Agreed, the first gen MX500 with M3CR023 fw proved IMHO to be the second most reliable SATA SSD 2.5" form factor with the Samsung 860 range SSDs (860 Evo / Pro).

Sadly, the MX500 is now difficult to find in western europe. Only lower grade BX500, still quite reliable but not as fast as the MX500 with cache + DRAM.

Had quite a lot of controller issues (become sluggish for periods of time) with the sandisk/WD ones like green/blue and SSD plus.

Huh, I've had the opposite experience with the BX500. Hit a bit hard on them and the SSD drops off the bus. Or fill them up to 80% and witness them crawl to a stop. Dirt cheap drives, but don't ask too much of them.

I wrote the BX500 ils easier to find than the MX500, not that it is better. Obviously the BX is worse than the MX, having no SLC cache.

Oh I never said you wrote it's better, your message is quite clear :)

Just that I would not really compare the two. The BX500 is the only Crucial SSD I've ever had troubles with and kinda eroded my trust in the brand. My >10 years old M4 is still working like a champ, so does my MX200.

DRAM-less SSDs are a plague that is very hard to avoid, as it's never mentioned in the spec sheets.
