With where we're at with SSDs chasing the performance dragon... I suspect some deception is at play!
The DRAM caches are pretty hefty compared to metadata, so I wouldn't be surprised - though that's about my extent of understanding.
Even then, though - other filesystems are certainly more durable, dealing with whatever these drives are doing.
FWIW, this was with four Sabrent Rocket 4.0 Plus drives in RAID10 with 4K sectors. I'm not sure if these are particularly well known one way or another for deception/trickery
They hold up just fine with either dm-raid or native LVM raid10 under more traditional filesystems (I tested EXT4/XFS, using the latter consistently)
