Capacity and flash type

This BIWIN internal SSD delivers 256GB of storage using MLC flash memory. The drive targets users who need reliable SATA performance in the M.2 2280 form factor. It suits upgrades for compatible laptops, small-form-factor desktops and Intel NUC units.

Build integration

The module measures 80mm by 22mm by 3.2mm and weighs 6.7g, fitting standard M.2 slots keyed for SATA. A SATA III 6Gb/s interface and onboard DDR3 cache handle data transfer without requiring PCIe lanes. Power draw sits at 0.25W idle and 2.94W active from a 3.3V supply.

Sustained operation

Sequential reads reach 561MB/s and writes reach 296MB/s under load. The controller employs BCH ECC at 66 bits per 1KB to maintain data integrity during extended writes. MTBF is rated at 2000000 hours, while the operating range spans 0°C to 70°C with 5% to 95% humidity tolerance. Shock resistance is rated at 50G for 11ms half-sine events and vibration resistance at 3.1G across 2 to 500Hz.

Questions about this item

At what point does the 561 MB/s sequential read speed stop being sustainable under a heavy workload?

The drive is rated for 0°C to 70°C operating temperature, so sustained transfers will throttle once the controller reaches that thermal ceiling.

How much heat and power does the drive produce when it runs all day at the 2.94 W active rating?

At 2.94 W active power the drive stays within the 0°C to 70°C range and has no moving parts, so acoustic noise is effectively zero.

What host hardware must already be present for this M.2 2280 SATA III drive to function?

The system needs an M.2 slot wired for SATA III 6 Gb/s signalling and a 3.3 V power rail; the drive draws 0.25 W idle and 2.94 W active.
