Should I acquire matching disk drives for a NAS RAID 1 array?
I'm intending to acquire a NAS (network affixed storage space) box and also I've selected the Synology DS209. I intend to set up a RAID 1 array and also I'm asking yourself if I need to acquire a coordinating set of disk drives or if it would certainly be far better to purchase from various suppliers. I'm worried that a coordinating set would certainly be more probable to fall short at the very same time.
Go in advance and also purchase from the very same supplier, the opportunity that they would certainly fall short at the very same time even if of that is very not likely. There is additionally a threat that of the drives is slower, suggesting that the faster drive will certainly need to adjust to the slower one.
A basic regulation - of - thumb is to have matching disks in the array. The features of each manufacture will certainly vary, so the extra comparable the disks, the much less like the RAID controller will certainly need to manage information corruption. That claimed, you do not have to make use of matched disks. As an example, see to it you change an unsuccessful disk with an additional the very same dimension or bigger.
I would not be worried about 2 drives from the very same supplier passing away at the very same time. The probabilities of that taking place are significant - - possibly equivalent to that of 2 drives from various suppliers passing away at the very same time.
Currently, if you are bothered with shielding your information, please see to it that you do not only rely upon your RAID1 array. It is not a back-up remedy! See to it you backup your vital information, take it offline, and also take it offsite.
