Yep! What's crazy is that some of these older NAS units I have that were never tested with larger drives work with them fine. So at 28TB, a little 4x drive NAS unit is already 112TB, and as the drive capacity scales out to 50TB, that will be 200TB in the size of a toaster. :D The question is what to do with all that space besides making it 4x redundant, lol.

Wait till 8K content becomes mainstream... (especially the kind that seems to require consent that "I'm over 18"...). A standard theatrical release (uncompressed) could be 200GB. A TB will only hold 5x of them. So...100TB.... pfft.

:)

Edit: "older NAS units I have that were never tested with larger drives work" - I think once we crossed that stupid 3gbps barrier for SATA/SAS, drive support is essentially unlimited, as long as it follows the standard SAS/SATA comms.

I think I mentioned somewhere, in a different thread - I'm still using my old-ass Chenbro NR40700 chassis as my main workhorse storage units. These are only 6gbps, but...they hold 48x HDDs and cool quite well. They were released in 2014...so, almost 11 year old already. And they still work like champs!

Between my two storage chassis, I'm at ~2PB and counting...

lol, yep that industry was the first to bring video online, 3d video, interactive...errr...entertainment, AI 'companions', so it doesn't surprise me they're at the forefront. It's got my respect for where it's paved the way technology wise, lol.

I love older stuff that just continues to work like that. I've an older 12-bay Lenovo NAS like that, and it even supports SAS drives even though the documentation says nothing about it, lol.

2PB?!?!? I'm a wuss--I think my critical data set is just under 10TB, lol. Everything else is for backups--lots and lots of backups, lol.

P.s. that reminds me…I need to do a blog post on ZFS and…hardware raid controllers…

The amount of FUD online about this topic is astounding.

About half of that 2PB is replicated across the two nodes, for my business. But yeah, the fact that I can have that much storage sitting in a corner of my basement, and not costing a kidney…is …well…wow.

It is quite amazing! I still remember a scene from Wargames (I think?) when they walk through a room full of washing machine sized hard drives that stored MBs of data. :eek: And what really gets me is the physical size reductions. I've seen decades of paper documents and file boxes fit on just a single 3.5" hard drive--and this is with documents scanned at 600dpi full color too.

Yes, that would be awesome! I didn't realize there's so much confusion on ZFS when it comes to hardware.

Almost 2 Days to replace a 14TB Drive and that was for a Mirror VDEV ...

with ZFS?? That seems...weird?

I'm using 22TB HDDs currently in my arrays and the Adaptec can rebuild a 22x HDD RAID-6 array in less than a day. That's a ~500TB array.

Yyy? 22 wide-Z2 ?, you remove 2, insert new ones, and got it rebuilded within 24hrs? This is what you meant?
Even if you consider these 2 are going to be written simultaneously, given 160MB/s average, thats 36hours. Yes, linear thing is a thing, but can it be linear during rebuild ? Then even with 250MB/s (that i find super not realistic in long term, since HDD has this kind of performance only in small area) thats 23hours.

Last time i rebuilded 5wide Z1 build of 20TB drives it took close to 60h...

Yes, ZFS (on Proxmox VE Host). It is a dual striped Mirror (2 stripes x 2 Disks Mirror each)

There was some Activity & Writes going on although to be fair I temporarily stopped those Activities but the Speed never went up, so I just re-enabled since it didn't make any Difference.

It started Resilvering at the amazing Speed of 2.0 MB/s and steadily increased to around 70.0 MB/s after like 10 Hours.

But the first 4 Hours or so it was < 10 MB/s, probably because the initial Sectors / Tracks have a much smaller Bit Density since the Radius is much smaller, while the more towards the outside the Head goes, the more Bits it can Write/Read per Rotation (~ constant 7200 RPM).
