SM951 as already stated is not really a consumer product and as such.
- Warranty is only 2 years (and not 3 as stated above). Also resides with the re-seller and NOT Samsung. As these drives were never really intended to be sold to retail customers.
- No support from Samsung in Magician. Or any other monitoring software come to that. So nothing can read the SMART data, secure Erase it, or update the firmware. Where the Samsung 950 pro is fully supported in Magician.
- Thermal throttling (as long as your case is well cooled) is really a non issue on these drives for the average user. Only really experienced in the sort of sustained heavy workloads that you can find in some synthetic benchmarks. All the reputable sites state this (Anandtech, Toms Hardware etc.). Quote from Anandtech:
"To sum things up, there is no need to worry about thermal throttling under typical client workloads. There won't be any notable performance loss unless you subject the drive under an intensive sustained workload which may be relevant to some professional users (e.g. high-end video editing), but not for the typical enthusiast and power user...."
- To get full performance from them ... Make sure you are running a motherboard that fully supports PCIe 3.0 and the latest M2 socket.
Nothing wrong with these drives (I do in fact have one myself). But if I was buying now, I would go for the Samsung 950 pro. And unless money is a consideration, this would be my recommendation to anyone at the moment.
Only really posted the above in case anyone else is reading this and is interested. As OP has already purchased an SM951. And as usual it's really up to the individual as to what they do etc.
I'm sure you will have no problems with your SM951. Great little drives but still hard to recommend against a decent SATA based SSD if considering value-for-money against performance etc.
PS. Native Windows 10 NVMe driver seems to work fine with these drives (that's what I run with). You can install Samsung's NVMe driver that is for the 950 pro (available on their WEB site) and that appears to work as well. Though I saw no real difference when I tried it, so reverted back to the Windows driver. If you do run with the Samsung 950 NVMe driver, the latest version of HWiNFO64 will give you some basic drive information...
I have a sneaky feeling that Samsung have actually disabled SMART functionality in the firmware in these drives. As I have read of a couple of instances (when they were running earlier firmware) of a couple of folks bricking their drives when trying to Secure Erase it. Also worth noting that he latest version of Parted Magic also can't Secure Erase these drives. I had a long (and at times acrimonious) discussion with a couple of the PM boyz on their forum about this.
