- gruez 6y agoWhat's the current state of SMR technology? I noticed that all the high capacity drives (ie. 16+TB) are all CMR, and SMR drives top out at around 8TB. Is there a reason for this? Did WD and seagate stop developing SMR drives after the consumer backlash?
- brokenmachine 6y agoImagine how long it would take to write 16Tb to an SMR drive... That's probably why there's no really large ones.
- gruez 6y agoFor sequential write workloads it shouldn't be much slower than CMR drives. They only get bad performance when overwriting existing data, especially if they're randomly spread out.
