Most appropriate SSD for iMac 8,1 (2008 24" 3GHz)
Posted by: mikebw
Date: October 19, 2016 03:07PM
I'm starting to look into this as a solution for extending the life of my Mom's 2008 24" 3.06GHz iMac. Would the OWC Electra 3G lineup make the most sense for that iMac? [eshop.macsales.com]

EDIT: Already running 4GB RAM, going to 6GB doesn't seem worth it for $90+.

I'd just put in either a Crucial or Sandisk, which either is cheaper. Nothing against the OWC (it's great drive) but overpriced.

Was this a replacement for the stock HD or did you put it in the optical bay?

My guess is that iMac has the nVidia SATA ll chip that limits negotiated link speed to 1.5 Gigabit when used with a SATA lll drive.
If so, the OWC 3G will link at 3 Gigabit, the others will link at 1.5 Gigabit.

OWCs neptune drives are fine, and well priced. Crucial and sandisk are also great/

Know that you may need to install SMC fan control.

Scouts honor, running it via USB 2 is snappier, and all you need is a $10 case.

Sorry, meant to say USB 2 SSD is snappier than the internal platter drive.

My 2007 iMac with an internal SSD needs the fan control. Maybe I didnt put the sensor in the right place...?

SMC fan control not necessary. Thermal sensor reattaches to SSD just fine.

what is the TRIM situation these days?

OWC claims their drives do not need TRIM, and I believe them. I never tried an OWC drive, but I do have Crucial (M4, M200) and Samsung (850 PRO!), all with 10.9.5 and I found out that speed goes down after a while, and if I enable TRIM, speed comes back up. The drives are 1/2 full BTW, so don't give me crap about drives being 99% full.

I now enable TRIM on all SSD I install in OS X.

Trim is overhyped.

have you tested the speed of a SSD with and without it, after being in use for about a year?

Yes to the OWC question. Alternative is a Crucial 500GB SSD ( or Samsung, but I don't buy Samsung products because Samsung cheats).

I have a 2007 24" 2.8GHz iMac. I added 2GB RAM and the Crucial SSD and now it is running El Cap very nicely. I used the suction cups on car phone holders actually used the whole units) to remove the iMac glass screen. That was the easiest part of the job. There are 2 zillion screws that need to be removed, so make sure you have plenty of room to lay them out in the proper pattern as you remove them. The job is not at all difficult.

Help me understand- if I use an SATA III SSD drive it will only run @ 1.5 Gbps, but if I use an OWC 3G SSD then it will run @ 3 Gbps? Is that a limitation of the SATA III SSD?

Seems like it would be easier to setup an external boot drive then? I know she already has an external for TM backups (firewire) and another drive on USB for her iPhoto library. I should do some speed tests on those to see which is the slowest and go form there.
