OK, will check it out :) I think I read somewhere that SMART data aint available in the same way as regular SATA drives. True or false?
Its not 100% identical to sata drives but close:

Now to get used to the higher power consumption. I guess I will notice running 8 x 6TB drives idling around 7W vs SATA drives at 2W.
Good thing 9 out of 12 months in Norway requires heating your house more or less ;P

@Rand_ I think it also depends on whether the manufacturer submitted their drives for inclusion in smartmontools. To my knowledge HGST does not do this for their Enterprise drives (at least they didn't in mid-2018).

@MortenB if you have any left you can just Norgespakken them to me as my offer got rejected :p

Really? Will need to check on the ssds i have, never knew that. Or is it only HDDs?

I only checked on HDDs so can't say anything to SSDs. I was running some SAS HGST HDDs with a SAS backplane and they could only be diagnosed with the HGST utility, did not report any raw SMART attributes with smartctl.

SAS can be cheaper than SATA (this deal for example). Not to mention that once you get SAS controllers, backplanes etc. you can get access to enterprise hardware for cheap. You just have to look around and be patient. It puts those 10GB no warranty Bestbuy shucking deals to shame when you can pickup a far superior barely used 10tb 7200rpm HGST enterprise drive for less.

SAS3 in particular has the bandwidth to handle SSDs, it's a cleaner more reliable system overall... otherwise you have to go NVMe (which is still limiting) or go back to 6g SATA which caps at roughly 500mb/s for the time being.

SAS is a worthwhile investment and not going away anytime soon. If anything, even better deals are coming as datacenters move to NVMe.

How cheap are 8/10TB HGST SAS drives per TB with the best deals that show up now and then?

From my experience the 6Tb is the largest capacity where SAS drives can be found cheaper than their SATA counterparts. I am yet to see any SAS versions of 8Tb+ drives selling for less than SATA.

This is why bulk of my drives is still 4Tb SAS.

4Kn is ideal and works with all modern machines and operating systems.

https://support.microsoft.com/en-us...t-policy-for-4k-sector-hard-drives-in-windows

Basically you have three formats:

512n (legacy- older hard drives and operating systems)
512e (crossover standard with 4k physical sectors being emulated as 512 - most low end consumer grade hard drives., i.e., the WD Gold line up to server hardware., etc.)
4kn (4k physical sector size without emulation- most "high end" consumer grade hard drives and beyond. i.e., "WD Red Pro" the new standard that all modern systems support- windows 7+ etc.)

It seems the seller has another batch of about 104 but he jacked the price up to $99.99. Have anyone received these drives yet I wanted to see the smart data and drive health.

Lol, that o/c applies only if you want to ship to EU;)

We used to do similar calculations and graphed them to see what the limit was on per drive cost back in the day when we had a Syquest 44mb drive and 200mb drive. We ran the same calculations for the Iomega Jaz and Syjet 1.5gb drives when they came out. When I learned about differentiation in calculus, I was able to make a formula that would immediately tell me the sweet spot in the log curve for a particular set of drive cost parameters, but I can't remember any of the math anymore. :oops:

My dad's a retired mechanical engineer who's always complaining about being bored, so I'll see if I can get him to re-create it. :D
