The storage is presented to the end user as a single shared volume accessible over the Internet through a web-based interface or the accompanying applications for PC, Mac, Android or iOS. The drives of the latter are combined into a single logical unit using the spanning, striping or mirroring technique. The devices are available in both singe-drive (My Cloud Home) and dual-drive options (My Cloud Home Duo). WD My Cloud Home is a line of consumer NAS products designed by Western Digital. RAID sets are not created over the whole disks but over the regions on them of several tens of megabytes, which are then combined in zones, from which the allocation of file system clusters is carried out. BeyondRAID employs a combination of RAID 1 and RAID 5 to achieve single redundancy and a combination of parity and diagonal parity for double redundancy, while the protection algorithm is chosen by BeyondRAID itself on the basis of data availability needs at the given moment. To combine multiple physical disks into single storage and ensure data safety, Drobo utilizes a proprietary RAID-based technology called BeyondRAID. A home-oriented Drobo NAS box applies ext3 and is presented to the operating system as network storage with a single volume, in contrast to professional models, which usually give the possibility to split up the storage into several volumes or Logical Unit Numbers (LUNs). Drobo DAS is normally recognized by the host PC as an ordinary USB drive and is managed by the file system defined by the host computer. A Drobo unit can feature from 4 up to 12 drive bays, in which drives of different capacities, types and spindle speeds can be inserted. The raw content of files and storages can be analyzed and edited directly in the software with a broad set of supplementary tools.Drobo is a series of multi-disk NAS and DAS devices developed by Drobo Inc. A map with defective areas can be generated during imaging or through the conversion of used/free file system space to mask and employed during the recovery procedure. A full or partial image of a disk can also be created with the help of an embedded imaging function with various settings for disk reading and omission of damaged blocks. Operations with drives connected to DeepSpar Disk Imager can be performed via LAN and controlled by the software without the need for any third-party solutions. The software offers an advanced procedure for opening storages with parameters as to their usage and an opportunity to save a sparse image file with the processed data. Moreover, UFS Explorer Professional Recovery features extended possibilities for efficient processing of storage devices, especially ones that demonstrate certain hardware problems. Furthermore, the application allows working with various virtualization systems, like VMware, Hyper-V, VirtualBox, QEMU, XEN and many formats of disk images. The software also supports numerous file systems used in Windows, Linux, macOS and BSD, offering direct access to their content, well as a variety of storage technologies, among which are Windows Dynamic Disks, Storage Spaces and deduplication, Apple Software RAID, Core Storage and Time Machine, Linux mdadm and LVM with Thin Provisioning. The integrated decryption algorithms make it possible to open volumes encrypted with BitLocker, LUKS, FileVault 2 and APFS without having to unlock them in the operating system. UFS Explorer Professional Recovery is an expert-level software instrument created to address highly complicated data recovery challenges.Īlong with linear electronic media, like hard disks, thumb drives and memory cards, the program handles RAID-based storages with various layouts, including standard, nested, custom and specific configurations – Drobo BeyondRAID, Synology Hybrid RAID, Btrfs-RAID and ZFS RAID-Z.
