Dobrý den. Lze v NAS QNAP TS-251+ použít rámeček QNAP-QDA-A2AR, osadit 3ks SSD HDD a nastavit disky v RAID5? Nebo je k dispozici pouze RAID0, RAID1 a JBOD podle nastavení switche?

The QNAP QDA-A2AR adapter can accommodate two 2.5" SATA drives in one 3.5" position. It does not require any software driver and can be installed on a Windows, Linux or QNAP NAS computer or workstation. It provides file transfer speeds of up to 6 Gb per second. Supports a variety of RAID configurations. You can use the metal switch to toggle the disk mode and choose the mode that suits you. The adapter offers an individual mode. For a computer that supports SATA port multipliers, you can connect two SATA drives to a single SATA port, allowing you to access each drive independently. In RAID 1 mode, half of the total storage capacity is used to store data and the other half stores a copy of that data. RAID 0 mode distributes data between disks. It guarantees the fastest performance, but does not protect data from disk failure. JBOD mode recognizes all disks as a single drive, allowing maximum storage utilization, but data is not protected.
When using two 2.5" drives, you can create RAID 0 for increased performance or RAID 1 to add data redundancy and provide greater data protection. To handle tasks that require fast data transfer, you can install a high-speed SATA SSD for maximum performance and lower latency. You can also use the QNAP External RAID Manager to allow Windows users to view the status of disks and information about the QNAP QDA-A2AR RAID adapter. You can also easily manage firmware updates using the tool.
The QNAP QDA-A2AR adapter supports hardware RAID, which does not consume CPU resources to maintain optimal NAS performance. It is possible to install one or more QNAP QDA-A2AR adapters in a NAS to make the most of the 3.5" drive bays. The Adapter can accommodate two SSDs to create an SSD volume to enable performance-intensive workflows or work in an efficient tiered storage environment with Qtier. This will lead to an increase in IOPS performance while configuring the SSD cache. You can conveniently check the RAID and disk health information of the QNAP QDA-A2AR adapter through the QTS Storage Manager and Snapshots.
