WD is moving the product line from SATA3 towards NVMe for the Green SN350 series, so the new line supports PCI-Express3.0 (x4) connection over NVMe as opposed to SATA. The form factor is M.2 2280, an... Western Digital entry NVMe SSDs Now Become WD Green SN350 NVMe
Only 3 years of warranty and 80TBW for 960GB model for $99? Pointless. You can get Crucial P2 1TB with same transfers, 5 years of warranty and 300(!) TBW for $105. edit: Not 450, "only" 300, my mistake, wrong datasheet.
And I thought it was just a typo but nope, it's really only 80TBW -> https://documents.westerndigital.co...ssd/product-brief-wd-green-sn350-nvme-ssd.pdf
You have to copy 200GB a day for a year to reach that. Seems a bit whiney and laughable to be complaining about a Green Drive.
these SN350 units are pretty common in laptops, so we will see reliability data soon enough, and hopefully further cuts in prices, at "MSRP" these look as expensive as SN750 usual pricing
I don't think people have paid a lot of attention to their past TBW. 80TBW compared to 300TBW does seem bad, but, as you mention, you have to consistently move a crazy amount of data to hit that. Everyone has different uses, but here's my TBW for my most heavily used m2 drive. A 2TB m2 drive, only used for games with a 400 TBW limit (or) 400,000gb (for a 1TB drive, it would be rated at 200TBW). In 21 months it wrote 12,808 tb of data. So, 19.3gb/day on average. 7.1 TBW/year at this rate That's 56 years of expected drive life. Even at 80tbw, that would still be 11 years of life (for me). Maybe short, but still likely obsolete by then. And if we factor in that the TBW ratings ramp up with size, (a 2TB would be rated at 160TBW, not 80) it's 22 years. Usage will change and we will use more data over time, but I still think TBW is a metric we can mostly stop worrying about. I have yet to speak to anyone who ever actually hit the TBW on a drive, save for the earliest, tiniest SSDs.
