This article covers 【整備済み品】Seagate Enterprise Capacity 3.5.

Overview

The Seagate Enterprise Capacity 3.5 ST4000NM0035 is a 4TB, 7200RPM, 128MB cache internal hard drive designed for enterprise workloads. It uses a SATA 6Gb/s interface and comes in a standard 3.5-inch form factor. This particular unit is sold as a renewed (refurbished) product via Renewed, offering a cost-effective way to obtain enterprise-grade reliability without paying full retail price. The drive also carries FIPS 140-2 certification, making it suitable for security-conscious environments. As part of Seagate's Enterprise Capacity line, the ST4000NM0035 is built for 24/7 operation in NAS, RAID arrays, and server racks. It boasts an MTBF of 2 million hours and an annualized failure rate (AFR) of 0.44%, far exceeding consumer-grade drives. The 512n sector format ensures compatibility with legacy systems, which is a plus for users running older operating systems or controllers. Priced significantly lower than new enterprise HDDs, this renewed drive is an attractive option for budget-conscious users who still need reliability. However, because it is refurbished, the condition and warranty terms should be verified before purchase.

Compatibility Guide

This is a standard 3.5-inch SATA drive. It fits into any desktop PC, NAS, or server bay that supports 3.5-inch drives. The interface is SATA 6Gb/s, backward compatible with SATA 3Gb/s ports, though using a SATA 3Gb/s connection will cap transfer speeds. Power is supplied via a standard SATA power connector; the drive draws about 5.5W idle and 8.5W during seek, well within the capacity of any modern PSU. The drive is compatible with Windows, macOS, and Linux. The 512n sector format works seamlessly with most systems, but if you plan to mix it with 4Kn drives in a RAID array, check your controller's support for mixed sector sizes. For optimal performance, use a SATA 6Gb/s port on your motherboard or controller.

Product Info

The Seagate Enterprise Capacity 3.5 ST4000NM0035 is a high-end enterprise HDD originally released under the Enterprise Capacity 3.5 HDD v4 series. The renewed units sold via Renewed have been tested and certified to work properly, typically with a 90-day warranty (varies by seller). Market positioning: this is a mid-to-entry-level option for users who want enterprise reliability on a budget. Compared to brand-new enterprise drives, the price is significantly lower, making it a compelling value proposition. Key specs: 4TB capacity, 7200 RPM spindle speed, 128MB cache, SATA 6Gb/s, 512n sector format, FIPS 140-2 certified, MTBF 2 million hours, AFR 0.44%, max sustained transfer rate ~215 MB/s.

Best Use Cases

NAS and home server builders: The drive is designed for continuous operation in RAID arrays, making it ideal for 24/7 NAS applications. Its high endurance and reliability are perfect for storing media libraries, backups, and shared files. Not recommended for silent builds?the seek noise is noticeable. Budget-conscious users needing high reliability: If you want enterprise-grade reliability without paying full price, a renewed ST4000NM0035 is a smart choice. You get the same engineering as a new unit at a fraction of the cost. Avoid if you demand absolutely pristine condition or a long warranty. Security-sensitive environments: The FIPS 140-2 certification means the drive meets government security standards, so it can be used in regulated industries. However, note that the certification covers the drive's security features, not hardware encryption alone. Large-capacity backup storage: 4TB is enough for photo libraries, video archives, and file backups. For heavy 4K editing or massive data hoarding, you might need more capacity, but this drive works well as a secondary storage device. ## Alternatives
A direct competitor is the Western Digital WD4000FYYZ (WD Re 4TB), also an enterprise 4TB 7200RPM SATA drive. Both offer similar MTBF and AFR ratings. The key difference is sector format: the ST4000NM0035 uses 512n, while the WD Re typically uses 512e (emulation). If you have legacy hardware that requires native 512-byte sectors, the Seagate is the better choice. The WD Re may have a longer warranty when bought new, but for renewed units, warranty terms vary. Another alternative is the Toshiba MG04ACA400E, which is similar in performance but often priced higher in the renewed market. Availability of Seagate renewed units is generally broader, making the ST4000NM0035 easier to find at competitive prices.

Things to Consider

First, this is a refurbished drive. While Renewed testing ensures it's functional, cosmetic blemishes and some wear are possible. The warranty is only 90 days, so if you need long-term peace of mind, consider a new drive with a multi-year warranty. Second, the 512n sector format is becoming less common. Modern systems often use 512e or 4Kn. If you plan to use this drive with a very new RAID controller or OS that expects 4Kn, you may encounter com
