I think ideally we would like to spend less than $400 but can be flexible to get something up and running to her needs. We had talked initially about 10-14TB of storage. Does putting x2 8TB HDD inside a two bay NAS setup give you 16TB of storage or does it give you double backup of 8TB of storage?
RAID is not a backup. The point of these NAS devices with multiple drives for redundancy is that if a drive dies, the NAS still works and your data is still accessible. Instead of you being stuck until you can replace the dead drive and restore from a backup, you can continue working. Order a new drive, and when it arrives you swap it in for the dead one and rebuild the NAS array.

RAID on a NAS does not constitute a backup because if you accidentally erase or overwrite a file on it, or ransomware encrypts it, it's gone. So even if you have a NAS, you still need to make backups of it.

So if your GF needs 100% uptime for this data, then a NAS is what you want. If her data storage needs exceed what's commonly available from a single external drive, then a NAS is what you want. If she needs to access the same data/files from multiple computers/devices in the house, then a NAS is probably a good choice.

But if she just needs a big drive on which to dump her data, which is already being backed up elsewhere, it's not time-critical if the drive dies (e.g. she can get another copy of the data from the school), and she only needs to access it from a single computer, then a big external hard drive will be cheaper, faster, smaller, and simpler.

Most people use a NAS in redundancy mode (RAID), so that it'll keep working if a single drive dies. In that case 2x8TB drives = 8 TB of storage. (The storage is the number of drives minus 1, so 4 drives = 3 drives worth of storage.) But as I mentioned, don't think of it as a backup. Think of it as insurance against single drive failure.

It is also possible to use a NAS to glom a bunch of drives together into one virtual drive. So 2x8TB = 16 TB. Just be aware that if you do that and one of the drives dies, in most cases all your data is gone. And if she needs to do this but she's the only one who's going to use the storage, then a RAID enclosure will probably be cheaper than a NAS. With a NAS you're paying extra for a small computer inside to present the HDDs over the network. A RAID enclosure typically just has cheaper RAID hardware to combine the drives into a virtual drive in a variety of ways, and usually attaches via USB like a single external drive.

You can do either one:
RAID-1 gives you 8TB w/redundancy
JBOD/RAID-0 (striping) gives you total capacity

Can someone help me out?

I'm trying to come up with solutions for my girlfriend who is in grad school and deals with large and frequent file transfers while working with GIS mapping for her research. She has an office setup at both home and the university and we have discussed NAS options to help with data backup and access but I'm not really familiar with the products, setup process or generally where to start when doing a build.

Do I need to start by finding NAS rated HDDs?

Is it as simple as selecting a drive or two and putting them in a NAS station like below:

WD - My Cloud EX2 Ultra 0TB 2-Bay External Network Storage (NAS) - Charcoa [bestbuy.com]l


Would you recommend buying a "station" like above and adding our own compatible HDD drives to the available bays? Or buying something that already includes the drives?


And to get up and running do you just buy a setup and plug it into an available ethernet port in your modem/router/access point and follow included setup instructions to save data from a device to the NAS? And can data be saved to / accessed from the NAS both while on network and off-network (remotely)?

I'm not very tech savvy and the only experience I really have with HDD is "shucking" externals to put into things like security camera NVRs or upgrading storage inside things like gaming consoles.

I think ideally we would like to spend less than $400 but can be flexible to get something up and running to her needs. We had talked initially about 10-14TB of storage. Does putting x2 8TB HDD inside a two bay NAS setup give you 16TB of storage or does it give you double backup of 8TB of storage?

Thanks in advance for any help and/or steering me in the right direction!

Just placed an order for three but questioning the wisdom of purchasing 4TB drives any longer. Yes, these drives are a bargain @$78 but considering the "price of real estate", i.e., the cost of a slot in your NAS/RAID, then 4TB is no longer a cost effective use of resources unless you repairing an existing array. I'm thinking that 8TB drive should be the minimum capacity for RAID5 configuration except the 8TB bare drives are currently inflated at $200+.

You could go the route I did with my little Plex/everything else server: USB docks and Windows Storage Spaces. I currently have 4x2TB drives in a parity (think RAID-5-ish) array and 2x1TB in a striped array. Performance is what I would call acceptable and will not be constricted by network speeds.

Things I like about it: Direct connection to computer via USB. I have this in a storage room with the drives in open-air docks with a fan blowing over them, keeps them cool (as opposed to a tight enclosure). I can continue to expand the storage space by adding new drives as I need them. Not much risk aside from the drives themselves, docks are cheap and easy to replace and recover from failure.

Things I don't like: I am using dual-drive docks and they take up a lot of space and need lots of outlets. I know there are quad-drive docks available.

One thing, as someone else mention, RAID is not a backup system. If this is critical data needing backing up, I highly recommend BackBlaze for backups. Its like 60-65 a year for unlimited backups from a single machine.

Good timing. One of the synology raid WD black drives finally blew out after 10+ Years service. Purchased 2x of the 4TB red plus 256gb cache from Newegg. Coupon code didn't work since not shipping to Cali, but it was worth a try. Still a decent deal for around $150 2x red plus.

As the other person noted, the Amazon and BB are only 64MB cache, so get these from newegg for marginally better performance at the same price.

Thanks OP!

You have a few options. You can go the Synology route for easy dummy proof setup. Another easy option is to buy your own server like the Dell T40 that often goes on sale. I personally use a Dell T40 with Windows 10 and StableBit DrivePool installed ($29.99). In either case, you will need to purchase hard drives. If you want to take it a step further, you can setup your own cloud with NextCloud. This is a little more complex, but there are a million videos on YouTube that hand hold you through the process of setting up Nextcloud. These two options are an alternative to setting up a more traditional Linux based or windows server based server with RAID. Here is my setup:

-Dell T40 Server
-4 WD Red 3TB hard drives
-Windows 10 Pro
-StableBit Drive Pool (this is the software that pools your drives and is an alternative to RAID)
-Optional Cloud setup with Nextcloud (follow you tube instructions)

This setup has been solid. More solid than my old Synology. The only time I have had to reboot the system is if there is some sort of power outage.

Get a NAS with 4 or 5 bays. Like Synology DS920+. Fill it up with NAS grade HDs like WD Red Plus in any size you think you need based on a RAID 100 or 6 configuration. Use Synology Desktop client to sync files Dropbox style.

Is this good? Would waiting for a 7200rpm drive be better?
Depends i got 4TB Blue from 2017 writes and reads 150MB/s which is on par with most 7200RPM drives.
