SK hynix

SK hynix BC501 256GB M.2 2280 PCIe NVMe internal SSD

SKU CH-HHPJ-6AS63

256 GB PCIe NVMe M.2 2280 internal SSD with 1300 MB/s read and 860 MB/s write speeds

  • 256 GB capacity gives room for OS and apps
  • PCIe Gen3 x4 NVMe interface enables fast data transfer
  • 1,300 MB/s sequential read speeds up boot and load times
  • 860 MB/s sequential write speeds accelerate file saves
  • M.2 2280 form factor fits standard laptop and desktop slots

Capacity and interface

The SK hynix BC501 is a 256GB M.2 2280 internal SSD that connects through a PCIe Gen3 x4 NVMe interface. It suits notebook or desktop builders who need a compact, single-sided drive for a standard M.2 slot.

Sustained write behaviour

Sequential write speed peaks at 860 MB/s, a figure the controller maintains until the SLC cache is exhausted. After that point throughput drops to the native NAND rate, so large, continuous transfers will settle below the peak number.

Deciding specification

The 256GB formatted capacity is the single figure that determines whether this drive fits the workload. Buyers who need more space for operating system, applications and media should select a higher-capacity model.

商品問答

How much power does the BC501 256GB draw under sustained load?

The drive uses a PCIe Gen3 x4 NVMe interface with maximum sequential speeds of 1300 MB/s read and 860 MB/s write; typical active power for this class of controller is low enough for standard laptop cooling.

What motherboard slot is required to install the BC501?

An M.2 2280 key-M slot wired for PCIe Gen3 x4 NVMe is required; the drive will not work in shorter M.2 slots or PCIe x1/x2 wired slots.

Will the BC501 work in a system that only has PCIe Gen2 M.2 slots?

Yes, the NVMe drive is backward compatible with PCIe Gen2 slots; it will operate at Gen2 speeds instead of the rated 1300 MB/s read and 860 MB/s write.
