hi Spoimala,
unfortunately several companies use those " - marks to promote exactly the opposite of what you intended
They call it Hardware Gigasampler, but it's of course just a PeCe.
Gigasamples can only be played under some flavour of Windows OS

due to the 'coding' of attack signals in memory, decay streaming from disk. That's programmed very close to the OS. Since Tascam bought the technology they might offer a unit someday, but I wouldn't hold my breath on that.
If you'd convert large Gigas to even more large Akais, you wouldn't gain any reliability. I'm pretty shure you can reboot a current machine with Giga 3 times before you've loaded such complex (if you get them converted) programs in a hardware sampler.
I consider Giga reliable in a simple stand alone setup (as already mentioned) and you may of course use whatever sound hardware that fits your needs, but I don't see a different way of using those samples.
cheers, Tom
