It caches both reads and writes, but can be configured as just a read
cache. I ran NetBSD 0.9 for months with out any problems with the card
(the disk performance was great!) but after the upgrade to -current I
stated getting those wd1: lost interrupt and wdc0: busy too long
errors. I never had any problems with 0.9 (except a few wd1: stray
interrupt errors during boot).
