Personally I like Suns since they work first time and are very fast. Dual 170Mhz Sun Ultraspar with 14x2Gb RAID array + DLT 4000 tape drive. 20Gb tapes eah (40Gb compressed) + ontape archives 56Mb in 14 seconds i.e. 14.4Gb/hr! Amazingly fast for 4GL compilations (1000 files + 100 library modules) in 1hr (only using one CPU as a single makefile!). Reminds me, must put GNU make on their and do parallel makes!! Also one a single CPU machine (Sun 170Mhz Ultrasparc) running Online 5.x we loaded 500Mb of data in 1/2 hour (including index creation) and archived it in ~15 minutes... Crispy! -- David Williams
