Capacity and fit

The Crucial BX500 is a 4TB SATA solid-state drive in a 2.5-inch form factor designed for consumer laptops and desktops. It uses 3D NAND flash and a host memory buffer instead of a dedicated DRAM cache to deliver up to 540MB/s sequential throughput.

Thermals noise and power

With no moving parts the drive runs silently and generates minimal heat during typical workloads. It is rated as 45 times more energy efficient than a typical hard drive, which helps extend battery life in portable systems.

Upgrade path

The BX500 replaces a mechanical hard drive and offers up to 300 percent faster performance for boot, application load and file transfer. The jump is worthwhile when you need large capacity on a SATA interface without the cost of a DRAM-equipped SSD.

Questions about this item

How do I install the 2.5" SATA drive in a laptop, and which step is often missed?

Mount the drive in the 2.5" bay, connect the SATA data and power cables, then initialise the 4TB volume in the operating system before use.

What maintenance or replacement will the 3D NAND SSD need over time?

No mechanical service is required; enable the operating system trim command and monitor the SMART health attributes using Crucial Storage Executive.

What limit appears first when writing continuously to the 4TB BX500?

The DRAM-less design relies on host memory buffer, so sustained write speed drops once the SLC cache fills and the drive writes directly to 3D NAND.
