The Return of SCSI

Show all headers | View raw

There was a time when high-performance disk drives used SCSI - the 
Small Computer System Interface - and everything else was kid stuff. 
Now, advanced forms of SCSI are still around but there are other 
high-performing disk interfaces, too. But some old gear really loves 
their classic SCSI ports, and [Adrian] decided to try hooking some of 
them up to some modern computers. You can see how he did in the video 
below.

The key to the attempt is a USB to SCSI adapter which was unusual but 
not unheard of, and [Adrian] came across one from 1999. Of course, you 
have to wonder if a modern computer will support the device or will be 
able to load the drivers from the old CD.

One of the problems with these adapters is that SCSI was a 
high-performance bus for its day, and the corresponding USB speed was 
not so much. Parallel SCSI used differential signaling and could reach 
up to 320 MB/s. Ordinary USB weighs in at 1.5 MB/s. USB 2 did a little 
better, but it would take USB 3 to eclipse the old SCSI data rate. Of 
course, SCSI went serial like USB and modern serial-attached SCSI can 
blow the doors off even the fastest USB devices.

We doubt you really need to use a SCSI device as an everyday thing, but 
you might want to or need to read one that shows up. Plus it is just a 
really interesting look into the way things were. Finding the drivers 
were, as you';d expect, a real pain. Turns out, he probably didn';t 
need to bother as Windows knows how to treat it as a storage device but 
he didn';t figure that out right away.

Android didn';t seem to work as well, although that may have been 
because the phone didn';t recognize the disk format.
