Everything that decides whether the Crucial BX500 is the right drive: controller, DRAM, NAND, rated endurance, PS5 and laptop fit, and how it compares with the obvious alternatives. Hardware facts are taken from the reviews and datasheets listed at the bottom; capacities and speeds come from our comparison of 60 drives.
Who it’s for: Low-cost bulk SATA storage in a 2.5-inch bay, where capacity matters more than sustained speed. Skip it for: Large file transfers: Tom's Hardware measured about 85 MB/s once the SLC cache filled. Warranty is three years, shorter than most rivals.
| Controller | Silicon Motion SM2259XT (4-channel) |
| DRAM cache | No — DRAM-less |
| NAND | Micron 3D NAND (QLC at the larger capacities) |
| Interface | SATA 6 Gb/s, 2.5-inch |
| Heatsink version | Not in our data — sold bare |
| Capacity | Seq. read | Seq. write | Endurance | Warranty |

Rated endurance is 240 TBW at 960GB. We could not confirm the rating for the 4TB model from a primary source, so it is left blank. Speeds are the manufacturer’s sequential ratings.
Every Crucial BX500 capacity in our comparison, smallest first.
The Crucial BX500 is a SATA drive: it fits a 2.5-inch drive bay. It will not work in an M.2 slot that only supports NVMe, and it does not meet the PS5’s NVMe requirement. If your machine has an NVMe slot, an entry NVMe drive is many times faster for about the same price per terabyte.
How to identify your slot: cheapest SSD for a laptop · all SATA SSDs.
Samsung 870 Evo: a SATA drive with DRAM and TLC for consistent speed.
Kingston A400: another DRAM-less budget SATA drive.
We show retail prices only while we can refresh them at least every 24 hours. For market context: TrendForce’s 16 Oct 2026 retail sample runs $133–$250 per TB for mainstream 1–2TB drives, and NAND contract prices are forecast +15 to +20% for 4Q26. Check any listing against that range with the price per TB calculator, and see the SSD price chart for the trend.

Where reviews disagreed (for example on NAND layer counts or a capacity’s endurance rating) we state only what the sources agree on.
