Compact M.2 2230 NVMe Drive

The Western Digital PC SN5000S is a 512GB internal solid-state drive built for industrial use and tight spaces. It connects through a PCIe 4.0 x4 interface using the NVMe 1.4 protocol. The 2230 form factor suits thin laptops, embedded boards and small-form-factor PCs where a full-length module will not fit.

No Heatsink Thin Profile

The drive ships without a heatsink and measures 4.30mm in height, allowing it to slide into shallow M.2 slots. Its 42.8mm width and 36.4mm depth match the 2230 standard, while the 100g weight adds negligible mass. The bare PCB design means thermal performance depends on the host device airflow or chassis contact.

Endurance And Random Performance Metrics

Rated at 600TBW and 1.75M hours MTTF, the drive targets workloads with heavy write cycles. Random read reaches 800,000 IOPS and random write reaches 1,000,000 IOPS, supporting responsive multitasking. Sequential speeds hit 6,500MB/s read and 5,000MB/s write for large file transfers. ReadyBoost support lets Windows use the SSD as a cache device.

Questions about this item

Does the PCIe 4.0 x4 interface cap real-world throughput at 6500 MB/s read and 5000 MB/s write?

The PCIe 4.0 x4 link supports up to 6500 MB/s sequential read and 5000 MB/s sequential write, so the drive saturates the bus at those figures.

Will the 2230 length and 4.30 mm height fit my ultrabook slot?

The drive measures 42.8 mm long, 36.4 mm wide and 4.30 mm tall, matching the standard M.2 2230 footprint for thin laptops.

Do I just slide it in at an angle and screw it down, or is there a thermal pad step I might miss?

Insert at roughly 30 degrees, press flat and secure with the single M2 screw; no thermal pad is required because the unit ships without a heatsink.
