If I have a system with about 60 thousand tags, about how much space should I have for archive space on my server?

In the latest PHD software change notice, Honeywell states the minimum amount of disk space for different size systems:
Collector

  • Small (up to 10,000 tags): > 100 Gigabytes
  • Medium (10,000 – 25,000 tags): > 250 Gigabytes
  • Large (25,000 – 50,000 tags): > 500 Gigabytes
  • Very Large (> 50,000 tags): Contact Honeywell

Shadow

  • Small (up to 10,000 tags): > 400 Gigabytes
  • Medium (10,000 – 25,000 tags): > 1,000 Gigabytes
  • Large (25,000 – 50,000 tags): > 2,000 Gigabytes
  • Very Large (> 50,000 tags): Contact Honeywell

Keep in mind that these are the minimum requirements and you are requesting what Honeywell would consider a Very Large system. I would say that it all depends on the scan frequency that you will set for those 60,000 tags and your requirement of years of history which is generally 3-5 years. 
With all this being said, 2TB of disk space will be enough for your 60,000 tags taken in one minute intervals for five years.
