Likewise, which is better for NAS CMR or SMR?
Users should evaluate their storage and backup needs carefully to determine the drives that work best for them. In principle, SMR drives will deliver the same capacity as CMR drives at a much lower cost per platter, but offer less usage flexibility.
Beside above, are SMR drives bad? They're slower than regular HDDs and they don't always play nice with PMR drives or other file systems. Random write performance on SMR drives is particularly bad, so if you have workloads that depend on it you absolutely don't want to run them on an SMR HDD.
People also ask, why SMR drives are bad?
It can get bogged down during large writes and become very very slow, like 10MB/s on average slow. Reads are fine it is only writing that is affected. That being said, the SMR technology does make this drive one of the best for $s/TB on the market, just don't expect amazing performance from it.
Is WD Blue CMR or SMR?
Western Digital released a statement showing which drives from their HDDs series use the slower SMR technology and which ones make use of the faster CMR technology. Drive series featuring SMR include the WD Red and WD Blue HDD series, both of which come in a 3.5" form factor.
