Installing an SSD

So I decided to purchase an SSD for my Mac mini using some of the Amazon Vouchers I received for Christmas. After much research, I decided on the Samsung 840 EVO 250GB SSD from Amazon UK, which, at the time came in at £85.80. I bought a small fitting kit from eBay for £10.

I’ve uploaded a video to youtube. It is a highly sped-up version of me installing a Samsung 840 EVO 250GB SSD. I run a pretty standard 2.3 GHz Intel Core i7 Mac mini, with 16Gb RAM that I installed as soon as I purchased the machine.

You need an additional kit to fit the hard drive, which I purchased from eBay for £10. Beware however. The kit I purchased came with everything I needed, but the rubber grommets were too stiff and thick! I had to cut one grommet in half which fixed the issue.

All in, it took me about an hour to do taking my time and verifying everything I was doing with the iFixit site.

Before starting, my primary and pre-installed (1Tb) hard drive was showing as the bottom hard drive caddy in System Information.

On opening the mini, the Hard Drive was sitting at the top of the caddy, which, when the mini is sitting the right way up, would make it the bottom drive. The original SATA cable was plugged into the left port as you look at the mini being disassembled, which is the one nearest the bluetooth and Wifi antenna connector.

Eventually I put the 1Tb Hard Drive into the upper bay, transferring the black sheath around the original Hard Drive to the new SSD, and used the new SATA cable for the existing Hard Drive. I then put the new SSD in the bottom part of the caddy and used the existing SATA cable.

I swapped the cables as I read a few stories about read/write errors using third party SATA cables in the mini that only affected SSD drives. Better being safe than sorry!

I have a full video of my installation, including the issue with the grommets.

Before starting, I took a quick video to see how long it took to boot. My start was switching the mini on. The Stop mark was when the TomTom update helper popped up letting me know I had updates flashed onto the screen. I was a few milliseconds slow in stopping the video after the SSD install, but even with the time given, its still an astonishing difference.

Mac mini with no SSD boot time: 3 minutes, 15 Seconds.

Mac mini with SSD boot time: 56 Seconds.

I reckon thats near to a 72% speed increase in the boot time alone.

Generally I keep the mini running 24/7, so boot up times are not all that important, but the difference in software starting is astounding. iPhoto loads lightning fast, as does pixelmator. iMovie also. Other apps don’t even blink!

I’ll give it a few months and measure the performance again to see if it can keep it up.
