A while back when I modernized my laptops and I got exposed to the sheer speed of gen 3 nvme and then seeing the new gen 4s and usb4 with its insane speed i thought seriously that ssds could actually replace HDD, the idea was that even though data retention was not on par with HDD they are soo much faster but that I could double or even triple up on data integrity, where HDDs take literally days to checksum, these sdds would in theory take mere hours. On top of that id get rid ofthe horrid AC wall adaptor, Yuk! Well that notion turned out to be a catastrophic failure.
- There are horrible inconsistencies of usb-c, 4, its a lottery and the enclosures are cheap junk, i know i tested four different brands of 40Gb/s enclosures. They are overpriced inconsistent junk.
- Once the cache on both gen 4 and 5 is used up the write speeds tank like the voltage of a LiMPO4 cell after it hits ~ 3.28V. Going from 3.3-3.6GB/S to 0.8-1.3GB/s.
- 4TB is nothing but a disgusting joke, 8TB is a joke. We are at TWENTY-FREAKING FOUR TEE BEES CMR HDD, absolute joke! These babies can do 260MB/s write speed all day long without any care.
-Nvme are plagued with stability issues like files not copying properly at those high speeds. Proven beyond a doubt over many months. I routinely get errors and on a few systems.
All these issues severely undermine ssds.
Then you just have to look at the growing evidence of data corruption, drives failing etc. not gonna spend that much on a 16TB, far too risky.
I only buy from brands like samsung, just too risky going a lesser known brand.
For what i do Gen5 is alot faster than Gen4, and good Gen 5 tops out at 4TB.
Then we have sata ssds, my samsung 8tbs can only do ~80-140MB/s sustained write speeds after cache is used up which is an embarrassment, HDDs are alot faster. These samsungs can do ~505MB/s read in my tasks but the write speeds are just unbearable. I do like 2.5" form factor as they are like credit cards and emit little heat, so i can put them anywhere in the case without worry.
Are HDDs perfect? no. under standard windows 10, my drives are constantly being accessed for no good reason other than to torment me, thats thanks to the wonderful people at Microsoft. Is there a way to stop this? Nope! of course not! why on earth would we want that to happen, what is wrong with you son??? your drives are getting a good workout and so is your ears, you should actually be very thankful of us you know. And dont bother complaining about how folders in usb HDDs frequently stay unresponsive for 8-10seconds, haha thats just normal, even though it never ever happened on windows Vista and 7, that annoying ridiculous lag is normal.
So yeah as sdds get cheaper our data gets more and more larger, its like Achilles, he never can catch the tortoise!
