Hot swap with ease by installing four SSDs/HDDs into one 5.25in bay. Now it's easy to drive share & enhance the storage capabilities of your server or PC. This mobile rack backplane lets you install four 2.5in SATA or SAS solid-state or hard disk drives into a single 5.25in bay & quickly hot swap them between systems. It's ideal for systems integrators & administrators who are looking for flexible management of their data storage. The mobile rack backplane is engineered to protect your valuable data & provide reliable performance. The aluminum housing is designed for enhanced heat dissipation, while two 40mm fans improve air flow to minimize heat build-up & ensure optimum operating temperature. You can lock the removable steel trays in place, providing an enhanced level of drive protection. The backplane can be mounted either vertically or horizontally, for error-free tray insertion & maximum compatibility with servers or desktop computers. The Non-Scratch SATA (NSS) connector provides a high 50, 000+ insertion rating, your assurance of long-lasting performance of both the drives & the bay. Many fast-paced work environments require drives to be removed regularly. Hot swap between systems quickly, without shutting down, with the convenient backplane. The included trays are interchangeable, working with both the 4-bay backplane & the single-bay backplane (SATSASBP125) so you can hot swap between systems for easy file access. Designed for versatile use, the backplane supports an extensive range of both SATA or SAS based HDDs & SSDs, from 5 to 15mm in height. To maximize the performance of your drives, the mobile rack supports SAS II & SATA III performance for transfer speeds up to 6 Gbps when paired with a compatible controller. The backplane also works with your preferred RAID controller or Hyper Duo controller to produce a high-performance or redundant storage solution.
