Synology SNV3400-400G 400GB SSD Review

Synology's SNV3400-400G comes in a compact box, free of any images of the drive, not surprising as the drive is labelled as an enterprise drive. On the right-hand side of the box front is a panel with three bullet points about the drive; Consistent performance, validated compatibility and minimum service disruption.

On the left-hand side under the product name is a line informing that the drive is for Synology servers. At the bottom of the box is a band displaying the drives capacity and the fact it's one of the SNV3400 series. The back of the box displays warranty information and repeats the capacity and product family information.

The SNV3400-400G is built on a dual-sided M.2 2280 format. One side of the PCB houses the Phison PS5012-E12DC controller, two 128GB packages of Kioxia BiCS3 64-layer TLC NAND (coded TA7AG55A IV) and a single 4GB DDR4 (SK Hynix H5AN4G8NBJR) cache IC. The other side of the PCB just houses two more NAND packages.

The DC is the enterprise optimised version of Phison's 2nd generation PS5012-E12 8-channel PCIe NVMe SSD controller. Built on a 28mn process the controller supports Phison's 3rd generation LPDC EEC correction engine, AES 256 bit hardware-based encryption and end to end data protection.
