QNAP Releases QTS 4.4.2, Enhancing System Security and Supporting a Wider Range of USB/SATA Expansion Solutions

April 03, 2020 By BlueAlly

Taipei, Taiwan, April 3, 2020 - QNAP® Systems, Inc. (QNAP) today released the QTS 4.4.2 NAS operating system. Featuring numerous improvements and enhancements from the previous version, QTS 4.4.2 also enhances system security and storage scalability. The default password of the NAS has been changed to the first MAC address of the NAS for greater NAS security. QTS 4.4.2 also supports QNAP’s new expansion units - the high-speed TL SATA JBOD series that supports multi-lane SATA 6Gb/s transfer, and the convenient-to-use TL USB JBOD series with USB 3.2 Gen 2 10Gb/s connectivity. Starting from today, QNAP NAS users will receive QTS 4.4.2 update.

While QTS 4.4.1 focused on cloud storage integration and cloud gateway services, QTS 4.4.2 strengthens storage expandability with physical JBOD units for satisfying file storage and backup needs. The new TL SATA JBOD and TL USB JBOD series not only work with QNAP NAS, but also support computers and servers with the QNAP JBOD Manager companion utility.


The TL SATA JBOD series includes models with tower (4-bay TL-D400S, 8-bay TL-D800S, 16-bay TL-D1600S) and rackmount (4-bay TL-R400S, 12-bay TL-R1200S-RP) form factors that support multi-lane SATA 6Gb/s transfer. The SATA JBOD series is designed with each SATA lane directly connected to individual SATA drives, greatly enhancing the expansion unit performance to provide a high-speed and economical storage expansion solution. The JBOD series is ready for use with bundled QXP expansion cards and cables. The QXP expansion card can be installed into the PCIe slot of a QNAP NAS or Windows®/ Linux® (Ubuntu®) PC to add multiple SATA 6Gb/s connectivity, and a single SFF-8088 cable provides up to 24Gb/s (4 x SATA 6Gb/s) transfer speed. Transfer speeds between the host and JBOD can be driven up to 64Gb/s when using multiple cables.
