Cheetah Drive T-cal

Recommended Posts

I am in the process of building a new computer for my home studio.

I was initially advised not to have a drive installed that performs t-cal while the drive is in use.

The technician who has been assisting me said he researched and found that the Cheetah drive that I wanted doesn't support this feature.

He said that I would have to go with the slower 7500 rpm (18 gig) drive or with the larger (36 gig) 10k rpm drive.

While the slower drive is less expensive it does not have the speed, and the larger drive blows my budget right out of the water.

Is there anyone using the Cheetah drive? Does the thermal calibration screw with your recording?

Does anyone have any insight/advise?

Yes, thermal calibration will cause your system to "hic-up" when it re-calibrates, and if it does this during audio transfers, you migh get a click, pop...


Western Digital drives do not use T-Cal. Have not ever had any problems with them. The Western Digital Caviar series are A+.


There are other brands too.

From what I understand, thermal recalibration used to be more of an issue than it is now. Several years ago, there were special "A/V" drives that didn't do recalibration while recording. But now, most drives use the same technology, whether they're "A/V" or not.


As to speed, remember that faster drives tend to be noisier, which could be a problem. I would think that 7500 RPM would be enough for all but the most track-intensive applications. Besides, the nice thing about hard drives is you can always add another one at a later date...

Bigger and faster is always better when talking HD storage, especially when working with multi-projects on a day to day basis.

If you can get the extra money without selling a kidney you should purchase the 36gig/10k.

As always the more power and storage your system has the quicker you'll find that it is just never enough and start to want more.

At least thats the way it works in the magical land of PT operators.

Let us know when this happens to you.

I just found out from Seagate themselves that all of the drives that they have produced for the last three years use what's called "Embedded Servos".

This eliminates the need for Thermal Re-calibration.

Needeless to say, I will be going with the originally planned drive.

I thank everyone for their input.

This is off topic a little, but I'm just giddy with excitement... I just bought a Maxtor 60gb drive bringing my home recording setup to 113.5gig... Oh my! I calculated it out, and the 60gb drive alone will contain over eight hours of constant 24-tracks of 16/44.1, or 102 hours of two-track audio - Or 1024 hours of crappy 128k mp3s! :P


Interestingly, though the 60gb drive is only 5400rpm, the Echo Reporter software said it would playback 64 tracks (+-4) only a handful less than my 7200rpm drives.


What fun!!! My boss remembers paying $600 for a *used* 640mb drive for SDII just 10 years ago. He was excited to be able to store a whole albums worth of mixes on one drive...
