http://www.zalman.com/eng/product/Product_Read.asp?idx=431 We have one at work, and they work the treat for running as a cd emulator. With new firmware updates it also supports fat fs and also has Blu-Ray emulation. Definitely pimp hardware!:033:
They have been around a while, while it's kinda cool they aren't really very useful... You can make any os installation ISO work from a bootable USB hdd anyway, same with application installation files. It just emulates a USB DVD drive, I don't see how that would be helpful to game dev at all... If it was, you could just plugin a USB DVD drive and have the same thing. edit: Thinking about it, I guess they would be good for a small shop that do lots of different OS installs so they dont need to recreate bootable USB drives (if the boot method varies). For Windows its not needed - you can launch the setup from WinPE. Any larger shop would be deploying via network (this is currently what I do - I work in deployment).
Except for the ISO loading software pre-installed it looks just like any external enclosure for 2.5 hdd's. Does also have a little LCD screen which i don't remember seeing on other enclosures.
A friend of mine who was both an electronics and software engineer started to make one of these back in 2003. I don't know if he ever finished it, but loading an ISO off a removeable HDD as a fake CD drive was very desireable back then. Very useful device though due to the above reasons already stated by others, not as useful today. If it did USB 3 it may be tempting to pick one up and drop an SSD in though.
I must be missing something here, like stated above, can't you use any HDD to load an iso? Or what about making a virtual cd drive and loading off of that?
Normally you have to boot into an OS for optical emulation - this lets you emulate in BIOS so you can install the OS (or anything else for that matter) with no other tools required and at a significantly faster speed. Maybe it cvould be made to work for booting games on consoles too, which I guess is the point of the OP.
So its more than I initially thought, Can't you just use something like unetbootin to mount an iso on to a USB flash drive?
