SATA (Serial ATA) is a serial bus typically used to connect a PC to mass storage devices. It was developed as a replacement for the ATA parallel bus and offers many advantage including hot-swapping, increased transfer speed and reduced cabling cost and size because fewer conductors are required.

Why does the SATA power connector have so many pins?
With only 4 cables, two of which are ground, it seems like it has way too many pins. Why is this so?

Is USB-C a technically viable substitute for SATA Express connectors?
SATA Express, the successor to SATA, is too new to be widely used yet, but the advancing speed of SSDs appears to make it inevitable, the same as SATA replaced parallel IDE. Despite the name, it isn't SATA at all; it's either the AHCI or the NVMe…

Why SATA is simplex even though it has separate TX and RX pairs?
Why is SATA simplex even though it has separate TX+/- and RX+/- pairs? Why can't it be full-duplex like SAS (which has the same interface with multiple ports and is full-duplex).
If I am wrong with this concept please correct me.

Hard drive that has the ability to "read" old data while it performs a write?
Is there a hard drive (protocol command, specific model, etc.) that, while writing new data over old data, it "read"/return the old data back to the controller/OS? (Analogous to a simultaneous read-write).
I've been looking up SATA/hard drisk…

Simulate HDD using ATMega168
I'm going to start a new project and I wonder if the concept makes sense.
(I'm not so familiar with ATA specifications to answer this by myself :))
The concept:
HW design:
"SATA connector on motherboard" <-> "SATA cable" <-> "SATA/IDE HW converter"…

Is there a way to split a single SATA port into two SATA ports?
I am making a very low-cost system with a Allwinner A20 chip as the heart. I would like to have a main boot drive and a separate disk drive. Sadly, to my knowledge there is only one SATA port.
I can't drop either for various reasons, and this is an…
