Whilst I'm pretty au fait with the workings of my G5, (my previous Sawtooth & G3Beige before that were heavily modded & rebuilt), my main concern was whether in "real world" computing, the difference in performance between 7200rpm and 5400rpm SATA2 drives would be sufficient to justify the additional cost, when they would be on a SATA1 controller. Your (very rational) assistance helped me weigh up pros & cons effectively. Since my major desire is simply capacity, I'll go for the 5400rpm drives, and add the difference to my piggy-bank, saving for an Intel Mac tower, subject to approval from a) Bank Manager and b) more importantly, She-Who-Must-Be-Obeyed.

In real use there is no difference in SATA 1.0 and SATA 2.0 for single HDs. There is also no difference in speed for RAID 0 (stripped) pairs of two HDs. The only place you might be able to see a real world difference would be a RAID 5 array of HDs. It also might be faster to use Solid-State Drives (SSDs) instead of mechanical HDs, but these are still very expensive. I know this from experience. I mistakenly thought that the SATA bus speed was a limitation, but it's really the latency of the HDs that is the limiting factor, and latency hasn't changed much at all. Also, some SATA1 controllers are essentially SATA2 with the exception of support for rarely used feature called SSC (Spread Spectrum Clocking), so an SATA1 & SATA2 controller could be pretty much identical. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: New Disks in G5
I would go with the 7200RPM, going from a 5400 to a 7200 even with an IDE drive is a big difference.

New Disks in G5
Hi All, I have an early 2005 G5 dual 2.0, maxed out at 4GB RAM. I want to put some huge drives in it, and am looking at Samsung F3 1TB 7200rpm drives. There are places (in the UK) where I can get the Samsung F2 1.5TB drive for not a lot more, although it's only a 5400rpm drive. I'd be grateful if someone with greater techie knowledge than me could advise me on whether the fact that my G5 is SATA1 so 150Mbs as opposed to300Mbs SATA2 is going to mean the 1.5TB will not be noticeably slower in use. I currently have two Seagate ST3320620AS 320GB 7200rpm drives in there, and they are perfectly fast enough for my use, although they're getting a little full now.
