- You need to keep the disk cool enough.. a case and a fan.

- We have used this.. but then we bought a digital thermometer
- and measured disk case temperatures at various cases.
-
- A Seagate Elite 2 reached 77 degrees centigrade in a normal desktop PC
- case with a fan only in the power supply.
-
- In a PC tower case with 3 fans and two Elite 2 disks
- - lower of the disks was cooled but
- - the upper one went again over 70 degrees,
- and there was no easy way to force any airflow around it.
-
- We had also a HP disk case, which takes 7 half height or 3
- full height disks. The temperature with 3 full height disks
- was about 40 degrees centigrade at every disk.
-
- The case comes with *three* SCSI cables: a telco-telco, a sunHD50-telco,
- and maybe a sunHD50-D50, i can't remember.
-
- The catch is that HP disks have a special 'tray' under them, and
- the case is made for them.. the mounting hardware is not included
- in the case.
-
- The case was not very expensive, if you can use the sun cables.
