Use two M.2 SATA SSDs in a single 2.5-inch SATA drive bay with RAID support for PC and NAS
The QDA-A2MAR can accommodate two M.2 SATA SSDs within a single 2.5-inch SATA drive bay. No software driver is required for the QDA-A2MAR, and it can be installed in a PC/workstation (Windows®, Linux®) or QNAP NAS to flexibly add high-performance M.2 SATA SSDs with RAID configurations to meet various storage needs. Use two M.2 2280 SATA SSDs in a single 2.5-inch drive bay. (M.2 SSDs sold separately) Up to 6 Gb/s file transfer speeds. Can be the primary bootable device containing for PCs. Choose a hardware RAID group with the disk mode switch. Supports various RAID levels The QDA-A2MAR supports a variety of RAID configurations. Depending on your requirements, you can use the bundled metal pin as disk mode switch tool to select your ideal RAID mode: Individual, JBOD, RAID 0, or RAID 1. Windows® users can use the QNAP External RAID Manager utility to view the RAID group status and disk health information. Individual Mode A PC that supports SATA port multipliers can connect two SATA drives to a single SATA port, allowing you to independently access each disk as separate storage space. RAID 1 Mode (Default) Half of the total storage capacity is used to store data, and the other half keeps a copy of this data. This provides high data protection at the cost of only being able to use half the installed storage space. RAID 0 Mode Data is split amongst the drives. RAID 0 provides the fastest performance but does not protect data from drive failure. JBOD Mode All the drives are recognized as a single drive. This allows maximal storage utilization but provides no data protection. Install in a PC/workstation for higher performance or data protection When using two M.2 SSDs instead of a single 2.5-inch drive in a PC/workstation (Windows® or Linux®) you can create a RAID 0 for enhanced performance, or RAID 1 to add data redundancy for greater data protection. The M.2 SSDs also help achieve maximized performance and lower latency, ideal for on-the-fly video editing and server-grade applications. External RAID Manager for Windows users The QNAP External RAID Manager utility allows Windows® users to view the drive status and RAID information of the QDA-A2MAR. Firmware updates for the QDA-A2MAR can also be managed with the External RAID Manager utility. Install in QNAP NAS for efficient storage or SSD caching The QDA-A2MAR supports hardware RAID that will not consume CPU resources to help sustain optimal NAS performance. You can install one or more QDA-A2MAR in a NAS to maximize the storage utilization of available 2.5-inch drive bays. The QDA-A2MAR can accommodate two M.2 SSDs to create an SSD volume for performance- demanding workflows or work in an efficient tiered-storage environment with Qtier. It can also boost IOPS performance when configuring SSD caching. RAID information and disk health of the QDA-A2MAR can be monitored through the QTS Storage & Snapshots Manager. |
