Quick answer
Which one should you choose?
Choose Toshiba N300 8TB for the strongest cited sequential performance: the current HDWG780EZSTA is rated at 7,200 RPM, 281MB/s and 512MB cache. Choose IronWolf ST8000VN002 for lower power and quieter operation, or ST8000VN004 for a 7,200 RPM IronWolf with Seagate Rescue and compatible-NAS health features. There is no single IronWolf 8TB specification, so verify the exact ST model before comparing prices.

The N300 is clearly faster on the specification sheet
Toshiba rates the current N300 8TB at up to 281MB/s with 512MB cache and 7,200 RPM. Seagate rates ST8000VN004 up to 210MB/s and ST8000VN002 up to 202MB/s, both with 256MB cache. For local sequential workloads, multi-gigabit networking and RAID rebuilds, the N300 has the strongest headline performance of the three cited mechanisms.
That does not mean a home user will see a seventy-megabyte-per-second difference during every file copy. One-gigabit Ethernet is slower than all three. Small files, NAS CPU limits and parity calculations also change the outcome. The N300 advantage is most relevant when the rest of the system is fast enough and the workload moves large amounts of data.
IronWolf 8TB is not one product profile
ST8000VN002 is a 5,400 RPM model rated up to 202MB/s, 5.3W operating, 4.0W idle, 25dBA idle and 26dBA seek. ST8000VN004 is a 7,200 RPM model rated up to 210MB/s, 10.1W operating, 7.8W idle, 28dBA idle and 32dBA seek. Treating both as a generic IronWolf 8TB creates a false comparison.
The lower-RPM ST8000VN002 is the quiet-efficiency choice. ST8000VN004 is closer to the N300's performance-first character but still has a lower cited sequential rating and smaller cache. Retailers may merge both drives or older stock into one search result, making the complete model number essential before price or noise claims are trusted.
N300's performance comes with a substantial acoustic cost
The current N300 8TB lists 34dB typical idle, considerably above both cited IronWolf models. Toshiba's sheet does not provide a seek figure, so the complete sound character cannot be reduced to one number. Even so, the idle rating makes N300 a risky default recommendation for a bedroom, studio or desk-side enclosure.
A NAS chassis can amplify vibration, and four drives do not sound like one drive multiplied linearly. Beat frequencies, tray resonance and fan response can make the array more intrusive than expected. In an isolated rack or utility room, the N300's sound may be irrelevant. Near users, ST8000VN002 is usually the safer starting point.
Power affects heat, fans and five-year cost
N300 8TB is rated at 9.07W operating and 5.74W active idle. ST8000VN002 is rated at 5.3W operating and 4.0W idle, while ST8000VN004 is rated at 10.1W and 7.8W. The quiet IronWolf therefore has a clear efficiency advantage, while the faster IronWolf is actually heavier than the N300 in the cited power figures.
Across four or eight drives, these differences change internal heat and fan speed as well as electricity cost. Use the calculator with the local tariff and a realistic active-duty cycle. Do not reduce cooling below safe temperatures merely to save energy or noise. Proper airflow and a clean power supply matter more to the array than a small annual electricity difference.
Seagate adds support features Toshiba does not list
The cited IronWolf models include three years of Rescue Data Recovery Services where available and can expose IronWolf Health Management on compatible NAS platforms. Those features do not improve raw speed, but they can influence the value calculation when prices are close. Verify regional Rescue eligibility and the exact NAS compatibility before relying on either benefit.
Toshiba provides NASLink firmware, rotational-vibration sensing and the same three-year warranty class, but the cited N300 sheet does not list bundled recovery. A buyer with a strong independent backup may place less value on Rescue, while a small office may appreciate an additional recovery route. Neither feature set makes RAID a backup.
Which one is better for Plex and backups
All three drives can serve multiple Plex streams because compressed video bitrates are far below their sequential capability. The NAS processor's ability to transcode is usually more important. For a quiet living-room Plex server, ST8000VN002 is attractive. For rapid local ingest, backup windows or a 10GbE editing workflow, the N300's higher rating is more relevant.
Backup targets often spend long periods idle and then perform large sequential writes. That makes both energy and burst workload important. The quieter IronWolf can be the better always-on home backup drive, while N300 can finish a large local backup sooner when the network and source are fast. Use the actual duty cycle rather than a generic benchmark.
Array sizing can matter more than the model difference
Four 8TB drives provide 32TB raw capacity and roughly 24TB with single parity or 16TB with dual parity or RAID 10, before overhead. If that usable capacity is already marginal, debating N300 versus IronWolf may be less important than moving to 12TB drives. Expansion strategy should be settled before optimizing an 8TB mechanism.
A larger drive can reduce bay count, but also increases rebuild time and data concentration. Keep an independent backup and consider a spare strategy. For a large array, verify whether the NAS supports mixing exact revisions and whether vibration limits are appropriate. Both cited families are intended for up to eight bays, but enclosure quality remains important.
Buy according to the room and exact checkout price
Choose N300 8TB when performance is the first priority and the NAS is isolated. Choose ST8000VN002 when silence and efficiency matter. Choose ST8000VN004 when you want a 7,200 RPM IronWolf and value Seagate's support features, but compare its power and price carefully because it can be less efficient than N300.
Confirm the model number, condition, seller and warranty region before ordering several drives. A bargain listing that silently substitutes an older or different suffix can invalidate the comparison. Test every disk with extended diagnostics before building the production array, and retain serial and purchase records for warranty handling.
Plan for replacements before one of the 8TB models disappears
Exact 8TB revisions do not remain on sale forever. A replacement bought two years later may carry a different model number, spindle speed or acoustic profile even though the family and capacity are unchanged. RAID normally accepts a replacement of equal or larger capacity, but the array can become limited by the slower member and may sound or run differently after the swap.
Keep the original model numbers in the NAS inventory and retain enough free capacity to tolerate a rebuild. When a matching drive is unavailable, compare sector format, supported NAS list, workload class and physical mounting rather than chasing an identical label at any price. A current compatible replacement is usually safer than questionable old stock sold without a clear warranty.
