SMR

Verified against: Seagate SkyHawk SATA product manual 100870481 Rev A · Checked

Sources disagree on this model

Seagate's own documents disagree about this family. The SkyHawk datasheet and the SkyHawk SATA product manual both state SMR for this part number, while Seagate's summary CMR/SMR list shows no SMR anywhere in the SkyHawk line. The part-number-level documents decide the verdict.

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 2TB ST2000VX015 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 ST2000VX015 CMR or SMR?

It is SMR. That comes from Seagate SkyHawk SATA product manual 100870481 Rev A, which is Seagate's own documentation for this exact part number rather than a capacity-level summary or a retailer listing.

Can I use the ST2000VX015 in a NAS or RAID array?

We would not. Shingled recording turns a rebuild into hours of the write pattern it handles worst, which can extend the window during which your array has no redundancy. For sequential and archival use outside an array this drive is fine.

What should I buy instead of the ST2000VX015 for a NAS?

A conventionally-recorded drive at 2TB or one step up. The table above lists what is in stock right now with live prices, and every model number linked there has its own verified page with the manufacturer source.
