No, at the family level, and for two independent reasons. Several BarraCuda models are shingled, which is bad for rebuilds. And the whole line is rated for a desktop duty cycle rather than continuous operation, which is true even of the conventionally-recorded models.
There is no single answer to whether BarraCuda is shingled, which is exactly why capacity-level lists mislead. Seagate's own datasheet shows the 4TB, 6TB and 8TB 3.5-inch models as shingled, along with the current 1TB, 2TB and 3TB models, while the 12TB and larger models are conventionally recorded.
That produces the counterintuitive result that the largest drives in this budget line are the safest ones by recording technology, which inverts the rule of thumb most buyers carry.
Our resolver pages give the answer per part number, and the difference between the ST1000DM010 and the ST1000DM014, same name, same capacity, opposite technology, is the clearest illustration of why the family-level question does not have a family-level answer.
Even where a BarraCuda is conventionally recorded, it is not built for the job. Seagate positions the line as desktop and compute storage, with a two-year warranty and a workload rating in the region of 55TB per year at roughly 2400 powered hours annually.
A NAS is powered 8760 hours a year. That is not a small overshoot of the rated envelope, and it applies to the 12TB conventionally-recorded models as much as to the shingled 4TB one.
Vibration is the other consideration people forget. A multi-bay enclosure puts several spinning drives in one chassis, and the rotational vibration each one produces affects its neighbours. NAS-positioned lines carry sensors and firmware for that; desktop lines generally do not.
Seagate's own NAS answer is IronWolf, rated at 180TB per year with a three-year warranty, and IronWolf Pro above it at five years with a higher rating. Western Digital's is Red Plus and Red Pro, and Toshiba's is N300. All are conventionally recorded across their lines, which removes the question entirely.
The price difference at any given capacity is real but smaller than people expect, and it buys a stated workload rating, a longer warranty, vibration handling and a recording technology you do not have to look up.
If budget is genuinely the constraint, the better economy is a smaller number of larger NAS-rated drives rather than more desktop drives. Fewer drives means fewer things to fail and fewer rebuilds.

No, and the blanket claim is wrong in both directions. Seagate's datasheet shows the current 1TB, 2TB, 3TB, 4TB, 6TB and 8TB 3.5-inch models as shingled, while the 12TB and larger models are conventionally recorded. The largest drives in this budget line are the conventional ones.
Because the recording technology is only one of the two objections. The line is rated for roughly 2400 powered hours a year against a NAS's 8760, carries a two-year warranty, and lacks the vibration handling that multi-bay enclosures need. A conventional BarraCuda is still a desktop drive.
It changes weekly with stock, which is why the table on this page is live rather than a recommendation frozen in prose. What is constant is that the NAS-rated lines from all three manufacturers are conventionally recorded, so the recording question stops being something you have to check.
Yes, and that is genuinely the right role for one. A backup target outside the array does sequential writes with no parity relationship to anything, which is exactly what the line is built for. The objections are all about being inside an array, not about being near one.
