Mac mini 2009 ssd benchmark

See this tutorial.

2. Check your Startup Items

The copying rate was roughly 40GB per hour, which is fairly slow, but not unexpected. Because I was using my computer during the clone, I know I missed some changed data. After the first clone was completed, I quit all active programs and shut down several services, and did another pass. This one took only about 40 minutes to complete.


I renamed the startup volume to a different name, and renamed the external SSD exactly as the startup disk was originally named. Everything else worked without any fuss. The FireWire bus is clearly fast enough to make the difference for the kind of reading and writing that was occurring. Restarting the first time, in which OS X was clearly engaged in some cleanup and caching, took about six minutes.

Subsequent restarts are in the two- to three-minute range.

2012 Mac Mini and SSD poor performance

The maximum tops out at just above 11GB, when it used to approach 15GB or more. This is inexplicable and counter-intuitive. Why would faster storage result in more unused RAM? 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.

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. Show 13 more comments. In "early " SanDisk works sometimes 3Gbit, sometimes it goes to 1,5Gbit.

I cannot understand what affect at behavior like that. At this time no solution for this Mac. In "late " I had the same problem. Then I noticed a small switch in my Optibay.

So this solves the problem. Sadly, the logic board has an issue which you can't over come with the SSD you are using. The sensory logic can't reliably tell what the systems SATA port speed is so it jumps down to the slower speed to make sure it will work your SanDisk zs GB drive. OK what to do? If you can't get the zs to work you'll need to get different drives or accept the fact you'll only get SATA I performance in this series of Mac Mini. SanDisk zs specs. Mac mini 2. Is it correct?

Having a Porsche is greate if you can drive it on the Autobahn, doesn't help you drive in downtown Munich :- Basically, the limits of the system remove most of the gains from a better performing SSD. Focus on what your needs are in the SSD's size and if it can be set to SATA II so it works correctly in your system with the carrier you have or get one that resolves the problem like this one in the link.

Voila, it seems that these sucsessfull tested in above, the crucial bx and the sandisk Plus, they almost have the same Controller! As an other result i learned that my fine working lowend sandisk ssd could be replaced by a faster sandisk Plus. I look forward :-D. In my case mbp mid 09 after the sandisks i was testing a samsung evo gb MZE since june and it went fine under El Capitan.

Now i've upgraded to a gb evo in december, works also fine, 3Gbit, trim enabled. Brom brom It runs at 3. I'm running El capitan. So don't stuff it and allow it Some idle time at the end of the day. It works for me.

  • On a Mac, press the Options key while powering on to enter the Startup Manager screen. Interesting if it works. Have to try that. So "some idle time" is 1 minute? Will post back if it works! I have almost given up getting this to work stable. Wichtig sind nicht die Marketingangaben der max.

    Transferraten SATA1 schafft max. Wenn man es selbst macht, lohnt es sich immer. Wer sich einen neuen Mac ohne SSD holt, der ist selbst schuld. Insbesondere beim IMac sehe ich das als Mindestausstattung. Hier ist die Nachruestung auch ein bisschen aufwendiger und fordert zwei geschickte Haende. SSD ist ein Muss bei neuen Macs! Damit das funktioniert habe ich von SilverStone einen entsprechenden 2,5" auf 3,5" Adapter verwendet, damit der Einschubrahmen wieder passt.
