HDD problems on my MacBook Pro 13" Mid 2012

My MacBook Pro started getting incredibly slow a while back, many tiny processes like opening Mail required a lot of CPU power and took for ever. Until later , a few days ago, it wouldn't startup anymore. It just couldn't get past some error with "disk0s2" or something of that nature.

After a few hours, a timemachine backup and completely new software the Pro would start again. Only all other problems I'd been having before the new software etc. remained the same. So I did a EtreCheck. everything was fine but the HDD, it sayd: "Macintosh HD (disk0s2 - Journaled HFS+) / [startup]: 499.25 GB (177.28 GB free) - 180 errors Drive failure!".

After this I ran all verifications and maintainence procedures of OnyX and actually got a great result. EtreCheck now stated: "Macintosh HD (disk0s2 - Journaled HFS+) / [startup]: 499.25 GB (177.28 GB free) - 27 errors Drive failure!". My MacBook Pro had much less issues than before though I'm not really satisfied.

So I was hoping you could help me out with this issue. I'm buying a new MacBook Pro in 3 months so I'm now willing to invest over €70,- and rather non at all of course. Below is a short discription of my MacBook Pro's hardware just in case.
