Never Trust Tech Support

[moriarty]

We were wondering why an appliance was suffering poor performance after a drive replacement. Was a full stack of intel ssds. Replacements were from Micron.
Trouble shooting hdparm to controller caches showed full performance ~ 330MBs accross the board. Did a nwipe and discovered one of the replacements was taking 3 times longer to wipe. Swapped to a different bay and wiped again. Problem followed drive. Picture is the result. Not one fault mentioned by smart and disk life is less than 100 hours. Firmware is updated.

Just a friendly PSA that even though your manufacturer swears compatibility on thier mother’s unmentionables. Performance parity matters. Replacement drives need to be the same vendor and model. Just like a bad apple ruins the barrel. One derpy ssd spoils the pool. Now imagine trying to explain this to enterprise tech support workers who are neither technical nor supportive.

Micron > Intel as of recent

bathtub curve, drives fail in the first 90 days or in 3.5 years

EXACTLY how SSD’s fail
It’s fuckin indescribale and frustrating as shit.

Pretty sure I mentioned this a few hours ago…

Looking for new m.2 SSD

If it’s a 2020 or 2021 drive, it’s likely just trashed and done. But we’ve seen an increase in Samsung failures. Drives are cheap, data is not. If a drive is suspect, we pull and will use it for one of my media PC’s at the house. Some are great and we never see another problem for a couple years but most are no longer recognized within 1 year …

yep, welcome to the fuck all of enterprise maintenance

You did not mention server age, but we replace every 3 years to maintain uptime.

you have shit tech support / MSP
Seriously consider local, but genuine pros. Ask obscure shit you can’t google quickly.

Now I can picture someone saying:

You create billable hours.

I use them.

We are not the same.
