I have an early 2011 Macbook Pro with a Toshiba MK7559GSXP 750GB 5400rpm hard drive (that has about 48GB free) and running El Capitan. Recently I had the feeling that things were running slowly (and I probably have been ignoring it up until now), so I downloaded and ran Blacmagicdesign's Disk Speed Test 2.2.2
This speed test gave me a read and write speed of about 50 MB/s which my gut feeling is saying is not very good.
I also ran the Disk Utility's First Aid and the drive passed all the tests applied by that utility. So:
- Is this an unreasonable read/write speed?
- Would it be due to the hard drive being less than 10% full?
- Something else that I am missing?
After the storm
I just replaced the hard drive with a Samsung 850 EVO 1TB SSD. The boot time halved, Apps open almost immediately, the Disk Speed Test pegs at 480 MB/s and the Negotiated link speed is 6 GB/s.
Thats all good, but the weirdest things is how quiet it sounds now!
