SSD Cache

The recently updated ADM features an updated Linux Kernel and additional performance enhancements. The Lockerstor series introduce M.2 PCIe NVMe SSD caching increasing performance.

1. Lockerstor NVMe SSD caching increases performance by up to 60%.

2. Lockerstor NVMe SSD caching is faster than if all bays were filled with SATA SSDs while remaining cheaper.

With dual 10-Gigabit Ethernet, bottlenecks on NVMe SSDs have been lifted, making the Lockerstor one of the fastest NAS devices ever.

Eight Bays with Flexible M.2 SSD Caching

The AS6508T is a cost-effective large capacity NAS designed for enterprise environments.The AS6508T supports online capacity expansion, allowing for the flexible purchase of enterprise storage equipment. When your budget and storage requirements are smaller, you can purchase a smaller number of hard disks. Additional disks can be purchased as your storage requirements grow. Combined with ASUSTOR’s MyArchive storage technology, this allows you to effectively achieve unlimited storage.

Powerful and high efficient cooling design

The Lockerstor utilizes PWM fans with smart speed controls and heatsinks with push-pin mounting to achieve optimal airflow, enhancing stability and maintaining high performance even under high loads.

The Lockerstor’s improved design features improved heatsinks that are taller than previous models to ensure even more efficient cooling and heat dissipation.

Easily upgrade memory by opening the chassis.

The Lockerstor comes with 8 Gigabytes of DDR4 RAM and can be upgraded up to 32GB. DDR4 RAM provides up to 30% greater performance than DDR3 while also lowering energy requirements by 40%.

24/7 Reliability and Durability

All ASUSTOR NAS are designed for and are suitable for 24/7 use. ASUSTOR NAS devices have also undergone rigorous tests, such as drop tests and burn tests to test durability in extreme conditions. Heatsinks were added to sensitive components to dissipate heat, helping to maintain the longevity of the device.

Protected From the Inside and Out

Protect your data from loss, damage and attacks with the AS5202T. An ASUSTOR NAS is better protected by running the Linux-based ADM, employing a built-in firewall, ClamAV Antivirus, MyArchive and ADM’s various backup tools help protect ransomware even better.

Wake Up From Anywhere

The Lockerstor 8 and 10 feature Wake on WAN technology. No specialized equipment or settings are needed to wake the NAS. Simply use ASUSTOR’s wide variety of mobile apps, including but not limited to AiMaster, AiMusic, AiVideos and AiData to turn the NAS on or off remotely. Wake on WAN helps protect data by keeping the NAS powered off when not in use; thereby helping to prevent attacks, protects data integrity by remaining powered off during power failures and Wake on WAN also saves electricity, making for an even more efficient NAS.

Protected From Ransomware

The Lockerstor comes with the most up-to-date version of ADM to help protect against ransomware attacks. With Snapshot Center and Btrfs providing efficient snapshots to easily restore lost data. Other security features found on the Lockerstor are the ability to create one or more replacement administrator accounts, a firewall by ADM Defender that features black and white lists and the ability to change default ports, disable SSH and Terminal to prevent remote attacks. MyArchive cold storage hard drive security can also be increased by implementing AES 256bit encryption.

Comprehensive Backup Solutions

ASUSTOR’s comprehensive backup solution provides more than twelve backup options, including, but not limited to Amazon S3, Dropbox, Google Drive, and Onedrive. ASUSTOR Backup Plan for Windows as well as Time Machine for macOS provide easy backups for desktop and laptops while MyArchive removable hard drives provide long term storage. Btrfs is now supported and with Snapshot Center, can take snapshots of your information in the event of unintentional modification. Restore previous versions easily with Snapshot Center.

Snapshot Center supports up to 256 snapshots of a volume and can be done every five minutes, creating a backup that can be restored easily if data is damaged or lost.

File Editing and Project Collaboration

NextCloud and OnlyOffice make collaborating on projects easier than ever by creating a cloud office suite for offices to work on documents, spreadsheets, presentations and more.

Exclusive MyArchive Cold Backup Technology
 Unlimited Capacity Expansion

MyArchive cold backup technology turns NAS hard disks into removable storage archives. Directly insert a MyArchive hard disk into the NAS to easily access, backup and share terabytes of content.

Portainer – Easy Docker Deployments
