Hewlett Packard Enterprise (HPE) sent out a warning (opens in new tab) Friday that some of its enterprise SAS-SSDs will brick themselves after 40,000 hours of operation. Based on the sale dates of the afflicted parts, most are expected to reach the 40,000-hour mark in October 2020 at the earliest.
To fix the problem, system administrators must install the HPD7 (or newer) firmware (opens in new tab)update. This update is considered critical, and failing to install it will result in unrecoverable data loss.

HPE did not mention in its bulletin what the exact cause of the problem is. Some might suspect that HPE implemented a timer-based obsolescence at such a non-random figure, but that would simply be too obvious. The issue is said to have been reported to HPE by one of its unnamed SSD manufacturers.
HPE ProLiant, Synergy, Apollo 4200, Synergy Storage Modules, D3000 Storage Enclosure and StoreEasy 1000 Storage are systems that may contain SSDs with this bug.
|HPE Model Number||HPE SKU||HPE SKU DESCRIPTION|
|EK0800JVYPN||846430-B21||HPE 800GB 12G SAS WI-1 SFF SC SSD|
|EO1600JVYPP||846432-B21||HPE 1.6TB 12G SAS WI-1 SFF SC SSD|
|MK0800JVYPQ||846434-B21||HPE 800GB 12G SAS MU-1 SFF SC SSD|
|MO1600JVYPR||846436-B21||HPE 1.6TB 12G SAS MU-1 SFF SC SSD|
Given that many SSDs in an enterprise environment might be running in RAID arrays, it is especially critical to apply the update: many of the SSDs will be failing simultaneously, and without a non-RAID backup, all data will be unrecoverable surpassing 40,000 hours.
In November, HPE issued a similar update (opens in new tab) for a different set of SSDs that would fail after 32,768 hours of operation.
And someone will bitch about it.
"They shoulda told us! Imma sue!"
They DID tell you, and "enterprise SAS SSD " means you have a backup, right?
I have examined these firmware patches here:
AFAICT, both the Dell and HP SSDs are OEM versions of SanDisk's Lightning Eco Gen. II SAS SSDs. WD/SanDisk has issued its own patch, but it's not easy to find. In fact when I examined the payload, I discovered numerous references to Huawei. This led me to wonder whether Huawei was the actual manufacturer, or perhaps Huawei was an OEM and WD mistakenly released Huawei OEM firmware into its retail channel.
Even stranger is the 32768 hour bug which affects HP OEM SSDs but not Dell or Samsung (who is the original manufacturer):
Here is a user who has lost 4 x Samsung PM1633a 15.36TB SSDs all at once:

I suspect that Samsung's retail versions of the same drive are also affected by the same bug, but Google turns up nothing.
The SSD in the reddit thread appears to be an OEM HP model. However, it's not clear whether this model number was one of those listed in HP's bulletin.
