- I am thinking of getting an R4K indigo for home. The main use
- would be fortran and C programming, and visulaisation work. I am hoping to
- get information on the following points:
-
- 1 ) Regarding the disk:
- the 432 would suffice for disk space needs as I will also have a
- dat drive for offline storage.
- I am willing to pay extra for the 1 GB drive if it has superior
- performance both in random access mode and in raw transfer
- a ) does anyone have any performance numbers on an R4K indigo with
- both options as the system disk and compare them?
- b ) can these numbers be seen qualitatively?? ie - do compiles and
- large disk accesses appear perceptibly faster ?? Can you
- see the speedup in graphics if paging/swapping is occurring using
- the 1.2 GByte disk over the 432 MByte disk ?
-
- 2 ) Regarding the monitor:
- I can only afford entry graphics for starts. Hopefully in a year or
- so I can find the money for ELAN. In the meantime ,
- a ) there has been a controversy over the quality of the starter
- graphics monitors and whether the 16" sony was better than
- the 16" Mitsubishi. Can someone who has used both comment on
- how they differ and whether it is worth specifying one or the
- other on the order.
- b ) I am told that in terms of features:
-
- the Mitsubishi can scan at 60Hz,72Hz and 120 Hz
- (at 1/2 vertical resolution) whereas the Sony cannot
-
- are there any other feature differences?
-
- In particular, I understand that both the Mitsubishi and the
- Sony can go to 1280 x 1024 resolution. This is an absolute
- requirement for the monitor.
-
- 3) What modem works well with slip?? I need the highest speed possible
- that works over a phone line as I won't be able to afford a leased line.
- What speed works reliably oveer the phone line?
-
- 4) Does the UPS sold through SGI express do the job in terms of power
- protection as well as battery backup? Any good/bad experiences with it
- in lightning and brownout conditions ??
-
- In particular, is the Smart UPS400 good enough for the power
- requirements of an R4K Indigo ?? Or is it marginal ??
-
- Many thanks for your help.
