Fastest possible disk access in os9

hi there
as the topic says im interested in achieving the best possible disk speeds in os9 for use with old media programs.
i have resurrected an old g4 450mhz sawtooth that im using to run some old music production programs
im pretty sure that the disk speed is the biggest bottleneck on this machine.
Ive been looking into the following ACARD devices ive provided links to newegg
simple for the images + reference
ACARD AEC-6280M (4 CH IDE | NON RAID)
http://www.newegg.ca/Product/Product.aspx?Item=N82E16816123110R
ACARD AEC-6290M (2 CH SATA150 | NONRAID)
http://www.newegg.ca/Product/Product.aspx?Item=N82E16816123109R
ACARD AEC-6880M(4CH IDE RAID0/1)
http://www.newegg.ca/Product/Product.aspx?Item=N82E16816123007R
ACARD AEC-6885M (4CH IDE RAID0/1/0+1)
http://www.newegg.ca/Product/Product.aspx?Item=N82E16816123008R
ACARD AEC-6890M (2CH SATA150 RAID0/1)
http://www.newegg.ca/Product/Product.aspx?Item=N82E16816123111R
features booting into os9
my question is can anyone reccomend to me any other cards that i might find cheaply + available
that provide the following criteria:
a) bootable into os9
b) supporting SATA hard drive (so i can buy new hard drives in the future IDE are no longer available for purchase at my local shop)
c) hardware raid
d) supporting HFS volume visible to both os9 + osx
e) hardware raid dip-switchable from RAID0/RAID1 (RAID0+1 would be the ultimate)
f) PCI interface and compatible with all G3/G4 and also pci/pci-x based G5's
the 6890M seems like the perfect option for me but i have found that these items are now unavailable + sold out.
is there any other product that i can try to find under a diferent brand name ? i have read that acard did cards for sonnet/miglia/SIIG
that were rebranded... Im hoping someones already done their homework on all this stuff and can point me in the rigth direction
so i can get to using my programs + os to do what i love to do and stop worrying about technical headaches..
again obv this isnt my only computer but i like to use os9 for some programs + also its unique GUI environment!
fingers crossed

@brody
i actually own one i have it on the desk sitting next to me right now. its a silicon images controller with custom firmware to provide the mac compatibility... works great... but only provides 2x sata150 ports.. which is great in and of itself.. but doesnt provide raid to os9.. doesnt alllow you to combine the speed of two drives together undre os9... to achieve a speed comparible of sata II (sata2 or sata300)
@jon
yes i imagined that card would be the best bang for buck but again that card provides the ports for ide drives and doesnt provide the combination of more then one drive unless u were to use it under osx.. and then u could acheive this with softare raid from disk utility but wouldnt allow me to use two drives as one volume under os9
ive actually been in touch with acard and they said they are out of stock completely on the AEC-6890M which is the card that provides RAID with 2x Sata drives for os9. im looking for a similar product to this.. that has the raid controlled by the card and not the OS.. configurable between RAID0, RAID1 and possibly even RAID0+1(which would require 4 drives tho, instead of just 2)
ive just got a response back from a calssified ad i posted to but had almost given up on after not receiving a response. the guy was on vacation;) anyways hes got a AEC-6880M which is the raid capable IDE Card.. for a good price.. the only problem is.. the availability of IDE hard drives.. they are all dying and i dont think they are making IDE ATA133 drives anymore.. ? does anyone know?

