has some good details

I am going to purchase a new Dell server in
a few months to do basic file serving for 100 users.
============================================

What hard drive type do you recommend ?
  1.  solid state or
  2. regular SAS 15k 2.5"

Can I have RAID-10 on both of the above types ?

SSD drives are getting better. So long as you get commercial drives with 5 year warranties, you should be fine.

SSD drives support RAID10 as do regular hard drives.

Neither.  This is a server. Buy 2 SAS drives and mirror them.

RAID controllers are also picky about specific make models of SSDs.  Choose one arbitrarily and performance could end up being much worse than a mechanical drive.   So run the numbers on a qualified SSD to see if budget allows

The most recent servers we have purchased have hard drives in them.  However, SSD drives get ever better.

for 100 users, i would do 4 sas drives in raid 6 - though i already stated that before when you asked this question 3 weeks ago

yes, but enterprise ssd drives are more expensive and i personally can't justify the cost for a 100-user file server
save the ssd for exchange and sql databases

If you can't afford enterprise class SSDs, then don't buy SSDs.
