# What are the determinants of SSD speed?

The overall performance of SSDS is determined by the hard disk interface (**SATA, IDE, PCI-E, etc.**), the **Controller IC** (scheme), the efficiency of the **loss-balancing algorithm** (firmware), **the raw flash bandwidth**, and the **circuit design and manufacturing process** of the PCB version.
