server disk upgrade question

[Jim Patterson]

I have a dilemma that I am hoping to get help from the group with.

I need to add more disk to one of the servers here.  I have 2 candidate
systems, a 4D/210 with 32 Mb and an ESDI controller and a 4D/35 with 16
Mb and an SCSI controller. 

Each system already has one disk, I will to add one or two more disks
for use with NFS.

Does anyone have an opinion about which machine would be a better disk
server?  Both machines are already moderately loaded doing computations,
we can't afford a dedicated file server.

Send me mail or post, I will summarize everything I get to the list.

Thanks
