What is a Nas Device: Netword Attached Storage
What is the speed of a network adapter available on a NAS device? The speed is typically one gigabit Ethernet connection but this can be changed to multiple gigabit, 10 gigabit, fiber optic by adding a pci-e network card
What is the capacity range? The capacity range again varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and addon hard drive controller cards there is hardly a limit on size. A board with 6 sata ports can be replicated (1 to 5 port) allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage.
Is there any fault tolerance (Such as RAID) built into a NAS Device? As far as fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 has been touted as one of the best setups since more drives can fail at one time without data loss. All of those features can be used on typical NAS devices. http://www.tomshardware.com/forum/275439-32-devices
Are management Features available Management software ideally provides interoperability with a variety of NAS devices from different vendors and can automate many of the routine management tasks that would otherwise demand manual attention. http://searchstorage.techtarget.com/tutorial/NAS-management-software-specifications A user would use this for more mobility and larger stoage, as well as stream media share files and programs with other pc’s on the same
