esata vs. huge u320 setup
I have been having some mysterious data loss on my power pc
G5, 2,5Ghz with 2 G of Ram; so I was wondering if esata would
be a newer and more reliable than the present set-up of
UL4D and the two 1.2TB Huge U320 drives.Thanks

When was the last time you erased the unit?
When was the last time you ran Disc Warrior on it?
How large is the array? how much media do you have on it?
Older drive arrays do not suddenly “lose media” that I’ve ever seen unless they have not been well maintained. Fragmentation on an array is a data killer. We try to erase our arrays at least every three months to keep them running clean.

The data loss occurred on May 14th, 2008.
When I was in finder a 50G directory became a 50M directory in front of my eyes.
The drive then didn’t mount, then I repaired permissions this didn’t work so then I
ran disc warrior on it the same day. Naturally all the data (we needed was gone).From talking to our vendor and Ciprico it is a mystery problem.
The array is 1.2 TB Huge System.
Since is was a mystery data loss (the drives were erased last July 2007)
our vendor suggested we switch to a new esata drive “solution”What I was asking if if esata can keep up with uncompressed HD in a RAID.
I have heard SCSI is on the way out!
Thanks

If you have enough drives striped together, yes. We’re running SATA with SAS connectors topping out at 500MB/s in RAID 5.

SCSI has been on the way out for over 4 years now.

I guess we are beat anyhow as our Power PC Dually is not esata
compliant anyhow; and they do not sell dual channel esat controllers
for the power PC. -

So you have a Sata solution up and running on a Power PC.
This is encouraging; my vendor told me there was no way unless
we upgraded to a Mac Pro.Is is fairly stable; and what is the throughput like.

Yeah, two PowerPC’s actually. The Quad is a G5 as well.
The LaCie units we’re using only run about 150MB/s but we don’t do uncompressed HD on there. We could get a faster array or stripe two together if we wanted to, but I only put DVCPro HD projects in that room.
