SSD And The HDD Interface Limitations
Originally written by
- The HDD interfaces were designed with slow devices (rotating disks) in
- As such, they introduce a very large latency on top of that of the FLASH
memory of SSDs.
- If an SLC FLASH memory can support a latency of ~25 micro-seconds to
fetch a 4KB page.
- The SAS or SATA protocols may add more then a 100 micro-seconds
- In addition, going via the system peripheral bus can limit throughput.
