compatible upgrade hard drive for imac/

Posted on 2013-05-22
Last Modified: 2013-05-22
The hard drive in my 24" Aluminium Imac (early 2008) , 2.8Ghz has gone kaput, - it was a 500gb, and am looking to replace it with a 1 TB drive.

I'm ok with taking apart and re-assembling, (this will be the second drive replacement), but I have no idea what to look for regarding make and model of the proposed replacement.  

I'm in London for a few days at the moment, and have a few options.  Go into an Apple shop and pay top dollar for a replacement, which is probably the least troublesome, but most expensive.  
Can anyone recommend a drive, make, and model that will suit the bill?  
I'm aware that some drive have temperature sensors, and some don't etc.. so all advice is welcome.

Thank you in advance

Any SATA drive of the right form factor should work.

At a high level you'll need a 3.5" SATA hard drive.  The question back to you would be are there any specifics you're looking for?

Do you want speed?

Do you want quiet and energy efficient?

Do you have any brand preferences?

If you're just looking for a decent 1TB 3.5" SATA drive then there are plenty to choose from at pretty good prices.  3.5" drives are up to 4TB per drive these days so 1TB drives are pretty cheap.

Newegg has around 50 1TB SATA drives available right now ranging from $65 to around $140.

"At a high level".. Not at all sure what that means!..  In answer to your question ..."what am I looking for". Reliability, speed, low noise.   In that order.
Thank you for your help.

The form factor refers to the size of the drive and what type of computer it fits in to.

3.5 inch form factor is your standard desktop drive
2.5 inch form factor is your standard laptop drive
1.8 inch form factor is your standard size for smaller laptops

Your iMac was designed with a 3.5" drive.  

The good thing is that all SATA drives that are 3.5 or 2.5 inch have the exact same power and data connections.  It isn't uncommon for a 3.5 inch drive to be replaced with 2.5 inch drives.  Most of the time when folks do that they have to buy a 2.5 to 3.5 conversion kit so that the drive can be mounted properly.

How much are you wanting to spend on this?

They're good drives, carry a 5YR warranty and have great performance.

I personally stay away from Seagate consumer drives after too many problems with them.  Their enterprise drives are great though...

Any 3.5" SATA drive will work. I put a 2.5" SSD in my 24" iMac and made it work by using some custom brackets.

If you do want a SSD you can't use the standard 2.5" to 3.5" adapters. All 3.5" SATA drives will work though.

Took your advice and bought the Western Digital from a shop in London. They were asking £110 for it - I paid £100.  Very likely could have got it online for less, but that's the job done now.
Thanks to you all for your help and advice.
