  I must take Bob Wheeler to task over his comments about SI disks. Maybe
there is a big difference between SI USA and SI Europe but we look on
System Industries as an integrity supplier. Fujitsu make all SI disks.
 We've had 3 eagles on a 9900 for over 4 years with no disk problems (two
controller failures). We've recently put a C-Series Eagle on a HSC and it
is fine. DEC over the last year had to replace all our RA81 HDA's (the glued
v's screwed problem). An RA81 will only sustain about 22 I/O/sec and Eagle
will do over 30 (RA81 seek/latency 28/8.3ms, eagle 18.7/6.3ms)
 SI told us there was a problem on earlier C-series disks due to a
manufacturing fault by Fuji and they had to return 100's of disks, our salesman
says the problem is now fixed (and from our C-Series disk I believe him).
 I wouldn't buy another RA81 (or even RA82) while I can get better performing,
more reliable, cheaper and bigger disks from SI (the same goes for tape drives)
