That depends on the size of the data set, i.e., how many PCs are included in the group they're considering, the age of the PCs, and the length of time. For example, we learned the original "seven drives" failed over a three year period, from 2011 to 2014. It would probably also be useful to learn what they mean by "crash". For example, is that just drive failures or does it include related problems like corrupted OS and physical damage due to drops, spills, etc?
Once again, we need to get the politicians and executives out of the middle of this, and get real data directly from IRS IT. Right now we have too many clueless officials trying to paraphrase and interpret, leaving everyone in the dark. Let's hear actual data instead of the spin of partisan actors.
Edit: one note of caution re. this new story -- I did a little digging at more reputable sites. This story is apparently based on a partial transcript of testimony, released by Republican members of the House Ways and Means committee. In the past, when Darrell Issa released partial information, it invariably turned out to be cherry-picked statements, deliberately taken out of context to be deceptive. Whether the Ways and Means members who released this partial transcript are equally slimy has yet to be seen. Hopefully not, and hopefully we will get the full transcript soon so we can review the entire testimony,
