SSDs vs NVMEs

Hi everyone! Hope you're all having a nice life! :)

Good bye SSDs? Or you think is still worth the money investing in SSDs? Even more so given the fact that the difference in price isn't that much, at least from what I've seen
this SAMSUNG 870 EVO 1TB 2.5 Inch SATA III Internal SSD is $150

https://www.amazon.com/Samsung-970-...=1&keywords=nvme+drives&qid=1616070325&sr=8-1

This Samsung (MZ-V7E1T0BW) 970 EVO SSD 1TB - M.2 NVMe Interface Internal Solid State is even cheaper $143

I'm just asking because I don't really know the difference and would like to hear/read from someone who's actually used both. I'd like to get my hands of some SDD - or NMVE? - sometime soon in the near future when this pandemic thing ends once and for all. I'm not a developer whatsoever and certainly don't compile software but still, the improvement is always welcome. :)

Hardware isn't my thing but you are confusing two things, the Samsung 870 EVO 1TB and Samsung 970 EVO 1TB are both ssd's. The difference between them is the connector, the first one uses Sata and the latter one uses M.2. The one with the Sata connector uses the SATA-600 interface for data transfer which is also used by normal hard drives. The latter one uses the PCI Express 3.0 x4 interface for data transfer which allows you to get higher read and write speeds than ssd's using the Sata connector.

Samsung 870 EVO 1TB(ssd sata): read: 560MB/s, write: 530MB/s
Samsung 970 EVO 1TB(ssd m2): read: 3.400MB/s, write: 2.500MB/s

I have a normal ssd in my work laptop and I had an M.2 ssd in my previous laptop and didn't have any problems with that one overheating either or failures. In my current desktop I have a Samsung 970 Evo Plus 2TB and haven't had any problems with over heating or failures either. Maybe it depends on the laptop and how well the airflow is and what type of cooling mechanism they use on the nvme ssd.

Nvme ssd's do have a Total Bytes Written(TBW) limit, for the Samsung 970 EVO 1TB that is 1.2PB. I have asked different computer hardware stores and they say in reality you will most likely never run into this limit. To give you an idea, I have been keeping track of the amount I have downloaded from usenet and I have moved the history across several different systems and my total amount downloaded currently is at 43TB now, so there is no way you are going to run into this limit with a normal workstation.

Thanks for the clarifying. I did notice that but wasn't sure what it meant, like I said, I don't really know much about this topic. Back in the day when SSDs came out, I had the opportunity to buy 1 or even 2 but didn't do it because it was still relatively new and wasn't sure what to buy, i.e. which brand. Now, my economics are a bit harder and computers are not a priority for me, I mean, I do want to upgrade my rig, or better yet to build a new one, but there are other stuff which are at the top of my priority list, however, I hope I can some time soon enough in the near future.

Frankly? In the past decade, I buy new computers out of habit. The truth is that they're fast enough for me already. My only bottleneck now is bandwidth and my download speeds are acceptable and my upload speeds are a product of my living very remotely (it's a feat that I even get DSL - and it was an expensive feat).

@Tolkem Thanks! Will have a read as well, I hope I explained it correctly for the most part.
