I Got more than 80MB/sec on a Ultra 320 10k RPM single SCSI hard drive
attached on a U320 controller....so YES, IDE is cheaper but still far
long from SCSI performance... And I even didn't try 15K rpm drives...

Moreover IDE raid is not sompliant to standard, so forget this
####...Everything which is not standard is not reliable... So I hope
you won't lose any video on your VT[3]...

Depends on what you are going to use your computer for.
SCSI is very nice, if you many transfers going from multiple disks at the same time, it is then you start noticing the weakness of the ide bus. If you do video editing and such, then you would benefit alot from a faster disk.  :-)

I i could afford it, i would have only scsi in my system, but sadly im poor so i gotta settle with ide disks.   :cry:

Why not try SATA-IDE 10K RPM drives?

My single UDMA 7200 RPM 80Gb yields ~55Mb/s, (without taking RAID into an account i.e. dual 7200 RPM 80Gb setup).

Most of IDE-RAID IDEs have RAID 0, RAID 1 and RAID 1/0.

PS; Mean time of error is generally lower with IDE HDs than SCSI types (i.e. but you get what you pay)...

I feel that HD speed is one of the biggest bottlenecks in my Amiga setup. Sure, the Z-IV busboard and the CV64/3D can hardly handle Doom. Sure, the 060/50MHz isn't exactly top of the line anymore. But all file system operations are a real pain. Sure, my HD needs a good defragmentation but at about 1.8-2.0MB/s (SysInfo) that's what slows things down.

I remember when Amigas booted in just a few (around 10) seconds. My Amiga takes around 30-40 seconds to boot, then load ToolManager graphics, backgrounds... All file requesters are dog slow and thank god for MCP's font cache.

I'd switch to SCSI any day if I could afford it!

when i still had my machine, i used to have the boot partitions and system apps on a 5Gb IDE drive with 256k cache (ok not alot of cache by todays multi megabyte standard but its was fast when i bought it), but the trouble was, the digital broadcaster NEEDED scsi for video recording / playback. so fine fine saved up and got a PPC card with ultrawide drives. and thought my machine takes SO long to boot. PPC drivers, GFX card drivers, librarys etc etc. and i had so much space that wasn't being used. so shuffled the boot partition and apps onto one of my video drives.

ok so FFS isn't the most effective filesystem around, but my boot times were halved, and heretic2 took about half the time to load levels... would NEVER go back to IDE on the amiga.. but thats all my CD/SX32 has.... on the PC i appriciate its a different matter, what with UDMA33/66/100/133/150. and as for that IDE raid stuff someone was talking about. thats great! and what amiga is that on? its not. so not relevant.

plus compairing a raid system to a single disk is a touch unfair. i was well happy with 25Mb a second (untweeked - not playing around with phase5's scsi tools) on my amiga. 36Mb tweeked. :-D

I have a catweasel/Buddha Ide controller on my 4000 and have had problems with it. What kind of speed does this controller have? I also have the Cyberstorm MKIII 060 with the SCSI ultra wide and since I have had problems with the BUDDHA I was just going to change over to the SCSI ultra wide. I have one hard drive in it that is scsi and just need to get the correct cables to get it working.

We used to have everything on SCSI for speed but these days IDE is more than fast enough.  Of course if we are talking Amiga IDE that may be another matter.  Interestingly the DPS Personal Animation Recorder, a device that needed superfast access used a dedicated IDE setup even if in those days SCSI was the norm for big box amigas.

That's impossible tintin! Nothing can even be 'fast enough', let alone 'more than fast enough'!

Crazy talk! :crazy:

Yes HD speed DOES MATTER!

Even if you use your Amiga only for DTP or Gaming HD speed makes a difference.

Internet Browsers use cache and the faster the HD, the better the performance of the browser will be.
(unless you use a 3200 modem :-) )

Games load faster, Images load faster, Videos load faster - and even better, huge videos will paly really smooth!

As for SCSI, I believe that nothing is better than a Seagate Cheetah, but if you dont have the money for SCSI you could try UATA (or SATA). Today's IDE HDs are fast enough for any use.
