Has anyone got any idea what the transfer rates are for Amiga to SATA?
The way I see things for getting SATA to work on my A4000D there are several options
1. A4000D standard ide plus SATA adapter
2. A4000D FastATA MKV plus SATA adapter (AmigaKit)
3. Cyberstorm MKII SCSI plus ACARD SCSI to SATA
4. Z3 Fastlane SCSI plus ACARD SCSI to SATA
5. Deneb USB plus USB plus SATA adapter
but which is the best route bearing in mind transfer speed, ability to boot from SATA and cost.
On my A4000 I am using an ACARD UW-SCSI to IDE, then an IDE to SATA with a two terabyte drive:
http://reva.xtremeunix.com/Images/4.jpgThe IDE to SATA is on the back of the drive sled. The depth of the CD ROM area on an A4000 is a little bit limiting, of course.
On my A1200 I am doing the same thing, but the adapter is narrow SCSI to IDE to SATA. The drive in there is a 500 gig drive. Both drives are 5900 RPM Seagate LP drives, which is particularly nicer for the A4000 since that's running off of the stock power supply.
I am using the SCSI to IDE to SATA because I had been using SCSI to IDE and didn't want to spend the money on a new adapter (which work fine - I use a few SCSI to SATA elsewhere). The best place to put the drives, of course, is on the fastest bus you can. On my A1200 it's on the Blizzard 1260 SCSI and on the A4000 it's on the CyberStorm SCSI.
It's nice to be able to use the LP drives. I have a 500 gig on the A1200 and a 2 TB on the A4000.
Maybe those who have got SATA working could post their solution plus transfer speed.
Well, both machines are actively compiling so the speeds might be higher if other things weren't going on, but I'm getting around six megabytes/sec read on the A4000 and 4.5 writing, and four megabytes read on the A1200 and 3.5 writing. This is with NetBSD; I'm sure AmigaDOS is a bit more efficient.
