Western Digital My Cloud DL4100 review

The future looks cloudy for WD’s new business NAS appliance

More on the hardware

WD uses a tray-less drive loading system where you just slip them into each bay and close the locking lever behind them. The only drawback is this arrangement doesn't support SFF hard disks.

The chassis has two power inputs so redundancy can be added with a second power brick although this costs 70 ex VAT. You could use a UPS instead but the power brick uses C5/C6 clover-leaf connectors and not a standard kettle lead.

Build quality is very good and the appliance's single cooling fan is whisper quiet. The 2GB of memory is easily upgraded to 6GB by removing the cover and popping a 4GB SO-DIMM module into the spare slot on the side.

Along with dual Gigabit and a single USB 2 port, the DL4100 has two USB 3 ports with the front one accompanied by a backup button After inserting a USB storage device, we pressed the button and the appliance automatically copied its contents down to a predefined share.
