So I got a report that there was 1 unreadable (pending) sectors on a disk, so I began the process of replacing it. All went well, and now it's resilvering.

Well, it *was* all going well, but it seems the last 300 GB or so have become very slow to scan over. It started out at ~50 MB/s, but is crawling along at 5 MB/s as evidenced by the Reporting - Disk tab:

Do I have cause for concern? My assumption is that due to more small-ish files and snapshots being at the end that this is why it's slowing down, but I wanted to be sure...

It's hard to say without specifics. Expect it to take about as long as the scrubs,

Yeah I've never watched how long it takes to do a scrub, I just know they've been happening regularly and that's what triggered the alert in the first place (well actually smartctl, but pedantics)?

I guess what this has taught me is that the filesystem does the checking in a different way than simply scanning everything sequentially on the disk itself (duh) so ReadWrite speeds will vary.

There might be additional lurking problems among the drives.
By posting the entire output of
Code:
smartctl -a /dev/adaX
for each drive, using brackets for readability, clues might emerge.

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
