Seagate Mechanical HDD with U.2 NVMe Interface Pictured, Signals the Decline of SAS 12G

I'm simply giving you a solution comparable to this - whatever hard drive you want (even 18tb) + 64gb of fast PCIe storage.

Not really comparable, because...

You'll have to install two drives and one program

...this.

and it will work better than any integrated cache drive available since those are limited to SATA3 speed

That is a matter of opinion.

oh yeah, large photo collections. because you would have 0.78125% (64gb cache, 8tb drive) of the most viewed photos cached in there for faster viewing?

Hybrids were good for using as an OS drive because they would cache the ~15gb worth of Windows stuff (or rather, the most accessed files in there) plus frequently used programs and files, but they aren't going to make the difference in photo backups


Have you heard about Intel Smart Response Technology? It lets you make a (64 gb max) SSD cache for your hdd. the remaining ssd space can be partitioned normally. AMD platforms have a similar tool. I guess it would help if you didn't want to meddle with two drives with different speeds and capacities.

the on-drive caches usually don't hold files, but the file tables
I found a super deep dive article focused on HBM memory and they went right into what's stored in the drive caches, DRAM cache and HBM cache by testing in a bajillion ways and they found they cache the 'index' for lack of a better word, rather than files

NVME w/ DRAM of course use them as a write buffer, as the one exception

Still makes sense and for the reason you just stated. Some people what a simple system with one drive. 8TB, 10TB or 12TB hybrid with a 32GB or 64GB SSD buffer? Hell yeah! That would make an excellent main drive!

In 2022? I guess for somebody willing to spend $300 on OS performance that’ll be slower and smaller than a $80 SSD and a sto:shrug:

Anything frequently accessed. Why would you NOT want that?

Of course it’s nice, but like I said — we’re talking one game, two blu-ray rips, a bunch of pictures… There’s hardly any benefit for storage when compared to cost, more points of failure, etc etc

Then I never liked hybrid drives, so uh do you

They’re talking about SSHDs, not drive cache

Yes.

You seem to be missing some context.

Your loss. They've been very useful.

Looking forward to a day when everything isn’t an argument to you

At least have fun with it; why not 1TB/8TB? I’d still never buy one, but at least it wouldn’t feel like tech from a decade ago.

You bring this upon yourself. When you stop attacking statements I make, I'll stop responding.

Let's be fair, modern HDD's, even non-SSHD's, perform well & truly beyond drives from a decade ago. Making that comparison isn't fair to modern drives and does no favors to your argument.

 

[claes]

I’m just making conjecture lol, thus the “shrug” and the “do you.” It’s not an argument, it’s indifference

This part is an argument, though: Having a 1TB/8TB SSHD is an advancement over your suggested 64GB/8TB. Sorry you misunderstood and you’re welcome

Yeah i didnt explain that part well - SSHD's are an oddity in that they try and do all of the above, which results in the cache often not having what's needed
primarily they cache the file tables as well to reduce the amount of seeking - knowing what to spin when, in advance helps a lot.

Then the read/write cache was a mystery as to how they balanced it, but a lot of what was discovered was more that recently written files stayed in there, moreso than reads.
Like your office documents and cached images were kept, but large files never were so games got little benefit


To be fair, I do like the hybrid drives. I'm fixing up a PC for an old fart who bought a 1TB QVO to torrent to with 4GB of ram in his PC and as you can imagine that went fantastically well, with a dozen ways to fix this setup and zero of them chosen - SSHD, a mech drive for D: , enough RAM for a cache, aaaanyyyythiiiiing
