Seagate's roadmap teases 100TBs of spinning rust by 2025

I guess my source wasnt wrong

He was taking about parity RAID rebuilds. That would take such an obscene amount of time with 100tb drives.

How many consumers are going to being running any kind of RAID with 100TB drives? 😲

 

By the time you get into arrays that huge, there are far better redundancy schemes that wouldn't take as long or it wouldn't matter if it did.

 

Btw, back when I still used HDDs, it took me only three hours to clone a "full" 4TB HDD (I had 15% free space on it, the recommended amount for best operation). That's 75 hours for 100TB, only a little over 3 days.

As long as anyone is oppressed, no one will be safe and free.

One has to be proactive, not reactive, to ensure the safety of one's data so backup your data! And RAID is NOT a backup!

Again, there's a very big difference between some form of mirror'd RAID and parity RAID. Parity RAID with a 100TB drive would take months and have quite a good chance of killing another drive in the process.

Cloning is not a mirrored RAID (aka RAID 1).

Cloning is going to be in line with rebuilding a RAID 1 array -- which is significantly faster than rebuilding a parity array. It's not even in the same ballpark.

I just looked it up and I stand sit corrected. A 4TB drive in RAID 5 or 6 will take ten hours to rebuild one drive. That amounts to ten and a half days for 100TB.

 

I agree that that the time to rebuild even RAID 6 leaves data too vulnerable (yet another reason why RAIDs should be backed up). it's also why commercial server farms don't use RAID anymore.

 

Again, however, not very many consumers will ever need more than 100TB of storage and would be better off to just use simple, separate backups unless continuous operation is absolutely essential (not just desirable).

It's 10 hours assuming you can sustain the full write speed of the drive, which you can't. You still need to do parity calculations, which are intensive and the drives are generally in use on top of it all.

hard drives are outpacing consumer storage needs so fast lol

 

I mean even 16TB drives that we have already.. don't see them too often outside of data centers.

So this will be great for enterprise.. but I don't see consumers caring much tbh. I'm more interested in having 1TB ssd's for $80-120. At that point... who the heck needs a hard drive? like why even? I'll just cram 4 2TB ssd's in my NAS and call it a day...

I've had 2TB HDD when they first came out. Had it for like 7 years iirc. Now I'm on 2TB SSD and I don't really see the need to have a bigger one.

If only QLC SSDs can arrive sooner.

Even though Samsung has been making reliable SSDs since the 840 EVO fiasco, I'm a bit leary of the new QLCs supposedly coming out next year (Samsung is notorius for being late with new product releases). I would prefer to wait around for a year or two to see how they pan out. Look at how long the 750 line lasted before Samsung dropped it.

Well the micron 5120 QLC came out recently but I don't know what the price is.

I haven't seen them for sale anywhere yet but I question what their quality will be even more than the Sammy QLCs since Micron is using Marvell controllers (Marvell has never impressed me with anything they have).
