Is this Seagate Exos drive too good to be true? (lemmy.dbzer0.com)

I found this its the cheapest 10TB Exos drive on Newegg and looking to buy 4 of them. I will be putting them in my NAS that I use for my media library and pc backups. The price I’m posting this is $130, I’m also looking similar Exos drives that are $250 is there a difference? Should I shell up for the more expensive drives?

It depends. They're simply the most annoying drives out there because Seagate on their wisdom decided to remove half of the SMART data from reports and they won't let you change the power settings like other drives. Those drives will never spin down, they'll even report to the system they're spun down while in fact they'll be still running at a lower speed. They also make a LOT of noise.

Aren’t they meant to go in data centers? You wouldn’t want a drive in a data center to spin down. That introduces latency in getting the data off of them.

[-] TCB13@lemmy.world 13 points 9 months ago

That should be a choice of the OS / controller card not of the drive itself. Also what datacenter wants to run drives that don't report half of the SMART data just because they felt like it?

Data centers replace drives when they fail and that's about it. They don't care much about SMART data.

We used to use smart data to predict when to order new drives and on really bad looking days increase our redundancy. Nothing like getting a bad series of drives for PB of data to make you paranoid I guess.

[-] lemmyvore@feddit.nl 1 points 9 months ago

What kind of attributes did you find relevant? I imagine the 19x codes...

I've read the Blackblaze statistics and I'm using a tool (Scrutiny) that takes those stats into account for computing failure probability, but at the end of the day the most reliable tell is when a drive gets kicked out of an array (and/or can't pass the long smart test anymore).

Meanwhile, I have drives with "lesser" attributes sitting on warning values (like command timeout) and ofc I monitor them and have good drives on standby, but they still seem to chug along fine for now.

I got a set off ebay, Jesus christ they're loud. I ended up returning them cause I could hear the grinding through my whole house

I have 3 14tb exos drives. I have them in a Roswell 4u hotseap chassis. Running unraid.

It's nearly inaudible over the very reasonable case fans. No grinding noises. I can hear the heads moving a bit but it's quite subtle. Not sure why people have such different experiences with these

It's just the cheapest type of drive there is. The use case is in large scale RAIDs where one disk failing isn't a big issue. They tend to have decent warranty but under heavy load they're not expected to last multiple years. Personally I use drives like this but I make sure to have them in a RAID and with backup, anything else would be foolish. Do also note that expensive NAS drives aren't guaranteed to last either so a RAID is always recommended.

[-] rosa666parks@lemmy.dbzer0.com 4 points 9 months ago

Ok cool, I plan on using them in RAID Z1

[-] RunningInRVA@lemmy.world 11 points 9 months ago

Make that RAID Z2 my friend. One disk of redundancy is simply not enough. If a disk fails while resilvering, which can and does happen, then your entire array is lost.

[-] SexyVetra@lemmy.world 5 points 9 months ago

Hard agree. Regret only using Z1 for my own NAS. Nothings gone wrong yet 🤞but we've had to replace all the drives once so far which has led to some buttock clenching.

When I upgrade, I will not be making the same mistake. (Instead I'll find shiny new mistakes to make)

You must be running an icredible HA software stack for uptime increases so far behind the decimal to matter.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters	More Letters
HA	Home Assistant automation software
~	High Availability
NAS	Network-Attached Storage
RAID	Redundant Array of Independent Disks for mass storage

3 acronyms in this thread; the most compressed thread commented on today has 8 acronyms.
