Looks like GIGABYTE kicked out some Xeon-D boards, but goddammit, still only one x16 slot  I want to replace my server chassis (it's been off for the past 10 months almost because of a few dead drives) since I have some time coming up, and I want to go full ESXi-based infrastructure with a Xeon-D based system. Should see some power savings over my current i7-920 + X58 based platform -- I idly wonder how much I could sell that used hardware for.

So I'm giving thought to programs like Cryptolocker and how to defend a NAS against it while still being convenient to use. The idea floating in my head is to make it possible to read and write files, but not to update or delete them. Is that reasonably possible with something like FreeNAS? Is there a better way to handle it?

Might go for the 1521 version to save some bucks. Where do you go for server type boards like this, usually ncix/newegg doesn't have much of a selection (although they do get some) Perhaps Lenovo will stick a Xeon-D in their next TS140.. That'd be pretty slick too.

To move files around, I remote into the server with a specific account just for that purpose that has no other access.

Is putting a NAS behind a wireless repeater or on a wireless USB dongle dumb? I have my XPEnology box on some devolo homeplugs, they're meant to be 1200mbos but I only get 300mbps (according to the devolo app) which is expected I suppose, but it frequently seems to drop out. The NAS is still running, doesn't reboot or anything and the light on the homeplug is on, but I can't ping it. Don't know if having it on wireless would be faster and more reliable - don't notice it dropping out on my phone at all and I have a 5ghz router

Yeah, short of a Cryptolocker variant that can actually infect FreeNAS and destroy your snapshots, they're going to be secure. They might even give you a warning if something else doesn't detect it first, when the footprint of your snapshots begins to balloon.

I created a thread for figuring out how to access my POS My Book World, if anyone can solve the mystery and restore my sanity. Considering how annoying a problem it's been, I thought it warranted its own thread. I placed it in the wrong forum, so it might be moved to House of Tech Support soon, fwiw.

Are there any cheap ways that I can use a USB external drive on the network. Or recommendations on a cheap single drive NAS? I'm looking for something to stuff into an attic to do backups of a surveillance system.

Check to see if your router supports USB hard drives. Some consumer-level ones do. Otherwise, yes single drive NASes exist. Like this - https://www.synology.com/en-global/products/DS115j

I've gotten a supermicro xeon-d server for work (5018D-FN4T) and it's a great little server. Just a little pricey, I think it was $1500 before RAM/Drive. If the gigabyte ones aren't much of a savings I'd definitely see about finding a supermicro. Dream setup would be a box like this and an HBA connected to jbod enclosure. Probably overkill for a family storage box but what the hell

I can't comprehend the taxonomy/nomenclature of Synology NASes, so what should I get if I want to get one with 2-4 bays? I mainly want to use it for backups (and remote backups like, idunno, CrashPlan) for use with bvckup and Time Machine.

Apologies if this has been covered, but it's a pretty long thread and the questions (like the one about a single drive NAS above me) are fairly specific. I'm looking for a price-conscious NAS setup in the 3-6TB range that will let me consolidate my music/pictures/videos and get to them from multiple computers, and potentially android devices (but that's a nice bonus, not a core feature I need). I don't really need to get to my stuff over the web, and frankly I think I'd rather only being able to get to it when I'm physically connected to my router. Am I dumb to just plug a cheap single drive NAS into my router and call it a day? I like the idea of a RAID setup, but not so much the price tag, especially since I can do periodic backups on one of the pile of external drives I have kicking around (none of which is big enough alone to put all my media in one place). I'm willing to spend more if $200 will buy me a flaming piece of crap that barely limps along and $400 will give me robust data storage with enterprise-quality drives that will last for the next 10 years, but my requirements are pretty simple. I really don't want to build my own because time is currently more valuable than money, but I'm OK shopping for a diskless shell and finding a drive(s) to put in it. I'm a former computer janitor, but haven't really done any networking since Server 2008, so I'm not really up on the latest and greatest tools to move data around. t have no issue setting up a device with a static IP and then mapping to it, though.

I think your ideas on price are way off. 2x4tb consumer NAS drives will probably cost at least 200-300, and that's without a shell. Enterprise drives will cost 50-100% more, but probably are not worth it. If, as you say, your time is valuable, you should consider how much time you would lose if your single drive dies and takes all the data with it (even it fully backed up, how much time & effort is it to restore and set up new device?).

How terrible an idea is single drive parity with 5TB drives? I've read the theory that unrecoverable read error rates are high enough that you'll get one while reading a 5TB drive, but isn't that just an argument that you can't use a single high capacity drive in general anywhere to keep data? I'm looking to scale up my home NAS from 2 mirrored 5TB drives to a 4 or 5 drive raid z1 array, and I'd really like to avoid losing 2 drives to parity or mirroring.

If you care about data loss, a single drive never has been a good idea at any scale. However, the real concern with unrecoverable read errors is during a RAID rebuild, since that's pretty much the only time you would ever read the whole drive start to finish. Three or four large drives combined are now large enough that when you do a full read of all of them to rebuild a failed drive, you're reading enough data to expect at least one URE during that process just based on the manufacturer-published URE rates. Here's the real answer on RAID parity: what is a bigger pain for you, restoring the whole array from backup, or the cost of one more drive? With that said, ZFS at least can save some of your data if, say, you run raidz and have a URE during a single-drive failure. Unlike most RAID solutions it doesn't just poo poo the bed and call the whole array garbage, it will tell you which files it can't recover so you can restore just that instead of the whole drat thing.

My thought was that backups are necessary anyway, and with how insanely fast home internet connections are getting restoring from backup wouldn't be as miserable as it used to be. Also, as you said, the checksumming filesystems should be able to recognize the corruption created by the URE and say "OK, that file is hosed, but everything else is fine".

URE typically kicks the disk that generated the URE out of the RAID, many different raid card manufacturers have a different way of handling this though.

It's something that has to be answered on a case by case backup. What does it cost to backup my data in full? How much does it hurt to lose any of it? How much downtime am I willing to endure to restore from my backup? How much is my time worth futzing around with this crap? These are somewhat hard to answer, but an extra hard drive is fairly cheap.

So I installed FreeNAS on my old Core 2 Duo machine, with 6gb RAM. my drives are plugged into SATA2 ports. The pool is configured in RAIDZ2. I'm getting 30MB/s transfer speeds, would that be pretty typical for this kind of setup?
