Parity rebuild will only take a week....
A week before next month
Obligatory hint that SMR isn't suited for RAID systems.
Tape on a platter, basically.
A better way to word it is: SMR is only suited for archival usage. Large writes, little-to-no random writes.
Wonder what happens if you throw them in an unraid BTRFS/jbod configuration with a CMR parity drive.
Slowdown and data corruption?
My 6TB drive just died. So I'm in the market for a new one.
sorry but these aren't 6TB
Mebbe the 26 one is just 3-4 smaller drives inside it?
You joke but that's sorta how it works for some HDDs lol
I hope you think of having several platters, not real drives :-D
this is great news! I'm running low on space on my 20tb now.
My Jellyfin just quivered…
I’ve been looking to buy a couple 24TB drives. Hopefully, this pushes their price down.
Peertube instance owners rejoice!
Or just people who download porn.
That's... a lot of porn.
If you eyeballing these, please remind that these babies tend to be LOUD AS FUCK, so might not be suitable for home server use.
Just don't put it in your bedroom. All those dead skin cells wouldn't do good to it anyway.
Since when is dust a concern for hard drives??
I was talking about the server in general
Drives like this are hermetically sealed with an inert gas like argon or helium on the inside. Even the presence of oxygen and nitrogen molecules can compromise the drive. If dust is getting to the moving parts of your hard drive, it's toast no matter where it's installed.
Are they any louder than any HDD from the last 30 years?
If so, im actually curious why that is
Edit: fixed to say HDD not SSD
My NAS uses a pair of SAS drives, and they make noises at boot up that would be concerning in a desktop. They're quite obnoxious. But I keep them in part of the house where they don't bother me.
When will it be commercially available though? Supposedly Seagate has had 30TB drives out for the better part of a year, but I can't find anything larger than 24TB actually available for purchase.
I'd guess that they're commercially available but only for hyperscalers - large companies like Google, Amazon (AWS), etc that need a huge amount of storage.
Assuming that these have fairly impressive 100 MB/s sustained write speed, then it's going to take about 93 hours to write the whole contents of the disk - basically four days. That's a long time to replace a failed drive in a RAID array; you'd need to consider multiple disks of redundancy just in case another one fails while you're resilvering the first.
My 16TB ultrastars get upwards of 180MB/s sustained read and write, these will presumably be faster than that as the density is higher.
I'm guessing that only works if the file is smaller than the RAM cache of the drives. Transfer a file that's bigger than that, and it will go fast at first, but then fill the cache and the rate starts to drop closer to 100 MB/s.
My data hoarder drives are a pair of WD ultrastar 18TB SAS drives on RAID1, and that's how they tend to behave.
This is for very long sustained writes, like 40TiB at a time. I can't say I've ever noticed any slowdown, but I'll keep a closer eye on it next time I do another huge copy. I've also never seen any kind of noticeable slowdown on my 4 8TB SATA WD golds, although they only get to about 150MB/s each.
EDIT: The effect would be obvious pretty fast at even moderate write speeds, I've never seen a drive with more than a GB of cache. My 16TB drives have 256MB, and the 8TB drives only 64MB of cache.
This is a most excellent place for technology news and articles.
