While shopping for an SSD I have noticed that some manufacturers promote their "Pro" models as the ones sporting ECC data protection. Those manufacturers do not mention ECC in their budget models descriptions.

However, Wikipedia article on flash memory states that "NAND relies on ECC to compensate for bits that may spontaneously fail during normal device operation."

So the question is does any SSD device use ECC behind the scenes for its normal operation and is that ECC "feature" just a marketing ploy?
