HDD vs. SSD - Is the Upgrade to Solid State Hard Drives Worth the Added Cost?

I have used external HDDs (Hard Disk Drives) for my business since the Studio Opened in 2012. However, when I noticed my current HDD starting to operate poorly, I decided not to replace it with yet another HDD. I spent the extra money to purchase an external SSD (Solid State Drive).Yes, SSDs are faster and more reliable, but they Cost quite a bit more for less Storage Space compared to Hard Disk Drives. Are they worth the extra Cost? Share your thoughts.
