This article covers ORICO HDD ケース 3.5インチ USB 3.0.

Overview

The ORICO DDL35-U3 is a hard drive enclosure designed to turn 3.5-inch and 2.5-inch SATA HDDs or SSDs into external storage. It supports drives up to 20TB and connects via USB 3.0 with a theoretical transfer rate of 5Gbps. With UASP (USB Attached SCSI Protocol) support, it can achieve up to 70% faster read/write speeds compared to standard USB 3.0 when used with a compatible host. Its construction combines ABS plastic with a metal shell for improved heat dissipation and drop resistance. The tool-less design lets you install a drive in seconds without any screws or drivers. A dedicated 12V/2A power adapter ensures stable power delivery, and an auto-sleep feature activates after 10 minutes of inactivity to save energy.

Connectivity & Compatibility

The enclosure uses a USB 3.0 Type-B interface (backward compatible with USB 2.0/1.1) and comes with a 1-meter USB 3.0 cable. It works with Windows, macOS, Linux, iPad OS (via Thunderbolt), Android, and game consoles such as PS4 and PS5. It is also compatible with smart TVs and smart routers that support external USB storage. Internally, the DDL35-U3 supports both 3.5-inch and 2.5-inch SATA III (6Gbps) drives. It has been tested with drives from Western Digital, Seagate, Toshiba, Samsung, Crucial, and SanDisk. Hot-swap is supported, so you can swap drives without powering down the enclosure.

Product Info

The ORICO DDL35-U3 sits in the entry-level to mid-range segment of external hard drive enclosures. Its price is around ¥2,500 (approximately $17 USD), making it an affordable solution for repurposing internal drives. The warranty is typically one year (check your region). The package includes the enclosure, a USB 3.0 cable, a 12V/2A power adapter, and a user manual. Compared to premium Thunderbolt or NAS enclosures, the DDL35-U3 offers modest transfer speeds, but it is perfectly adequate for backups, media storage, and general file archiving. It is a cost-effective way to add external storage without buying a new dedicated external drive.

Best Use Cases

Repurposing old internal HDDs: If you have a 3.5-inch SATA drive lying around, this enclosure gives it a second life as an external backup or media drive. Ideal for budget-conscious users who want to maximize existing hardware. PS4/PS5 storage expansion: Gamers can connect the enclosure to their console via USB to add extra storage for game installs and captures. It is a simple plug-and-play solution without opening the console. Affordable backup solution: For users who need multiple backup drives (e.g., for off-site or versioned backups), the low price per enclosure makes it practical to have several units with different drives. Tool-free drive swapping: The slide-and-lock mechanism allows quick drive changes without tools. This is handy for users who frequently rotate drives for different projects or data sets. However, this enclosure is not suitable for high-speed workflows like 4K video editing (where NVMe or Thunderbolt is preferred) or for portable use with 2.5-inch drives that could run on bus power alone. If you need maximum portability, consider a USB-powered 2.5-inch enclosure instead.
