in theory same as any other. except that it will take a long time . i guess if you have 20x disks vs 6x disks, i guess the probability of at least 1 disk fail would be greater out of 20 vs 6? still its just scary to see how amount of data loss can result from one disk down.but how are those 10tb going to rebuild if one drive fail?
I think they support Rebuild Assist (introduced with the sata v3.2 specification, there is also a sas equivalent): https://www.hgst.com/sites/default/files/resources/HGST-Delivers-Rebuild-Assist-Mode-for-Faster-RAID-Recovery-WP.pdf.but how are those 10tb going to rebuild if one drive fail?
It simply isn't possible, for a number of reasons. Assuming a somewhat more modern technology, like the CDC 9766 (12 x 14" platters, 3600 RPM, 300-ish MB), you have a couple of problems:How insane would it be to go back to refrigerator-sized 5-ton HDDs consisting of 20x 4 foot diameter platters driven by a 10-hp motor using today's technologies spinning at 7.2k, 10K, or even 15K RPMs? Have it so you could repair them with ease and still keep them dust free. What capacity would that be? using 1.2Tbpsi? However you look at it, that would be ... Crazy!!!
