Re: Can't add USB?
These only make sense if the system can't take a USB card. The don't make sense if the system can take a USB card.
It could make sense in both cases, particularly for systems that don't natively support either USB or boot from USB. But then it would make sense for the Ethernet port to be replaced by a USB port. [The built in USB port seems to be for firmware flash and real-time diagnostics only.]
Only problem I can see is the speed of the IDE interface.
Looking through www.ssd.gb.com and www.reactivedata.com websites, it would seem that SSD Ltd have found a lucrative niche market; it is easy to forget with all the hype that the Windows PC architecture isn't the only computer system platform in widespread usage.
