Title: Cheap external SATA connector
Post by: MacTron on April 28, 2019, 09:05:16 AM
Cheap external SATA connector:
I have disassembled an USB external hard disk and plug it to this SATA external connector.

The USB is for power only and was plugged to the onboard USB on a G4 MDD and the SATA to the external SATA of a Seritek card on the same computer. Everything worked like a charm (everything under Mac Os 9 of course). The external SATA speed was amazing.
Coping a 1.8 Gb file tooks 150 seconds and doing a file search (with Norton FastFind) tooks 11 seconds
This is the results with the QuikBench app:

Later I place the same HDD onto a Firewire enclosure and the results was:
Coping a 1.8 Gb file tooks 115 seconds and doing a file search (with Norton FastFind) tooks 19 seconds
This is the results with the QuikBench app:

Just a reference I did the same test with the same Hard disk in to the original USB external box. (USB 1 speed under Mac Os 9, as a reminder)
Coping a 1.8 Gb file tooks 36 minutes and 47 seconds and doing a file search (with Norton FastFind) tooks 5 minutes.

... of course, you need a Mac Os 9 compatible SATA PCI card, but in case it don't have any external connector, one can be added using this kind of adapter:

Just to clarify to those who may have read this topic a little quickly...

This is an eSata solution, which is many times faster that the original USB external,
especially considering the USB is 1.0 under OS9.  As Mactron mentioned the USB connector only provides power and the eSata connector (a little hard to see) does all the data transfer.

i suppose you could even add something like this:

to the internal IDE port and with DieHard's adapter, get an external sata connection for your internal IDE bus.

or why not also lead the power cable out.

... but be aware that this particular item does the opposite. It is for using old PATA devices (HD's or CD/DVD's recorders) with the new SATA motherboards or PCI cards.

ah yes, you are correct. I thought I had linked the proper one.
