Hi all, I just bought my first Mac for use in my personal photo studio, a refurbed 2011 Mac Mini i5 2.5ghz. As I was setting up external drives and putting the mini through its paces, I ran a disk benchmark (BlackMagic Disk Speed Test) and got some pretty poor scores.
You can benchmark the speed of your SSD or hard disk using a few simple Terminal commands. To test write speed: time dd if=/dev/zero bs=1024k of=tstfile count=1024 In the output, you should look for something that looks like 'bytes transferred in 16.546732 secs (519131791 bytes/sec).'

My mini's internal drive hits roughly 40MB/s for both sequential read and sequential write. Am I correct in thinking that this is poor performance even for a 5400 rpm drive? The drive is mostly full; there are 50GB free. Would you recommend that I address this with Applecare?

Here are two other Minis (same 5400 rpm drive) hitting much higher marks:

Mac mini (Mid 2011), Mac OS X (10.7.2), 2.5 GHz, 8GB ram, 500GB 5400 rpm
