Geek Complaints Because Size Does Matter

If you’ve ever bought a harddrive you know that what is said about it’s size on the package doesn’t equal what Windows says the drive is. What I am really starting to hate is that now that the drives are so damn big I’d say it’s a fraud selling a harddrive as 3TB when in fact it’s only 2.7TB.

The geeky explanation why this has happened is : When 1 kilobyte was established it was with binary math as 2^10 = 1024 bytes. But with the next step, megabyte, math says that 2^20 = 1048576 bytes. But the manufactureres didn’t like that so they decided that 1MB = 1000KB. And now that we are talking TERABYTES this math has gone so wrong that an average disk sold as 1TB disk will in fact only be 931 megabytes (or 0.9TB) in Windows and any other OS or application. That’s almost 7% gone because the manufacturers are saying one thing when math says another.

Why is this bothering me now? Because now I have 5x3TB harddrives in a RAID5 at home. RAID5 means that 1/[number of disks] of space is wasted for parity so I can retain the data if one drive fails. In this case that’s 1/5, that’s 3TB, is gone for that. So 5*3-3 = 12TB. So I should have 12 beautifull TB of space. But I only have 10.8TB. That’s 1.2TB gone – 11% because manufacturers are taking the piss out of math. And it’s really starting to piss me off now that we’re talking about drives in the TB class!

Do you know any other market where a retailer sells you something and you totally accept to only get 89% of what you paid for becuase of math?!

And now you might start to realise … I can do clickbait to! 🙂

So Very Close

Just a little personal congratulations to myself for having passed 6 Microsoft exams now, and I’m just one little exam away from being a Microsoft Certified Solutions Engineer. I don’t know why that makes me gigly, not likes it’s going to go down well with the ladies but for me it’s a big deal. And it’s not going to give me a payraise nor going to stop my ear from peeping. So it’s just to boost my ego. If all goes we’ll I’ll be on the advanced Sharepoint 2013 course in one month and write the last exam after that for that glorious title.

Yay for me.
