PFS3 setup and configuration

I believe this is what you're looking for, no ?

@Peter:
I guess you can set max. PIO mode for all drives. To be sure just ask Elbox about.

Later on in the User Guide on page 10 it states that, "Note: the booting hard drive should be connected to the Primary Port as a MASTER (SINGLE) Device"

I break that all down to - Set Booting CF CARD to PIO 0 on Primary Port as Master.

I guess I could play around with the PIO Settings but from what I have read it seems that this is the way it should be set up... or am I just getting it wrong?

One thing to note is that, of course you can have three other additional IDE devices attached all running in faster PIO Modes but you need to realise that each 3.5 IDE CF adapter needs Power and takes up a fair bit of space in a standard desktop.

AFAIK the FastATA for A1200 connects to the internal IDE port. This means after power-on it needs to be supported by the scsi.device in Kickstart which can only do PIO-0. Only after the FastATA software has been loaded from startup-sequence faster PIO modes can be used.

So nothing hinders you to use a faster mode for the boot drive. Only the hardware supports PIO-0 for backwards compatibility.

Hello dudes,

I was wondering if I should move from SFS to PFS3 (as everybody is talking about it) but seeing those benchmarks makes me hesitate to take the plunge.

I own a cheap 4GB CF on my A1200 With a Blizzard 1260@50Mhz and Sysinfo report +2100 on the internal IDE controller with SFS. so ?

you can move to pfs3 because is lot faster than SFS or FFS

on the other way changing the filesystem will not improve tha maximum read speed that reports sysinfo

if you want more speed on internal ide get a new 2.5 hardisk they are much faster than any cf card + adapters
new 2.5 ide hardisks speeds are about 2.7 or 2.8mb sec

No, I'm looking for a good compromise of access time/read speed, but from the Peter result it seems that for the read speed SFS is faster...
We have the same computer, 600MB/s seems huge to me (even if we don't have the same CF brand)...
Someone has done a comparison table between SFS/PFS3 ?

A question : "DS" stand for ?

[Cammy]

The only comparison I have done was formatting a 4GB CF card into two even 2GB partitions, one as SFS and the other as PFS3, then I installed the exact same AmigaSYS setup on each one of them. Then I booted each one a few times and timed them, and the PFS3 partition finished booting two seconds before the SFS partition did in each test I did.

This was on an A1200 with an 8MB RAM card.

Sysinfo reports are reliable ?

So here is the comparison between SFS/PFS3

On my Amiga 1200 + Blizzard 060 Phase 5 @50Mhz

CF Kingston 4GB
With the same amount of data [50% Full] (I did restore my datas)

SYSINFO:

PFS3060ds: 2,184,533 B/s
300 Buffers

SFS: 2,184,533 B/s
100 Buffers

:P

I think they both reach the max transfer ? right ?

SysSpeed 2.6 on SFS:

Drive Results in Ops

Create - 226
Open - 381
Dirscan - 1199
Delete - 51
Seek/Read - 593

Drive Results in MB's

Create File - 1.22
Write File - 1.24
Read File - 1.53
Raw Read -1.54


SysSpeed 2.6 on PFS3:

Drive Results in Ops

Create - 400
Open - 548
Dirscan - 2129
Delete - 481
Seek/Read - 1132

Drive Results in MB's

Create File - 1.35
Write File - 1.13
Read File - 1.53
Raw Read -1.53


So what do you think ?

[Toni Wilen]

SysInfo speed test accesses the device directly, filesystem has no effect on results.

CF cards are fast enough (at least more expensive ones) but perhaps some of them don't like old PIO modes because CF card in SCSI adapter can have speeds over 7M/s. (Make sure you have fast enough card, CF cards are using same speed rating as CDROMs, 1x = 150k/s)

Note that you can't directly compare IDE speeds without having exact same hardware, IDE speed (Gayle access speed) depend greatly on used accelerator model. Blizzards for example are (unfortunately) relatively slow.

Toni, the results are mine one the same Amiga, the same CF.
I have just switched the CF between the 2 test (and the CF is also the same with the same amount of data)
