Yesterday I had to dig out an older G4, as another machine of mine doesn't boot anymore (seems to be the PSU, …). It is a G4 AGP with a Sonnettech 1,2 GHz. And, I completely forgot that it has an ATTO SCSI controler installed. As we are discussing SSDs a lot recently in the other threads, I wanted to know how fast these 2 attached 15k disks are, as the entire computer feels quite snappy, even for OS 9.
The 15k drives are delivering 88MB/s at read, and 55MB/s writing! That is incredible!
Only the Quantum Atlas III is damn loud, but the Seagate 15k is not annoying at all. As the ATTO controller is 64 Bit, it may make sense to think about some software raid, to increase the speed even more. Anyhow, I will stay with SCSI at this machine and not care about SSDs. The disks are working well like at the first day, even if they have not been used for years now. The machine is still rocking, and it is more than 20 years old now.
