I am interested to find out who has gotten some great transfer rates with their existing Amiga setups. I would like to hear from people who have tried 10000rpm / 15000rpm SCSI hard drives on their Amiga.
I'll start off by saying my IBM 9Gig Ultra SCSI HD transfers at 13Mb/Sec on my Cyberstorm MKIII. I have ordered a 147Gig 10000rpm U320 HD (due to arrive this week) so I am hoping to start breaking the 30mb/sec mark.
Anyone else care to add their experience?

Sounds like you are just bragging to me. Why do you need these transfer rates and what do you actually do with it? Is it just an ego trip? My Seagate SCSI harddrive transfers at 30 Mb/sec, try to top that! My Atari ST transfered data at 10 Mb/sec back in 1988. BIG DEAL, SO WHAT, WHO CARES !!!! :-D
-
I have some 18 and 36 GB 10k and 15k disks and their speed hover around 30 MB mark; some other users have reported a little over 30 MB. As the theoretical max of the interface is 40 MB, there isn't much point to try to squeeze the last speed drops by overspeccing the disks.
-
He! He! The faster the better! :-)

I have about 3.8MB/s with my A4091 and a Quantum
2 Gig (SCSI II) HDD...
Probably I can go faster with a modern SCSI-Drive
But I won't because I have a silent miggy now
10000 rpm HDD are noisy and I only use them for servers...(Who cares about the noise in the server room)
@DoomMaster can you stay away from here ?
I'm getting sick from your annoying posts/replys
Thanks

I've got 9.7MB/sec with BlizzardPPC SCSI2, by using IDE HDD (various) and Acard AEC-7720U SCSIDE (http://www.acard.com/eng/product/scside/aec-7720u.html). This is very close to theoretical maximum.
My Pegasos gives peak performance of 37MB/sec by using Seagate Barracuda 7200.7 (ST3120026A (http://www.seagate.com/support/disc/manuals/ata/cuda7200pm.pdf)) 120Gig HDD.

About 30MB/s on my Pegasos with Seagate Barracuda ST380021A (80GB,
7200rpm). Ultra ATA is awesome, arent it?

Oops, not an Amiga setup in strict sense but mentioning A1200 IDE
benchmarks is not worth of laugh.

That's is the first I've heard of this - very interesting. Not only does it allow fast transfer speeds, but also use of cheaper HDDs. Cool

On my A1200 060 with fast scsi II with asyncron mode the maxium speed on my system is 10,3mb/s and my ide with ide fix splitter+buffer 3,8mb/s
-
A1200, B1260: ~2MB/s from both internal IDE and X-Surf IDE (both 3-gig 3.5" IDE disks).
-
A distant memory but I think my quantum bigfoot was getting around 7Mb/sec on my powerflyer. The interface manual said it could do up to 16mb/sec, but I'm guessing thats with an 060 and a nippy hard disk :)

WHAT ?! :-o

Hi, DaNi!
I have also an A1200/060/SCSI (but only 50MHz, not 80 :¬) and I was wondering why are you using asynchronous mode, while synchronous mode would give you better speed. At least, with my old 2GB Quantum Fireball I get nearly double the speed with synchronous mode than without it. Could you please explain it?
Saluditos,
Ferrán

48MB/s on my Pegasos.

3.8 Mb/s with IDE - splitter/Fix and '060...
I was actually hoping for more from this
device but it's better than stock at least.
My Pegasos gives peak performance of 37MB/sec by using Seagate Barracuda 7200.7 (ST3120026A) 120Gig HDD.
About 30MB/s on my Pegasos with Seagate Barracuda ST380021A (80GB,
7200rpm). Ultra ATA is awesome, arent it?
I just bought an 80Gig Barracuda to use in my
Pegasos 2. From what I researched, it seems like
a well - made and quiet device for the money.

hmmm, i got 18mb/s out of my old quantum atlas2 10k rpm 9Gb drive.
abaout a couple of years ago, i was in a meeting with some raid / drive technicians and they were saying how the firmware for 9Gb drives had pretty much stopped development as hardly anyone was buying them anymore just tweeks to handle 10k 15k rpm spin speeds. if you wanted a drive to deliver a decent data rate, then you had to buy 18Gb or bigger as that was the way the market was going, so then these drives would have updated firmware to properly support the newer scsi interfaces.
so given that the Symbios 770 chip on the cyberstorm was pretty good for the time, to get better rates, get bigger drives. (more cache ram etc.)

@ DoomMaster.
Well this should have gone into a thread of its own but what the hell. Basically i think i speak for a BIG % or users here, when i say YOUR GETTING ON MY NERVES. Please! Try to help people here and they will try to help you. Whether you have Millitary Spec Amigas or not, we dont care. Is it a professional Computer? Dont really care about that either. What i do NOT appriciate is you calling my hardware a toy. Plese refrain from doing this. Basically Doomy, what i am asking is this. If you want help here, ask for it. But dont then tell people they dont know what they are talking about - if your really THAT good, then you dont need help from children like us with our toys so you may then leave us alone. If your prepared to accept the fact that everyone is entitled to an opinion, welcome to amiga.org :-)
This is getting old now... but i thought this needed to be said. The amiga community is small, and in order for it to grow it needs to be kept together, not divided even further.
Thanks

Yeah, DoomMaster, you get on his nerves!
there, said it!
-
LoL :-)

Hi LinchpiN
i agree with you at 100% . . .but now i'm still to understand what DoomMaster is.
He is not real, he is a sort of entity or worse, a bug in the XOOPS system. :-D
Ciao!
-
Hahaha!
-
What i'd like to see from Doomy is a 1/2" plate A2000 with sound proofing. Motorised tracks on the bottom and a built in smoke generator.
Now that would be a professional military computer.

All my Amigas are toys. I am going to pick up my toys and go home! :-D
