Sandisk talks UltraQLC-based 1PB (1 petabyte) solid-state drives and 3D DRAM during its investor day.

Fun fact: At the max theoretical speed of PCIe 5.0 x4, it would take over 17 hours to transfer the entire drive contents of a 1 PB SSD!

That's in the realm of what it takes to transfer the contents a much smaller HDD of maybe about 10 TB.

Of course, by the time this is a commercial reality, it might well be using PCIe 6.0. Even then, just cut that number in half - that's still quite a while!

1 PD? I need 12 TB M.2 PCIe 5 SSDs and we all need the 8TB models to drop to 300 bucks.

I don't (and will not) use RAID or any form of stack or array. I use a single data 8TB SSD for my image data and back up to other single and separate 8TB SSDs.

I'm a photographer and my image files are at 7 TB now, thus getting close to the 8TB ceiling.

I want all my image files on one SSD and 3 single and separate backups. So, I need four 12 or 16 TB M.2 SSDs please. This 8TB barrier is starting to annoy me.

This is a datacenter SSD, obviously. It will be eye-wateringly expensive. It will use the same NAND chips as consumer SSDs, just to give you an idea of how many of them it's going to need.

You can get datacenter SSDs that big and larger (up to 60 TB, at least), but you're not going to like how much they cost. They also tend to burn a fair bit more power than consumer SSDs, not to mention coming in larger form factors.

Right now, HDDs are your best option, if you don't want to just sit on your hands and wait for the next bump in SSD capacity. I'm sure that's not what you want to hear, but not long ago they were the only option for such storage needs.

Personally, I don't trust my most valuable data to SSDs. You can put a HDD in a drawer for 5 years and still read the contents. Not so, with the type of QLC SSDs you're talking about.

BTW, the 3D DRAM comments are interesting. I had no idea Sandisk was even in the DRAM game, but I guess it makes sense as a lateral move for them, since they have so much experience with 3D NAND.

3D DRAM, which is not about to happen quite yet, according to Sandisk (the roadmap target lacks a date).

Samsung might commercialize it in the early 2030s, after VCT DRAM.

Cash here, thats my Musk and Trump OnlyFans content backed up.

You do backups to SSDS?!?

Do you have them plugged into a secondary system to keep the flash refreshed? Otherwise, 6 months later you have a good chance of those being bricks as far as backups are concerned.

A year at best is how long that data will last on a SSD that is not plugged it.

I dont trust my data either when it comes to SSD. On a working system its fine since i tend to offload my data on an attached HDD. I back up that data onto an external HDD as well. And then once more just in case. SO i have 4 copies of the data. Nightmare to deal with.

SSD to onboard HDD and i copy to the external at the same time. Then once in a while i take out the other HDD to top it up.

I still have CD-ROMS that i burned 20 years ago that read and they have organic dyes that degrade but they are still going. Back in the early 2000\s the idea was 10 years for the life of a burned CD-ROM....here i am 20 years later. But all that info is on the HDD now. Stacks and stacks of CD i had to transfer. What a PITA

I just archive everything to my NAS, and have two external hdds that I rotate out on a weekly basis. Not bulletproof, but enough for what I keep.
