Re: LSI SAS9211-8i

That's my assumption - I was able to revert back to very old firmware revisions by wiping the card completely (which you need to do to switch between IR and IT modes in some cases).

Re: LSI SAS9211-8i

I've found the only real thing you need to match up is the controller type - it won't let you flash something incompatible in general, and as a rule, they're pretty amazingly easy to re-flash even if you screw up entirely. I've wiped the card firmware/BIOS completely clean to recover from errors (wh...

Non-bootable update for me. Hurray. My desktop updated last night on shutdown. On boot today, no video, monitor says "no cable connected". Wait a few minutes, it restarts on its own, and I see "Reverting to previous version of Windows" and get a "Oops, that didn't work"...

Re: LSI SAS9211-8

Flash to IT mode for any kind of software raid (the best kind) and try to use a version recommended by the driver if any (mostly a thing in *BSD) as sometimes you can be "too new". If you don't need to boot off any drives on the card, you can also flash it without adding the option rom. P...

Re: LSI SAS9211-8

I recommend bumping the firmware if it's easy in your environment, there are a few known bugs on older (pre version 15) firmware that are possible to hit in somewhat normal use. Error recovery from misbehaving drives is much better in my experience with the newer firmware revisions as well. FreeNAS ...

That review is over 2 years old. Early drive-managed SMR firmware did indeed suck. I take some pride in having helped them optimize that firmware, if only from a "dammit make these things not suck or I won't buy them, here's a few simple tricks" perspective. Well, it's not like anyone'd u...

Re: Threadripper motherboards, tough choice.

Newegg reviews, like Amazon reviews, are generally only useful if there are hundreds of reviews. I'm still amazed people take the time to put up a "review" that's basically "I bought the wrong thing" or completely attributed to user error.

That's somewhat surprising. Modern drives store on the order of 2 MB/track; if we assume a 5 platter design (10 surfaces), that's 20 MB per cylinder. With only "tens of MB" per zone, you'd be overlapping only 2-4 cylinders in each SMR zone, leaving a lot of potential capacity on the table...

Assuming you stick with lower RPM, I don't think you will get a comparable speed boost this time, as I believe the 8TB models use more platters with only modest increase in linear bit density. Also make sure you get a PMR drive, not SMR. Performance of SMR drives for non-sequential writes is abysma...
