Hi everyone,
I've noticed that within the past 2 years SSD's have become significantly larger and cheaper. It wasn't long ago that a 120GB SSD was considered large, and was quite expensive. Now, they are more comparable to 512GB SSD's. in price anyway.
HDD's have been getting larger as well, and I believe 12TB capacities exist, but more affordable and realistic for home users is a 4TB, or maybe 6TB. A few years back, 2TB was considered large.
I've been thinking lately about when, and if, SSD's will overtake HDD's as the primary form of storage. SSD's are lighter and smaller. There's no moving parts either. I am not sure if they use less energy, are more reliable, or have a longer MTBF, however.
I imagine as long as there are hard drives, they will be cheaper $/GB than SSD, and therefore more attractive to consumers. I don't really know why they will remain cheaper, however. It seems price would be the only reason for them to remain relevant to home users (and I suppose large data centers as well). But what, hypothetically, is even keeping manufacturers from stacking a bunch of NAND memory into the dimensions of a 3.5" HDD. If they can fit 1TB into the tiny 2.5" drives, what's stopping them from putting all that memory into a 3.5" drive and getting a 4TB or higher SSD? I'm not sure why this hasn't been done yet, but I am sure there is some technical limitation I'm not aware of.
I feel like as a % of GB increase, SSD has grown more rapidly over the past few years. While HDD's have gained more GB, SSD has gained a larger increase/$.
Most of what I've read on the internet, on forums and such, posters argue that SSD won't overtake HDD for a LOOONG time. I haven't seen many explain why though. I am curious to the physical limitations on how dense HDD platters can get. Are we reaching their peak density? I've noticed some manufacturers are using helium now. Can the SSD theoretically be made denser than the HDD? This is probably a bad analogy, but HDD seems more "analog", while ssd seems more "digital" to me.
Can someone explain this for me?
Thank you!
