A hydraulic roller should last 100k miles and more. Nothing different than an OEM hydraulic roller, which is what most OEM engines use....
The issue with a solid roller on the street is valve lash being introduced. Constant pounding of the bearings in the lifter take a toll and eventually the lifters have to be rebuilt.
Cheap lifters will last about 3000-5000 miles before they need rebuilt. Quality solid roller lifters with bushings instead of needle bearings can last up to 30000 miles.
