Overview
The JM20330 is a single chip solution for serial and parallel ATA translation. It includes the Serial ATA PHY, Link, Transport, and Parallel ATA (application layer) controller. The Serial ATA physical, link, and transport layers are compliant to Serial ATA 1.0 JM20330 supports a 1.5GHz data rate, and scalable to 3.0 GHz data rate by directly doubling the internal clock source. The application layer supports both the ATA register command set and PACKET command set, which could drive both Hard Disk Drive and ATAPI Optical Storage such as CR-ROM, CD-RW, DVD-ROM, DVD-RW, etc. The Serial ATA and the Parallel ATA application layer support both host and device operation and can be configured through a single pin.

My first time buying from here, and I have a feeling that it is going to be great. hopefully the ptm7950 does the job, I will surely be buying more stuff from here and referring people if it does.

It was not clear how to choose the color of the cables. I needed to improvise. It would be great if you offered intermediate lengths of cables too. 25 cm, 15 cm,
