Hi Guys,
OK, I have a 9600 I want to use for digital audio (Digital Performer 3.11). I had a Miles 2 with 2 18g 10k Cheetahs striped which are no longer working (that story will be in a different thread in a day or so). Anyway, this system worked GREAT for me and I want something similar in performance to the Cheetahs. From what I've been reading here, these ATA/SATA drives look pretty interesting (the price is right, that's for sure) but can I use these in a 9600 for audio? Thanks in advance for the advice!

While SATA works in OldWorld, and supports audio, it is 20MB/sec and affects PCI bus bandwidth. Why not just get a 36GB 10K SCSI if the Miles2 is in working order? They are cheap - if you remember when an 18GB 10K cost $300. In fact you could get one 73GB 10K drive for $235 and it would be as fast as your RAID was.

Really? New info for me TZ, thanks.
I was thinking of a Tempo controller and such for my old 9600, but your post makes sense.
And I rember all the stuttering problems from days of old.
So perhaps for dumb storage on oldworld boxes only?(still could kill bandwidth)

I had a Miles 2
Randallx, I hope you still have it.
To be honest , I embraced the Mac platform years ago for its recording capabilites.....but got sidetracked...
Someday I will plug my guitar into my computer.
Funny how life takes the wheel.
Always learning...I hope!

Today's ATA drive controllers work if you need large amount of storage and it does deliver "acceptable" performance. Until you put one of today's 10K or 15K drives to use. :D

I put a 10K Raptor 36GB in 7300 and like any Raptor, they tend to have optimized write, which was ~25MB/sec and 20MB reads.

And I don't know how 9600 would take to it, to be honest. For all I know you could use two SeriTek cards (upper/lower) and RAID across just to see or for fun, like you could with a pair of U2 cards.

I run SCSI on Beige, B&W, but on MDD those ATA drives are okay and 57MB/sec. I still prefer SCSI there, but external only, not internal. Fast disk drives make up for slow memory in older systems and you can't pry my hands off 15K drive even if it 'only' gets 45-55MB/sec, it runs OS X better.

Also, the new Atlas 10K V is a lot quieter and cooler than prior generations, while maintaining a minimum 70MB/sec, 89MB/sec outer tracks, over 1100 I/O per sec I think... I am still waiting to get one to try. The Atlas 15K II delivers 98MB/sec (Cheetah 15K.4 is ~95MB/sec) and both are optimized more for desktop use. The Cheetah, you can change firmware or something, the Atlas optimizes the number of cache segments and drive characteristics during use.

Remember there are two Miles host cards. A Miles UW? and the Miles U2W. was that just Ultra 160 vs. 320? or what was the difference between them?

I have a Miles U2W with 2 - 18 gig 10K Cheetahs (on same ribbon) in my 7500 G3/400

TZ... Kaye... any SCSI brains... ?

Miles2 is Ultra80, they didn't offer Ultra160 though it supported U160 drives. Lightning!!!!!!!

Ane Miles is UltraWide40. k

Who/where for above drive TZ? What brand, Seagate? Thanks everyone!

8600 with G3 300/512KB cache and ATTO PSC (UW 40MB/s).

Connected to a 10K6 Seagate Cheetah 36MB/s (ST336607LW).

Same drive, same Mac connected to an ATTO UL2D 42MB/s

Same drive connected to MDD/UL3D 70MB/s

G2 8600/200 32Bit 33MHz : approximately 35MB/s

G2 9500/132 32Bit 33MHz : approximately 32MB/s

G2 9500/200 32Bit 33MHz : approximately 38MB/s

So it depends on the CPU too.
