Okay Brian thanks for the info. I knew the multiple harddrives would
increase performance for daw's like Sonar on pc, wasn't' sure if it applied
to the Mac too. Now I know it works the same.

Onderwerp: RE: Texas Instruments firewire iMac

The multiple hard drive thing applies to all DAWs. It is to improve
performance.

With mechanical hard drives, when you ask them to load a file, there is a
short delay while the hard drive locates the data. Inside the hard drive, of
course, there is a magnetic head that must be moved to a specific position,
and the spinning platter that the head reads must rotate around to the right
position. The delay is very short (measured in milliseconds). For a single
file, this isn't that bad. If the computer must rapidly skip back and forth
between many files, over and over, though, a lot of time is wasted with the
hard drive repeatedly trying to move between files.

When using DAW software, a lot of data is streaming off of the hard drive,
anyway. Each track of audio is stored in one or more files, and so, as you
are recording/playing more tracks, the hard drive has to waste a lot more
time seaking around for files. Meanwile, the computer is also commanding the
hard drive to seak to other locations in order to locate and stream files
for your software instruments, to load/unload operating system files, and
more. When you use two hard drives (1 for your OS/programs and 1 for your
audio data), you split this work up a bit.

So, using two drives can dramatically increase performance. However, it
doesn't always increase performance. Someone that uses a lot of software
instruments will notice a big gain. Someone that is just recording audio
won't notice as big of a difference.

Of course, solid state drives don't have any delays associated with seaking.
If you're using an SSD, you can usually get away with a single hard drive.
However, this only applies if you're using SLC type SSDs, as the cheaper MLC
drives have very slow write speeds. SLC drives are way too expensive right
now for most people to use for everything. I use a MLC type SSD in my DAW
for the OS/software drive, as it significantly speeds up boot time, loading
programs, and loading plug ins. Faster plug in times, in particular, mean
that Sonar and PT projects load more quickly.

So, you could still get pretty good performance with a single drive if you
intended to mostly record audio, with only an occasional software
instrument. You could still use software instruments, even with a single
drive, but the performance of the system would be affected.

It is best to have two drives. A hard drive is such a cheap thing, that it
makes a really good upgrade for a DAW to have two instead of one. I'd be
concerned about buying a computer for use as a DAW where I couldn't use two
at full speed. If you can't on the iMac, for example, you might be fine for
a while, but you might not even have the option to upgrade later.

Of course, it might turn out that, with an FW800 hub, you could run an
external Firewire drive and a Firewire audio interface at the same time.
Thing is, I just don't have access to an iMac to test. I didn't want to
experiment, so I went with the Mac Pro. I know that the Mac Pro works, and I
have bad memories from years back when I wasted time trying to build my own
PC DAWs, and trying to work out all of the subtle conflicts between chipsets
and other components. I just wanted something stable.

If one of you on the list is willing to go for it, get an iMac. Get a
Firewire 800 hub. Connect an external Firewire drive and your M-Audio
Firewire interface. If it doesn't work, you have 30 days to return the iMac.
You might waste some time, but you might save some money. Others on the list
need your research, though.

Is it necessary also to have more harddrives when using a Mac with Pro Tools
only? Like it is for Sonar I mean.

No, that is very good. If it simply said OHCI compliant, that would be bad,
as that would be a way of saying "generic Firewire." Generic usually isn't
stable enough.

OK. Well, then. Let's hear it for the iMac. Of course, any Mac will run both
OS X and Windows, but, now we know, that Firewire interfaces will work in
Sonar, too. I haven't seen a system yet with TI Firewire that didn't.

The only obstacle that I can think of now regarding the iMac is the single
internal hard drive. You can attach an external drive, either USB or
Firewire.

USB isn't a good option, since USB data transfers can't use DMA, and thus
will drain processor resources, and will transfer more slowly than Firewire.

The iMac has only one Firewire port/channel, though, so it would be
necessary to chain an interface and a hard drive, in order to use both at
once. The iMac's Firewire bus supports Firewire 800, which is more than
enough for an interface and hard drive. However, most interfaces, the
ProjectMix included, will only run in Firewire 400 mode. Firewire 400 only
has enough bandwidth to run a single high quality 7200 RPM drive at full
tilt. Not sure if, when a Firewire device runs at FW400, it slows all other
Firewire devices down to FW400, also. Might be possible to get around those
limitations with an FW800 hub. In some cases, though, the limitations
wouldn't make a difference. For example, if you're mixing, then you're only
monitoring one stereo stream of audio via the ProjectMix, so it doesn't need
much bandwidth, leaving the rest of it for the drive. However, if you try to
track 16 inputs at once, then 16 inputs come in from the ProjectMix, and
then must go out to the drive, plus the playback for any tracks already on
the drive. That could get rough.

So, for now, it seems that someone can use an iMac with a M-Audio USB
interface and a Firewire hard drive, in order to get good performance from
both PT and Sonar. The issue isn't as clear if a Firewire interface is used.
It should be fairly good, no matter what, but it would be good if we could
figure out the bandwidth limitations. A 27 inch iMac would be the best deal
for most people planning to use MPowered or LE.

Subject: Texas Instruments firewire iMac

Hi,
My brother checked the firewire controller in his current model iMac with
i7. He dit it under Windows and said the following is mentioned for the
firewire controller:
"Texas Instruments OHCI compatible".
So TI as well as the OHCI compatible are stated there. Is this good or bad?
Since Brian wrote the OHCI compatible isn't good.
Don't know if Apple has different configurations for different countries,
but this iMac is bought in The Netherlands Europe. Perhaps if there will be
new models later this year they will have other hardware again.
Hth,
Ronald

TI Firewire means that the Firewire controller in the computer is made by
Texas Instruments, or TI for short.

