Crucial BX500 4TB SATA 2.5-inch Internal SSD (CT4000BX500SSD1) – SATA 6Gb/s, Up to 550 MB/s, 2.5″ (7mm)

The Crucial BX500 4TB (CT4000BX500SSD1) is a 2.5″ (7mm) SATA 6Gb/s solid state drive with up to 550 MB/s read and 500 MB/s write. It is a cost-effective upgrade for laptops and desktops still running on hard drives, and a reliable drive for everyday storage.

Faster storage you notice from the first boot.

Why Replacing a Hard Drive With a SATA SSD Transforms an Old PC

Most slow PCs are held back by their storage, not their processor. Hard drives have to physically move a read head across spinning platters, so booting, opening apps and searching files take seconds instead of milliseconds.

The Crucial BX500 4TB replaces that mechanical drive with flash memory over the same SATA connection. Boot times, app launches and file searches drop dramatically, and the drive runs silently with no moving parts to wear out or break if dropped.

Drop-In Compatibility

The 2.5″ (7mm) form factor and SATA 6Gb/s interface work with older and current systems alike, so it can replace a hard drive or an older SSD without changing anything else.

Reliable Everyday Storage

Flash storage handles shocks and vibration better than hard drives, which matters most in laptops. Keep firmware updated with the manufacturer’s SSD tool for best reliability.

How to Install the Crucial BX500 4TB
