iMac i7 slow

Recommended Posts

Hello there

 

i have an iMac I7, the newest fastest one..

 

I have taken the Evan benchmark test and i can run around 75 tracks which is quite a lot more than my previous MAC (a G5 before intel)..

 

However the Imac seems slower.. I get a lot of "disk to slow" messages and another problem is that when I press play I sometimes have to wait up to 5 seconds before playback commences.. And this is with the simplest of arrangements..

 

Anyone heard about this before????

 

I record and playback to a partition of the internal HD (1 TB plenty of free space) Samples for virtual instruments run of a firewire drive .. I use RME FIREFACE USB..

I run the latest LOGIC and SNOW LEOPARD..

 

I did not have any problems like that on my way older system ..

 

Any help would be great

Partitioning the system drive is a bad idea in my opinion.

You're playing back and recording on the same drive, regardless if it's partitioned or not. It's not efficient.

Get a firewire 800 hard drive and record to that. I would get rid of the partition and install everything on the system drive, especially if you have 1TB.

I'm not sure i understand as i have never had this problem before ..

 

especially the one where logic has to wait several seconds before starting playback, this is not consistent though...

 

so do you mean i should have the files that are being played back on one drive and then record to another??? this seems a little strange..

 

or do you mean that the projects/arrangements should be on another drive than the system drive????

You should have Logic on one drive, and do recording to or stream samples from another.

You can compare your harddrive to a record player with one head that reads and writes. The more stuff you are demanding it to do simultaneously, the more the head has to jump around all over the place, slowing down all the processes. Partitioning a drive doesn't change the fact that it's still only one read/write head doing the work.

How about 2 external fw800 hd's ?

Internal for os/logic+audio content etc

1 for komplete 7,omnisphere,lass etc

1 for project/audio

 

any serious benifits ? I'm asking because from what I understand

the firewire 800 has a maximum transfer data rate of 80mbps

 

not nearly as fast as Sata 300mbps

I'm also interested in this .. would it make sense to have an extra FW800 daisy chained for sample libraries or is it just as good running it from the same HD as your projects???
