Patriot Viper has a question mark.
MydigitalSSD BPX Pro is listed as DDR3L or DDR4 , same goes for the PNY XLR8 CS3030.
Seagate Firecuda isn't listed as using a Phison E12 , however this suggests these sites say it is a rebrand: https://aphnetworks.com/reviews/seag...cuda-510-1tb/2
Looking at the list for PCIE 3.0x 4 it seems there's only Samsung in-house, Phison, Silicon Motion, Marvell (only on Plextor's drives). There's a few one off such as Toshiba's TC58NCP090GSB
on the XG6 and WD/Sandisk's in-house controller on WD Black SN750. Adata also has a few older drives based on Realtek controllers.
The Sabrent Rocket you listed as expensive is using Phison E16 and is PCIE 4.0 , $110 on Amazon for 1TB currently https://www.amazon.com/Sabrent-Rocke.../dp/B07LGF54XR
As if it matters, they probably just put what they have on the line that day from supplier. TG and Viper have same but a little different PCB and is not engineering sample design as are SP and Corsair.
FireCuda 510 is listed as Controller Phison PS5012-E12, 8 channels, Memory modules 3D-NAND TLC, Toshiba/WD, 64 Layer (BiCS3) and the very same common specs even in their own datasheet as all other E12+Toshiba drives, photos show same PCB design.
Photos and review here:
It's nothing more than an E12+Toshiba same as all other. All they did was pay Phison to print Seagate on the controller. And bang, +100 EUR in price to the customer! That's how you make money at Seagate.
Same RAM too.
I've listed SB-ROCKET-1TB which is PCIe3.0x4 same as your link is. Not SB-ROCKET-NVMe4-1TB which is PCIe4.0x4.
Silicon Power from the Anandtech photo, I don't think I took photo of mine without heatsink, all the other photos of Corsair, Seagate have the same RAM too:
H5AN4G8NBJR UHC 814V
DDR4-2400 17-17-17, 4Gb / 512Mx8, 78 ball FBGA, you can read the other timings out of specs.
512MB DDR4-2400 per side on 1TB drive.
Viper VPN100 1TB is also double sided. Of course there are differences in single/double side and RAM available for each capacity model.
If one wanted to for some business purpose they could probably look up the factory making all these drives and order a batch with their own sticker on it. That's how it's done these days with many things, 1 source many stickers with different names.
SATA old slow interface and same hardware as other SSDs on M.2/PCIe. SATA SSD is dead until they start offering large capacities at low prices, that's where they have the space to fit more chips unlike M.2 drives that can only fit so much into the small form factor.
With new boards having even 3x M.2 and direct connections to CPU instead of chipset, SATA unable/unwilling to drop prices lower to compete on value, SATA SSDs have had it, nearly no one should be buying them anymore.
I know it can't get any faster, but even cost wise it seems they reached same minimum right now as M.2/PCIe drives, in the end M.2 is even cheaper to manufacture as there are no enclosures to make and pay for, less connectors, etc. even hardware cost wise M.2 is cheaper to make. Hell they probably spit the drives in mass and then cut them to individual pieces. Where as with SATA drives, some poor humans have to assemble it or they have another machines putting it all together. M.2 cheaper to make than SATA drives.
Those QLC drives are hardly worth anything right now in any form factor.
