Capacity and audience

This 512GB internal solid-state drive uses MLC memory and a PCI-Express 3.0 x4 interface. It is intended for consumer workloads such as operating-system installs, application storage and general file access. The 26-pin connector fits standard M.2 2280 slots in laptops and desktops. No heatsink is included with the drive.

Interface and lane count

The drive operates over PCIe NVMe Gen 3.0 using two lanes, which limits peak throughput compared with four-lane designs. Sustained sequential read reaches up to 3500MBps while sustained sequential write reaches up to 2700MBps. Buyers should verify that their platform can supply an x4 electrical connection even though the controller uses only two lanes.

Thermals and power

Operating temperature range is 0°C to 70°C and storage temperature range is -40°C to 85°C. Power draw measures 0.011748W idle, 0.075623W average, 0.458W maximum during reads and 0.908W maximum during writes. Vibration tolerance is rated at 2.17G peak across 7–800Hz. The bare PCB measures 80mm by 22mm by 3.5mm.

商品問答

What does the 3500MBps read figure mean once the drive is installed?

The 3500MBps sequential read is the peak throughput the controller can sustain over the PCIe 3.0 x4 link when the system can feed it large, contiguous blocks; real-world speeds depend on workload, queue depth and thermal limits.

Which interface standard does this drive use and what does it cap in practice?

It uses a PCIe 3.0 x4 interface with NVMe; the four-lane Gen 3 connection caps theoretical bandwidth near 4GBps, so the drive's 3500/2700MBps ratings sit within that ceiling.

What physical slot and clearance does the M.2 2280 board need to fit?

The drive follows the M.2 2280 form factor — 80mm long, 22mm wide and 3.5mm thick — so it requires a standard M-key slot with at least 3.5mm of vertical clearance above the motherboard.
