Hello,

 

I have an iMac24 old version and would like to upgrade the internal hard drive to a new 1 tera model, the question is which one ? There seems to be no example yet at http://forums.xlr8yourmac.com/drivedb/search.drivedb.lasso

 

Has anyone tried it already ? I'm mostly concerned about that it works first but also on the noise of the hard drive.

 

One possibility would be to use the same as the new iMac24 which have an option for 1 terabyte hard drive, does anyone knows what is the make and model of this drive ?

 

Thanks a lot,

Well it's not that simple because:

 

1) On xl8r database for example one user, Barracuda 7200.10 750 Gb SATA wouldn't wake up because spin times were too long and/or power requirements were too high

 

2) Setting aside direct boot compatibility problems there are three 1 téra SATA drives available in my area:

- Western Digital Caviar GP WD10EACS

- Hitachi Desktar 7K1000 HDS721010KLA330

- Seagate ST31000340AS

 

which one will be the quietest (my iMac is always on next to my bed), or use the less power / go less hot (because iMac desktop is somewhat of notebook design ?). One relatively safe choice would be to take the same model as the 1 téra option of the new iMac 24, if someone could share this information.

 

3) For the difficulty, I understand that iMac 24 (old model) is easier than iMac 20 because you don't have to remove the shielding. I was mad enough a few years ago to do some soldering on a newly bought Toshiba Libretto to overclock it, so I guess I'll give it a try anyway.

The Western Digital is both the quietest and the coolest of the three.

 

Power (read/write - less power is less heat):

Western Digital: 7.4w

Hitachi: 13.6w

Seagate: 12w

 

Noise (idle, since you were worried about it when trying to sleep)

Western Digital: 24 dBA

Hitachi: 29 dBA

Seagage: 29 dBA

 

 

Data Sheets:

Western Digital

Hitachi

Seagate

They're called 'torx' and pretty much any decent hardware or electronics supplier should have them. They seem quite popular as 'security' screws despite the fact that drivers are easy to obtain. I have a fold out tool with sizes from T5-T20 on it, which covers just about anything.

Thanks, I bought the T5 to T30 kit, I guess the bottom screws were T8. Now I'm stuck on the following step, I think that to remove the LCD screen I have 4 TORX screws on each side to unscrew, unfortunately they are too deep to use my T5 to T30 kit because the mounting head mechanism is too large to reach them.

 

Guess have to buy T8 (?) screwdriver to be able to remove them. Hope that will be the final hurdle.

Torx screws are not "security" screws. They are used because they resist cam-out better than phillips screws. This makes it easier for machines to always torque the screws properly, and prevents damage to the screws and driver bit.

It's funny you say that, since I've shredded far more Torx than decent posi-drive Philips screws, and I don't use crappy tools, so I assumed they were just a somewhat poor security device...
