They're still in business?
Maybe they have managed to sort their hardware/firmware issues over the years and managed to produce stuff that actually works. They had some serious issues if a disk died (or the controller/array just imagined it had died). The only redundancy they had was being made redundant and kicked out the door to be replaced with something that worked. Real shame really, since on paper the kit looked good.
Glad to hear they have managed to sort their stuff out and still stay in business.
