Been finding some good deals on 2.5 disks lately, but have never bought one before. Have a couple of 3.5 disks on the other hand in my Unraid server. Wondering how much it matters wether I get a 2.5 or not? What form factor do you prefer/usually go for?
I think 3.5" are usually priced better per tb than 2.5" drives and performance is usually better too. So unless you feel like burning money for an inferior solution, are have some space constraints that doesn’t allow 3.5" drives, I wouldn’t go with 2.5" drives. They’re more energy efficient though, but you’d need a fuckton of drives for that to make a worthwhile difference in your power bill.
The key here is “better performance at similar price points”. There are absolutely amazing 2.5 drives made for server applications, but they cost so much money you’re better off getting SSD these days.
Speaking of which, you should consider SSD.
Absolutely no shot I can afford 40 TB of SSDs for my NAS
Man, I remember when Zip Disks were a big deal and a GB was a lot of storage.
One of my clients referred to Zip disks a few days ago. That really sent me back. Only my rich friends had Jaz drives, whereas the rest of us were still using Zip disks and optical media. Those early USB thumb drives at USB 1.0 speeds were also painfully slow.
My portable storage journey progressed from 5.25” floppy disks, 3.5” diskettes, Zip disk, CD-R/RW, DVD-R/RW, 2.5”/3.5” external HDDs and now portable NVME SSDs.
I remember learning that 3.5" disks were still called “floppy” disks, despite being rigid plastic. My teacher took apart a disk and showed us how the inside was a film, but all that did was encourage us to take apart the disks and make desk toys out of the springs.
That’s fair.
Depending upon your storage setup, may be able to make use of an SSD cache drive for a larger rotational drive array, though.
Ssd for boot but not cost effective for nas. Nor do I trust their longevity.
SSD longevity seems to be better than HDDs overall. The limiting factor is how many write cycles the SSD can handle, but in most cases the write endurance is so high that it’s unreachable by most home/NAS systems.
SSDs are however really bad for cold storage, as they will lose the charge stored in their cells if left unpowered too long. When the SSD is powered it will automatically refresh the cells in the background to ensure they don’t lose their charge.
Thanks, yeah i’ll go with 3.5" ones then, only reason i considered it was because of some really good deals. But I’d rather stick with having a uniform set of drives. Thanks for your input!
