Backup -- to disk instead of tape ?

What "backup to disk" APPLIANCE
vendors offer something like below
"Desired Steps" since I am trying
to get away from TAPE so I can easily
GROW into BIGGER hard drives if/when needed ?

Also, I assume you can reuse
backup TAPES more times then
you can reuse backup HARD DRIVES ?
----------------------------------------
Current Steps
 1. Norton Backup Exec software
    Saturday NIGHT full backup (10TB) and
    Weekday NIGHTLY differential backup (~1TB)
    run on main Windows 2012 R2 server, backing up
    three PHYSICAL servers, each with 2 HyperV VMs
 2. every morning
      ** eject tapes
      ** insert new tapes
 3. every night
      ** take tapes offsite
