64 bits PCI on G4 working and confirmed!

64 bits PCI on G4 working and confirmed!
I put two SSD (Samsumg SSD 840 120 GB) in RAID 0 (stripe) mode connected to a Seritek 1eVE2+2

And it achieve a 190 MB/s of transfer rate!
This is clear over the 133 MB/s of peak transfer rate on the 32 bit bus. So the card and the PCI bus was working at 64 bits!
I know this is far from the max peak transfer rate on the 64 bits (266 MB/s) but the working 64 bits PCI on the G4 are at last confirmed!

very cool.. taking g4s into the next level -afro-
i will see about testing a highpoint pci-x raid controller
wait -- how did u implement the raid0?
it says its supported by third party software??
are u booting from the raid0 too?
my sawtooth g4 is much much faster over pci 32bit sata with a normal seagate sata2 drive
i will have to test the acard 32bit 6890m hardware raid card very soon... maybe i will buy a few new ssd just for test then return LOL

The average PowerMac user in 2014 spend 10 Euros on a chinese generic SIL 3112 33Mhz pci for 2 sata port for use it at 40/70 Mb/s. It is required to flash it on a PC. I am afraid to ask how much did you spend in this SATA interface.

From the years I studied Video Edition, DV codec video "waste" 25Mb/s for every layer. 190Mb/s means 7-8 DV video layers... 8) -afro- 8)
In Audio is a Quantum Leap. For sure it let you use in Logic 8-16 tracks in 192kHz audio.
I was afraid after hearing DieHard and others that ANY pci-to-ide or pci-to-sata interface "eats" too many bandwith that could lead to audio drops.
I have the feeling that a PowerMac with all the pci ports ocupied is less stable than one with a AGP card and a sound card. Maybe is my PSU. Maybe less component lead to less possible failures.
Show us your G4 setup (I guess is a MDD dual at 1.48-1.8), yours pci cards used at the same time. Maybe is just a question of get rid of garbage pci cards.
I readed somewhere that in Magma chassis setup you should not install a pci to scsi-ata-sata in the chassis. It should be installed inside the PM.
In the past I filled every pci socket on my GHz dual. Now I feel a barebone G4 Digital Audio is enought to 24 tracks@24bits@44.1kHz with the stock ATA-66 for audio and the boot disk under the CD. (In this way you can access later the IDE-0 disk booting in Transfer Disk Mode)
On the other hand given the price of the seritek and the price of 2 SSD@120gb perhaps for a RAID setup is cheaper 2 (or 3) 33Mhz sil 3112 pci cards.

pretty sure sata1 vs ATA-66 there is no comparison.. in my opinion any g3 or g4 will run better +faster using pci-sata card
for boot disk rather then using the ancient ATA-66 IDE connection.

^ according to this article 66 means simply top speed of 66mb/s, 33= 33mb/s, same for 100, 133 etc
my sawtooth g4 AGP 450mhz runs so much nicer now that
i cloned the drive to the sata2 hard drive connected via PCI-SAta interface.
ata-66 ancient technology man... we are talking what.. 1997? and its the biggest weakness of the machine imo.. the weakest link.. stopping performance..
im sure new young techno-kids would say the weakeest link is the cpu .. for hte years 2000-2005 the slowest part of a computer
has always been the disk performance... now that we have sata2 + sata3 capable hard drives... why would u run ata-66?
they outperform ATA-66 by so much

lol Quantum fireball. i havent heard thse words in forever;) lol
according to these articles
ata-33= 1997
ata-66= 1999

I keep my Sata drives on intels. Ata and SCSI on PMs
