With or without DRAM cache?
Host Memory Buffer is mentioned in the news so without DRAM.

But PCIe 4 ... what's the point? Could it be that transfers consume less energy per bit, possibly enough that it matters in notebooks?
 
dram-less gen 4....

3.6/2.8 R/W....

mega-super-duper y/A/w/N....... :)
 
People who think DRAM-less inhiritely means slow \ cache-limited need to check out drives like the SN770.
You can be DRAM-less and blazing fast with respectable workflow. Its up to others to catch up to "how".

DRAM cache is overrated, and not worth the huge markup in price.
 
BOM of SSDs with DRAM is not too much. Usually in use are small old memory chips like 2*1GB DDR2/3 for cents. In latest models have also DDR4 2666 or something and in flaghip size models has 2*4GB this is maximum DRAM cach which I see ever. I think price of buffer average is less than 10% of production costs.

Try copying a fairly large file and see what happens... :cool:

I know, I know... large files. How often does an average user move around large files though? Most people buy these for gaming. All I'm saying is, DRAM-less drives are perfectly fine, they are sometimes even better just look at the SN770

You don't get it. :) An average user is moving very big files, every time you install a big game, which usually has a lot of big package files. Or when you stream, etc.
You don't want your nVME SSD to be as fast as an SATA one, now, don't you?
 
Is it possible to exaggerate the resource requirements needed for streaming? I still think that the task is not so very demanding, except for some retro computers with old slow 4900rpm HDD or really low budget SATA SSD from 2012?
 
"The UD85 is all about value: it's available in large storage capacities up to 2 TB with an affordable price tag."

Give me a 4TB or 6TB or 8TB with an affordable price tag please.
