The problem identified in this article is _NOT_ TRIM support. It's
QUEUED TRIM support. It's an exotic firmware feature that is BROKEN.
Suffice to say, if Windows doesn't exercise an exotic feature in PC
hardware, it may not be well tested by anybody!

I don't think TRIM is to blame here.
1) From the article, what can we see that Ext4/Linux actually did wrong
here? - Is it that the TRUNCATE command should be abandoned completely, or
was it how it matched supported/unsupported drives, or something else?
Mariano was being a jerk by assuming it is a bug in ext4 or other
code.
Wait, just for my (and I guesss some others') clarity, three questions here:

Another question is of this buggy TRIM, but I'm afraid this may be
hard fight even with replication and checksumming filesystems
(ZFS/HAMMER/BTRFS).

If I wanted a setup like that i'd just use RAID, note the obvious - write
performance will be the same (or possibly slightly slower due to the added
RAID layer)

Paranoia over SSDs messing up is why I got hybrid drives - still get a
decent performance boost but all my data is on good old fashioned magnetic
platters
