Two Indys, one R5000 based system and an older R4400 based system
Sony power supply.
MAC Address: 08:00:69:09:AB:E2
The storage is based on SCSI2SD. This allows the usage of SD-Cards instead of 50-pin SCSI disks. It's slower than actually using a spinning disk because SCSI2SD is not a high performance solution. The SCSI2SD site states about 2.6 MB/s as the best achievable speed. The advantages lie within the lower heat and noise emissions.
Note: SCSI2SD (firmware v4.6) does not support SCSI SYNC. From time to time error messages complain about SYNC failures which can be ignored.
If you are curious, here is a diskperf run on this Indy with SCSI2SD:

It looks like the better CPU of the R5000 based Indy leads to slighty better performance with small files. However it's still in a very low performance segment on both systems. But then, these systems are oldies by every standard. I have no explanation why the last two backward (bwd) read and write tests resulted in 0.00 MB/s.
