With SSDs reaching a brand new stage of affordability, we not advocate utilizing mechanical arduous drives as main system storage. Nonetheless, for a secondary drive with substantial storage capability, Seagate IronWolf NAS drives stay unbeatable.
Being NAS-optimized, the IronWolf series just isn’t cheap for a disk drive, as it’s designed for intensive workloads involving fixed learn/write operations over prolonged intervals. These drives are extra dependable, supply greater capacities, and carry out properly (for a tough drive). It is price noting that higher-end sequence just like the IronWolf Professional and Exos are meant for bigger servers and focus extra on vibration resistance than on efficiency.
The newest IronWolf HDDs can be found in capacities of 1/2/3TB (5,900 RPM, 64MB cache), 6TB (5,600 RPM, 256MB cache), and eight/10/12TB (7,200 RPM, 256MB cache). The latter variations include a five-year guarantee and three years of knowledge restoration providers. Moreover, these drives use standard magnetic recording (CMR) expertise as a substitute of shingled magnetic recording (SMR), avoiding the write efficiency penalty related to SMR utilized in cheaper, denser disks.
Inevitably, this additionally means paying a small premium over funds drives. For instance, an 8TB IronWolf drive will set you again around $170, whereas an equivalent capability Barracuda will be had for $125.
A Worthy Different: WD Pink Plus
WD NAS drives have been priced to compete with Seagate’s IronWolf throughout their complete vary of 1/2/3/4/6/8/10/12/14TB fashions. There are, nonetheless, minor spec variations between the 2, together with RPM speeds and cache measurement. Notably, the most recent model of the Red Plus drives supply 512MB of cache within the 12TB and 14TB fashions. Nonetheless, these nonetheless include three years of guarantee.
HDD Funds Possibility
In the event you merely need a reasonable, barebones HDD, the Seagate Barracuda line has quite a lot of choices to get you probably the most storage to your cash. A 4TB mannequin will be had for just $80, or you possibly can double the area with the capacious $125 8TB model. The Barracuda can also be accessible in 1TB, 2TB, 3TB, and 6TB variants.
The 2TB mannequin of the Barracuda is the candy spot when it comes to velocity, spinning at 7,200 RPM with 256MB of cache. The 1TB mannequin spins on the identical velocity, however solely contains 64MB of cache. The 3TB and above fashions decelerate to 5400 RPM, however we predict that is affordable for the worth. A bigger cache is beneficial for storing incessantly used recordsdata with no need to maintain them on the slower disk.
