G5 power mac preferred boot drive bay

[jbarley]

Always trying to squeeze that last bit of speed from my G5 power mac got me wondering.
Is there a preference in upper-lower drive bays for the boot drive?

It makes zero difference. Either one runs off the same SATA chipset. Flip a quarter and pick one that way if you can't choose.

Thank you, that clears that up.

How about heat? Is one bay or the other better for the heat produced by the hdd?

I thought about that also, so my solution was to install the boot drive (SSD) in the lower bay and the data drive (500GB Sata) in the upper.
My assumption here is there will be less heat rising from the SSD to the upper bay then the other way around.

heat really isn't an issue that I have ever heard of when it comes to the hdd

All heat generating components are an issue, hence the drive bay cooling fans.
Some early G5 power macs had hard drive overheating issues which Apple appears to have corrected in later models.

Good assumption. If I had known you had 2 drives and that one was an SSD I would have advised the same.

I used to have 2 SSD's on RAID0 on my quad. Changed my mind and removed the other SSD. I only have single SSD for my boot drive and a TB Seagate for my data and scratch drive. HDD on upper and SSD on lower, for the same reason, it is always assumed that it is much cooler at the bottom.

I just went through exactly the same process, except my data drive is 500GB, more then enough for my simple needs.
