I hope the M3P lives long enough to throw off the chart scale as well.

B.A.T.
Am I imagining things, or did the M4 go from 33 erase fail and 0 program fail to 33 erase and 26 program failures like 4 days ago? Hmm. I wonder if that just means it just had to try a couple times to erase or program, but no blocks were taken out of service.
You have good eyes. I missed that one. It changed to 26 between 29th and 30th of may.
Just for amusement (and with no expense spared) a 4 GB unbranded USB drive. No SMART info. :D
Assuming 1,000 P/E cycles @ 2.5 MB/s it could in theory last 19 days.

A01,
Do you happen to know what manner of flash is up in there? I'm sure when it dies you can pry it open. All things considered, 2.5 Mbs isn't terrible. It's not much worse than the 32GB PS 100 Phison I tried.

(@ Christopher. Don’t know what NAND it is using, as it’s a sealed unit. Will take it apart to find out when it dies).

I have a spare 4GB ADATA C906 USB2 stick, NAND is Micron 29F32G08CBACA, 10th 2011 manufactured.. I guess it's 25nm 3K P/E asynchronous..

Stupid question perhaps but here goes anyway;
Looking at the charts in post 1 can I assume that if a given 60Gig drive reaches MWI in xTB written then the `120Gig version of the same drive should hit MWI in 2xTB and the 240 in 4xTB etc?
This is mostly true for most drives. Most drives use average PE cycle count to determine MWI 1, meaning a drive with flash rated for 5K PE cycles will consume 1 percent of MWI every 50 PE cycles. The 64GB Turbo I ran used 1 PE cycle for every 56GB written, so for every 2800 GiB written in the test the drive would reduce MWI by 1.
Some drives, like the M3P and the Octane, rely on reallocations to determine MWI, meaning MWI will never decrease until there is a block failure.
amazing the Samsung 830 hasn't slowed 1 bit.

kaktus your usb flash pen is not aligned.
Generic USB Drive – 4 GB

So after 7 days I put the drives back in the endurance rig. Both drives' average speed is down by 5MB/s, and current speeds never quite get as high. Even with all power saving technologies disabled and on the same RST version, it's just not as fast. Almost, but not quite.
same MB or different?
