One if the ways that SSD life can be extended is to write less than the full disk. If your device supports it, sometimes these unused sectors can be used for remapping and included in the wear-leveling algorithms. Of course, the nano builds contain an entire partition full of bits that are unlikely to ever be used AND which can't be used as spare blocks (because entirely useless bits occupy your SSD.) Simply using a larger SSD (that has a decent wear-leveling algorithm) will greatly increase the TBW figure. Compression is another tool. Again, fewer bytes written. Finally, the eMMC parts we use on the coming Netgate boards can be put in a mode that halves the capacity in exchange for a 5X increase in write endurance. "Just use the nano build" isn't going to cut it. Jim _______________________________________________ List mailing list [email protected] https://lists.pfsense.org/mailman/listinfo/list
