Having PLP might correlate with having good performance, but it's not
the reason for good performance and good performance is not the reason
you want PLP. It's just that both things are present in many enterprise
SSDs, I'd mention that explicitly to avoid potential confusion.
When it comes to sync writes, it is definitely one reason for the good
performance ;)
But yeah, let's think about it, what about the following?:
Enterprise grade SSDs are recommended for good performance. Checking for
Power-Loss-Protection (PLP) is a good way to avoid consumer grade
SSDs. The use of consumer grade SSDs is discouraged.
Not too happy with that either, but phrasing it correctly and succinct
is an art in itself.

storage technology and cluster setup.
