On 2nd thought, I'd consider the greens something like a "hostile witness" in legal jargon. Relegate them to only ZFS or btrfs (or ReFS maybe, unclear) for "raid" like pooling or redundancy. The drives themselves are inherently suspect so a suspicious grand inquisitor of a file system seems like an appropriate match, to constantly 2nd guess them.

But still, once a drive is asked to retrieve an LBA, so long as the drive eventually reports it back correctly, the file system won't correct that sector merely for a delay, even if it is up to 2 minutes or whatever it is. So, filesystem choice doesn't really solve the delay problem. You just have to obliterate the disk periodically with zeros or secure erase.
