iFixit wrote a good post “Mac Mini Late 2012 Hard Drive Replacement” with many photos. It helps me to replace the existing hard drive in Mac mini (Late 2012). I would like to contribute two more tips which would accelerate the process.
According to fzabkar in Seagate: Forums: 2TB ST2000DM001 Barracuda from Seagate seriously cripled through redesign in 3/2012 or 4/2012, the S/N (serial number) on the label of your Seagate Desktop HDD ST2000DM001 contains information about the number of plates.
It is difficult to choose the right hard drive case for me. Therefore, I create a framework to help me compare them. It is FIPS: Fan, Interface, Power, and Solid.
In the next few months, I am going to port ZurmoCRM onto QNAP. I might need to test different configuration and need to reinstall QTS several times. Remove the hard disk and use SATA to USB bridge to kill partition takes too much time. Instead, you may SSH to login, then clean QTS partition with dd. or remove with fdisk.
Buffalo HD-LX2TU3 is my first secured external HDD box. Because I am not comfortable with the high operation temperature and the small power adapter, I decide to open the case, move the hard drive to QNAP TS-112, and use the SATA to USB 3.0 bridge as a quick connector.
I use the bridge to clone the hard drive in my Lenovo C440 AIO to a new SSHD. When I swap them, it never boot up.
When I was looking for a new hard disk for my Network-attached storage (aka NAS), I found the startup current of Seagate ST2000DM001 (aka Barracuda or Desktop HDD) in my Buffalo HD-LX2TU3 is 2.5A and output current of the adapter is 1.5A. It requires 67% higher than the adapter could offer. Is it safe use of electricity usage and okay to my hard disk?
I didn’t know and decide to research.
There are complaining about the small SSD in SSHD. But what is the right size for the SSD cache? It’s actually up to your physical RAM and operating system.
Let’s start from the basic: what is buffer and cache