  • Fast User Switching-- Disk Access Error

    I have created a Standard User Account with no Parental Controls. I have not had any problems whatsoever logging in to iVisit (video conferencing) as an Admin, but when I log into the Standard account, and try to log into iVisit (using the same log in information as my Admin account, and this is what iVisit suggests I can do) I get the following error message when I click the log in button:
    Disk access error. Check free space and write permissions.
    I've tried logging out of my Admin account first, then logging into the Standard account before I try iVisit, but that didn't work. I've opened up the Standard account as much as possible (I think) to remove any restrictions, and even selected the option to allow user to administer this computer, but that didn't work either.
    Another piece to this puzzle, is that iVisit Help suggested that I install iVisit under the Standard User, just to be safe. But during the install process, the installer quits, and I get an error message that says it can't continue.
    Does anybody know what's going on? I really appreciate any help! Thanks
    Powerbook G4 1.33 Mhz   Mac OS X (10.4.3)   External OWC, 512 RAM, iSight

    I don't know anything about iVisit, but it sounds like it may not be behaving exactly as an OS X installer should — placing files in spots that only admins can access. I would try this as a next step:
    1. Uninstall iVisit.
    2. Make your standard account an admin.
    3. Try and install iVisit through the newly admin'd standard account. Hopefully this avoids the error/crash.
    4. Confirm that iVisit works through this account.
    5. Switch it back to a standard account and test again.
    I don't know if this will fix your problem, but it's worth a shot and may help narrow down the cause of the problem.

  • [SOLVED] Long time with excessive disk access before system reboot.

    I feel I would be grateful for some help here. It's my first go at Arch Linux having used Xubuntu for several years. It may be I'm missing something obvious but then I would be happy if someone could point me in the right direction.
    Problem: When I do a system restart by issuing
    $ systemctl reboot
    I get the following output

    However, after the last line is printed, the system does not reboot immediately but hangs for about 2 minutes with heavy disk activity. I can't say if it is read or write or both, but the led of my HDD is lit constantly. When this activity stops, the machine reboots.
    $ systemctl poweroff
    works as expected, i.e. shuts down immediately without excessive disk access.
    I see this behaviour both with the installed Arch system and when I run the live installation/recovery CD. It is also the same if I boot into the busybox rescue shell and then restarts the machine from there. It also does not seem to matter if any partition on the disk is is mounted or not, the behaviour is always the same with 2 min. heavy activity before reboot.
    System setup:
    Sony Vaio VPZ13. Intel Core i5 M460, 4GB ram, 2x64GB SSD in RAID0 configuration via bios setting (a.k.a. fake raid), partitioned like:
    windows boot
    windows system
    linux swap
    linux "/"
    linux "/home"
    So it's a dual boot setup with Windows 7.
    The raid array is assembled by mdadm, and I have mdadm_udev among my mkinitcpio.conf hooks (after blocks but before filesystems).

    Since I have used Xubuntu without hassle for several years, I first thought the problem may be related to systemd reboot and something in my system setup. But I have tried the Fedora 17 live CD and rebooting there works as expected. So, since it works in one systemd distro, it should work with Arch as well.
    Then I thought that it maybe had something to do with the raid-array, something along the lines of
    https://bugzilla.redhat.com/show_bug.cgi?id=752593
    https://bugzilla.redhat.com/show_bug.cgi?id=879327
    But then I found the shutdown hook for mkinitcpio and now I see that the array is stopped and dissassembled. So thats not the problem either. (Or thats what I guess at least.)
    Unfortunately I'm out of ideas. Any help would be grateful.

    It turned out that the magic word for me was "reboot=pci" on the kernel command line. With that option set it works lika a charm The machine reboots nice and clean.

  • Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

    Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

    Firefox consumes a lot of CPU resources

  • Time Capsule disk access SLOW!   2TB - Dual band

    I have a Time Capsule (2TB, Dual Band, Firmare at 7.4.2)
    Its been working like a dream, backing up 3 Macs for the last 8 months.
    I also use it for connecting two or three other disks via USB and then making those accessible over the LAN, and there is also about 100GB of data on the Time capsule disk itself that i use as a dump for files so i can get to them from anywhere on my LAN.
    Lately I started to notice EXTREMELY slow disk access, even when i am connected via ethernet (1000 base) - and equally when I am connected via wifi (n)
    for example, copying over a 2Mb photo can take minutes when it should take seconds.
    i've been trying to figure out whats going on here for a while and so i checked out the sizes of the backup files.. the sparseimages that time machine creates.
    one of them was nearly 1TB, while another was around 500GB and the other was around 120GB
    that plus my data meant there was only about 300GB free on the 2TB disk.
    I have a feeling the slowness could be down to extreme fragmentation of the drive... ??
    so i decided to dump the backup files and copy off my other data and do a erase of the disk and start again.. but get this.. i can't even delete the 1TB file ! I have been trying for about 3 days now and it just will not delete.. i get the Deleting msg box and it just sits there, literally ALL night...
    i know it isn't just hanging on the Mac (10.6.4) because deleting the other two images also took a long time (but not this long!)
    i can't just wipe the disk now because i can't get my other data off either.. I have tried copying it over the network and onto a USB disk connected directly to the Time Capsule, but 3 days later and i'm still copying files..
    to put some context into this, I copied over 1.8Gb today and it took about 4 hours...
    has anyone had this problem before?? what on earth is going on?? is it down to fragmentation, or something else?? the TC has been working fine up until a few weeks ago when i started to notice slow speed.
    any ideas ?
    thanks
    Adam

    if anyone ever has this issue ....
    it must have been EXTREME fragmentation. I bought another 2TB external disk, connected it to the TC, did a complete archive, which took around 24 hours... then i wiped the TC and put stuff back... it now works fine again...

  • Error "NOTICE: [0] disk access failed" during guest domain network booting

    Hi,
    Could you please tell me what is the problem with my configuration?
    I created guest domain on my T1000 server.
    As a disk I used disk from disk array: /dev/dsk/c0t18d0
    I added disk using commands:
    # ldm add-vdsdev /dev/dsk/c0t18d0 vol1@primary-vds0
    # ldm add-vdisk vdisk1 vol1@primary-vds0 myldom1
    # ldm set-variable auto-boot\?=false myldom1
    # ldm set-variable boot-device=/virtual-devices@100/channel-devices@200/disk@0 myldom1

  • Is is possible to access channels from a CAN database in labview with NI USB 8473s

    Hello,
    I would like to know whether is possible to access a CAN database, which is uploaded through MAX, in labview.
    More specifically, I have uploaded my CAN database in MAX and I want to have access to each specific channel in labview.
    i.e according to picture, I would like to have access  to n_Motor_InsRpm channel of E1_L0_1 (motor speed) in Labview, so I can set and transmit a speed value through CAN. Could that be possible with NI USB 8473 s? If yes, is there any simple example in Labview ?
    Thanks for your Help

  • No Longer Possible to Access iCloud Mail on Third Party Mac

    Something has changed recently. It is no longer possible to access iCloud mail on a third party mac via web browser
    This afternoon, I tried to do so on my daughter's iMac - and the system wanted me to set up iCloud rather than letting me access Mail (or any other iCloud services for that matter) instead. Tried different browsers, change of login account on the computer. All to no avail. Have to set up iCloud on the computer. Which means either logging my daughter out, or creating a whole new identity for the purpose. This entirely defeats the notion of the simple webmail interface - and indeed makes Pages, Calendar, etc inaccessible unless on your own computer, or one that you have used to set up an iCloud account. Not something that you want to do in an internet cafe or an airport lounge.
    Two sets of Chat Support sessions later, with the problem being hinted to be probably due to "my daughter's computer (!!???)", no satisfaction
    I am now in the airport, trying to still access my iCloud mail through a web browser. Same nonsense about setting up iCloud before I can access my iCloud mail via the web through a browser.
    Apple, this was one of the advantages of iCloud that I, as a regular traveller, have found useful in the past. Today I have wasted well over an hour on something that is clearly an error in the logic of how people will be using iCloud - possibly a "feature" of Mavericks?
    Please bring back simple and straightforward access to iCloud mail via web browser, so that I can once again access my mail from any third party computer.
    Thanks

    Excellent, well done. I have to say that talktalk were useless, they repeatedly sent me instructions for setting up an emil account and did not seem able to understand that it was the login that would not work. Thank you.

  • I'd like to know if it's possible to access an older version of a web page in Firefox.

