Retail carton SKU for the DT01ACA100 mechanism.

What this means for you

Conventional recording writes tracks side by side without overlap, so a write never forces the drive to rewrite neighbouring data. That makes the HDWD110 safe for every use including RAID, ZFS, a NAS, and anything with sustained random writes. A rebuild or a resilver on this drive behaves the way the array expects, which is the whole reason the distinction matters. There is no recording-technology reason to avoid this drive for any workload.

Frequently asked questions

Is the HDWD110 CMR or SMR?

It is CMR. That comes from Toshiba DT01-A series desktop HDD product overview, which is Toshiba's own documentation for this exact part number rather than a capacity-level summary or a retailer listing.

Can I use the HDWD110 in a NAS or RAID array?

Yes. Conventional recording means a write never forces neighbouring tracks to be rewritten, so rebuilds and resilvers behave normally. There is no recording-technology objection to this drive in an array, check the workload rating and warranty for your duty cycle separately.
