One thing I noticed is that the 512GB Vertex 4 in my array with the 8 bad sectors has the serial number starting with 2Y3U... The other five 512GB Vertex 4 drives have the serial number starting with OCZ-...

The drive appears to be from a very different batch.

One good reason to buy Plextor. As Mark R mentions, testing is not cheap.

Just performed a chkdsk on the array. It seems OK after about a months use.

A week later and no change:



I started SSD Sentinel every day since last week to get proper logging. Looks like the 8 sectors on this drive and the 1 sector on the drive below it has the bad sectors noted from manufacturing.

BTW - How do I translate the "Total Count of Write Sectors" into something understandable? The drive in the screenshot currently shows 3,006,165,257. Disk 2 in the same array shows 558,279,319. The 256GB Vertex 4 that I've had since September shows 259,787,698.

Not sure why each drive in the 3TB array has different write sector counts. The drives have been used in the same array and have never been used by themselves.

Update:

Four months later and no change in reallocated sectors on any of the drives. Bought two more for 8 in RAID-0. One came with 1 reallocated sector and the other came with 2 reallocated sectors from the factory.

Nine OCZ drives and no failure? According to the brilliant people on this sub-forum, the odds of an OCZ drive failing on me should have occurred by now.

Adam, I have bought 6 or more OCZ ssd's over the last couple years and all are still happily ticking away. I think a lot of problems are user specific more so than product specific. Some people always have issues while others little to none.

OCZs older drives (Vertex 2 and 3) were known to be problematic. They may have gotten QC in order with later products.

It's a very nice app. Hardware.Info is actually using it in their live stream Samsung 840 endurance video.

I don't think the thing has ran for a full day because TB/s written per day is at 7.25 and rising (edit: reached 7.65 and rising very slowly now, prob level out not much higher than that). Not sure what it will but at that amount per day, the chart shows Wear Count to reach zero in 9 months. Will be sooner when TB/s per day level out though. Still pretty impressive even for the TLC memory. Basically only thing to worry about is how reliable the firmware is for any specific drive these days...

Yep, looks fine to me.

Just for the record, all 9 of my Vertex 4s are still going strong. Sorry to be the bearer or bad news to those who don't like OCZ.
