SMR for consumers, is only good for hybrid hard drives, which have GBs of cache to cache the writes.
Like the Seagate FireCuda 2TB laptop drive with 2 1TB platters.
But otherwise, it'll be HAMR that'll bring up to another leap in bit density and hopefully boost sequential transfer speeds up and over 200MB/s for laptop drives and 300MB/s for desktop drives.
Still no laptop hybrid drives with more than 8GB of flash memory, come on now. GTA 5 is 65GB in size!!
