Marius Posted February 12, 2014 Share Posted February 12, 2014 Atari 800XL, U1MB, IDE 2+ DOS writing: 53.26 KB/sec DOS reading 59.92 KB/sec You need to specify what the density of the disk was, and these benchmarks need also be done with the same tool. And even then... There can be a huge difference between one CF card and another. Besides that, I love IDE+ Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted February 13, 2014 Share Posted February 13, 2014 The 60Hz vblank probably slows the NTSC performance a bit. Quote Link to comment Share on other sites More sharing options...
+Stephen Posted February 13, 2014 Author Share Posted February 13, 2014 OK - now we're smoking. Anybody who questions "why PBI?", here's the reason. This is using the file system BTW, which makes it even more impressive. SIDE2 + U1MB in a PAL 130XE. I'm using a Transcend 2GB module, SDX 4.46a, 512bpp partition. Top one is without screen DMA, bottom is screen running. 100kB/sec is just around the corner. Can someone beat this benchmark? Quote Link to comment Share on other sites More sharing options...
bbking67 Posted February 13, 2014 Share Posted February 13, 2014 Isn't the SIDE just a cartridge? I thought PBI inferred making use of the proprietary 800xl connector? I know many pins are common... very impressive speeds. Now I have to get one. Quote Link to comment Share on other sites More sharing options...

Incognito in an NTSC 800, and IDE 2+ on a PAL and NTSC 130XE. Honestly, I expect all 4 speeds to be the same. Quote Link to comment Share on other sites More sharing options...

flashjazzcat Posted February 13, 2014 Share Posted February 13, 2014 Isn't the SIDE just a cartridge? I thought PBI inferred making use of the proprietary 800xl connector? I know many pins are common... SIDE isn't PBI; it just maps the IDE registers in the A8's memory. Regardless of how you go about reading and writing to these, it's still parallel IO. Ultimate's PBI BIOS emulates an OS-compliant PBI/ECI host adapter. Regardless of the implementation, what we're essentially comparing is SIO and PIO. IDE Plus 2.0 has a 16-bit IDE data register, so runs the disk in 16-bit mode. SIDE, meanwhile, has an 8-bit data register and runs the disk in 8-bit PIO mode. So, while the differences are subtle, this might account for slight variations in the speeds of the two adapters (since the firmware of both uses unrolled loops when reading and writing). I'll post benchmarks when the new drivers are released. ATR performance in the new PBI BIOSes is somewhat improved, but HDD partition performance remains broadly unchanged.

+Larry Posted February 13, 2014 Share Posted February 13, 2014 OK, here are some of my pets' tricks... All tests with MyDos 256-byte sectors, soft OS unless noted otherwise (Write, Read, Average), Screen ON. #1 MyIDE-II Hard Drive on CF at 1.79 MHz 17, 24, 20 KB/s #2 MyIDE-II Hard Drive on CF at 7.16 MHz 42, 76, 59 KB/s #3 MyIDE-II SRAM ramdisk at 7.16 MHz 71, 88, 79 KB/s (about 30% faster than CF) #4 System Expanded ramdisk at 1.79 MHz 37, 39, 38 KB/s (these numbers are basically identical with what you get on a stock Atari) #5 System Expanded ramdisk at 7.16 MHz 178, 163, 171 KB/s #6 System Expanded ramdisk at 14.32 MHz 491, 327, 409 KB/s (picture attached) A few notes: The soft OS lets the XL14 "stretch its legs" -- accelerated BASIC is at least 25% faster when running from ram vs. rom. SDX runs slightly faster with 256 byte sectors. Quite a bit faster with 512-byte sectors. MyIDE-II will not run at 14 MHz, but runs fine at 7 MHz. Ditto with IDE+2. Long story short, the XL14 at 7 MHz makes a very desirable package. One other note -- a MyDos ramdisk is always SD. -Larry 3 Quote Link to comment Share on other sites More sharing options...

I'm pretty sure the results you posted are not in the order Read, Write, Average; but in the order Write, Read, Average. Am I right about that?
