Several PPC cards on Amibench

@Jose,

What happens if you have got a Power Flyer, like me? Hopefully, i will send the money out today or tomorrow, if i get the all clear from him. I am sending him 2 payments.

I agree with Jose, GET ONE WITH SCSI. I bought the cheapest version available back in 98. The 040 is bearable but the lack of DMA SCSI is not .

well, you just get higher transferrates at nearly the same high CPU-load the onboard IDE generates.
All IDE controller for the Amiga generate between 80-99% CPU load while accessing the attached drives, so SCSI is a must for a seriously used Amiga.

Any idea roughly on the CPU useage for say the UW-SCSI on the Cyberstorm?

[Lemmink]

I didn`t manage to push the CPU load above 20% when checking the UWSCSI on my CSPPC/060 with SCSI-bench. I tried every cobination of settings for the test from best to worst. I got values from 14% to 18% while being total idle the systemload was at 7% to start with.

[NightShade737]

Ooh, thats nice to know. So not only is it Xx50 times faster, it also uses alot less load.

Back to the original subject, has anyone who bought one recieved it yet?  I expect to get it today or tomorrow but I'm still waiting.

Mine went out a few days ago, but since I'm from Canada and the package is arriving from Germany, it could be around 2-3 weeks of waiting before I see it. Sometimes earlier (1 week), but on a rare occasion.

[Jose]

I've only bought mine this Monday afternoon so it should still take some time...

[CU_AMiGA]

Right, i am sending the money today. He had better send me the card when he gets the money, or he'd better watch out!

Surely a Power Flyer ain't THAT much slower than a SCSI?

[NightShade737]

The flyer would achieve a maximum of 16.6MBps in PIO mode 4 (or 5 depending on how you look at it) and would use 80-99% CPU time. The UW-SCSI on these accellerators is 40MBps max and as said before, uses about 20% CPU time maximum. So yes, it is quite a bit slower and less useful generally.

onestly, i've never seen a PowerFlyer, to go more than 7-8 MBsec (with a 060) and no more than 5 MBsec with a 040 (with quite 100% of CPU usage).

So, IMHO DMA UW-SCSI is the optimal solution even with those SCSI2IDE adapter. (~8 MBsec with a modern  and cheap IDE disk).

[NightShade737]

Yeah, thats pretty much why I said Max.
Currently my drive scores about 1.5MBps, so when my CSPPC arrives and my new UWSCSI drive I think I may be somewhat pleased

[CU_AMiGA]

Anyway chums,

Morely back on topic. What would happen if this "geezer" was ripping us off. What can we do about it? I am giving him two payments (already sent first one) and he says he is sending the card after first payment. Payment was £115.

[NightShade737]

Well I paid by Credit Card, so the CC company would chase after him on my behalf...

[Framiga]

Hi CU_AMiGA,

have you got a real name/address from those guy?

He lives in Germany? and, sorry but i don't remember if you too?

I think should be only a shipment delay. It is too early, to think to a ripping IMHO.

Good luck :-)

Ciao
