Ssd pour mac mini 2009

Upgradeable

At least stay away from Sandforce driven SSDs. The trick with leaving the drive plugged into power-only for some hours is weird but works obviously! The "problem" is Macs last too long.

Make sure your systems firmware is upto date as Apple did address some SATA port issues within the newer firmware level. See if that works some of the newer versions of this system will work with the newer auto sense SSD's. Thanks but the firmware is up to date.

The original Apple drive also runs at 1. I don't count a 6Gb drive running as 3Gb as a failure.

Get everything you need to upgrade your Mac mini SSD for a total system performance and capacity boost. All SSDs are backed by a lifetime warranty. I want to upgrade my mac mini late with a SSD since my HD is beginning having problems booting. I know that my mac mini has got a.

Even if all newer drives are 6Gb they should autosense down to 3Gb. This is a bit confusing: Some newer drives have auto sense which allows them to match to the systems SATA ports speed. SATA III drives when they first came out also had this compatibility jumper, as the need for running in the older systems lessened the jumper was pulled.

Sadly, not all systems can support the auto sense drives like this one. No Dan, this is not confusing. If you read this post: From my experience I have used almost any 6Gb current drive on any old MacBook system. All current 6 Gb drives you can hardly find a 3Gb anymore are autosensing. Seems there is something special going on with the Nvidia MCP79 Mac Mini not communicating with the drives controller specially the Sandforce but also Samsung.

The drive jumps back to its lowest possible speed which is 1. I have not seen jumpers on 2. Correct the Nvidia controller has a problem running Auto sense drives. That was the point. And yes SSD drives don't have jumpers any more as they are auto sense. Different SSD manufactures do auto sense differently.

Some like the MacBook Pro's won't allow the better auto sense drive link up as their clocks are slightly off. So this is where the older fixed drives are needed and harder to find now.

As to the Apple drive: To my surprise, I found the link operating at 3 Gbps. I had no illusions that the failed firmware loader had miraculously updated the firmware, but I found it curious that the link would be at 3 Gbps after trying to boot from the CD.

I ejected the CD and restarted the Mini, only to find it back at 1. Even after several restarts it stayed at 3 Gbps, as long as the CD was in the drive. I can now repeatably and reliably get the link to run at 1. Based on my observables, I would isolate the finickyness of the NVidia MCP79 chipset to a timing issue at boot—if you allow the startup to occur normally, the link negotiation will fall back to 1.

If you instead interfere with the startup, say by having a CD in the drive or by running Startup Manager, the link will negotiate to 3 Gbps. I'd be curious to hear how other SSDs fare with this solution; I'd also be interested in whether the CD solution works on an internal Superdrive.

Thanks diablote for a really great post! You did some good investigations here. The buggy NVidia SATA chipset has a negotiating problem and your testing shows that is is a timing problem on startup. The chipset does not really care if the drive is 6 Gbps or 3 Gbps but is saying " can I negotiate with you - can you do 3 Gbps? The Sandisk firmware is forcing the drive from 6 Gbps to 3 Gbps which maybe the chipset understands then faster.

Warranty & Support

I wonder if you tried my approach with leaving the SSD on power-only for some hours? Since the last upgrade to OS X I have not upgraded to OS X I came across your USB power-only post and was about to try it when I found the Sandisk firmware addressing the issue leading to the workaround I described. Given the trouble of opening the dang Mini and how seldom I restart it it's an always-on file server , I probably won't get around to it soon. Sure let us know if you test the RAID 0 setup. I fear newer SSD drives will be even more incompatible in the future to downgrade to 3 Gbps but then again how long will a Mac Mini last?

Seems these macs last forever.

Wow, that is a fast mac, really. The link speed issue persisted and still persists , and the power-only mode you recommended did not fix it. Further testing showed that the link speed is actually just random, and no interaction at startup influences the outcome. Out of 43 startups 21 restarts, 11 startups from off, and 10 startups from off with Startup Manager , I got 25 at 1. The highest number of startups at the same link speed was 4, and the minimum was 1. Interestingly, the second SATA channel always came up at 3 Gbps, though the speed of the volume went as the link speed of the first channel.

Hi diablote, did you try the trick with an external CD to delay the startup? Would be interesting to see if a delayed negotiation would help. Does not impact the installation, as two screws is more than adequate for secure installation. Very nice piece of equipment. Comes with decent instructions. I could probably stand on this thing! Installation was very straightforward. Tools are provided which is a plus. Perfect fit! Well made, worked perfectly to replace the optical drive with an SSD breathing new life into my late Mac Mini.

Sadly, the logic board has an issue which you can't over come with the SSD you are using. However, if you are a high graphic user - playing games, or editing videos and photos you will need between 16G and 20GB.
