Most NAS devices support typical RAID configurations from RAID1 to RAID5, while more advanced NAS devices support advanced RAID configurations such as RAID 50 and RAID 60. The availability of these options depends on the NAS provider and the available feature set. The disks in a NAS are typically combined using a redundancy solution like a RAID array or a proprietary solution like Synology Hybrid RAID (SHR). Most NAS devices come as multi-device (SSD/HDD) enclosures except for a few consumer-focused NAS devices.

NAS devices can provide simultaneous connectivity to multiple users or PCs/servers without significant performance penalties. It is a file-level data storage solution that provides storage via the network. NAS or Network Attached Storage is by far the most popular storage solution for both consumer and enterprise users. Additionally, DAS has limited expandability, which is limited by the number of connections a host pc can utilize and the number of drives the DAS solution supports. Disadvantages of DASĭAS is not suitable for providing storage connectivity to multiple users or devices due to their directly attached nature and not having network connectivity. They can be cost-effective solutions with limited maintenance requirements depending on the configuration. As the storage is directly attached to a host machine, it can provide the best performance and latency, only subject to the inherent limitations of the connectivity interfaces. Performance is the primary advantage of Direct Attached Storage as the devices are the performance. eSATA (External Serial Advanced Technology Attachment).SATA (Serial Advanced Technology Attachment).Following are some of the connectivity options that can be utilized for Direct Attached Storage devices: DAS devices can consist of multiple hard drives in a single enclosure without any network connectivity. A typical example of a DAS is an external storage device attached to a pc or a server. What is Direct Attached Storage (DAS)?ĭirect attached storage is the simplest storage type: a storage device is directly attached to a host device. In this article, we’ll look at each and help you determine which is best for your use case.

In this post, we will look at the following storage technologies while comparing their features and use cases. The ever-growing need for storage innovations in storage-related technologies has given rise to different storage methods to power consumer and enterprise needs.
