Micron Ships World's First 232-Layer NAND, Extends Technology Leadership

[bug]

The NAND will come, and will be good, but not positive that we will see cheaper drives - considering how prices are rising for everything.

Think about it this way: even if the price goes up, it will go up less that it would have in the absence of 232* layers NAND.

*232, is that a nod to the serial protocol?

I hope random performance is increased a fair bit with this tech.

It will increase in cases when access can be parallelised/queued, but not much at QD1. TPU's tests put a lot of stress on the QD1 results (QD1: 75%, QD2: 20%, QD4: 5%), I think too much but frankly I don't know.

I think that's too low. Anyhow, on a home PC you're highly unlikely to hit anything above QD4. Even that, you'll hit very rarely.

There is a catch, however. QD1 4k random reads are what limits the performance of an SSD in practice, as most of the reads are 4k random on a home PC. But those don't always happen in bursts. Or at least not in large enough bursts. Thus, all SSDs appear identical under normal usage.

Since I'm not running a server or doing scientific computing I have no use for more than SATA SSD sequential speed. All this speed means nothing until applications and games start to make use of DirectStorage.

What DirectStorage does is move the burden of decompression from the CPU to the GPU. It should benefit systems with slow and fast SSDs alike, actually slower systems should see more speedup.

I've always wondered if Windows is any intelligent when moving or copying a large number of small files. Queueing (also above queue depth of 4) would be very, very benefical in this case.
