Random IO

Random read/write performance matters if you copy a lot of small files or use the drive as storage for games and applications that are directly started off the drive.

Sequential IO

Sequential performance is relevant when you copy large files—videos, for example.

Sustained Write Speeds

Sequential write speeds start out high at around 800 MB/s. At the 90 GB mark, temperature becomes an issue without the heatsink, and it first throttles down to 600 MB/s for roughly 30 GB before dropping down into the 400 MB/s range for the remainder of the test, resulting in an average of 475 MB/s.


With the attached 11 g heatsink, the Teamgroup MP34 drive cranks through the entire test without breaking a sweat, sustaining full performance with an average of 792 MB/s. This shows that the included black aluminium heatsink is truly valuable; a heatsink is absolutely something you should look for when buying an enclosure like this.
