1. Crucial BX500 vs MX500: Form Factor and Interface
In solid-state drive, form factor decides and prescribes the size, shape and other physical specifications of a drive. The hard disk interface is the connection part between the hard disk and the host system. It is used to transfer data between hard disk cache and the host memory. Different hard disk interfaces determine the connection speed between hard disk and computer.
So, as for BX500 vs MX500, there are some differences among form factors and interface.
The Crucial BX500 comes with 2.5-inch form factor and SATA 6.0 Gb/s interface. While the Crucial MX500 SSD is available in m.2 and 2.5-inch form factors, with the SATA 6.0 Gb/s interface.
2. Crucial BX500 vs MX500: Capacity
When choosing a hard drive or a solid-state drive, hard drive capacity is a necessary factor to be considered since larger hard drive enables you to save more files.
Crucial BX500 comes with five different capacities, yet Crucial MX500 comes with different capacities. Both of them are available in capacities up to 4TB. The exact capacity options vary by model and form factor.
| Crucial BX500 SSD | Crucial MX500 SSD | |
| Capacity | 120GB, 240GB, 480GB, 1TB, 2TB, and 4TB | 250GB, 500GB, 1TB, 2TB, and 4TB |
So, as for Crucial MX500 vs BX500, there is no big difference in capacity. But Crucial BX500 provides more choices and you can choose any one based on your actual needs.
3. Crucial BX500 vs MX500: Performance
When choosing a hard drive or a solid-state drive, the performance would be one of the most important factors to be considered. An SSD with good performance may enable your computer to run faster and improve PC performance.
So, here, we will take about the performance of Crucial BX500 1TB and Crucial MX500 1TB.
| Crucial BX500 SSD 1TB | Crucial MX500 SSD 1TB | |
| Sequential Read | 540 MB/s | 560 MB/s |
| Sequential Write | 500 MB/s | 510 MB/s |
| Random Read | N/A | 95,000 IOPS |
| Random Write | N/A | 90,000 IOPS |
All statistics are from the official site of Crucial, but the random read and write speed of Crucial BX500 SSD are not mentioned. On sequential speeds, the two drives are relatively close.
A more significant distinction is that the MX500 uses a DRAM cache, whereas the BX500 uses a DRAM-less design. This makes the MX500 much better suited for heavier or sustained workloads. DRAM stores data maps for faster file retrieval and improved performance.
In addition, you can also choose to test the disk performance by yourself through the Disk Benchmark feature of MiniTool Partition Wizard.
