FastATA 1200 MK-IV Available For Pre-Ordering

[SHADES]

In my experience with Classics, Deneb, and DMA vs. PIO, you really don't gain much by using the Deneb in DMA mode.  When you are driving these devices so fast on the Classic systems your CPU is still being used quite a bit and DMA vs. PIO is about a 5% difference in CPU usage.

It's a general lack of CPU horse power and other sub-system slowness (like Zorro III) that are more of an issue.  My recent networking tests using a Deneb in DMA mode (OS 3.9) and PIO mode in AmigaOS 4.1 Classic showed only about a 5% drop in CPU usage in DMA mode.

Huge difference for me on SCSI Vs IDE. 60% almost. oh, and the SCSI is faster copy to and from RAM. consderably.

I did a quick test using the updated diskspeed program from Joerg Strohmayer:

AmigaOS 4.1 Classic, Deneb PIO Mode: 3.55 MB/sec, 96% cpu usage

AmigaOS 3.9 BB4, Deneb DMA Mode: 3.866 MB/sec, 41% cpu usage

So you are correct with hard disk transfers - DMA does make a larger difference.

Same disk in the same machine with the same partitions under AmigaOS 4.1 Classic and AmigaOS 3.9, using FFS2 (DOS\07).

I was 28% CPU but meh, not a big deal oh and around 6MB a sec but been a while since i re-tested. That was a Z3 Fastlane with Segate 540 MB SCSI2

Is this version of Fast-ATA for A1200 compatible with Lyra KB adapter?

[HammerD]

thanks for the test!

Could you please test AmigaOS3.9 BB4 with Deneb in PIO mode just for completeness? :-)

PS: I think you should get higher speed with a CSPPC:

I use scsibench for testing HDs http://aminet.net/package/util/moni/SCSIBench

I've got some new test results up using scsispeed.

http://www.hd-zone.com/2011/07/scsi-and-usb-hard-drive-tests/

Basically under AmigaOS 3.9 you top out at 6MB/sec using the Deneb in DMA mode with a USB 2.0 hard disk attached.  Under AmigaOS 4.1 Classic with Deneb in PIO mode you top out at 5.4MB/sec.

With the Cyberstorm PPC SCSI controller and a Barracuda 9.1GB 7200 RPM UW SCSI drive I topped out at 15MB/sec on both AmigaOS 3.9 and 4.1 Classic, with 4.1 Classic coming in significantly higher at lower buffer sizes.

I'll update the test later with the Deneb in PIO Mode on AmigaOS 3.9.

CPU usage results are also there...

Is this version of Fast-ATA for A1200 compatible with Lyra KB adapter?

Can anyone shed light for this matter please?

[amigakit]

It will be compatible if you raise the FastATA with some Kickstart ROM sockets (using them as risers):

Or use the BVision Kit:

[Bamiga2002]

Ok thanks for answer. But will the rom risers destroy compatibility with a Mediator then?

[pan1k]

Which is faster, FastATA 4000 or Buddha IDE?

Does anyone have a rough idea of when Jens IDEFix-SATA device will be released and how it will compare speed-wise with the FastATA devices?

Depending on the time frame I might hold off on getting a FastATA and wait for the IDEFix-SATA as an one of those+SSD+Indivision MkII+Blizzard/060 would make for a dream A1200 wedge WHDLoad machine.

Not forgetting to add my currently unused HxC floppy emulator and also a Kryoflux adapter (My next purchase methinks) to complete the perfect "under the TV machine".

Anyone want to buy a kidney? I have two!

Stock of the new version of FastATA 1200 MKIV in confirmed in transit to us now and will be at AmigaKit.com in a few business days time.  Pre-ordering is open at the moment.

We will also receive new stock of Mediator 1200LT4 and Mediator 1200TX with this batch.

Ideal upgrades for the new AmigaOS 4.1 Classic as well as AmigaOS 3.x

[Bamiga2002]

I'm curious to get an answer if I buy this new Fast-ATA for my A1200 will I be able to use BOTH Mediator & a Lyra KB adapter with it? Because with the older MK-III I was unable to do so.

[amigakit]

Yes this should be possible, you could use one set of sockets to raise the FastATA 1200 then use low profile IDE cables as they will push against the back side of the Mediator.  This is the same scenario as the older MK-III.  Dimensions of the board have not changed in this new model.

[amigakit]

Stock of the new version of FastATA 1200 MKIV has just arrived in the last hour and is now in stock.

We have also received new stock of Mediator 1200LT4 and Mediator 1200TX with this batch.

Ideal upgrades for the new AmigaOS 4.1 Classic as well as AmigaOS 3.x

All pre-orders will be processed in the next business day.
