Question When to retire an SSD?

[Ollie_7]

I've had an MX300 as a cache drive in my unRAID box for 6 years. Was new when i put it in. It's at 43TBW. According to a calculator i found. Manufacturer says its limit is 80.

Anyways, i am buying some new spinners and i'm wondering if i should replace my cache drive too. I'd rather spend the money on more array drives but it seems smart to replace it, no?

Why replace the SSD when your box's hardware is the same? Do you need more cache quantity?

Not sure why you'd replace it.

I have it's ancestor, the MX100.

Capacity 128 GB.

TBW rating 72 as I recall.

So-called "remaining life": 73%, signifying not much.

I've written 45 TB in 7 years and likely will use it indefinitely as long as it works and has the required capacity.

Guess i'm just used to old hdds failing due to age. Feels weird using storage 24/7 for over 6 years. I've never used an SSD this long. with almost no power off time. Usually retire spinners around now shrug guess i'll keep it

SSD can last a decade if you don't write on it excessively.

Being a caching memory, your SSD probably has more reads than writes, and reading doesn't affect the SSD's memory chips.

I write to it quite a bit. It runs VMs. Everything i write to the arry goes there first. Plex does everything there too.
