Just wondering if these speeds look normal for a windows 98 system with a promise sata 150 with an ssd drive. reads seem to top out at 71 mb/s and writes around 36/mb shouldn't they be over 100?
ssd is a brandnew sandisk one that had dram cache
I think 150 rating is for two drives in Raid, or something like that.
What's the speed of the CPU?
Not only the speed of the CPU, but the specs for the rest of the computer?
What CPU running at what speed?
What motherboard?
What front side bus speed?
What RAM and speed and timings?
What speed is the PCI bus running at?
What is the PCI latency set at?
Is the slot the SATA card is in sharing an IRQ with anything else?
Is the driver for the SATA card installed?
What updates have been installed for Windows? Is the unofficial service pack installed? If so, which release and what parts are installed?
Here's my S150 Atto test on my M930LMR with a P4 2.8/512/533, DDR, SiS 645 chipset, an Silicon Power Ace A55 128 gigabyte SSD, and Windows 98 SE:
"I'd rather be rich than stupid" - Jack Handey
And here's my S150 TX2 on a PIII 1.4GHz, 512MB PC133, i815, Kingston 120GB A400 SSD:
It looks like my S150 TX2 is sharing an IRQ with the USB 2.0 PCI card, but apparently that doesn't seem to matter.
As long as you are not using those two devices simultaneously it shouldn't matter. However sharing IRQ between USB 2.0 and SATA Controller is not a great idea. I would check that and DMA transfers being enabled.
Pentium III 900E, ECS P6BXT-A+, 384MB RAM, NVIDIA GeForce FX 5600 128MB, Voodoo 2 12MB, 80GB HDD, Yamaha SM718 ISA, 19" AOC 9GlrA
Athlon 64 3400+, MSI K8T Neo V, 1GB RAM, NVIDIA GeForce 7600GT 512MB, 250GB HDD, Sound Blaster Audigy 2 ZS
What CPU running at what speed? celeron 1400mhz
What motherboard? gigabyte GA-BX2000+
What front side bus speed? 100mhz
What RAM and speed and timings? 2x256mb pc100 cl2 ecc
What speed is the PCI bus running at? should be stock
What is the PCI latency set at? also whatever is stock
Is the slot the SATA card is in sharing an IRQ with anything else? second to last pci slot it might be sharing not sure.
Is the driver for the SATA card installed? yes the last official one from the promise website.
What updates have been installed for Windows? Is the unofficial service pack installed? If so, which release and what parts are installed? just dx7

dma is turned on for the 2 cdroms but there is no dma option for the sata controler or the ssd as far as i can tell.

I'm pretty sure the controller enables DMA by default.
It does

Pretty sure its because it can, in theory, shuffle about 150 MB/s of data per channel (or 1.5 Gbit/s as per the SATA revision 1 specification).
Now this would be more then the normal 133MB/s 32-bit PCI bus can handle.
But I suppose that if you copy between the 2 channels on the TX2 you could use all the bandwidth.
Now I say I'm pretty sure and that's because most cards from from Promise are named according to interface speed and number of ports =)
Like "Ultra 100 TX2" has 2 channels of ATA100, "Ultra 66" is ATA66, etc.
ok so it looks like it is sharing an irq with the usb 2 card. and even after shuffling cards around the irq follows to sharing with 1 of 2 listings of the usb card. the gigabyte bios won't let me assign an irq to a slot just reserve one for the isa slot.
although after moving the card up 2 slots it greatly improved the write speed from 36mb/s to 73mb/s read speed only went from 71mb/s to 73mb/s
looking at mrz speed on a p3 1.4 with the faster 133 bus and newer 815 chipset him getting 90mb/s and repo man even on the way faster p4 seem to only read 90 as well so guessing that is the limit of these pci cards?. i'm guess i'm hitting the bottle neck of the older 440bx/pc100 interface now? or is there something more i can do to squeeze that 20mb/s out of the card

What motherboard are you using?
On some brands you can find what slots share IRQ with each other or something else.
Usually the AGP port shares IRQ with the closest PCI slot, 2 may share with 3 etc.
Like this from the ASUS P3B-F:
its a gigabyte GA-BX2000+ but there is nothing in the manual about that. the only thing that even says anything about irqs is it talking about what irqs are assigned to the serial and printer ports.
i've disabled both serial ports and the printer port since i have no use for those. i also disabled the second ultra 66 ide controller since that is pretty much pointless i'm only using cd drives on ide so the main ide controler using the intel chipset should be good enough for that.
i can't really use pci slot 1 since it covered by the gpu cooler. i put the aureal card in slot 2 since everything indicates its best to put that card there.
i tired shuffling cards between 3 4 and 5. i haven't really tired slot 6 id kinda like to keep that one free in case i want to use the isa slot at some point.
It could be that the polling rate of the USB card is slowing things down.
Is there a setting in the BIOS for PCI latency?
here is pictures of all the bios setting screens.
~70MB/s isn't all that bad. I don't recall whether I've seen more than that from 440BX. The best you can practically get out of PCI is 90-100MB/s. That is also all the bandwidth available to the southbridge with 440BX.

that's my thinking that now with some tinkering i got it to 73ish mb/s read and write that i'm probably at the bottleneck of this older chipset combined with a 100mhz fsb. it was def off when the write speed was only pushing 36mb/s installing stuff felt super slow.
if anyone has any tweaks or adjustments that they think might get it closer to the 90-100mb/s i'm open to try. i think i have everything setup right in the bios. i turn CL on the ram from 3 to 2. i turned on ecc since its ecc ram. i shut off printer and serial ports. i set the graphic aperture to 128mb. everything else i believe is stock.
I would try turning Delayed Transaction off, L2 ECC off and the ECC on the RAM off.
Try them one at a time.
You may be reaching the limit of that board, but I would think you should be able to get a bit higher.
Try without the USB 2 card installed as well.
