Samsung PM951 SSD - upgrade to a new SSD?

I have a 3 year old PM951 Samsung SSD, the 1TB model. I also have the latest-greatest PM981 SSD from Samsung, does it make sense to upgrade PM951 to something newer?

I cannot tell any difference between their speeds. PM951 is not that much faster than SATA SSDs, maybe twice as fast while PM981 is 6 or 7 times as fast as SATA SSD.

 

If you can keep the temps of PM981 down under heavy load then the performance in terms of R/W are almost double or triple of PM951.

 

I think you've already answered your question. Most users would never notice the difference between a SATA and NVMe SSD. Unless you're doing large file transfers or a ton of 4k video editing, I'd say keep the PM951.

 

I rarely do large file transfers or any 4K video editing. I only transfer a lot of data when I clone the disks with Macrium Reflect and it is does not matter how long it takes (but usually in about 30 minutes). and the process runs in the background.

Maybe I will wait for several more years until the 2TB SSDs drop to a reasonable price range and get it then.

I cannot tell any difference in real life between SATA SSDs and PCIe SSDs and especially between "slow" PCIe and faster PCIe.

 

For NVMe MR works great, backing or imaging is super fast. If you do OS imaging, work on huge datasets etc.. then NVMe upgrade might work for you.

 

I have come to realize what I really need is a 2TB external USB SSD. I have several SP Silicon drives and they are extremely slow being spinning rust.
