FastATA 4000 MK-V released

[Darrin]

Good point.  :-)

I was fogetting the wedge machines (although there are Zorro adapters available for some) as this thread was originally about a Zorro card.

[kreciu]

I have Zorro II in the paper box, wrapped in foil and waiting. I will sell it next 10 years for $1000. Just a joke

I use two A1200. There is NO USB "solution" for this computers. I always wander what I did that I can't register Poseidon for Spider? I past some people could do this. It's a punishment for not supporting "Amiga world" for some time? :-D

For someone who has a desktop A1200, Subway USB is OK (speed like 0.5 Mb/s is great...), but for Towered Amiga's? NOTHING.

I'm done since it's offtop  :roll:

@ Kreciu

Is that because your clockport in your tower is covered up?  I have 2 A1200 towers and one of them has the Power Flyer Gold IDE adapter in it which blocks off the clock port (and was a {bleep} for fitting an internal scan doubler).

[kreciu]

Clock port is waiting for Delfina . Can I use both a the time? Thank you for asking. BTW. Look at my case

I can't make it out.  Do you have a link to a bigger pic?

I forgot this think works on ZorroIII . I can't tell from "experience", maybe someone?

Here. You can make about 15.3MB/s on Zorro III if you are nasty and occupy the bus with 100% load, leaving no bandwidth for any other device sitting there (like a gfx card), and eating up 100% CPU time (which is not what multitasking likes).
I assumed a single cycle time of 250ns (including the small delay between cycles).

You can measure it yourself with "bustest" (which is amazingly accurate when comparing to a scope or logic analyzer).

Some values from my setups here:

A4000D, CS MKII 060@50MHz:

DENEB: 7.5MB/s read, 11.8MB/s write
CV64:  5.4MB/s read,  6.7MB/s write

BTW. Personally I'm waiting for something truly, really etc. new.

It is. At least the EPROM and the MACH chips on it are "new", the rest of the board looks like the 1999 version of Fast ATA 4000, compare yourself in amiga.resource.cx) :-)

ofcourse it is the same design, the way I see it they just upgrade the "software" inside the chips...
same as the new mediator mach chips that came with the MMCD driver upgrade...

Its like USB2.0 which can make up to 480 Mbit/s but in real life you will get only about 320 Mbit/s or less even on modern PCs which makes it slower than FireWire 400.

IDE on amiga is a mess, it eats all your cpu. Only the Deneb has DMA which makes it useable with IDE devices without freezing the whole system during file operation. If Deneb is too expensive for someone I would rather go for a Z-III SCSI controller.

[Darrin]

@ DJBase  

However, in reality, your typical user will be more than happy with most fast IDE devices available.  I've used Buddha in the A2000 and A3000, Power Flyer Gold in the A1200 and the FastATA4000 in the A4000 and even though I also have SCSI in the A1200, A2000 and A3000 the IDE options are better for me because I have plenty of cheap, large and fast IDE devices littering my office without having to scavenge some dusty 4x SCSI CD ROM drive off eBay.

I think the user can live with a little extra load on the CPU for the time it takes to load a 256KB file or load Deluxe Paint.

No, sorry. Both are serial busses, and both "suffer" from the same bandwidth eaters: 8b/10b coding, bit stuffing, sync frames, protocol overheads.

So if you compare both serial busses you need to give both a reduction of 33%, to be fair :-)

I had no problems with fitting my fast serial port into the clockport with a Power Flyer Gold, but the scandoubler did need a trim.

Sadly the new Indivision scandoubler wont fit with Fast ATA + Mediator and now the IDE Express looks to be sold out.

Sure, FW400 doesn't reach 400 MBit/s but its faster than USB2.0 in real life. Thats what I wanted to say.

[SHADES]

I just use my fastlane SCSI card which is DMA enabled and I have no issues with CPU usage.

A friend of mine missed the response time and now it seems unavailable in elbox webshop.
Anyone knows how to get the update now?
