Intel SSD Endurance

We have 2 postville-user´s in our forum with damaged sectors
I heard that the G2 only have 3.000 erase-cycles (G1 10.000). Is it true?

According to this it depends on process maturity. I’d guess it’s 5k for G2 drives based on that video link, but the minimum 5 year use warranty is the same for G1 or G2 drives. Maybe Intel have increased the spare block provision or maybe that it why you get trim on a G2 but not on a G1, which was made from mature 50nm nand @ 10K (afaik)

Does Intel hand out a minimum 5 year use warranty?
My product only states 36 months of warranty...

I seriously wonder how this all translates to normal use btw.
(Imagine a SSD running an OS that has several processes constantly reading and writing in the background, some internet usage writing small files and images all the time.. together with say... the G15 or G19 keyboard processes a lot of ppl use these here, those are pretty I/O instensive too).

Im using 2 x 160GB G2 in RAID0 (Windows/Games, 2 partitions).
I sincerely hope these drives are going to last me for some while to come...

From the product manual:

3.5.4 Minimum Useful Life
The drive will have a minimum of 5 years of useful life under typical workloads with up to 20GB of host writes per day.

If you are writing less on average that 20GB per day using desktop (as opposed to server) usage patterns you would have recourse based on that statement. How do they know what you are writing? SMART

In the in depth SSD article over at Lost Circuits the author explains that the smaller the nand process the lower the write count before the drive is worn out.

For example:

50nm mlc nand = ~10000 writes / cell

34nm mlc nand = ~4000 writes / cell

This expected lifespan can be increased by performing a secure erase and then using less than all of the available space for your partition(s) (increasing the size of the spare area).

Doesn't the Micron 34nm NAND have 30000 write cycles?

[F.E.A.R.]

WTF? No
30.000 only for very expensive Enterprice-MLCs.
I think, you can´t never find such SSDs in a normal shop.

Guys, did you check this link?

34nm MLC- 1.5k late 2008.
Process maturity increased MLC cycles within 6 months to 5K
30K is quoted for Q4 2009, but for enterprise.

I'd guess that G2's are using 5k cycle nand.

Edit. Corrected 30K

[F.E.A.R.]

Yes, and he says 3bit-MLC Enterprice with 30.000 cycles.
You can buy SLC und MLC for consumers, but no SLC and MLC for enterprice (maybe in special shops)

True, but just under the 3bit-MLC he is showing MLC @ 30K, although he states it is for enterprise, so I think you are a correct...it is not going to be found in non enterprise ssd's. (At least for a while)