When running in Mac OS X, I don't know of a way to find out the specifics
about the type of controllers and such that are in your computer. Apple
doesn't try to show people that information.

The only way that I know of to find out is if he is running Windows inside
BootCamp. If so, on Windows, he can go in to Device Manager. Under IEEE1394
Controllers, the Firewire controller will be listed. TI controllers say
something like Texas Instruments Firewire. If you see something else, like
OHCI compatible Firewire, VIA Firewire, etc, then we probably won't be able
to use it. Those controllers never seem to work right with audio interfaces
in Windows.

Hi,
What is "TI Firewire"?
My sighted brother has a current i7 iMac but isn't into music creation and I
think doesn't use Firewire. Is there some way I can check with him anyway?
Like to help if I can.
Cheers,

Yeh. It is particularly confusing to blind people when I tell them that the
27 inch iMac is probably the best value for high performance. I know that
they all think "but I don't need a 27 inch monitor." The thing is, though,
they will need some sort of monitor , if not because a Mac won't run right
without one, there is the benefit of making it possible for others in your
session to see what you're doing. 27 inches seems a bit excessive, but,
since Apple sells many of the exact same panels, rather than many different
monitor options, they get the panels at a good price. The LED panels in the
iMacs are extremely good quality. I wouldn't suggest that a blind person buy
such a display separately, but, when included with an iMac, you're getting a
really good deal.

Hi Brian,
Also came to the conclusion that an iMac would be a better choice. I always
refused to pay for a monitor thats attached to the iMac which I don't even
use, but it's the best option I think now for all the reasons you have
mentioned too.
The new Mac Minis are more expensive than before. The cheapest is now 800
euro and the server even more than 1100 euro. That is even more dollars.
Pretty hefty prices.

Ronald

Hi.

I anticipate that many people will have this thought, wanting to use the
Mini, since it seems like the most inexpensive Mac. It isn't a good idea, in
most cases. Mostly, the cases where it is a good idea involve you already
owning one. I wouldn't buy one new for the purpose of running Pro Tools.

The Mini can be an inexpensive computer. You can get one for about $700.
Just add your own keyboard, monitor, and, optionally, speakers, and you're
ready to go with an inexpensive Mac. That's particularly a great deal if you
already have an extra monitor, keyboard, and set of speakers. However, as
has been pointed out, this is only the base model. It has limitations, such
as only 2GB of memory, and a single laptop-type hard drive running at 5400
RPM.

As has also been pointed out, you can upgrade the Mini. Apple has a second
model, intended for use as a small server, that includes 2 7200 RPM hard
drives. That would help a lot for our purposes. However, that model starts
at $1,000. You'll need to buy your own copy of OS X, s adds about $30. In
order to provide the second hard drive in this model, the optical drive has
been removed. So, you'll need to purchase an external optical drive $50 to
$100, depending on what you get. This Mini comes with 4GB of memory, which
will be fine for tracking/mixing. If you plan to sequence a lot with
softsynths, though, you'll want 8GB, which adds another $400 to the price.
You still need a monitor, keyboard, and speakers. So, a Mini, with dual 7200
RPM drives, your own copy of OS X, external optical drive, a basic LCD
monitor, full Apple keyboard (you won't want to use a PC keyboard with Pro
Tools), and basic multimedia speakers will cost about $1,300. If you
upgraded the memory to 8GB, that increases the price to about $1,700. What
happened to that $700 computer? Upgrades.

So, if you'd need to spend $1,700, to pimp your Mini, what else could you
get for that price?

For $1,700, you can get a 21 inch iMac. It still will use a Core Duo
processor, but will run at 3Ghz, compared to 2.6Ghz in the Mini. It has 8GB
of memory. It only has a single internal drive, but it is a full desktop hd
running at 7200 RPM, and is 1TB, twice the size of the Mini's largest laptop
drives. The monitor is built-in to every iMac, and you're getting an
extremely high quality 21 inch LED display, not a cheesy $100 craptastic LCD
from the local computer store. An Apple keyboard comes standard with the
iMac, as does the built-in optical drive that you'd be purchasing separately
for your Mini. If you want a semi-portable solution, an iMac is fairly good
for that: computer guts and screen are built in to a single frame, so that
cuts down on the components and cables to transport.

If you want more from the Mini, you're out of luck. That $1,700 package is
as far as you can upgrade your Mini. The iMac still has room, though. You
can upgrade the 3Ghz processor to 3.3Ghz for another $200. You can upgrade
the 1TB hard drive to 2TB for $250.

So, the $700 Mini is a good deal, but only if you're planning to use the
basic Mini as-is. The upgrades cost too much. If you plan to need an
extremely high-end Mini, you'll get a better deal getting a lower end iMac.
Since the basic Mini is not enough for any serious Pro Tools work, I'd
suggest that people get iMacs, instead, and don't waste time upgrading the
Mini.

Bryan

Is the Mini Server usable as normal Mini? What are besides the missing dvd
drive the other differences between the server and normal one?
The two 500gb 7200rpm sound good. Need to get an external usb or firewire
dvd-drive though.

The mini server has two 7200 rpm disks and no dvd drive.  I was disappointed
that they didn't go to the i5 like the did in the MBP.  I think having two
500 gb 7200 rpm disks would work out well for audio productions.

Yeah.  That was quite a hassle for me.  I ended up getting a free monitor
from a friend because it had a busted back light.
