HighPoints SSD6444 Series Enclosures are the industry's most compact external PCIe Gen3 NVMe RAID Solutions. The flexible, high-performance hardware architecture leverages intelligent PCIe switch technology and PCIe Gen3 x16 host connectivity to allocate x4 lanes of dedicated bandwidth to each NVMe SSD. This enables each enclosure to deliver up to 14,000MB/s of transfer performance using just 4 NVMe SSDs!

Robust, Ultra-Quiet Cooling Solution

SSD6444 Series RAID Enclosures actively combat the threat of  thermal throttling and works to ensure critical storage can remain online. The robust, aluminum chassis is equipped with a powerful, low-decibel cooling fan and ventilated drive bays, and features a comprehensive real-time monitoring system that incorporates full fan control with LED indication, audible alarms and thresholds that can be customized to correspond with your choice of NVMe SSDs. The advanced cooling system and sensor suite are designed to work in conjunction with the HighPoint WebGUI and CLI software management suites. SHI (Storage Health Inspector) enables administrators to monitor the temperature of each NVMe SSD in real time, and configure warning thresholds to correspond with each make & model.

Ultra-Compact Form Factor

At less than 5 inches tall, and only 6 inches wide, the SSD6444 & SSD6444A is one of the most compact 4-bay storage enclosures in today’s marketplace. The vertically aligned 2.5” drive trays allow for a marked reduction in chassis height and mass, which ideal for applications that require a portable, easily serviced high-speed mass storage solution.

Comprehensive Management & Monitoring Suite

SSD6444 Series enclosures include a comprehensive suite of graphical and command-line based management and monitoring tools suitable for administrators of any experience level. The WebGUI is a simple, intuitive Web-based graphical user interface. It is equipped with Wizard-like quick configuration menus as well as a suite of advanced tools for expert administrators. The CLI (Command Line Interface) is ideal for seasoned administrators or platforms that do not utilize graphical operating systems .

SHI (Storage Health Inspector): instantly check the status of NVMe media in real-time. SHI utilizes SMART technology to log & report the physical characteristics of each SSD, such as temperature, voltage & TBW (Total Bytes Written).

Intelligent 1-Click Self-Diagnostic & Logging Solution: HighPoint’s WebGUI includes a host of automated diagnostic tools designed to streamline the troubleshooting process, even for novice administrators. The Diagnostic tab enables the interface to gather all necessary hardware, software and storage configuration data and compile it into a single file, which can be transmitted directly to our FAE Team via our Online.
