3/28/2023 0 Comments Xbench ssdI haven’t been able to spend much time at my Mac this week, but I am blown away at how quickly the Finder can open a window and display its contents when you’re using an SSD vs. Crucial SSDs are reported to be compatible across the board. You especially want to avoid SSDs that use Sandforce SF-2281 controllers. If your System Profiler says link speed is 3 Gigabit but the negotiated link speed is 1.5 Gigabit, unless you’re using a SATA Rev. Here’s the info from my Mac mini, which has an Intel ICH7-M SATA Rev. To see which SATA controller your Mac has, open the Apple menu, select About This Mac, and click on More Info… Next click on Serial-ATA, and it will tell you what controller your Mac uses and which SATA drives are installed. 2 speed rather than dropping to half that speed. If you have a Mac with this controller, be sure you buy a drive that will provide full SATA Rev. 1 speed with certain drives – including some SSDs. 2 controller that falls back to 1.5 MB/s SATA Rev. If you have a Mac built between 20, you need to be aware of problems with the Nvidia MCP79 SATA controller. That’s over twice as fast as the hard drive. It found 54 occurrences in 44 files – and it did so in just under one minute. A Real World TestĪlthough Low End Mac moved to WordPress for new content in early 2013, I have thousands of text and HTML files on my hard drive that were Low End Mac until the transition began – and most of them will remain that way, as they are not worth the time to convert to WordPress.Īnyhow, I used TextWrangler 4.5.5 to search each and every one of those files for a specific text string. And on random tests, the SSD has at least 6x the performance of the hard drive. Here are the specific drive test results:Įxcept for the uncached 4K sequential writes, the Samsung 850 EVO more than doubled speed in every benchmark compared to the WD Scorpio Black, which was a top-end 2.5″ hard drive in 2008. That makes the SSD 2.15x as fast as the hard drive. The Scorpio Black tested in the MacBook Pro topped out at 58.94 MB/s. 1 bus to connect its hard drive, as does the Mac mini, so although we’re comparing different machines, they both have the same maximum SATA data throughput. The MacBook Pro uses a 1.5 GB/s SATA Rev. I don’t have benchmark results for the hard drives, but I’ve found some Xbench results online using a MacBook Pro (specific model unknown but an Early 2008 one at the newest). I’ve had my Mid 2007 Mac mini for several years, upgrading RAM from 1 GB to 3 GB and the hard drive from a pedestrian 5400 rpm 80 GB to a 7200 rpm 320 GB WD Scorpio Black – and now to a 250 GB Samsung 850 EVO SSD.
