This article covers 東芝 N300 PRO 24TB 大型ビジネスNAS (最大24ベイ) 3.5インチ 内蔵ハードドライブ.

Overview

The Toshiba N300 PRO series is a line of internal hard drives tailored for medium to large business NAS environments. The 24TB model (HDWG82EXZSTB) brings an increased workload rate of 550TB per year, designed for 24/7 multi-user operation. It spins at 7200RPM and features up to 1.0GB of cache, ensuring fast access to large datasets. Utilizing CMR (Conventional Magnetic Recording) technology, it offers stable write performance and broad compatibility with RAID configurations. An integrated RV (Rotational Vibration) sensor further enhances reliability in multi-bay enclosures.

Compatibility Guide

This drive uses a standard 3.5-inch SATA form factor with a SATA 6Gb/s interface, fitting into any compatible desktop or NAS chassis. It is engineered for systems with up to 24 bays, making it ideal for business NAS arrays. The drive requires a standard SATA data cable and a SATA power connector. It works with all major RAID levels (0,1,5,6,10) but check your NAS or RAID controller compatibility. Toshiba lists compatibility with popular NAS brands such as QNAP, Synology, and Asustor.

Product Info

Launched in 2025, the Toshiba N300 PRO 24TB is positioned as a high-end NAS hard drive, suited for enterprise-grade storage needs. It offers a workload rate of 550TB/year, an MTTF of up to 2.5 million hours, and comes with a 5-year limited warranty. The drive is available through Toshiba's official store and major online retailers. Pricing is premium due to the 24TB capacity, but the cost per terabyte is competitive in its class.

Best Use Cases

This drive is ideal for: - IT administrators managing medium to large business NAS systems. The 24TB capacity allows constructing multi-terabyte storage pools with RAID, while the high workload rate ensures reliability under constant write loads. - Professionals in media production or surveillance recording requiring high-capacity, high-frequency data writes. The 550TB/year endurance supports daily writes of ~1.5TB for over three years. - Home or small office users who demand long-term, stable NAS storage. Its enterprise-grade durability outperforms consumer drives for 24/7 operation. ## Alternatives
In the same 24TB NAS drive class, competitors include the Seagate Exos X24 and WD Gold 24TB. Seagate Exos X24 offers similar workload ratings but some models use SMR, which can degrade write performance compared to CMR in the Toshiba. WD Gold 24TB also uses CMR and is highly reliable, but the Toshiba often provides competitive pricing and effective RV vibration damping. However, Toshiba's support ecosystem may be less extensive than Seagate's or WD's.

Things to Consider

This drive is a bare internal HDD; you cannot use it as an external drive without an enclosure. Ensure your NAS or PC has a free SATA port and a compatible power supply. For systems using UEFI/BIOS, verify that they support GPT partitioning to recognize the full 24TB capacity. Not all NAS enclosures officially support 24TB drives, so check the manufacturer's compatibility list. Also, consider whether you truly need 24TB per drive; for smaller workloads, lower-capacity models may offer better value.
