An SSD is a Solid State Drive. It is different from a Hard Drive.
A hard drive has physical platters...like an old school record player. In some cases, it has several platters. An SSD has ram chips on no moving parts. SSD is a newer, faster technology that uses less energy.
Sata is a bus interface. It is the biggest current style of interface. You also have PCI, PCIE, and a few older ones such as ATA and PATA.
So saying something is an SSD says its a solid state drive. Saying something is SATA SSD states the interface AND the drive.
TL
R Sata is different than SSD but is used with SSD's.
