SK hynix PC711 512GB NVMe Drive

The SK hynix PC711 is a 512GB internal solid-state drive built for laptops and desktops with an M.2 2280 slot. It uses the NVMe protocol over a PCI-Express 3.0 x4 interface to deliver faster boot and load times than legacy storage. The drive includes Pyrite encryption for basic data protection.

PCIe 3.0 x4 Interface Limits

The PCI-Express 3.0 x4 link caps theoretical throughput at roughly 4 GBps, so real-world sequential speeds cannot exceed that ceiling. The PC711 reaches up to 3300 MBps read and 2200 MBps write, operating near the boundary of the bus. Thermal throttling may occur sooner because the drive ships without a heatsink.

512GB Capacity and Headroom

Five hundred twelve gigabytes holds an operating system, core applications and a moderate game or media library with room to spare. Heavy video editing suites or large game collections will fill the drive quickly, requiring offload to secondary storage. Sustained write workloads can push the controller into thermal limits once the SLC cache is exhausted.

Questions about this item

Will this 2280-length drive fit in a laptop that only has a shorter M.2 slot?

No, the 2280 form factor is 80 mm long and requires a matching slot.

Does the drive include a heatsink, or will I need to add one for sustained loads?

It ships without a heatsink; the motherboard may provide one, but none is bundled.

My motherboard only supports PCIe 3.0 — will this SSD run at its rated 3300 MB/s read and 2200 MB/s write?

Yes, the interface is PCIe 3.0 x4, so the published speeds are achievable on a 3.0 platform.
