Best solution

Hard drive won't come close to the SSD. Without a benchmark on those two selections it's hard to give you a number, but the SSD will be 10 times faster. For what I do an SSD is exactly what I need. And data hungry application does benefit from an SSD

While that blue drive has good sequential speeds (150 MB/s on average), the average seek time is 20 ms. The seek time of an SSD is less than 1 ms, typically 0.1 to 0.5.

I use that blue to back up my ssd, because backups are streaming sequential access, not random.
