News DirectStorage 1.2 Adds Buffered IO Mode to Speed HDD Performance

With high performance storage, buffered I/O is slower than direct I/O. Funny that buffered I/O was added to what is supposed to be a performance interface. Granted, for HDD I/O buffering can smooth out performance during seek or rotational delays.
 
Sigh... Nothing like new old moldy technology... We had async I/O waaaaaay back in the 70's on our RSX-11 systems.... It was the only way to survive when your disk platters were roughly 18 inches in diameter with a seek time measured in what felt like hours! And don't get me started about those antique massive vacuum tape drives...
 
Intel had Optane, then they got rid of it. Stick a 16 or 32GB Optane M.2 drive on your machine with a HDD and Bam! It could copy stuff way faster. It was also cheap.

Really pissed me off when I upgraded my processor and suddenly found out my Optane didn't work anymore.

If you never used one think of this. Copying a 100+GB game from SSD to HDD. If your watching the copying screen it bounces percentage around while copying different files. Using the Optane made it always go at 100% full write speed of the HDD.
