How to choose the best NAS, according to QNAP

When you are about to choose a NAS it should be kept in mind that the various devices that can be purchased on the market are very different from each other and it is not in fact possible to recommend a single model capable of satisfying all needs. The best NAS it is the one that manages to adapt to the needs of the individual user, the professional, the company: furthermore, the characteristics and prices of each device obviously vary from one model to another. In short, as there is no suit for all seasons, it is not possible to suggest a NAS for every kind of need.

Those who choose a NAS do so primarily to manage i backup effectively, have a tool capable of managing copies of your data in a secure way, capable of offering important storage capacitywhich is expandable over time and which perhaps also allows data to be transferred to backup locations offsiteto apply the 3-2-1 backup rule.

Let’s take QNAP NAS as an example: these devices have long been not only tools for data backups in RAID but have turned into real servers designed to perform the most diverse tasks. On the backup side, a QNAP NAS can perform all types of backup jobs: they are suitable for creating backup copies of servers, workstations, PCs, macOS system, virtual machines, containers, cloud services, file servers, SaaS platforms using protocols RTRR, rsync, FTP, CIFS/SMB and so on.

I NAS QNAP their operation is based on a real operating system that already offers various pre-installed applications and allows the loading of other tools through the rich App Center.

Storage professionals with QNAP

With this article we continue with the appointments dedicated to those who wish to benefit from useful advice to innovate their own business infrastructure choosing the right mix of hardware devices, software solutions and technologies.
The goal is to help professionals and companies to promote the digital transition increasing the productivity and competitiveness of the company.

The entire editorial project developed in collaboration with QNAP focuses on the importance of data and on the activities that must be implemented to preserve its value. THE video that we offer as a corollary to each article, are “pills” that in about 5 minutes tell the main needs of professionals and some PMI in the field of data management by suggesting the best strategies to face today’s challenges and become “Storage professionals with QNAP“.

Differences between NAS QNAP based on QTS and QuTS hero

QNAP offers two operating systems different for its NAS: QTS and QuTS hero: this is already a feature that clearly indicates which “audience” each product is aimed at. QuTS hero-based NAS are targeted at one user enterprise while the others are offered to individuals ranging from private users to professionals and SMEs.

QuTS hero uses the file system ZFS and is designed to offer greater reliability and protection against data corruption. Users who choose NAS based on QuTS hero have “folders” available on which, for example, data compression and deduplication can be activated. With ZFS you can indeed manage them too hybrid configurations in terms of storage combining hard drives and SSD drives of different sizes; moreover, you can benefit from capacity up to 5 Petabytes for each shared folder. QuTS hero offers advanced redundancy and fault tolerance features that arise from the unique characteristics of ZFS.

The QTS-QuTS hero classification certainly offers a good reading key for choose the best NAS for your needs but it is certainly not a sufficient approach to select the most suitable model.

Choose the NAS with the QNAP selector

For example, some QNAP NAS models are more suitable for virtualizationothers for video editing, still others to fill the role of media server. In general, some NAS are better suited for some tasks while others are better for handling different kinds of tasks. QNAP NAS Selector is a tool that we welcome you to use to get some practical tips about device models that best meet your needs.

Choose the best QNAP NAS

QNAP’s web application helps you choose the best NAS from the most suitable ones for your business video surveillance, for multimedia needs (including media server), for data archiving and backup. After indicating the number of concurrent connections that the NAS is expected to support and the data volume to manage estimated, the QNAP selector shows a series of indications of the models from which you can choose. It is not essential to specify the right away RAID configuration chosen: as we will explain further on, in fact, it goes hand in hand with the amount and type of data to be managed and is a function of the level of performance to be obtained during the data transfer phase.

QNAP NAS Best Choice - Web Selector

We really think the boxes are very useful Focus placed in the left column of the QNAP NAS selector: by activating the various selection options, for example, only the NAS that offer the best data transfer rate or those more suitable for video transcoding (we’ll talk about it later), to optimize team collaboration, to improve the performance of virtual machines and applications virtual desktop.

NAS that stand out in terms of capacity and throughput are for example more suitable for the video editing; those with limited video transcoding skills are not well suited to fulfill the role of media server Plex.

Throughput e IOPS

Throughput e IOPS (Input/Output Operations Per Second) are two different metrics used to measure the performance of the devices storage such as hard drives, SSDs and other data storage systems.

Il throughput, expressed in MB/s or Gbps, refers to the amount of data that can be transmitted through a storage device in a given period of time. Indicates the speed of data transfer and can be affected by factors such as bandwidth of the connection interface (ie network card) and the read and write speed of the storage device.

The IOPS, on the other hand, measure the number of input/output operations that a storage device can perform every second: it expresses how fast a device can handle read and write operations. It is a data widely used to evaluate the speed of access to small blocks of data, such as databases or I/O-intensive applications. In the case of applications of virtualizationWith a few exceptions, high IOPS matters more than throughput.

QNAP NAS hard drive and SSD performance

Moving to the section Storage and snapshots of any QNAP NAS then clicking on Storage, Disks/VJBODit is possible to check the type of unit installed in the device and possibly start a performance tests for each of them.

The network card installed in the NAS and the local infrastructure are essential to ensure fast data transfers: it is useless to invest in high-performance SSD units and in the creation of RAID groups composed of a good number of hard drives if it is not possible to move data on the local network or from to the LAN at least 1 Gbps. Using proper Ethernet cables, of router e switch capable of handling a large bandwidth is essential not to introduce bottlenecks that bring down the performance of any NAS.

Transcoding o transcodifica video

Is called transcoding or video transcoding is the process of conversion of a media file from one format to another, usually to adapt it to the playback specifications of a particular device or application. During transcoding, the original file is decoded, decompressed, and then re-encoded into the new one Format required.

In the context of NAS servers, transcoding is particularly important because it allows the smooth playback Of multimedia content on devices with features that are also very different from each other. For example, a high resolution videos with a particular format it may not be playable on a device that does not support that format or suffers from obvious limitations in terms of computing power.

Thanks to transcoding it is possible to adapt it streaming video to the client device and the conditions of the network you are using: for example, with the aim of reducing the amount of bandwidth busy, you can reduce the resolution or lower the bitrate. In this way the playback of content multimedia can run smoothly even when the conditions of the network in use are not optimal.

Transcoding is obviously an excellent feature that however requires a decent one computational power to be managed, via a dedicated GPU, an integrated GPU or just using…
