They’re designed to handle all those small transactions quickly and efficiently. System memory or RAM uses the same type of flash components as today’s Solid State Drives. This is why more memory added to the system makes the whole computer work better, multi-task more efficiently and ultimately feel faster. The platter-based 5400RPM stock drive gives an almost abysmal 14-16MB per second transfer rate. This can actually be quantified by examining the 4kB-1MB random read/write speeds of each setup.

The more memory and the faster the hard drive, the more “zip” your computer has overall or the quicker using your computer “feels.” Average Random Read/Write Transfer Rates of 4kB-1MB files in a 2011 Mac mini. But when you’re out of RAM space, or for files such as cookies and caches, the hard drive is where that data is stored. Most, but not all, of these small data transactions are between the OS and the RAM installed in your computer. Keep in mind the above chart shows only the averages including large data transfers such as the files you’re working with versus the small data reads and writes that the OS routinely makes. I don’t deal with data larger than my pictures and music.

Then we tested two OWC Mercury EXTREME 6G SSD in a RAID 0 configuration (on the server model of Mac mini – again we’re looking into how to get a second hard drive into the consumer model, but that will be another blog post down the road after we figure it all out) we got Thunderbolt-saturating speeds averaging 995MB/s and 994MB/s for read and write speeds respectively. The speeds are well over twice as fast boasting 506MB/s read speeds and 432MB/s write speeds from a single drive! Pretty good for speeding up a lot of data intensive activities like importing music and video.īut if you’re into audio editing, video editing, or doing anything else that reads and writes large amounts (or several small amounts) of data – there’s just no substitute for a SATA Revision 3.0 capable SSD such as the OWC Mercury EXTREME 6G SSD. Now, Apple does offer their own 256GB SSD option (a $600 add-on which isn’t available on the 2.3GHz base model) which boosts the average speed to an impressive 210MB/s read and 182MB/s write.
Plenty of speed for your average email / web-surfing / social media computer. With the factory stock 5400RPM hard drive, which is what most people are used to computing with, the Mac mini goes pretty fast achieving read/write speeds around 86MB/s – consistently above the maximum rated 80MB/s of an external FireWire 800 connection. The chart above shows the average read/write speeds as reported by QuickBench in four increasingly beneficial drive configurations in our 2.5GHz Intel Core i5 Mac mini (RAID 0 configuration results obtained from a 2.0GHz Intel Core i7 Mac mini Server as that is the only machine that comes factory stock with two available drive ports.) So, how fast are they?
In our excitement on discovering the functionality of the drives, we posted screenshots of a few of our test results, but we wanted to put what that means for you into perspective. We teased a bit with our post from last Friday exclaiming that the OWC 6G SSDs work with the new 2011 Mac mini.
Our benchmarking has been completed on the latest round of Mac mini machines from Apple.
