Price/density is still important for storage, but I can't see myself owning such a big HDD ever: imagine it starts to fail and you try to backup all that at low speeds (don't ask me how I know). Ya I know, I should have at least 3 copies ready in case of failure. Fortunately I don't own that much data or I'd be sunk on HDDs. My current Storage medium has 6Tb and so far works wonderfully for my needs, I wanted to get another one but prices ain't moving down: only up! Bleh.

The nice thing about HDDs is (generally speaking) the higher the density, the faster the sequential reads. You can get close to 300MB/s on a 20TB drive, which is slow compared to an SSD but you could in theory backup the whole drive in about 2 hours, if I did my math right. I'd say these are good drive for archiving but not so much for actual use. Also... I'm surprised how cheap some of these are. I guess with demand for HDDs plummeting, Seagate doesn't have to pay as much for neodymium or helium.

You did your math wrong, it's about 19 hours, not 2. Actually, it's even slower than that, as the "300MB/s" is only in the fastest outer tracks, the speed drops to about 1/3 on the inner tracks when the drive is almost full (not linearly). Then, the speed is not maintained constantly even if you have just large files, as the drive permanently needs to recalibrate head positioning, to make sure it's writing or reading at the correct location. Distances between tracks are incredibly small, and extreme precision is needed to point the head correctly. So in reality, it takes some 30 hours to fill or empty a 20TB drive (Took about 20-24 to fill my 14TB's at full throttle)

Nah, that's not how you do this... if you wait to backup until "it starts to fail", it's already too late. Instead, have some kind of redundancy system (eg. RAID) or parity drives, and don't worry about "drives failing". Use them until they do fail, and when they fail, just replace and rebuild the array.

I know I should have a backup and not wait for the drive to fail, but I'm poor to have multiple backups just laying around: I buy what I need today. I'm not familiarised with arrays, and they're probably too expensive for me anyway. They look cool on big youtubers channels but for the average Joe is not easy to swallow the cost.

I'm an average Joe. Actually, a rather poor average Joe, at least compared to westerners. Check Snapraid software (it's free). You don't need to buy 5 new drives at once to make a redundant array. Keep those you have, add one more, setup parity (no need to reformat anything!), and you're done ! Keep adding drives as needed, as well as removing old/small ones as needed, just rebuild the parity.

I just have an external WD 6Tb drive, how do I do that? PS: Just noticed you have an RX6800XT, sorry but you're not poor.

My previous GPU was a GTX 1080, and I got the 6800XT in late 2022. Imagine saving money for 5 years waiting for the GPU prices to drop... 🙄 But we're going offtopic.

If that's all the storage you need, then, well, we're definitely in the wrong topic.

I used to change GPU every 2 years, almost 20 years ago. Now I stick with the same GPU for 5 or more years BECAUSE OF ABSURD PRICING (and very low performance increments). So by your logic a GPU could cost as much as a car, you just save for 10 or 15 years to buy it or get a financial credit! *facepalm* We need to be reasonable here: there's not thousands of (insert your currency here) worth of components on any card, ever. Quality has even gone down, stuff used to last for +10 years and we're lucky it last over 2 now. The general public has no economic/financial sense and "just buys it": "this onion costs 100€, I'll buy it cuz I wanna do a stew with it". Everyone has different storage needs, I would need more if I could afford it. But again, everyone values their money differently so I chose to get movies compressed with x265 instead of x264 and delete old stuff I don't need, for example. Managing my storage instead of letting things pile up unused and unattended for has saved me money. For example: I shoot movies in 4K of bands playing live and upload to youtube. After some time, I delete the old files I don't need so it doesn't take all the space.

Hi! I am new here, so please be nice. I want to know if the new HAMR 30TB HDD will have the MACH.2 technology. Does anyone know? Thanks.

Just to note, these are Hard Drives with a write cycle limit, the heating of the platter can only be done so many times before warp happens.

Can you please be more specific? I don't understand you.
