The cited Samsung drive fields and ASUS motherboard slot fields match on M.2 2280 and NVMe. Confirm the exact slot, CPU and physical clearance before use.
What the two maker specifications say
MZ-V9S4T0BW is listed by Samsung as 4TB with NVMe, PCIe 4.0 x4 and M.2 2280 dimensions. The EX-B660M-V5 D4 technical page identifies the following slots with the same documented protocol and length.
| Board slot | Protocol | Supported lengths | Board PCIe entry | Other conditions |
|---|---|---|---|---|
| M2_1 | NVMe | 2242, 2260, 2280 | 4.0 x4 | Check current board manual |
| M2_2 | NVMe | 2242, 2260, 2280 | 4.0 x4 | Check current board manual |
Specification match; confirm the actual build
These independent product specifications support a possible physical and interface fit. Neither manufacturer source establishes that PCCompat installed and booted this exact combination. The board CPU, BIOS, lane-sharing and heatsink conditions can still affect the result.
Before installing the drive
- Read the board label and confirm the selected M2_1 or M2_2 slot in the current manual.
- Check MZ-V9S4T0BW on the drive packaging; a similar capacity or heatsink suffix can change dimensions.
- Check the selected CPU family and occupied PCIe/SATA resources against the board storage table.
- Check standoff placement and any motherboard M.2 cover against the drive thickness and heatsink.
- Confirm firmware detection and boot settings using the board maker’s instructions.
Evidence boundary
This is a manufacturer specification comparison at the referenced check dates. It is not an exact drive QVL entry, hands-on test, guaranteed negotiated speed or promise that a system can boot from this slot. Use the linked current official pages as the final authority.
