As photographers or videographers and with the increasing size of multimedia content, we always need more storage space for our files, as well as backup options for all our data. This article is about the perfect Server NAS for Photographers and Videographers. Surely many of us are afraid of losing this data and if you are not, you should be. In this modern digital world, having a robust and reliable back-up system is always an advantage, especially when our data has a commercial purpose. For this reason, I recommend that you consider a NAS (network-attached storage) device.
If we work especially with high-quality digital media such as RAW files for photography or 4k and 8K for video in our professional and recreational activity (from home or office), the performance and flexibility of a server NAS is what you need.
The beauty of a Server NAS is that it is more than just a backup drive, it is actually your own smart computer that can potentially open up a wide range of opportunities for you and make digital life easier (and often cheaper).
What is Server NAS?
For those of you not familiar with NAS devices at all, I am going to quickly break down their basic functionality below. NAS units are made up of storage bays that allow you to easily swap Hard Drives or Solid State Drives. They also have their own Processor and RAM (Random Access Memory) and dedicated operating system. Server NAS is designed to be connected to a network even if your “network” just consists of one computer without any switch or other network devices. So while your external hard drive can only be connected to one computer, a NAS unit can be connected to the whole network of computers with multiple users and separate access permissions. In addition, you can set up your server NAS to be accessible anywhere in the world via the internet (your own personal cloud). You can think of a NAS device as a separate computer with or without a screen.
NAS devices can use multiple storage drives and thus can have very large storage capacities. Previously NAS drives were simple appliances that could just store and distribute data, but with recent hardware and software developments, many of these devices can now serve as Cloud Storage, Media Server, Email Server, VPN Server, and much, much more. Plus they can do all of this with redundant backup configuration, so when one or more (depending on configuration) drives fail (and they will), all your data is still intact.
When the NAS is connected to the internet, you can easily access all your stored data anywhere in the world. Functionality and price of NAS units can vary greatly on their brand and configuration, but you can always start with the budget model and expand to a more advanced system if you decide that Server NAS works for you.
Please note that while NAS units are excellent solutions for backup it should not be the only way you save your files. We always recommend using various backup methods. These should include on-site and off-site solutions. Some of these NAS manufacturers offer bi-directional auto-backup between NAS units so that you can have similar boxes set up in separate locations and have them automatically sync data between each other. This way if disaster strikes at one location the other unit will still have your data.
Features to look in a Server NAS for Photographers and Videographers
The market is oversaturated with brands that offer numerous models of NAS units and it can be very confusing for a new user. Which features are essential? Of course, the priority of these features would depend on the function you want your NAS device to serve, so I am going to focus on items that a photographer and videographer like myself would most likely look for.
- Drive Bays: The first question you need to answer is how many storage drives will be used in your Server NAS. A typical small business NAS configuration can range from 2 to 8 bays. If you’re shooting in RAW or filming 4k Footage, 2 bay devices are almost out of the question, a 4 bay NAS device would be a nice starting choice.
- RAID: I strongly recommend a RAID setup on your NAS, the redundant one. That’s when the data is being replicated on multiple drives allowing for at least one drive to fail without any loss of data. This is another reason why you wouldn’t want to have a 2 bay NAS box. There are different types of RAID setups. To break it down in simple terms, you can either have a mirror setups where the data is broken in half (ex. 2x3tb drives with identical data on each) or 1-2 swappable drive RAID (ex. 4x3tb units where 1 drive can fail without loss of data). The downside of mirror setup is that you only have half of your storage capacity to use. Some manufacturers offer their own RAID configurations that have hybrid data splits.
- CPU: A CPU with multiple cores and higher clock speeds are preferred, especially if you’re going to have multiple users accessing files at the same time.
- RAM: Random-access memory is very important for large file transfers. For photographers/videographers, this feature is very important since our files are typically large. If you are planning to work on files directly on the NAS – the more RAM the better. 2GB is minimum, some brands let you manually expand RAM up to 8GB.
- Ethernet: NAS devices are primarily connected to a network via Ethernet cables. Different NAS boxes will have from 1 to several Ethernet ports. A single 1Gb port in theory can have up to 100Mbs of data transfer, but it practice it never reaches max and gets about 95Mbs. Many NAS units allow link aggregation if you have more than 1 Ethernet port, where you can use an additional switch to split the bandwidth and get up to theoretical 200MBs (2 ports), 400Mbs (4 ports). If your NAS operates as a server and it need 100% uptime you can put each Ethernet port on a different ISP (internet service provider), so if one line goes down it would send/receive data from the other one.
- USB: These are usually used to connect additional external hard drives or a wireless internet dongle. USB3 is faster than USB2 so it’s obviously
- HDMI: You can connect NAS directly you a TV and have it serve as a PLEX media center via HDMI. If that’s a feature you are looking for, then look for this port (few manufacturers include HDMI in NAS).
- eSATA: This port is used to copy files to/from external devices. Its transfer speeds are faster than USB (SATA Rev3: 6 Gbit/s vs. USB 3.0: 5 Gbit/s) so it’s sometimes preferred.
- SSD Cache: Solid state drive cache stores most frequently accessed files and since SSD has very fast transfer speeds it will speed up your workflow. Some NAS manufacturers offer separate compartment for SSDs while others allow SSD placement in one of the drive bays.
- UPS: Uninterruptable power supply works on batteries and makes sure that all the data transfer is complete before safely shutting down the unit in case of power loss. This is an important feature especially if you live in an area with frequent power surges. Some NAS units have built in UPS that makes sure you don’t have any data loss or corruption during power failure. If your unit does have this feature you can always purchase a separate UPS unit.
- Info Screen: Most NAS units just have LED lights showing the status of each drive. While this is useful when a drive fails it doesn’t represent the scope of potential failure. Some manufacturers offer info screen showing full status of the unit, so if a major failure happens you can quickly diagnose it.
- OS: Last but definitely not least is the Operating Software of the NAS unit. There is a tremendous difference in ease of use and functionality of the operating software between manufacturers. Some offer very robust operations, some offer super simple plug and play solutions, while others offer versatile and user friendly software.
There are numerous Server NAS manufacturers and each one offers slightly different components and functions. Seagate and Western Digital are one of the players, but while I would use their hard drives in my NAS I wouldn’t recommend their NAS units. It may work for home setups, but not for working photographers.
Then there are NAS devices by Netgear and Buffalo. They mostly specialize in large corporate NAS setups and are not a very good fit for a small photography business. The three brands that I would focus your attention on are Drobo, Synology, and Qnap.
Qnap is one of the best options out there and my personal favorite. They don’t skimp on features and really know what they are doing. Previously their QTS software was clumsy, but with the most recent updates it has become much better and at this point is probably on par with Synology DSM software. Qnap is usually on the edge of progress and they try to include as many new features in their boxes as possible, like their recent addition of Thunderbolt 2 connection. So it’s definitely one of the leading contenders.
Drobo is very popular among the photo community. They provide very well designed and constructed units with super simple operations. You don’t need to know anything about networking or even IT. It’s a full-on plug and plays solution. You can just insert bare drives without any trays, and they include small SSD Cache and UPS batteries inside their units. However, the OS might be a bit too simple for some. It doesn’t offer any advanced features.
Synology. Their OS is the best on the market, it’s browser based and looks like a real OS that’s fully compatible with Mac, PC, and Linux. While it offers tons of advanced features, you don’t have to use them if you don’t want to. It’s fairly simple to operate if you just want to have a backup. The downside is they don’t usually include additional features such as HDMI port, UPS, or Info screens.
