[SOLVED] Which SSD should I choose for OS

[Madanach]

Hello, I have 2 SSD. One is old but faster and the other one is new, reliable but slower. I couldn't choose which SSD for installing OS. The old one's health bar worries me for long term.
Both device's CrystalDisk reports here.

The old one; ADATA SX6000NP, in short 1000/800 Mb/s and Nvme 1.2 (3 Years old, %72 Health)
The new one; Samsung 870 EVO, in short 560/530 Mb/s and SATA3 (New)

Pretty good chance you couldn't tell the difference.

I'd be more inclined to choose on the basis of size.

If they are not the same size, I'd probably use the smallest one for OS and apps assuming it is still large enough for estimated future capacity requirements......particularly if you have some good way to use the larger one, probably for storage.

I wouldn't get excited about that 72% at all.
