3D XPoint(of Intel Optane) is better than Z-NAND

Show all headers | View raw

Hello,


I will explain sequential writes and random writes, so that
you understand that Z-NAND that is Samsung's tweaked flash technology 
has limitations, and 3D XPoint(of Intel Optane) is better than Z-NAND:

When people talk about sequential vs random writes to a file, they're 
generally drawing a distinction between writing without intermediate 
seeks ("sequential"), vs. a pattern of seek-write-seek-write-seek-write, 
etc. ("random").


So now read the following to understand:

The random write speed rating on Intel's P4800X is only 9% slower than 
the random read speed, while the Samsung SZ985 will have a random write 
speed that is 77% slower than random reads. Samsung has not been able to 
overcome all of the limitations of flash memory, but they have produced 
some impressive improvements.
