Best 2.5″ SSD

Which SSD?

I am researching the purchase of an SSD for a Mac Mini (Late 2012) which I’m using as a standalone PLEX Media Server. Right now I have maxed out the memory (16GB) and it has a Barracuda SSHD as the drive. It is my hope that an SSD will not only speed up the boot process, but do a better job at transcoding for PLEX. It is my understanding (to a degree) that the constant accessing of the database and metadata for PLEX can wear SSDs down a bit quicker, so ideally I want something that is not only fast, but reliable as something that will be on nearly 24/7. I know NAS drives are designed for this, but can I use an Ironwolf NAS drive as a hard disk replacement in a normal computer? If not, between the Barracuda and the FireCuda SSD, what would be the better choice for this usage?

I’m fairly tech savvy, but you’re not kidding when you say this stuff can get complicated.

Yes, depending on a use case, SSD wears out at a different rate. In harsh environments like RAID, cache, and heavy access you need to look at endurance rating. Bigger means a longer lifespan and not a decreased performance even with a heaviest access.

Apart from that, you could look at MTBF which is life expectancy. This do not ensure good performance at its peak times, but it indicates life expectancy on a regular use case without pushing its capabilities.

And IOPS will mean how quickly this SSD can respond to a request. This is useful for web servers and similar use cases.
