A1: SATA stands for Serial ATA, in contrast to old Parallel ATA (IDE, EIDE,
ATA and ATAPI) technology. SATA starts with 1.5Gb/s specification, and
evolves to 3.0Gb/s specification, which is commonly referred to as SATA II.
Hence, original SATA 1.5Gb/s is called SATA I to distinguish with SATA II
3.0Gb/s.

Initially SATA was designed as an internal or inside-the-box interface tech-
nology for storage device like HDD. Both SATA I and SATA II hard drives
use plug and receptacle interface with “L” shaped key as shown below. 

This connectors and cable(flat) with “L” shaped key support both SATA
1.5Gb/s and 3.0Gb/s, however the cable length is limited to 1m(around 3.3
feet) maximum. When this manual was written, majority of SATA ports pro-
vided by computers or add-on SATA host adapters are the receptacle with
“L” shaped key. Our PHR-100SU includes an 80cm cable with SATA connec-
tor with “L” shaped key to support majority SATA port in the system.
