"They're also not very fast, especially when writing.  We're getting close, but we're not
there yet."

Yes, we are getting close. From what I read, we can look forward to 100MB/s writes in the very
near future. Furthermore, they scale really well:

"Yes, we are getting close. From what I read, we can look forward to 100MB/s writes in the
very near future."

But is that for continuous writes or random writes?
The latter case matters more.  I replaced the hard disk in my notebook with a compact flash,
which can do 20MB/s continuous writes (which - while not exactly fast - would be more than
enough performance), but slows to a crawl (in the KB/s range) on random writes, especially
when cache flushes are involved (FS metadata updates, fsync&co take ages).
