What does Raw Read Error Rate mean in SSD SMART?
Solution 1
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.
Solution 2
Just like to add that the errors are correctable, so programs don't get to see them but all the same, I would not expect to see any real read errors from SSDs. I would seek further clarification from the manufacturer. Hopefully one day we'll have SSDs that don't wear out.

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?
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. -
Karlows the dwarf about 13 yearsThe Current and Worst values for temperature can never be read directly from SMART data. The software has to convert it into a readable value, sometimes this varies by drive too so the software has to be coded for certain drives. I don't know about HD Tune Pro but I know Smartmontools can output the correct temperature for most drives.

Ladislav Mrnka about 13 yearsCan you also explain what does Raw Read Error Rate mean?

harrymc about 13 yearsIt means the drive has bad blocks that prevent the computer from reading its contents normally. A high rate means that the disk is failing, which is why I suggested to contact Support, just in case.

Synetech almost 13 years@harrymc, the temperature field is probably reporting in Fahrenheit.
