Yeah Samsung is honestly garbage these days trading on their former reputation for quality. They have horrible, I mean the WORST QA, out of any major brand across the their markets. You have a greater chance of having an issue than not, they do not have any sort of decent RMA process and will just provide patchwork “fixes” consistently until someone’s product runs out of warranty. There is a legendary story of someone trying to get their G5 Flagship Gaming Monitor fixed and sent it in like 13 times and NEVER getting his product fixed or replaced until they hit the warranty deadline. The SSD issue from earlier this year is another great example of complete incompetence.
I would NEVER consider a Samsung product given the alternatives. They all have great specs and you have a 50/50 shot of getting a “good” one but that’s still a ton of risk for a premium priced product.
The MX500 is pretty much the market leader as far as older SATA SSDs are concerned, with PLP capacitors, very generous NAND overprovisioning, and an onboard DRAM cache if I'm not mistaken.
The BX series is pretty budget oriented though, those are just standard 3D nand SSDs with no PLP, no DRAM.
If storage TBs are the concern, Samsung absolutely offers higher capacities than the MX series last time I checked
Edit: forgot the most important piece of info... Crucial is essentially Micron, the RAM and SSD manufacturer. They only sell things that Micron manufactures, so they don't sell SD cards, blank CDs and other generic storage stuff
Micron is also an OG memory inventor and still makes some crazy innovations in storage space. Crucial is their performance brand and it's leagues better than recent Samsung.
