I passed by the local computer store earlier in the evening, and noticed they had four SH224FB drives in stock with a January 2016 manufacturing date. They also happened to be on sale.
This is the only nearby store which sells through inventory relatively fast. (The other nearby computer stores seem to take longer to sell through the dvd drives inventory, and/or they don't carry any Samsung models).
I gave in and purchased all four SH224FB drives.
Ripped ten+ dvd discs on two of these new drives. Will rip through several tv show dvd season sets on the other two drives, to see if there's any immediate problems.
So far I haven't been using my Samsung drive as a primary nor secondary ripping drive. I have only really used my (first) Samsung SH224FB drive for dealing with basketcase dvd discs, which the LiteOn and LG can't rip properly at all. More recently, I've occasionally used my (first) SH224FB drive to rip some tv show dvd season sets released by 20th Century Fox. (Apparently Fox's quality control has deteriorated greatly over the past several years, for their multidisc dvd sets).
I suppose now I can just alternate between several SH224FB drives, when ripping cantankerous tv show dvd season sets manufactured by Cinram. (ie. Fox and Lionsgate were Cinram's largest clients for bluray/dvd disc manufacturing until late last year, when Cinram was bought out by Technicolor).
Otherwise my LiteOn drives are my primary ripping drives, and the LG drives as secondary drives. (ie. Secondary drive for ripping dvd discs a second time, and subsequent times).
