How far off is IBM from offering SSD technology in their disk arrays? And what will large scale adoption of SSD do to change data protection strategies? For example, while I have heard that SSD's are much more reliable than HDD, but when they do fail, it is the whole device that is gone, whereas HDD dies slowly in most cases.
