Samsung SM863

[Alessandro 123]

Anyone using Samsung SM863/SM863a SSD from a long time ? Any thought?

Currenty, it cost about half an Intel DC S4600, but the Intel has a lower DWPD.
The real comparison should be made with Intel DC S3610 but this one is EOL, so is Samsung SM863 a good enterprise drive?

Any sudden failures and so on ? Intel SSDs are considered the most reliable SSDs

We use them in our testlab.

I see, but a test lab is not exactly a production use.
I'm looking for real production use in a DC. (something like: we use them from 5 years, not issues at all, or something similiar)

I doubt that someone use these drives for 5 years already (AFAIK they were announced in 2015...).

Ok... 3 years then

Tom, does the wear level indicator wears out faster? Should we worry albeit the total TB written is not reaching the warranty limit?

Not exactly your model, but our SAMSUNG MZ7WD960HMHP have 3,5y in a production server with ~20GB/day and still 99% health.
