Vertex 4 reallocated sectors at 15.
I'm seriously doubting this drive is going to last more then another 100-200TiB.

12 new bad blocks for the vertex 4. Upgrading ASU and restarting testing.
What sort of over-provisioning is there by default on the Vertex 4?
@Anvil
The normal 7% from the conversion of binary gigabytes (GiB) into decimal gigabytes. (GB)
OK, so the norm then.
I normally over-provision ~10% on most drives, especially if they are in a raid.
(during my V4 128GB testing it has been set to 100GB, 19.5GB over-provisioning)
I've been a fan of OCZ for a few years now for putting to market many new interesting products.Quote:

Just out of curiosity are you guys doing this with MHDD or similar (cutting the drive/changing the MaxLBA) or is this something else with a custom firmware? The handful of SSD's here I've just cut the drives but haven't really done a lot of stress testing to see the efficacy of that.Quote:

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)Quote:

Lets see how much it can take...

Another realloc happened last night.
What about the Intel 520, it's been a few days without updates.Quote:

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.
It could be a close race to 1PB, 1 PiB you should win :)
I noticed the post about the C300, would be great!
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 :)
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.
