About this tag
Shingled Magnetic Recording (SMR) hard drives have a reputation for poor sustained write performance, as their firmware can struggle and cause pauses during continuous writes. This makes them unsuitable for RAID arrays or NAS environments where consistent write speeds are critical. However, SMR drives can still be useful in specific scenarios, such as when used in a RAID 0 array with multiple spindles, where their higher rotational speed and large buffer may offset some limitations. The discussion highlights that while SMR drives are often dismissed for demanding workloads, they can serve niche purposes like bulk storage or non-critical data where write performance is less important.

What use are SMR HDD's
Shingled Magnetic Recording drives have a bad name, and rightly so if you need to write continuously for more than a couple of minutes, because the firmware just can't cope and frequently grinds to a halt for a few seconds. As someone who always buys NAS HDD's for their longevity and durability...- RobertP
