Hi
I bought SSD Intel 545s SATA 512 gb, but then Crucial mx500 came on sale. I can return 545s and buy mx500 for the same price. I want to know which one has better data protection technology in case of unexpected power loss. I know that these drives do not have enterprise level protection, but from these two drives, I would prefer the one that has better data protection from power loss.
The manufacturer claims that the mx500 has "Integrated Power Loss Immunity". The drive has a large number of capacitors on the board, which, according to the manufacturer, are discharged in NAND to protect data if the drive loses power while writing a second pass of more data to the same cells. As I understand, it only protects data-at-rest. Data-in-flight and DRAM cache will be lost.
Intel 545s does not have "Enhanced Power Loss Data Protection" in the specifications, but surely there is some kind of "not enhanced" protection technology acceptable for consumer drives, but I did not find any mention of it. Advantages in comparison with the mx500 I noted the presence of technology SRAM ECC and end-to-end data protection. I don`t know whether these technologies have an impact on data protection in case of unexpected power loss. Also there is a smaller number of capacitors than has mx500.

- Does 545s drive have power loss data protection technology presented by mx500? If not, does 545s have an analogy to this technology?
- Which of these drives, given the technologies they have, has better data protection in case of power loss?
