Instead of the SMR crap I would rather have a 5.25" HDD with CMR.I wonder what capacity would be possible with a 5.25" CMR hdd .Maybe 40 tb?
>>107121881It'd be way slower due to physics.Larger disc to spin and longer seek times.It'd be louder, too.

>>107121910The platter doesn't need to fully utilize the 5.25" diameter.It could just be larger than 3.25" for more space, but not large enough to diminish the performance.Also they could fit more platters since the 5.25" slot is taller.On the side of the device, they could add a M.2. slot where you plug a SSD that functions as a cache. There is a fuckton of space to do it.
the larger the platters the more vibrations become an issuespeed is only an issue because you would have to spin the platters slower, if you spun at the same speed it would actually be faster sequentially for most of the disk, but you still have the issue of seek times from longer maximum head seek distance
>>107121928had one big boy like this, sounded like a jet engine turning on
>>107121928I had one of these, a whopping 4.3GB. Friends told me I'd never be able to fill it
>>107121881It's a huge risk.The cost of R&D is one, but more importantly no one is making a server/jbod chassis for 5.25" drives, so you'd first have to convince everyone to start making them in the first place, then convince the HDD end users that switching from 3.5" to 5.25" is worth the hassle.
