Yes so really although things like firware errors do add to the risks its only minimal in comparison to the effects we protect against everyday. I contract for small businesses and always like to implement at least 2 onsite backups and 1 remote backup at all my clients. All backups are raid 1 or raid 5.<br />
Thanks for the comments guys, I think I will continue using the same drives as I had been.

Ok so I have always made my NAS Boxes by initially filling the RAIDs with the exact make and model drives as I thought this would be the most optimal combination. But I was just thinking of this... What If you created a RAID with all the same make and model or even batch of HDDs and these respective drives were shipped with a bad firmware or some physical problem and due to their similarities they all failed within moments of one another?<br />
What is everyones thoughts on this? Should you infact create a NAS solution by mixing the drives to dodge common faults or are there other more stronger reasons to keep your NAS box filled with the exact drives?

Mixed drive NAS

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
