In all honesty...I find it hard to believe that an app can have a negative impact...because of the storage medium used. I didn't look very hard but the articles I reviewed indicate that there is no problem.
As far as SSDs versus HDDs...the purported limited read/writes...if such exists...certainly is preferable to the current expected failure rate of any HDD, IMO. The only thing mandating against at total obsolescence of hard drives, IMO...is the price/capacity of current SSDs. HDDs are the clear winner when it comes to storage capacity...but there is that general, unpredictable failure rate that many users don't seem to consider realistically.
