Capacity and interface

The SNV3S/4000G is a 4TB internal solid-state drive built to the M.2 2280 form factor and the PCI-Express 4.0 x4 interface. It uses the NVMe protocol and a controller that supports Host Memory Buffer operation instead of a dedicated DRAM cache. The drive is aimed at consumer desktops and laptops that need a single large volume for applications, media libraries and game installs.

Sustained workload behaviour

Under continuous load the Gen 4x4 controller maintains throughput close to the rated 6000 MBps read and 5000 MBps write figures while drawing less power than earlier designs. Lower heat output keeps the drive within its 0 to 70 °C operating window without requiring active cooling. The 2000000 hour MTBF rating reflects the endurance expected from typical daily write cycles.

Deciding specification

The single figure that determines fit is the 4TB capacity delivered through a PCI-Express 4.0 x4 NVMe link. A system must provide an M.2 slot wired for four lanes of Gen 4 signalling to reach the advertised speeds. If the slot is limited to Gen 3 or two lanes the drive will still function but sequential transfers will fall well short of 6000 MBps.

Questions about this item

Does the SNV3S/4000G run hot or draw much power during all-day workloads?

The drive is designed for lower power consumption and reduced heat, operating between 0°C and 70°C without a heatsink, so it stays cool during extended use.

What motherboard slot and keying does the SNV3S/4000G require to function?

It needs an M.2 2280 slot wired for PCIe 4.0 x4 with NVMe support; the single-sided 2.30mm board fits most laptops and desktops with that keying.

Will the SNV3S/4000G slow down if I keep it alongside an older PCIe 3.0 NVMe drive?

Each drive negotiates its own link speed, so this SSD will run at PCIe 4.0 x4 while the older drive stays at PCIe 3.0 x4 without mutual throttling.
