA connections.
4. Can SATA be used for SSD?
To install the SSD as a secondary drive (not your primary or boot drive), use a SATA cable and attach one end of the cable to the SATA connector on your motherboard. Attach the other end of the SATA cable to your Crucial SSD.
