My son, the computer guru (he does this stuff for a living), tells me that in the not too distant future, hard drives will be non-existent because of their mechanical failings. They will be completely replaced by solid state storage devices that in many ways resemble USB thumb drives, but have a massive storage capacity and incredible reliability. I, personally, have experienced at least a half dozen hard drive crashes in the past decade and I know that many of the forum members have as well. I anticipate that most arranger keyboard manufacturers will eventually do away with the HDs as well.

All the best,

Gary
