Promise Ultra100 TX2 on P3B-F Test Results
Hello,
I have seen several people ask if a controller card is worth having. I just thought I'd share my experiences with one. I have a home built. It uses Asus P3B-F 1 G PIII using Abit Slocket II 384 Meg RAM ATI All in Wonder Pro 16 Mb TechRAM Ultra2 DC-390U SCSI 9 Gig IBM connected to SCSI Maxtor 120/8 Gig Master Maxtor 30 Gig Slave I bought the card because I was having streaming audio pause when I opened my email program (Pegasus). It would start back up again but the pause was driving me nuts. I was told on Google that upgrading to an ata 100 drive would stop this problem. It hasn't. Yes, DMA is on. I was trying to decide whether to keep or sell the card so I ran a few simple tests. I did a test moving and copying a 4.27 Gig folder with 698 files and 170 folders in it. Mostly avi and iso images. First using the Ultra100 Copying from G (30G) to F (120G) 4:33 Moving from F (120G) to E (9G SCSI) +-10 min. 15 sec window for error. Moving from G (30G) to F (120G) 4:21 WithOUT the Ultra100 Copying from F (120G) to G (30G) 6:37 Copying from G (30G) to F (120G) 6:26 Moving from F (120G) to E (9G SCSI) +-11:16 Moving from G (30G) to F (120G) 6:29 Times are in minutes:seconds. I ran it to my SCSI to see what the PCI bus would do to the times. The SCSI card is supposed to be fairly fast, 20 MB/s. The SCSI drive is an IBM 9.1G? 50-pin narrow. I don't really notice any real increases in speed in my daily usage. I haven't played with virtual dub with the card enough to know if it makes a diff. I had no problems capturing video without the card. I googled and found a link to a BIOS update that allows my MB to support DMA 100. http://tinyurl.com/lv8x I may try that. Kind of scares me to put a third party BIOS into my system. Anyway I hope this info will help someone out. I know my tests are not the best and there are better. Heck, I was using my grandson's Hot Wheels stop watch so they have to be close. LOL Steve My real email address is dealsgalore[A-T]earthlink.net www.cheap-land.com |

LOL Were the hard drives on the same IDE channels or on different channels when testing with and without the Promise controller? *TimDaniels* |

I only have one ata cable. Maybe I should get another one and play some more. ;-) Sorry, I forgot to add that information.

If you have the time and money, try seeing if the time is the same for a "round" cable as for the same length ribbon cable. Hey! And while you're at it.... :-) *TimDaniels* |
