Is there a market for new 3.5 inch SSD with the tech we have now?

Recommended Posts

Posted · Original PosterOP

I don't know if this has been answered yet so I figured I'd give it a shot. 


I'm building a custom NAS for my home and I was selecting new drives for the system. Naturally I wanted capacity over speed so I looked for Ironwolf Pros. I planned to use a Samesung SSD for a cache anyway so that was all good.


That got me thinking, since we can fit up to 2TB into a 2.5 SSD drive, why isn't there a modern 3.5 SSD option for larger capacities? Surely Seagate, Samsung, or even Intel must have come up with the idea. 


I know that 3.5 versions exist, mostly thanks to flash storage being more expensive and larger back then, but why have we stopped at 2.5 and not getting better for bigger physical sizes?


Imagine the possibilities, data bases would then have a more reliable storage unit, you wouldn't need as much of a cache for local systems due to near instant response, data loss due to dropping or moving a drive would be nonexistent, drive vibrations would never be a issue again(though the drive itself might need a fan but still wouldn't hurt surrounding drives), the list goes on.


I know that SSDs are going towards PCIe and NvME for connectivity, but there is still a place for mass SATA storage. 


So what's the problem?

Someone could just shove 2.5-3, 2.5" SSD hardware into a 3.5" space, but I think most enterprise hardware is moving to only 2.5" drive bays anyways.

I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...



What is your budget/country for your new PC?


what monitor resolution/refresh rate?


What games or other software do you need to run?

You can fit more than 2TB in the 2.5" form factor. Samsung makes an almost 16TB drive in 2.5". 

Seagate made a 60TB 3.5" drive. IIRC, it never went into production...meaning there wasn't enough interest in it.

There just isn't really a market for 3.5" SSDs.

In short, no. I mean in theory you could load up a 3.5" enclosure with a ton of controller, DRAM cache, and NAND chips, but it would be excessive and unnecessary.

Yeah there were some, I guess no interest for it or more benefit opposed to use more smaller ones for same totale physical space and or capacity. Probably also price for sure. 

With PCIe advances and all it wil be interesting to see more and more connections for NVMe SSDs and probably less SATA too.
