Combining Mix Use (MU) and Read Intensive (RI) SSD in same Raid array

cn flag

I know you cannot combine mixed drive types in an array eg. SAS/SATA or SSD/HDD. What about identically sized SATA SSD in the MU and RI options?

RAID-5:
4x P18434-B21 - HPE 960GB SATA MU SFF SC MV SSD - Mix Use, currently installed
4x P18424-B21 - HPE 960GB SATA RI SFF SC MV SSD - Read Intensive, want to expand with these.

The only difference in spec I can find is the write cycles each one can handle, so all else being equal, the RI drives are more likely to fail before the MU simply by exhausting their write count.

Maybe not best practice or recommended, but any issues I'm missing?

thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
