I have gotten the opinion of one very knowledgeable person on this question (forum on another site), but would love to see if other knowledgeable people agree.
Just bought a new Western Digital 2.5 inch drive, 1TB.
As described below, diagnostic software logged 125 warnings for this drive, and I'm wondering whether I should RMA it.
The last 5-10 drives I've bought I've 'burned in' & tested by doing several passes of a secure erase (i.e. writing to the entire drive), then running a utility like Victoria to do a surface scan, which also gives response times for each block, then checking SMART values. Part of the idea is that any serious problems may show up as a change in the SMART values after exercising the drive.
Not sure if 'response time' is the correct terminology, but this version of Victoria displays a sort of histogram of block response times, logging a warning for any that are over 160ms (flagged in yellow), and a more severe warning for those over 600ms (flagged in red).
In the past I have almost never gotten any warnings on a new drive, and if so there was only one.
This time there were 125 warnings, with times ranging from 194ms up to 349ms, uniformly distributed throughout the drive. Normally roughly 98% of the values are less than 5ms, about 2% between that and 15ms, and the remaining very few between that and 120ms.
The crucial SMART values are all OK.
What do you think? Should I RMA the drive?
Your insights are much appreciated.
