RE: 2TB SATAs on Seritek for my Quicksilver Dual 1GHz

2010-06-16 Thread Stewie de Young 



 From: billycarm...@verizon.net

 Currently have good success with a 1TB Seagate SATA and a Firmtek  
 Seritek 1S2 SATA Controller on my Digital Audio Dual 533 OS X 10.5.8.
 
 Anyone have experience with the so-called energy efficient LP Seagate?
 http://eshop.macsales.com/item/Seagate/ST32000542AS/
 
 Its 2TBs but shows as a 5900rpm drive. My other SATAs are 7200rpm.
 
 Since the SATA drives are so fast, would I notice the drop in  
 rotational speed using for video capture work on my Quicksilver 2002  
 Dual 1GHz under OS X 10.5.8? I feel yes, but wonder if anyone has used  
 it.
 
 Trying to justify putting another $200 (SATA controller + 2TB HD) or  
 so in my QS ...
 
 Thanks

Probably not as it has a 32mb cache despite the difference in RPMs.
At a rough guess I'd say a SATA 7200RPM drive with a 16mb cache would perform 
much the same as this drive with the 32mb cache ( depending on what you have in 
there already )
I'd look at drive benchmark tests at one of the PC sites but the best results 
as we know are in real world applications.
http://www.barefeats.com/ usually has some good drive comparisons but this may 
be too new for them to have performed any benchmarks yet.

Thanks ... how could I forget barefeats:

My Seagate ST31000528AS 1TB 7200 interrnal to my DA Dual 533, shows a  
Quickbench of Read 90MB/s and Write 89MB/s for 100MB Extended Tests.


Looks like the Seagate LP ST32000542AS 5900 clocks in at Read 116MB/s  
and Write 110MB/s for 1GB Extended Tests (special version of  
Quickbench I think) on a Mac Pro. Hopefully I'm taking the similar  
numbers off their findings correctly, maybe not ...


Different environments for testing for sure.

Will continue to investigate ...
