SSD Technologies

QNAP SSD features accelerate NAS performance and improve your work efficiency, with a small investment.

SSD NAS is not for the rich anymore

Solid-state drive (SSD) prices continue to fall and are becoming nearer in price to hard drives (HDD). QNAP NAS, optimized with QNAP’s SSD technologies, provides SSD-aware storage solutions that enhances the natural performance benefits of SSD while ensuring reliably fast access to data!

Four SSD Features

Expand NAS SSD Capacity with QM2 PCIe Expansion Cards

Installing QNAP’s QM2 series PCIe cards can boost performance by adding M.2 SSD slots. It does not occupy any 3.5-inch drive bays, and allows you to maximize the NAS storage capacity and performance.

  • Add M.2 Slots

    • M.2 PCIe NVMe SSDs
    • M.2 SATA SSDs
  • Add M.2 Slots and Network Ports

    • M.2 PCIe NVMe SSDs
    • 2.5 Gb Ethernet ports
    • 10 Gb Ethernet ports

Selecting SSDs on The Market

To find a suitable SSD, you must first have an understanding of the different types of SSD NAND Flash and SSD interfaces. Secondly, you need to make the selection based on your NAS workload. To simplify your SSD selection process, please see the two tables below that sum up the different types of SSD NAND Flash and SSD interface features for different application scenarios.

NAND Flash Multi-Level Cell (MLC) Triple Level Cell (TLC) Quad Level Cell (QLC)

Is SSD Cache or Qtier™ More Suitable?

QNAP has compiled some of the major differences between SSD cache and Qtier™ and their application scenarios in the following lists to make selection easier:

  • SSD Cache - Boost real-time read/write performance

    Suitable for intensive read/write of a huge number of small files, such as virtualization, and teamwork.

    SSD cache can be disabled or adjusted for read-only and write-only mode depending on different application scenarios to meet your needs at any time.

  • Qtier™ - Fully utilize the SSD capacity

    Suitable for database servers or applications with cold or hot access pattern for effective tiering.

    Qtier™ can be applied to databases when paired with Qtier IO-aware.

QNAP NAS X SSD Enables Multiple Configurations for Maximizing NAS Performance!

SSD can always optimize your QNAP NAS performance, whether with SSD extra over-provisioning, cache, or Qtier™ Auto Tiering Storage. The table below shows multiple configurations for you to maximize NAS performance.

Scenario File Server Web, Application, Virtualization Server Video Editing Surveillance, Backup, Log Server Business-Critical Database
SSD Configuration Qtier Qtier SSD RAID SSD Write- Only Cache SSD RAID
SSD RAID RAID 6 RAID 10 RAID 5 RAID 10 RAID 10
SSD Over-provisioning space 10% 20% 20% 30% 30%
