View Full Version : ULTRA ATA133 Card

Mar 7, 2005, 09:14 PM
What type of performance should I be expecting out of my Sonnet Tempo ATA133 card? The main reason for getting this card in my digital audio G4 was for big drive support but I was also looking for a pretty good performance increase. Here are my xBench scores.

Disk Test 115.82
Sequential 108.41
Uncached Write 84.58 35.26 MB/sec [4K blocks]
Uncached Write 85.50 35.01 MB/sec [256K blocks]
Uncached Read 160.03 25.33 MB/sec [4K blocks]
Uncached Read 140.28 56.68 MB/sec [256K blocks]
Random 124.32
Uncached Write 141.95 2.13 MB/sec [4K blocks]
Uncached Write 144.13 32.51 MB/sec [256K blocks]
Uncached Read 101.50 0.67 MB/sec [4K blocks]
Uncached Read 119.90 24.68 MB/sec [256K blocks]

Are these normal or is there something else i should be doing? The drives also do not show up in Apple System Profile and I am not sure if this affects anything.

What exactly is XBench testing there? Which disks? Which bus?

I wouldn't put much stock in the results.

Both of the Western Digital and Maxtor drives produce the same results...they are both 7200 rpm 4 mb cache drives...the Maxtor is on bus 3 and the WD is on bus 4
