$550 for 4TB is insanity considering 1 year ago the SN850X 4TB was $230.

The latest greatest always has a price premium. You can still buy the SN850X at $580 for 8TB.

Even the current SN850X is already plenty fast. At this point all I care about is thermals and power consumption. If it offers improvement over that of current model that would be instant sold.

Hope so. I've been a big fan of Sandisk/WD drives for the past few years (SN850, SN850X and now SN8100), and if this is not resolved properly, I am walking away from them. Funny that they claim I returned SN7100, and that's probably one of few Sandisk/WD drives that I never purchased as I never ever

Crucial T700/T705, Corsair MP700 Pro(SE), MSI M570/580 and pretty much all gen 5 drives released in 2023 uses Phison E26 controller, which uses older 12nm process node and is thus lower performance and runs really hot (12W power max). In contrast, SMI SM2508, which is used on Crucial T710, Kingston

The SN850P is just a SN850X but with the additional heatsink for use with the PS5. The SN850X is in the process of being phased out. Its replacement is the PCIe Gen5 WD_BLACK SN8100. On Amazon, the PCIe Gen4 4TB SN850X is $560 while the 4TB SN8100 is $875. I paid $280 for a 4TB SN850X back in Novemb

sn8100 results before clean up to clone it, as you can see those all important qd1 4k reads are basically identical if not a bit better perhaps on the sn7100 as i only had a 3x512mb run screenshot in my docs before pulling the drive but its an insane result for the sn7100. dramless gen 4 clearing al

the graph to look at in the tom's hardware review: https://cdn.mos.cms.futurecdn.net/cQcY7nFsNJVHZoKo28VBwG.png actual sustained write testing. you see drops down to roughly 1 GB/s write speed, which is honestly disgusting for a pci-e 5 ssd. on a quick look and please correct me if i'm wrong here, t

I know.First gen Optane 900P drive advertised for Star Citizen: 550.000 IOPS (2017)Typical M.2 SSD from 2017: Samsung 960 Pro 440.000 IOPSLatest PCIe 5.0 SSD WD Black SN8100: 2.300.000 IOPS Also the access times got way better with M.2 drives. Now they are 3x faster and much closer to Xpoint Memory.

For the mainstream models like the SN3000, SN5000, and SN7100 WD/Sandisk use their own controller design and NAND from Kioxia/Sandisk. For the high-end SN8100 they use a Silicon Motion SM2508 controller. Describing WD as "mid generic" does not make sense, Samsung's vertical integration does not make
