iMac 2008 replacement hard drive dilemma!

I'm having trouble choosing a replacement hard drive for my early 2008 iMac 3.06ghz w/4gb RAM. The original 500gb 7200rpm drive died after 18 months of light use.

My authorized Apple service provider wants to replace it with a new WD Caviar Green 1TB 64mb cache that only runs at 5400rpm, and they strongly recommends against upgrading to a Caviar Black 7200rpm since they tend to run hot even in less restrictive desktops and enclosures.

I do quite a bit of photo editing and don't want to suffer a major performance hit in latency and access times by "downgrading" to the Caviar Green. But other than spending big bucks on an SSD, I don't know if I have any other options with another brand.

So I'd greatly appreciate any tips or thoughts on my dilemma. Has anyone upgraded their 2007-2009 aluminum iMacs to a new hard drive and what was your experience? Should I play it safe with the Caviar Green, or roll the dice with a Caviar Black, accepting the fact that I might suffer an early hard drive death?

Thanks in advance for your help! 🙂

Hi ChiMac71

Welcome to Apple Support Communities

I put a WD Caviar Blue in my 2006 Intel iMac a year and a half ago and have not had a single problem or complaint. > http://www.wdc.com/en/products/index.asp?cat=3

A few folks here have reported issues with the Green's being slow to respond after a period of inactivity. Check the spec's, I don't really believe that under normal usage the Black would run all that much hotter, but if you are concerned go for the Blue.

There are some great deals out there for the WD 1T Caviar Blue's.

I have had the same problem with my 20inch 2.4 320Gb HDD which I bought new in Nov 2006. Last Sunday the HDD died (the 2nd HDD in less than 2 years).

I have been looking and the WD Caviar Green SATA Hard Drive 640 GB, SATA 3 Gb/s, 64 MB Cache and have been wondering if this will be ok. It does say on their site the following: "...WD GreenPower Technology yields lower operating temperatures for increased reliability..." ( http://www.wdc.com/en/products/products.asp?driveid=779 )

Would this be a good option?

I think the "green"/5400 drives are a good option for these boxes, but I wanted a bit more performance so when with "SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache ":

It's been working very nicely for several months for me now in my early 2006 20" iMac. I have installed Fan Control to cool things down a bit over stock (search for my posts this year for more info).
