Hi Andreas,

You can get much information concerning hard drives on the News Group
rec.video.desktop

Yes an E-IDE HDD can be used for NLE work. I am currently using two Western
Digital 4 GB E-IDE HDDs on my NLE system. One drive is used for OS/software
and the other is used for video capture and editing. My A/V drive has a
sustained data rate of 9 MB/s which will max. out my capture card (miroVIDEO
DC30) at 6.5 MB/s.

Best Regards, Cliff

I fully agree IDE is fine for NLE, but Bull shit your getting 9MB/s
*SUSTAINED*
no IDE hd has those kinds of transfer rates, the IBM 9XL 10,000rpm Is the
fastest HD on the market right now. and it has a sustained transfer of
10mb/s.. Whatever benchmarks you're using are inflating your scores
dramatically..

Robert,

Which benchmark would you recommend I test my NLE systems with ??

Cliff, the problem may be using the term 'IDE' to refer to UDMA and
busmastering EIDE drives. 9+mb/s is no problem for either of those.

Frank,

That is true, I *assumed* that everyone would understand that modern NLE
systems operate with UDMA and busmastering drivers for HDDs which are
normally referred to as Enhanced-IDE drives. Or, E-IDE as I used in my
post.

Looks as if Robert is not going to commit to a recommendation for a *true*
benchmark program.

So, I will explain the benchmark program that I use. The program was
written by a Russian programmer to be used to test sustained throughput on
NLE *systems*. Note that *systems* include more than the raw data rate of
the HDD. It also includes the interface between the HDD and the Host Bus,
Ram and Processor. The benchmark in normally used with a read/write file
size of 256 MBytes to 2 GBytes which derives an average sustained rate over
a wide area for the drive. I use the first 2 GB of my A/V drive for video
capture and the data rate is 10 MB/s at the beginning and decreases to 8
MB/s at the 2 GB point giving an avg. of 9 MB/s.

Best Regards, Cliff
