SSD Write Endurance 25nm Vs 34nm

[Anvil]

Those are very nice charts Ao1

The SF compression chart is just like I figured it would be , quite interesting as the drive is being throttled as well.

80%, 2 reallocated sectors, 37.5TB. Switching to the new software.

Intel have posted a link to a very interesting white paper:

http://www.usenix.org/event/hotstora...pers/Mohan.pdf

It talks about the impact of the frequency of writes.

Longer recovery periods between writes can significantly boost endurance, allowing blocks to potentially undergo several millions of P/E cycles before reaching the endurance limit.

(Its not going to happen in our test)

We didn't agree on the random part, it's set to 1000ms per loop by default.

1000ms = 20-30MB? on the Intel's, is that something we can agree on or do we wan't more?

I've finally reached 30TB +

30.18TB Host writes
Media Wear out 82
Re-Allocations still at 4

@Ao1
Interesting link, will do some reading.

Here is some more info

P/E specs are based on the minimum.

Delta between most-worn and least-worn Flash blocks: 11
Approximate SSD life Remaining: 92%
Number of bytes written to SSD: 26,432 GB

Really nice to see Intel g3 with 25nm nand beat g2 with 34nm nand! !

Edit:

Another interesting snipet from the Intel forum:

"Read disturb refers to the property of Nand that the more a block of Nand is read, the more errors are introduced. A brief note about Read Disturb (and other various Nand properties) are discussed in this technical note from Micron:

Static data that is read frequently will eventually need to be refreshed or relocated before it reaches the Read Disturb limit because of this Read Disturb property."
