A week before next month
this is great news! I'm running low on space on my 20tb now.
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
Obligatory hint that SMR isn't suited for RAID systems.
Tape on a platter, basically.
Wonder what happens if you throw them in an unraid BTRFS/jbod configuration with a CMR parity drive.
Slowdown and data corruption?
A better way to word it is: SMR is only suited for archival usage. Large writes, little-to-no random writes.
I wonder how the read performance would be.
If you know the format of SMR, then you can trivially see the read performance is not impacted. Writing is impacted, because it has to write multiple times for each sector write (because of overlapping sectors that allow the extra density).
Impacted write performance, coupled with hdds are generally slow with random writes PLUS the extra potential for data loss due to less-atomic sector writes, makes them terrible drives for everything except archival usage.
Think of the parity!
