Was the magnetic write head ever the main bottleneck?
Maybe not the 'main' bottleneck, but it depends on the application, no? Seems to me there are at least a few firehose situations where you can never have enough write bandwidth (say, uncompressed video-capture).
Maybe normal workloads on normal filesystems wouldn't see much improvement, but I bet you could find ways to capitalise on the extra bandwidth and space. Log-structured filesystems spring to mind for one.
