Score: 75/100
SanDisk Extreme 500GB
Score: 35/100Rankings

The Crucial BX500 1TB is a budget-oriented SATA SSD that delivers solid sequential performance and high capacity for everyday computing, but it lacks DRAM cache and hardware encryption.

The SanDisk Extreme Portable SSD 500 GB offers near-top-tier NVMe speeds in a rugged, IP55-rated case with built-in hardware encryption, making it ideal for creators on the move. Some users note a flimsy USB-A adapter, occasional early failures, and thermal warm-up under heavy use.

Products in the top-left offer the best value (high score, low price).

Professional reviewers acknowledge the BX500 as a solid entry-level SSD that delivers the expected SATA performance at a low price. PCMag notes that while it performs well in benchmarks, the lack of DRAM cache and shorter warranty make the MX500 a better overall value. Gagadget praises its affordability and real-world speed but warns against heavy write workloads due to the SLC cache limitation.
Everyday users appreciate the noticeable speed boost over mechanical drives, the ease of installation, and the included cloning tools, while complaints focus on the sharp write-speed drop after the cache fills and the absence of mounting hardware.

Professional reviewers commend the Extreme Portable SSD for delivering near-top tier performance (1050 MB/s) in a rugged, IP55-rated package, emphasizing its suitability for 4K video editing and secure data handling. They note the absence of a metal heatsink as the main drawback, but conclude that passive cooling is adequate for typical use cases.
Everyday users love the SSD's tiny footprint, durability, and speed for photo/video backups, often highlighting the handy carabiner loop. Complaints focus on occasional early failures, a flimsy USB-A adapter, the default exFAT format, and the device warming under heavy use.
“quite difficult to find the same volume and speed for the same money.”

“significant performance improvements over HDDs, especially in boot times and application loading.”

“Slow write speeds during large file transfers after the initial cache is filled.”
