To bump the NVMe SSD to M2 2280 2TB PCIe NVMe SSD Class 40 adds $851.80 to the price. Too much for me.
Highway robbery.
Absolutely correct; insane pricing.
I don't know about this "class" thing. Apparently it is a Dell invention.
Yeah, IOPS and/or MB/s reads & writes are what matters.
Here's a random amazon.ca 2T NVMe drive. Good brand, good price. <https://www.amazon.ca/Crucial-T700-Gen5-NVMe-CT2000T700SSD3/dp/ B0C3K7MTSY> It is $289.99.
That is a shockingly good storage device - it's PCIe Gen5 with 12,400 MB/s speeds: more than twice the theoretical maximum of a SATA port. A good choice if one has PCIe5 on board.
There are probably cheaper and better ones. For example, this one is cheaper at $163.99: <https://www.amazon.ca/dp/B0C3VCD5Z8/ ref=sspa_dk_detail_1>
Decent performance at R/W Speed up to 7400/7000 MB/s. I didn't see mention of any on-board DRAM cache, not sure it's necessary. In my online shopping, the WD Black sn850x is looking very promising: https://www.canadacomputers.com/en/desktop-laptop-internal-ssds/226016/ wd-black-sn850x-1tb-pcie-gen4-nvme-m-2-ssd-wds100t2x0e.html Comparing that WD Black to Samsung 990 Pro:
In any event, the WD Black SN850X and Samsung 990 PRO are two of the fastest Gen4 SSDs to date. And it’s quite likely that they will keep their top spots indefinitely – not just because manufacturers and users move to Gen5 SSDs, but also because they largely max out the Gen4 interface.
