I have a Crucial MX drive as my system drive for years. Got BX used one for external storage. It gets EXTREMELY HOT! 50c just doing nothing! 80c+ under load. And yeah, after the cache is used up, the write speed drops to and a pathetic 50-60Mb/sec. Huge disappointment from Crucial. Not worth the money.

Much better than Kingston A400

I used this 250GB SSD to speed up my old laptop (installing Windows 10 on it) and it works great. I have 180GB of free space, so I don't know if performance stay consistent filling it up (since it lacks a dram-cache). If you need an SSD for a primary machine, get an MX500.

It's a great SSD for the value and performance.

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
