The Netac NV150HK comes in a pretty compact box with a clear image of the drive on the front. To the right of the image is a panel showing the drive's capacity. Above this is a line about the interface the drive uses.nertac
The top half of the rear of the box is covered in multilingual details about the interface – Gen5 x4 NVMe 2.0. At the bottom edge of the box is a panel displaying the fact that a five-year warranty backs the drive.
The drive is of a dual-sided design with Flash packages on both sides of the PCB.
One side of the PCB holds the Silicon Motion SM2508 controller, a 2GB LPDDR4-2133MHz DRAM cache IC and two packages of 232-layer NAND. The other side of the PCB is home to another two packages of NAND.
Silicon Motion's SM2508 is an 8-channel controller built on a 6nm process. It uses a Quad-core ARM Cortex-R8 processor supporting the NAND channels at speeds of up to 3,600 MT/s per channel, supporting NVMe 2.0. It supports DDR4 and LPDDR4 DRAM with transfer rates of up to 3,200Mb/s. The SM2508 supports Sequential performance speeds of up to 14,500MB/s and 14,000MB/s for read and writes, respectively. While 4K performance is quoted as up to 2.5M IOPS for read and writes. It offers best-in-class power consumption of 3.5W in active mode and less than 2mW in PS4 mode.
Netac have used a two-piece heatsink design with the NV150HK, the finned heatsink itself (weighing in at 32g), which is held in a chrome-finished cradle by four tiny screws. The drive is sandwiched between two fairly thick thermal pads.
