The write speed has dropped to around 1 MiB/s on the G1. I think it's not long until it is finished. ASU is still slow and unresponsive but the drive still works and read speed is good.

The G1 has stabilized at 1 MiB/s but still hangs in there. Just have to wait and see what happens this week. Another development. The m4 has reportet its first raw read error rate. The last time it got these at 600TiB but still no reallocated sectors. :D
Hi guys :)
I've been out of town for a few weeks, my drives are OK but have been idle for some time, I'll get them restarted tomorrow.
I'll catch up the next few days.
(hopefully most drives are still running)

At 08:42 this morning the G1 pulled his last breath and went away silently. It just couldn't take any more after 10.5 months of torture. I tried every trick in the book but I can't get it to connect again.
R.I.P Intel X25-M G1 80GB :(
My plans now is to update the firmware of my Mtron and Vertex 1 and throw them back in the blender :D
That G1 went out like a boss. 10.5 months of no TRIM is hardly a small victory. In reality, it must have written 5x that much internally. If it had TRIM.......

Yeah, the G1 went pretty well :)
I just did 24h retention test on sandisk ... didn't worry it at all.
I'm sure the Sammy 830 has passed the 4PB mark by now...hats off to Samsung for one solid and steady controller and to Chris for puttin' the screws to it in the quest(s) to see which drives go above and (waaay) beyond expectations. Altho the controller does have a lot of nand to work with vs other drives tested...I'm betting the 128GB and 64GB do just as well with respect to those drive sizes. Getting 2PB out of a 64GB Sammy wouldn't be a huge shocker, tho it'd be damn impressive.

And that is 4PiB! Haven't had an erase failure in over 2 PiB.
:up:
Congrats to Sam(sung) and Chris.
Congratz Chris :clap:
Next stop 6 PiB.
Next stop could be never. At this rate, I'll be posing updates for the next 73 years.

I am surprised that such a drive can cost so competitively, could it even match SLC ?
what the ... ultra durable toughness drive like X25-V!
830's NAND is truly Toggle MLC.
Grateful to Christopher :clap:

May I dare dream of having a drive reach 1 PiB (well, without having to do something dumb like breaking out an Intel 510 or something!)
Since it came up, the 830 is using 27nm Samsung 1.0 Toggle. But IMHO the M4 getting 1.5PiB at 64GB is far more impressive... But it's only a matter of time before the 830 gets there.
Now you know how I felt. Finally, I just said "to hell with the dumb stuff," and got a 256GB 830.Quote:

The failure of each flash chip is statistically independent, which means it's more difficult to get a large drive with good quality flash chips together, than to get a small drive. Think of the cost of display/monitor - the price does not grow linearly with respect to area, but grows exponentially!Quote:
