Stringtheory

I'm setting up some some new systems (for neural net research), and purchased Corsair 2TB MP600 m.2 for installing the operating systems. They are not recognized. So I replaced them with Samsung m.2, and they came up immediately. Tested with a couple different Gigabyte motherboards running Win7 and Win10. Any ideas about inherent differences between Corsair vs Samsung that could cause this? NOTE: Corsair's website is buggy as well, so the question could not be posted there. Needless to say, I'll be going with Samsung from here on, but I'm stuck with some MP600's that I'd like to put to use if possible.

Very helpful, thanks! I've had some m.2 NVMe drives that literally got too hot to touch. I thought there may be more to the dissipation figures than the numbers indicated, since published idle figures are very low, and even 5 or 6 watts seems miniscule compared to CPU. But perhaps the misleading factor is the area and heatsinking of the CPU. I guess even a 5 watt lightbulb would get too hot to touch. I haven't seen much difference in heat dissipation specs for 1TB vs 2TB m.2's. So given the ratios, I'll go with three 2TB m.2 drives, and figure out how to turn off the GPU when it's not needed (presuming that I can do this under Linux).

I'm trying to maximize battery life in a laptop with an i9-9880h and 2080 Max-Q. The CPU and GPU will be the main sources of battery drain, but I'm trying to assess impact of adding more m.2 NVMe and SATA drives. If figures that their contribution to power drain will be relatively small, but there are a lot of specs in play, including power consumption at idle, which is often difficult to find. The laptop has two m.2 slots that will work for NVMe or SATA, and a third slot that is SATA only. I believe 2TB m.2 SATA drives will consume only half the power of an m.2 NVMe, perhaps averaging 3W to 6W respectively. But it would be nice to get a rough idea of their overall effect on battery life. The 3W and 6W figures do seem low. I've seen some Samsung NVMe's that get too hot to touch.

The Corsair Force MP510 and Samsung EVO Plus seem to be very close as far as published specs, with the Corsair having an edge in endurance and in price. But there must be more to it. Has anyone come across more in-depth comparisons that would tip the scales one way or the other?

TMI? I'm not sure how info about the application relates, but hopefully that was enough background. As far as I know, the Samsung EVO Plus, Corsair MP510, and WD Black SN750 are the leaders at the moment for non-enterprise NVMe. Basically just looking for opinions/thoughts on advantages in each of the three NVMe models, or on any others that may be close.

PS: I don't know if temperatures come into play either. I've heard reports of some of the drives getting very hot under continual use, but I don't have much of a gauge for duty cycle yet. The previous Samsung 983 DCT got too hot to touch without even running anything, which was surprising.

The EVO Plus is the one in the spotlight at the moment, but I was asking about contenders. The main two that I keep seeing are WD Black (2019 model) and Corsair. Application is neural network development, mostly. Linux, C++, Python. Lots of number-crunching. The machine has 64GB RAM, a couple 1080ti's and lots of storage. CPU has 28 lanes, so allocation is OK, given that the second GPU can be run with 8 lanes without losing much. That leaves 4 lanes for the NVMe. I'm just trying to get the best speed and endurance. May help in caching some ops, and in swap (if it comes into play), so I was also weighing 1TB vs 2TB. (The EVO Plus 2TB is not available yet) I was originally hoping to use an enterprise class Samsung 983 DCT, which has power loss protection, but I've had no fun with it. (Not recognized as a boot device by BIOS, etc) I think that's about it...

I've had some trouble with my current NVMe (Samsung 983 DCT, an enterprise 1TB M.2). Considering trying 'consumer' NVMe such as Samsung's 970 EVO Plus or equivalent. The two main contenders seem to be WD Black SN750 and Corsair MP510. I haven't found much in the way of critical comparisons. Thought I'd check to see if anyone had opinions about these.

Thought I'd check back with the results: I bought two LSI 9207-8i boards. Installed under Windows 7 for now (which I prefer for development machines). I didn't reflash to IT-mode. In fact, I don't know much about that, so I just went with the stock firmware. Win7 did need the drivers to be installed. Win10 may not...I don't know yet. In any case, it seems to be running very well! On one of the systems, I trust the LSI controller more than the built-in motherboard SATA controller. I was originally considering one of the newer Syba cards when I spotted the LSI. I'm glad I went this path. Thanks to those who took the time to advise!

I'm looking for reliable 8-port SATA 6gb cards, pref PCIe v3, x8. Don't need RAID, so the 9207-8i seems like it would be a logical choice. But I haven't been able to verify whether it will run under Windows 10 or not. Do the appropriate drivers exist?
