CDan, yes, exactly. What's that little-boy mentality called? A p*ssing contest? To see whose goes further? And how many Greenstamps do bragging rights win? Enough for a coffeetable? Sheesh...
This is one of those "Just Because We Can Do It" engineering exercises and, frankly, from a Bragging Rights standpoint, this is an incredibly low bar to brag about jumping over. "Lookee - I can solder on a different mem chip!!"
Embed a 256Gb SSD onto the HDD circuit board and pop off, eh?
And the transfer rate STILL remains the same.
Get those engineers to improve THAT pathway and those memory controllers, ensure Read-Writes are reliable at those much higher rates, win the Standards Committee battle and THEN claim some real bragging rights.
