I have used the SANDISK SSD into my older iMAc 20вЂі 2007 Aluminium, and it work PERFECT and WITHOUT any problemвЂ¦ but into this Optibay Slot this seems to have some anomalyвЂ¦ The problemвЂ¦ the SANDISK SSD have very strange performanceвЂ¦ i am using AJA TEST SPEED (Black Magic Speed Test not start/work on my OSX, i donвЂ™t know why) and the speed are sometime good, sometime poorвЂ¦ it go from 50-60Mb/s to 180-200Mb/s for WRITE speedвЂ¦ READ speed are ALWAYS the same, about 220-240Mb/s вЂ“ Secondary SSD is SANDISK Standard 6G 256GB (i have removed the SUPERDRIVE unit and insert the SSD with the DATA DOUBLER by OWC) вЂ“ Primary SSD is CRUCIAL M550 6G 256GB (i have removed the original 3.5вЂі HDD and insert the SSD with the ADAPTA DRIVE by OWC)

In my case, the Mac mini went all the way up to OS X Mavericks, while the Macbook got OS X Lion.

Install the latest version your machine supports.

While you upgrade to an SSD, itвЂ™s worthwhile to do a clean install of OS X while youвЂ™re at it, instead of cloning your old setup.

Installation went without a hitch and the old machine is now almost like a new box. And yes, it works fine at 3Gbps, as you can see from the screenshot above. The M500вЂ™s controller is a Marvell, and there were online reports of the M500 functioning full-speed with the Nvidia MCP79 controller.

OCZ was an option since they have a firmware update to fix the SATA 3Gbps issue even on their Sandforce drives, but their reliability record is appalling, so I went with the Crucial M500, regarded as reliable. This ruled out most SSDs for this machine, including Intels, Samsungs and SanDisks. Also, one of the most popular and reliable drives, the Samsung 840, was reported as having compatibility issues as well. However, the Mac mini has the Nvidia MCP79 controller, and after extensive googling I found out I couldnвЂ™t use the Kingston or other Sandforce SSDвЂ™s, at least not at maximum speed. See for your machineвЂ™s specs.В The Kingston is a top-value Sandforce drive. The Kingston SSDNow V300 I chose for the White MacBook 4,1 has the SF-2281, but since the MacBook doesnвЂ™t have the MCP79 and doesnвЂ™t support 3Gbps SATA in the first place, thereвЂ™s no issue. In short: Nvidia MCP79 + Sandforce SF-2281 = no good. SSDвЂ™s that have the Sandforce SF-2281 controller are most problematic, and the SF-2281 happens to be one of the most common ones. Here, youвЂ™ll also see the negotiated SATA link speed. You can check if you have the MCP79 by going to the upper left hand corner Apple menu, choosing About This Mac, More Info, System Report and the SATA section. Even if you canвЂ™t get 6Gbps like modern machines, youвЂ™re still much better off with 3Gbps than 1.5Gbps if you have a choice. The bad combination might give you other issues as well.

Those Macs will not work with their full 3Gbps link speed with a lot of current SSDвЂ™s, instead falling back to 1.5Gbps only. You need to be careful when choosing your brand, since many Macs built around 2007вЂ“2011 come with the buggy Nvidia MCP79 SATA controller. Just one catch: Not all SSDs will always work as fast as youвЂ™d want. It makes a big difference in daily use for fairly low cost.

This is written after the following updates: SSDs (solid-state drives) are much faster than old-school hard drives, making it possible to get a few more years of life out of an old, slow computer by upgrading it to a faster drive.