    I'm wondering if it's possible to access an older version of a webpage I've since made changes to -- the site is through Livejournal.com -- in order to see the information that was on the older page. I'd like to keep it consistent with the new page, but am not sure how to do this. I very stupidly didn't save a copy of the old page!

    If you know where the page is at, I myself don't see any reason why you can't access it.
    The only thing I could think was if Livejournal.com had a lock on the page or if you had to sign-in and your u/n and p/w had expired.
    I'd say go ahead and at least try.

  • Is it possible to access a single Lightroom catalogue mounted on a shared drive from multiple computers, each with an individual Lightroom install?

    Is it possible to access a single Lightroom catalogue mounted on a shared drive from multiple computers, each with an individual Lightroom install?
    Thanks.

    No, Lightroom catalogs cannot be on a networked (shared) drive, and they do not support simultaneous multi-user access

  • Disk Access

    I am wondering about disk access I have a Toshiba 505-890 running Win-7
    I notice that I am getting a disk access about every second as per the disk access light
    coming on.
    On my Win XP mach I don't get a light unless the computer is doing something for the most part.
     Definitely not accessing every second.
    I was wondering if this problem is endemic to win 7 or some Toshiba program I have not removed.?
    If I put a clean install of win 7 will I still have this problem???

    This program is not giving me much info on what is doing the disk access.
    I have attached a pic of what it comes up with.

  • Windows 2008 R2 Hyper-V has really slow VMs disk access

    Wondering if anyone can help? I have noticed in a couple of Windows Server 2008 R2 Hyper-V scenarios, that the VM guests are often very slow. Disk access is especially slow.
    In one situation their was only a couple of guest VMs, and they were running of mirrored IDE HDDs.  Performance improved significantly when I used two mirrored SSD hdds instead.
    My other main situation is where the VHDs are stored on HP Lefthand P4300, over 2-nodes with 8 SATA hdds in each, using iSCSI.
    So I ran a few tests with robocopy copying 4-6GB of files (mostly large) or whole VHDs (40GB or more), using HP4300 SATA, a newer HP 4330 SAS, a THECUS NAS with SATA hdds,  and an SSD in a THECUS NAS, and local SAS mirrored hdds. All using iSCSI except
    the local SAS hdds.
    You can see from results that Guests run considerably slower than host. Any ideas?
    Sample data (although not always same background conditions of load etc):
    From within Guest direct iSCSI to same (from HP 4330): 34MB/s
    From other Guest using VHD (from HP4300) to direct iSCSI (from HP4330): 14MB/s
    From within Guest using VHD (from HP4330) to same: 9MB/s
    From within Guest using VHD (from HP4300) to VHD (from HP4330): 11MB/s
    From within Guest using VHD (from HP4330) to VHD (from HP4330): 19MB/s
    From within Guest using VHD (from THECUS SSD) to same VHD (from THECUS SSD): 18MB/s
    From within Guest using VHD (from HP4300) to VHD (from THECUS SSD): 13MB/s
    From within Host from HP4300 iSCSI to HP4330 iSCSI: 12MB/s
    From within Host using VHD (from THECUS SSD) to same VHD (from THECUS SSD): 40MB/s
    From within Host from HP4330 iSCSI to same HP4330 iSCSI: 232MB/s & 132MB/s
    From within Host from HP4330 iSCSI to HP4300 iSCSI: 40MB/s & 57MB/s
    From within Host from HP4300 iSCSI to same HP4300 iSCSI: 26MB/s & 47MB/s
    From within Host from HP4300 iSCSI to Guest VHD (from THECUS SATA): 15MB/s

    Hi aucj,
    I would suggest to use host level ISCSI connection then build VM on that ISCSI disk .
    please add more Vcpu for that VM then try to copy again (shutdown the other VMs ,in that online VM from one folder to another folder ).
    Hp4330 ISCSI connection is 1GB , right ?
    If yes , it should be with max 100M/s with the single ISCSI connection .
    Best Regards
    Elton Ji
