Using SMR hard drives


Recommended Posts

I'm exploring various ideas for a NAS with a low physical and power footprint that could be placed remotely and one thought is to use a small 1L desktop with a 2.5" HDD. The largest one is 5TB but SMR and I'm hoping someone can share their experience with using SMR drives for backups of PCs or MacBooks which should present a sequential write workload. Are only random write problematic for SMR HDDs?


Also, some of these drives are reported to support TRIM. I had only heard of TRIM in the context of SSDs which DSM only supports as caches, so would DSM support TRIM on a HDD and would that make a difference in this use case?




P.S.: It is not really a hardware mod question but I wasn't sure where to post it
