Sources disagree on this model

Toshiba names HDWD260UZSVA in its SMR statement. Retail P300 6TB uses the shingled DT02 mechanism.

What this means for you

Shingled recording overlaps tracks like roof tiles to raise density. Reading is unaffected, and for sequential work, archives, media libraries, backup targets, files written once and read many times, this drive is genuinely fine and the saving is real. The problem is sustained random writing, because modifying data under an existing track can force the tracks above it to be rewritten too. A RAID rebuild or a ZFS resilver is hours of exactly that pattern with no idle time to recover, so a 6TB HDWD260 in an array can extend a rebuild dramatically, and the rebuild window is precisely when the array has no redundancy left. Do not put this drive in a NAS or a parity array.

Frequently asked questions

Is the HDWD260 CMR or SMR?

It is SMR. That comes from Toshiba statement: use of shingled magnetic recording (SMR) technology in Toshiba consumer hard drives (April 2020), Toshiba's own documentation for this exact part number, which also states the 2-year warranty on the spec table; the cheapest in-stock conventional pick right now is the WD Red Plus 10TB WD101EFBX.

Can I use the HDWD260 in a NAS or RAID array?

We would not: Toshiba statement: use of shingled magnetic recording (SMR) technology in Toshiba consumer hard drives (April 2020) states SMR for the HDWD260, and shingled recording turns a rebuild into hours of the write pattern it handles worst. The page's own in-stock conventional alternative right now is the WD Red Plus 10TB WD101EFBX. For sequential and archival use outside an array this drive is fine.

What should I buy instead of the HDWD260 for a NAS?

A conventionally-recorded drive at 6TB or one step up - right now the table's top in-stock pick is the WD Red Plus 10TB WD101EFBX. Every model number linked in the table has its own verified page with the manufacturer source.
