SSD Write Endurance 25nm Vs 34nm

None of the drives in the endurance test have been given additional overprovisioning.

All off them within a few days?

[canthearu]

Yep, all but 2 or 3 in the last 48h.

[Anvil]

The Kingston can go for months and then pop a few sectors.
Re-allocations have been showing movements for a long time though, they just don't accelerate like some other drives tend to do.

The cheese is sliding off the this one's cracker! ... 33 reallocations now (365.67 TiB in ASU)

[Anvil]

On the positive side, it does inform about whats to happen, much too early though.

Lets see how much it can take...

What about the Intel 520, it's been a few days without updates.

I just noticed it was yesterday , the extra reports on the Vertex made me think several days had gone by.

I'll update if canthearu posts on the 520.

The plan is to start testing a new drive tomorrow, that is if it gets here.

Looks like we are hitting 1 PiB with just a couple of days between us
I'm waiting a little with the C300. GullLars might sell me one of his C300 64GB when he updates his raid0 setup.

[Anvil]

It could be a close race to 1PB, 1 PiB you should win

I noticed the post about the C300, would be great!

[B.A.T]

I hoped the Samsung 830 64GB could join me all the way but sadly no.....

I wonder how far they can go?!? Looks like only the sky is the limit

[Christopher]

I really think that 830 64GB could have made it to the moon by now, it's too bad it went through weeks of super high WA. Had it not, it would have had 900TB when I stopped testing.

[canthearu]

Vertex 4 up to 52 reallocations (at 372.45 TiB in ASU)

The intel 520 is still running fine .... nothing really to report these except slightly higher write numbers

I'll do a full update tonight.

[DragoonXX]

have you done any recent data retention tests on the x-25v rebadge? or are you waiting to hit 1 PB? I'm still trying to figure out what i should do with my little tanks when i have money to upgrade (going from a pair of x-25V to I'm leaning towards an M4 128GB- only on a P45 chipset atm with them though)

[B.A.T]

I think Anvil is going to wait just like me until 1 PiB is broken.

[Anvil]

I'm waiting for 1PiB before doing more retention testing.

It had a very short retention-test about a week ago, just a few hours disconnected while reinstalling the rig.

I believe the last retention test was at 7 or 800 TiB, it lasted a full weekend w/o power.

The vertex 4 is killing blocks at an increasing rate. Things are progressing quickly ... there may not be a tomorrow for this drive. It seems to roughly doubling the block reallocation count every 24 hours.

The Intel 520 is just doing its thing, quietly and without fuss. Which means one day it will simply die without warning, shattering the dreams of it's owner, along with all their data .... where that point is, who knows.

Looks like my endurance rig has some kind of error, which means I get the occasional BSOD.

Sometime soon I'll need to run memtest86 on it to find out what is wrong and attempt to correct it. This will mean the drives will get at least a small retention test.

[Anvil]

Can you rule out that it's caused by one of the drives?

Are you able to catch what BSOD it is and is it the same one?

BTW, got a new drive for Endurance testing today, breaking it in as we speak
(just running some reference benchmarks and recording SMART, ...)
