This article covers ADATA SD820 外付けソリッドステートドライブ.
Overview
The ADATA SD820 2000GB is a portable external SSD offering 2TB of storage capacity in a compact, travel-friendly form factor. It connects via USB, making it easy to add extra space to any PC, laptop, or console. The blue finish gives it a distinctive look that stands out on any desk. Whether you need a backup drive, extra storage for games, or a fast scratch disk for creative work, the SD820 delivers reliable performance at a reasonable price point.
Compatibility Guide
Since this is a USB-connected external SSD, compatibility is broad. It works with any device that has a USB port, including Windows PCs, Macs, Linux systems, PlayStation 4/5, and Xbox consoles. The drive uses a 2.5-inch form factor but is housed in an external enclosure, so internal drive bays are not required. Power is supplied over USB (bus-powered), so no separate power adapter is needed. For best performance, use a USB 3.0 or higher port.
Product Info
The ADATA SD820 2000GB is a mid-range portable SSD aimed at everyday users who need reliable external storage. It features a 2TB capacity and uses a USB interface to achieve decent transfer speeds. The market positioning is entry-to-mid, offering good value for money. Warranty details vary by region; check the official page for specifics. Its main strength is simplicity: plug and play without driver installation.
Best Use Cases
Data backup for general users: Ideal for backing up photos, documents, and other important files. No setup required – just plug into a USB port and drag-and-drop. Who should not choose it?* Users needing ultra-fast NVMe speeds for heavy workloads.
Game storage expansion: Connect to a PS5 or Xbox Series X|S to install and play older-generation games, or use as extra storage for PC games. Who should not choose it?* Those who need to play native PS5 games directly from external storage (not supported).
Creative work on laptops: Videographers and photographers can use it as a portable working drive for editing projects. USB 3.2 Gen2 provides adequate throughput for most workflows. Who should not choose it?* Professionals who require sustained high-speed read/write for 4K/8K real-time editing.
Things to Consider
This drive relies on USB connectivity, so transfer speeds will be limited by the USB version. USB 2.0 will dramatically reduce performance – always use USB 3.0 or better. The internal SSD is likely SATA-based, not NVMe, so it won't match internal NVMe drive speeds for sequential transfers. Color options are limited to blue. Additionally, while the 2TB capacity is generous, heavy users may find it fills up quickly.
FAQ
Q: Can I use this SSD with my PlayStation 5?
A: Yes, it works as external storage. You can store and play PS4 games from it, but PS5 games cannot be played directly from an external drive – you would need to transfer them back to the internal SSD.
Q: How fast is the transfer speed?
A: Official specs are not listed in our sources, but with USB 3.2 Gen2, theoretical max is 10Gbps (~1250MB/s). Real-world speeds depend on the file type and host controller. For typical backups, it is more than adequate.
Q: Is there any software included for backup or encryption?
A: ADATA often includes a free download for backup software, but check the product page for the specific package. The SD820 may come with a basic backup utility.
