This laptop was connected via a Plugable 2.5GbE USB-C adapter to a TP-Link 2.5 GbE network switch, as were all of the NAS systems for benchmarking. Plex media tests were carried out with, in addition to the aforementioned iMac, an Xbox Series S and an Apple TV 4K, both hardwired to the network. The testing parameters within CrystalDiskMark were as follows:

The NAS itself represented the best box I could justify. Being four bay, it also gave me the opportunity to spread my expenses over a longer period.

Single-Level Cell (SLC): They can only store one bit per cell and take up to two levels of charge. SLC NAND offers the highest performance, reliability and endurance (up to 100K P/E (program/erase) cycles). However, the memory density is the lowest among the variants and the price per GB is considerably higher than the other types. SLC is only available in 2D format and mostly used in enterprise setups.
