What does Raw Read Error Rate mean in SSD SMART

diagnostichard drivesmartssd

I downloaded trial version of HD Tune Pro and I'm using it to benchmark my hard drives. In Health tab of SSD I found Raw Read Error Rate property. What does this property say about my hard drive?

enter image description here

OCZ tool shows only 114 total ECC and RAISE errors. But what does Data column in HD Tune mean? Why the description says that disk had 89.970.873 read errors? It is new disk. I installed it yesterday and it is passing all diagnostic tests in SeaTools, Performance tests in HD Tune Pro and common check in Chkdsk.

The HD Tune data looks quite suspect. For example, I don't believe that you had a temperature peak of 129 degrees celcius. And as you say, the ECC recovered rate is simply ridiculous.

Since this is an OCZ disk, I would go with OCZ tool, and take its findings as the correct ones.

If you are worried about 114 ECC and RAISE errors, the best is to get in touch with OCZ Support, and ask if they advise to use the warranty to exchange the disk. Their answer, if positive, will give you the necessary ammunition when dealing with your vendor.
