Frequently Asked Questions
This resource is crafted to help you find information easily and efficiently.
What is the difference between M.2 2242 and M.2 2280 SSDs?
The numbers refer to the physical dimensions - 2242 means 22mm wide × 42mm long, while 2280 is 22mm wide × 80mm long. The ON900B's compact 2242 form factor is ideal for space-constrained devices like ultrabooks, tablets, and mini PCs. Most M.2 2280 slots can accommodate 2242 drives using the mounting screw at the 42mm position.
Will this SSD work in my laptop/device?
The ON900B is compatible with any device that has an M.2 slot supporting:
- NVMe protocol (PCIe interface)
- 2242 form factor (or larger slots like 2260/2280 with adjustable mounting)
- PCIe Gen 3.0 or newer
Common compatible devices include modern laptops, mini PCs, tablets, and some gaming consoles. Check your device specifications to confirm M.2 NVMe support.
Do I need a heatsink for this SSD?
The ON900B features a low-profile graphene aluminum heat spreader for thermal management. For most laptop and standard desktop use, additional cooling is not required. However, if you're running sustained heavy workloads or your device has limited airflow, an additional heatsink may help maintain optimal performance.
What speeds can I expect in real-world use?
The ON900B delivers up to 2,100MB/s read and 1,800MB/s write speeds under optimal conditions. Actual performance depends on:
- Your system's PCIe generation (PCIe 3.0 x4 required for maximum speed)
- Available PCIe lanes
- System configuration and workload
- Drive capacity (larger capacities typically perform better)
You'll notice significantly faster boot times, application loading, and file transfers compared to SATA SSDs.
How long will this SSD last?
The ON900B comes with a 3-year warranty and industry-leading endurance ratings:
- 256GB: 142 TBW (Terabytes Written)
- 512GB: 284 TBW
- 1TB: 568 TBW
- 2TB: 650 TBW
For typical consumer use (20-40GB written per day), even the 256GB model would last 10+ years before reaching its TBW limit.
Is this SSD compatible with PCIe 4.0 or 5.0 systems?
Yes! The ON900B is backward and forward compatible. It will work in PCIe 4.0 and 5.0 slots, operating at PCIe 3.0 speeds. While you won't get PCIe 4.0/5.0 speeds, the drive will function perfectly and still deliver excellent performance for most applications.
