This article covers 東芝 8TB N300 NAS 3.5インチ SATA 内蔵ハードドライブ 24時間365日稼働 1-8ベイシステム対応 256MBキャッシュ 180TB.

Overview

The Toshiba N300 series is a 3.5-inch internal hard drive designed specifically for NAS (Network Attached Storage) environments. The HDWG480UZSVA model offers 8TB of storage capacity, spinning at 7200RPM with a 256MB cache buffer, and is engineered for 24/7 continuous operation across 1 to 8 bay NAS systems. Leveraging Toshiba's Dynamic Cache Technology and Stable Platter Technology, this drive delivers reliable real-time performance with a workload rating of 180TB per year. It's an excellent choice for home users, home offices, and small businesses seeking dependable bulk storage. Positioned in the entry-to-mid-range NAS HDD segment, the N300 competes directly with Seagate IronWolf and WD Red series, offering a balance of affordability and enterprise-grade reliability.

Compatibility Guide

This drive uses a standard SATA 6Gbps interface and fits any 3.5-inch drive bay. It is compatible with most consumer and prosumer NAS enclosures from brands like QNAP, Synology, ASUSTOR, and others supporting 1 to 8 bays. It can also be installed in a desktop PC as internal storage, though its design is optimized for 24/7 NAS operation rather than occasional desktop use.

Product Info

The Toshiba N300 8TB (HDWG480UZSVA) was released around 2021 and carries a 3-year manufacturer warranty. Pricing typically falls in the ¥50,000–¥55,000 range depending on the retailer and market conditions. It occupies the mid-range tier in the NAS HDD market, offering 24/7 reliability and a 180TB/year workload rating at a more accessible price point than enterprise-class drives.

Best Use Cases

Home NAS users: Ideal for building a centralized backup solution for family photos, videos, and documents. 8TB provides ample space for years of data. Small office file servers: Suitable for RAID arrays in shared storage environments. The 180TB/year workload rating handles daily business file operations reliably. * Media server builders: Perfect for Plex or Jellyfin servers where large media libraries need to be stored and streamed. 7200RPM speed supports multiple simultaneous streams.

Things to Consider

This drive may use SMR (Shingled Magnetic Recording) technology rather than CMR. SMR can exhibit reduced write performance under sustained heavy write loads, so it's less ideal for applications involving frequent large file writes or database transactions. At 8TB, capacity is generous for personal use but may be insufficient for 4K video editing workflows or large-scale data hoarding. Competitors like Seagate IronWolf 8TB (ST8000VN004) and WD Red Plus 8TB (WD80EFZZ) offer CMR alternatives worth comparing. When used in a desktop PC, be aware that NAS-optimized drives can be slightly noisier and produce more vibration than standard desktop HDDs during operation.
