purchasing new workstation want to know advantages and disadvantages of a RAID 5 hard drive array. Is there a better RAID array than RAID 5?
Set up would be SSD boot drive with 3 x 2 TB parity drives.
workstation is HP Z820 with Xeon E5-2697 12C processor.

There's no universal answer to this question.
We need to know some more details
What kind of drives are you using?
For what purpose are you using this storage array?
What kind of data will be stored there?
What kind of uptime/downtime are you willing to tolerate?
What does your backup scheme look like?

unwilling to tolerate downtime. type of data will be sensitive personal along with photos.

If you have that, you probably don't need a RAID system.

in terms of the rebuild times for a 6TB array in RAID5 it can take a long time. You may be running in degraded mode for 5-40 hours assuming you have a spare drive ready immediately, so there is some chance of another problem occurring during that time. Overall the downtime is going to be pretty low and Data loss very, very unlikely with a RADI 5 and proper dedicated backups.
