Crucial BX500 Spec and Price in the United Kingdom

Name: Crucial BX500
Brand: Crucial

SATA2TB2.5-inch540 MB/s read

Silicon Motion's SM2259XT controller runs the BX500 without a DRAM cache, keeping sequential speeds capped at 540/500 MB/s over SATA — Crucial's budget option at $199.99 for 2TB. Its 720TB TBW rating beats the P3 Plus's 440TB, though the three-year warranty runs two years shorter than either NVMe drive in Crucial's range.

Tied 101st of 106 models in the SSD catalog on Sequential read — 3 models share this figure. Tied 99th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.
