I think the lifespan of SSDs should not be much worse than HDDs, in some cases they may even last longer depending on the usage, as there is no mechanical wear and tear as with HDDs.
However, the question is whether it is worth the extra cost to switch to an SSD.
Speed-wise you are slowed down by the 2x 1Gbit ports of the DS419Slim (I think it is this one, because as far as I know there is no RS419). The only advantage I can see is that your NAS would then be practically silent because the SSDs don't make any noise.
Yes, it is compatible, but according to this installation guide, you also need a mounting frame like this :
- Mushkin SSD 2.5" auf 3.5" Einbaurahmen
- Corsair Montagehalterung 2.5" zu 3.5"

According to this guide, you can replace the optical drive and install the SSD with this mounting frame :
RaidSonic ICY BOX IB-AC649 So you will have Dual Drives. CDs are almost obsolete at the moment.
Read/write rate of the Sandisk is a little faster, but Max. Random 4K Read/Write are higher on the Samsung.
In everyday use you won't notice a tangible difference just because the values are so close to each other, it only becomes noticeably faster/slower in benchmarks.
