The Crucial BX200 (480GB & 960GB) SSD Review: Crucial's First TLC NAND SSD
by Billy Tallis on November 3, 2015 9:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionately more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance should never drop all the way down to the steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
The higher proportion of writes on the Heavy test as compared with The Destroyer sends the BX200 to the bottom of the chart. The difference in performance between running the Heavy test on a freshly-erased drive and a completely full drive is atypically small, showing that the poor performance cannot be due to a mere lack of sufficient overprovisioning.
Until the BX200 came along, there wasn't much spread among SATA drive for average service time. The painful write performance shows up very clearly here.
With 8.8% and 10.7% of operations taking more than 10ms to complete, the BX200 will clearly be noticeably slower than most modern SSDs under moderate and heavy load.
Power consumption is once again dismal, as the drive is apparently spending way too much of its time on its relatively ineffective garbage collection.

I see the MU02 firmware for this drive is out, are there any plans to retest?LarsBars - Tuesday, February 2, 2016 - link
The BX200's are getting cheap now, and they have a new firmware update, MU02. Any chance that you could re-run the BX200's through the tests and see if anything is improved? Thanks!Amoro - Monday, April 11, 2016 - link
I don't see the point since it only states stability/reliability improvements and doesn't mention anything about performance.Release Date: 1/12/2016
Corrected SMART attribute threshold values
Improved general reliability and stability
Minor Bug Fixes and general reliability and stability Improvements

I dont know how your IO tests throughput numbers are so high compared to MX100 or MX200. As soon as I tried to clone a 1TB drive for my wifes laptop the write speed dropped to 60 MB/s or less, clearly slower than the HDD it was meant to replace. BX is a truly horrible drive for write performance, I will not recommend to anyone. I dont know why it was not highlighted in your review.dh33r4j - Thursday, August 25, 2016 - link
I got the 480GB for £73 ($95) during lightning sale from Amazon. When the price is right, I think it becomes worth it. For someone moving from a HDD to SSD, I coudn't say no to the offer.
