Not like PCIe NVMe storage drives went away. If you don't like M.2, you can opt for one of those. Though in reality there is little difference the same flash chips and the same controllers just in a different form factor.
That single standard has let them price compete themselves all the way to current pricing. 3.5 cents per GB.
My first 256GB SATA SSD was $200, that is 78 cents per GB.
My issue isn't with the PCIe connection or the NVMe protocol.
I'm fine with that.
It's the fact that MoBo makers want to shove the M.2 Connector onto DeskTop MoBo's when the classic SATA/SAS/U.2/U.3 connector is FAR & AWAY superior for DeskTop usage.
M.2 Connector is perfectly fine for "LapTop" uses when you're not expected to ever realistically take out the Storage Drive execpt for servicing.
The M.2 Connector was designed for a FAR lower Mating Cycle (Insert & Removal, no Pervy Jokes Plz) life-span rating than the SATA/SAS/U.2/U.3 connectors.
M.2_ = ___ 50 Cycles
SATA = 10,000 Cycles
Literally, orders of magnitude more resiliant to day to day handling within the DeskTop/Server Environment usage.
We need the 1.8" HDD form factor to come back and replace M.2 for DeskTop usage w/ U.2 or U.3 connectors.
Durability is key and the 1.8" HDD form factor with 5 mm thickness is perfect, it offers more PCB Real Estate, built in Heat Sink with the Aluminium Shell, a ruggidized boy that everybody can handle.
And in a Standard Sized Bicycle Poker Card Box, you can easily fit 5x 1.8" 5mm thick SSD's with room for a protective outter sleeve and connector protection.
So having a more rugged form factor is better for many people and having it be "Small Enough", yet rugged enough would be better for most people.
And we could easily be promoting BackPlanes that allow Easy Hot-Swap for people using 1.8" SSD Drives.
