IronWolf 4TB: specifications and dated store comparison →A modest-capacity drive for household backups and shared files, with room to grow only if 4TB is enough.
One 4TB Seagate IronWolf ST4000VN006 internal SATA hard drive. NAS enclosure sold separately.
This guide combines Seagate DS1904.23 for ST4000VN006 with a TechRadar PC comparison against WD Red Plus 4TB and a Hardwareluxx reader rebuild on a QNAP TS-473A. The drive is 5400 rpm CMR and only 20.20 mm tall. ChooseCompute has not tested this drive. See the review evidence ↓
A practical starting point when your files and expected growth fit comfortably within 4TB.[1][2]
The direct PC test supports straightforward file transfers; a separate QNAP test also exercised a mirrored pair.[2][6]
A 4TB drive uses one enclosure slot just like a larger drive. Starting small can mean replacing it sooner.[1]
TechRadar found the WD Red Plus comparison drive quieter. There was no controlled sound-level test.[2]
Follow any specification for its full conditions and sources.
Living with it
Choose 4TB when it covers your existing files plus realistic growth. If you already expect to exceed it, compare larger drives before filling your enclosure: the smaller drive saves capacity you pay for today, but may require an earlier replacement.[1]
TechRadar’s PC test placed this IronWolf near the WD Red Plus in sequential transfers, while some latency results favored WD. That makes the IronWolf a reasonable file-storage choice, without establishing that it is faster for every task.[2]
The Hardwareluxx reader measured 215.60 MB/s read and 216.27 MB/s write in CrystalDiskMark 9 sequential Q8T1, using three 1 GiB passes on an empty drive through a SATA-to-USB 3.0 adapter. This was separate from the QNAP mirrored-array recovery exercise, which did not report a rebuild duration.[6]
Seagate specifies 3.7W during operation and 3.2W at idle. Those figures describe the drive, not a complete NAS. Do not assume the 5400 rpm label guarantees a quiet desk setup: enclosure vibration and the reviewer’s unfavorable noise comparison still matter.[1][2]
DS1904.23 lists ST4000VN006 at 20.20 mm height and 490 g, versus 26.11 mm typical height on the 8TB-and-up helium IronWolf columns in the same sheet. That is a published mechanical difference. No compatibility source was adopted that names specific NAS trays this drive does or does not fit, so tray fit remains something to check on the enclosure you own.[1][2][6]

In a single-drive PC comparison, AJA reported 190 MB/s read and 185 MB/s write. The author regarded small sequential differences as inconclusive and preferred WD for noise. Full PC settings were not disclosed.

A Hardwareluxx reader used two SC60 units in a QNAP TS-473A, removed one from the running mirror and restored the volume after reinserting the reformatted drive. The supplied-hardware test gives no rebuild duration or universal compatibility guarantee. Separate original single-drive USB-adapter screenshots show CDM9 sequential215.60/216.27MB/s with three1GiB passes; this is a different path from the NAS recovery exercise.

Before you buy
On 2026-09-11, the primary Newegg-sold listing showed $189.99 for one new ST4000VN006 in stock. Older B&H and Amazon offers retain their original observation dates; compare availability and delivered cost before ordering.[8]
Compare the total cost of the capacity you expect to keep using. A cheaper initial drive can become an extra purchase if your library outgrows 4TB.[1]

Not exactly. The label uses decimal capacity, and formatting reduces available space. Your redundancy layout can reduce it further; two mirrored drives do not double usable capacity.[1][6]
No. Match ST4000VN006 on the listing and the delivered drive. This page covers the 5400 rpm, 256MB-cache model; another suffix is not automatically the same hardware.[1]
Quietness is not established. TechRadar preferred the WD comparison drive’s noise, and the available test does not provide controlled sound-pressure measurements.[2]
