I was wondering if anyone knew the trasfer rate for audio per track
i've been recording at 96khz/24 bit

i am about to buy a new HD and an considering
Seagate Barracuda (both)
1. EIDE 100mbs -$60
2. SATA 150 mps - $100 (includes controller as well)

just wondering if i really need the extra 50 mps i usually dont have more than 16 tracks at a time in cubase sx 2.0

and this would be my audio drive all progs are on another drive

thanks
 
If you're doing 96/24, your entire system (OS/Hard Drive/ATA Controller/Audio Interface) will have to be able to keep up with sending a 24-bit sample ~96000 times a second. for each track.
 
and it's MBps (or Mega Bytes per second...not mps or mbs)

so I guess if you do the math:
96,000*24bits= 2,304,000 bits = approx. 281.25 kBps of audio that you will be recording. Multiply this by 16 and you will need a drive capable of sending approx. 4.39MBps.




...i think that's right

Um, I think a byte is 8 bits long.... :)

:confused:
so where did i do it wrong??

96,000 bytes*24bits = 2,304,000 bits
2,304,000bits/8 = 288,000 bytes
288,000/1024 = 281.25kB

right?
 
I think he was multiplying by 16 because the original poster wanted to run 16 tracks. :p

so youre saying that 1 track = .28125Mbps ??

so a 100mBps drive can hande 355 simultanous tracks?

that seems a little high (even though ive never even see the harddrive light blip on with 20 tracks)

whats all the hubbub about sata drives then?
 
well, there's a lot more involved than just throughput when it comes to hard drives. such as writing speeds and cache. Not only that, but the hard drive has to write and also be able to monitor playback when you're writing. And when editing, you're re-writing to the drive. But hard drives aren't just for audio recording either. Throughput also comes into play when transfering files from one place to another....another important thing to think about when deciding on a hard drive. This is why SATA drives have a leg up on ATA. Not to mention they're cables are smaller/less bulkier which also provides for better air flow in the case.

technically i guess you could write 355 tracks at one time...however, you're more prone to errors and may be limited by your processor (since it'll freak out trying to direct 355 tracks to where they are supposed to go). Plus before you write to disk your computer fills up the information to be written in a buffer, and I doubt it will be able to handle holding 355 tracks worth of info.
