WD Blue SN580 1TB internal SSD

The WD Blue SN580 is a 1TB M.2 2280 drive that connects through a PCIe 4.0 x4 interface using the NVMe 1.4 protocol. It is built for consumer workloads such as everyday computing, content creation and large media libraries. TLC memory provides a balance of cost and endurance for these tasks.

Sustained write behaviour with nCache 4.0

Western Digital's nCache 4.0 technology uses a portion of the TLC array as a high-speed buffer to absorb incoming write bursts. During long transfers the drive maintains performance by folding data from the buffer into the main TLC area without a sharp drop in throughput. The 600TB TBW rating reflects the total data that can be written over the drive's lifetime.

Low power draw and thermal limits

Active power consumption is rated at 65mW while idle sleep power drops to 3.3mW, helping extend battery life in laptops. The controller operates within a 0°C to 85°C range without active cooling. No fan or heatsink is required for typical desktop or notebook installations.

Questions about this item

Does the WD Blue SN580 run hot or draw much power when it stays active all day?

Active power is 65mW and idle sleep power is 3.3mW, so heat output and battery impact stay very low during extended use.

What slot and keying does my motherboard need for this M.2 2280 drive?

It requires an M.2 2280 slot wired for PCI-Express 4.0 x4 with NVMe 1.4 support.

Will this PCIe 4.0 SSD work in my older PCIe 3.0 M.2 slot?

Yes, it is backward compatible and will operate at PCIe 3.0 x4 speeds in a 3.0 slot.
