512 GB M.2 SATA SSD for everyday PCs

The Intel 545s Series SSDSCKKW512G8X1 is a 512 GB internal solid state drive built for consumer laptops and desktops. It uses 64-layer 3D NAND TLC memory and a SATA III interface to deliver up to 550 MBps sequential read and up to 500 MBps sequential write speeds. Random performance reaches up to 75000 IOPS read and up to 85000 IOPS write, with read latency of 50 µs and write latency of 60 µs. The drive draws 40 mW idle and 4.5 W active across an operating range of 0°C to +70°C.

SATA III interface limits and benefits

The SATA III link caps throughput at 6 Gbps, so the drive cannot exceed the quoted sequential figures regardless of the host controller. Random workloads are bounded by the 4 KB IOPS ratings and the 50 µs/60 µs latencies. Power consumption stays low at 40 mW idle, helping battery life in mobile systems. Endurance is backed by a 1600000 hour MTBF and a shock rating of 1500G at 0.5 msec. AES 256-bit self-encryption is supported for data security.

Simple drop-in installation for SATA M.2 slots

The M.2 2280 form factor fits standard SATA-keyed slots in most laptops and desktops. Installation requires inserting the module at an angle and securing it with a single screw; no cables or brackets are needed. Common issues arise when the slot is wired only for PCIe signalling, which this SATA drive does not support. Verify the platform documentation lists SATA M.2 support before purchase. Ensure the firmware is current and the BIOS is set to AHCI mode for best compatibility.

Questions sur cet article

Should I pick the 128GB, 256GB or 512GB version of the 545s?

The 512GB model shown here gives you the most room for OS, apps and media; the 256GB and 128GB variants use the same SATA III interface and 64-layer 3D NAND but provide less capacity.

What does the 550 MBps sequential read figure mean once the drive is installed?

It is the maximum sustained read speed the controller can deliver over SATA III; real-world boot and file-open times will be lower but still far quicker than a mechanical hard drive.

The drive uses an M.2 2280 slot — does that mean it runs on PCIe?

No, this 545s uses the SATA III protocol through the M.2 2280 connector, so it is limited to the SATA III bandwidth ceiling of 6 Gbps.
