Install two 2.5" SATA drives into a 3.5" drive bay and get increased performance or data redundancy with RAID. This unique dual-bay adapter enclosure gives you an easy and cost-effective way to upgrade legacy systems such as desktop PCs and servers, by allowing you to install two 2.5" solid-state drives or hard drives into a single 3.5" drive bay.

Upgrade your system performance

The adapter enclosure let you install newer, higher performing drives such as SSDs into legacy systems that may only support 3.5" hard drives. The enclosure provides a cost-efficient way for companies and organizations to enhance storage performance and reliability without expensive upgrades to core IT systems. It's also ideal for system administrators and integrators who want to build a system or upgrade a system with limited SATA interfaces to take advantage of the increased drive performance of 2.5" SSDs or increased capacity with support for two drives.

The adapter enclosure allows you to install two 2.5" SATA drives into an internal or external 3.5-inch bay, such as a drive drawer caddy or tray, or 3.5" drive enclosure. To utilize the full speed potential of your SATA III hard drives, the drive converter supports SATA III for transfer speeds up to 6 Gbps. Suitable for drives with a height of up to 15mm, virtually any 2.5" SATA hard drive can be made to look and function like a 3.5" hard drive.

Enhanced performance and data redundancy with RAID

The adapter enclosure is equipped with hardware RAID to provide improved performance and data redundancy. The enclosure supports both RAID 0 and RAID 1 as well as Spanning, and JBOD, and allows you to choose your preferred backup mode by simply adjusting the RAID setting switch.

The RAID 1 functionality is ideal in a hot swapping server environment, providing a level of security and reliability to your data through data redundancy. With RAID 0 support, you can combine the storage capacity of the two hard drives and achieve faster read and write speeds.

Easy and flexible installation

The adapter enclosure can be installed easily into a desktop PC or server. It offers flexible use in hot swap bays or in a more fixed, permanent installation in a 3.5" hard drive mounting bay with standard mounting holes. Once installed, you simply slide two 2.5" HDDs/SDDs into the adapter enclosure, with no tools required. The aluminum housing protects installed drives in a durable enclosure.

The 35SAT225S3R is backed by a 2-year warranty and free lifetime technical support.
