Re: LSI SAS9211-8

I have three of this card (two in my FreeNAS server, one flashed for RAID duty) and one of the PCIe 3.0 version of this card card (well, in IT mode, the hardware is the same) in my desktop. They work pretty nicely, though I added a larger heatsink to mine since it got pretty darn toasty in a non-ser...

Re: I need some help, gerbils! Which are the quiet consumer hard drives?

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...

Modern SMR tech is a lot more tolerable than the 5 TB Archive drive that debuted first. Those things are pigs and only useful if you can *really* tailor your workflow.

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.

Re: New drive suggestions?

For Seagate drive-managed: Certain 3 TB and 5 TB 2.5" drives are SMR (it's harder to tell for 2.5" drives). This obfuscation really annoys me. Archive 5 TB and 8 TB 3.5" drives are SMR (if you shuck one, it's a 99% chance it's SMR). The 5 TB drive is measurably worse in every performa...

Re: New drive suggestions?

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...

Does "drive-managed" mean they're zeroing out empty space like TRIM on an SSD? No... SMR drives don't have wear leveling issues, but (like SSDs) some trickery is required to make them look like a "normal" random-access disk device. SMR drives are divided into "zones", ...

I will likely be dealing with HGST host-managed SMR drives in the medium-term, unless SMR as a tech falls out of favor. I highly doubt SMR is going to fall out of favor - I'd bet that it'll be in every drive with the exception of NL-SAS in the next few years as cheap NAND continues to push on the H...

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...
