Will wait till end of this yrs see Amazon sale got cheaper iromwolf or not. Would like to get 4pcs 12TB or higher.

Local damn expensive for NAS HDD.

It might be due to the shrinking of the HDD market, the price can't be cheaper anymore? SSD is getting cheaper.

But I read all said the same. Better to be have a same brand and type of HDD for NAS. If mix, will effect the speed. Not sure what else.

sigh.. my wd red 6tb is failing too
and out of warranty

Synology DS418j or DIY with FreeNas/ Open MediaVault is recommended if I want to have at least 4 x 2TB storage ? Total Newb here. would like some inputs. Thank you

1600 unfortunately i installed a nvidia 1050 gtx in it. i'm using it for plex transcoding, and win10 vm (and storage obviously). just upgraded to 16gb dd4 crucial ram. 4x4tb raid5 + 2x 250gb samsung 850 m.2 sata ssd raid1. also have a wireles QWA-AC2600 addon installed.

yes i too am concerned about bit rot and silent corruption also. for now i got raid scrub for ext4.....

i'm waiting for the zfs to come out for qts.... nothing beats end to end checksum. zfs is superior than btrfs in that sense.


https://linuxhint.com/btrfs_vs_openzfs/



but does zfs require ecc ram to be viable?

i know zfs is not perfect
https://louwrentius.com/the-hidden-cost-of-...r-home-nas.html

but it's got a lot going for it, especially keeping data integrity (end to end checksum) and also alerting the user for files that become corrupted. i'm uncertain that ext4 is up to the task for that

i also got other models over the years


ts-509 pro (i started out with this, a 5bay. which is good because i needed 5 bays ish)

ts-659 pro II

ts-653a

ts-877

ts-128/ts-228


my latest is a tbs-453dx (i use this for portable )


the N300 price at first look, may seem attractive, but it's hot and also compared to seagate and wd, it uses more power which means a bigger electricity bill yearly operating cost. in long run that adds to the total cost....

seagate has supposedly better smart test with the ironwolf health management they made. but i heard the hdd is louder than the wd red for noise.

i opted for wd reds, although i started out with hgst deskstar nas 4tbs (hgst got bought out by wd)


for the syn vs qnap native apps, there are pros and cons for each. but regardless which, i don't trust simply port forwarding the services for remote access. i would only consider using VPN (ideally on router) to safely access the NAS.

i'm not too familiar with syn, but with the qnap they added their own vpn integration so that you can connect a windows/mac pc to your QNAP through VPN client and vpn server (they made Qbelt for their native vpn client, although they do support openvpn for vpn server). so at least they did that.

neither of these brands bothered with the codec licensing, so i don't take their video native apps seriously. instead i recommend plex and kodi. Or you can use smb to your pc and use mpc-hc for your video playback.

Even with my mixed brands the speed still can max out my LAN gigabit bandwidth.


You treating your NAS more like a PC

No matter which is superior, as long as have protection against bit-rot and more importantly data degradation, is very much good already. BTRFS and ZFS provide this as well as self healing.

https://blogs.oracle.com/timc/demonstrating-zfs-self-healing

Recently plenty case of NAS being bruteforce and ransonware also give good reason to block your NAS from being accessible to the internet.

yeah i don't know why people think port forwarding nas is a good idea.

if they really MUST have remote access, then a properly configured vpn is the way to go.

myqnapcloud i disable.

kena before my NAS bruteforce. Slow down the network like crazy.

Last last check, hack from China from the log list.

This is a good article about bitrot, self healing, Copy On Write snapshots, and many more
https://arstechnica.com/information-technol...-filesystems/2/

You should enable setting to auto black list IP once it detect X number of unsuccessful login attempts at a X period.
I even put black list on IP from countries that is known to have plenty of active hackers.

Since the recent ransomware case on NAS I even have created another admin account and disable the default admin account.

i read before. yes it's the best article i've seen on this topic

that said i thought i read somewhere that in regards to end to end checksum for data integrity, zfs is better than btrfs in that aspect. btrfs does add some cool features though.

Guys, what's the best price per GB NAS drive currently?

need to replace 1x3TB WD RED and 1x6TB WD RED

*pokkai*

The cheapest now should be Toshiba.
But it run much hotter, more 5c that WD and more 10c than Seagate.

As per WD website on IronWolf Pro specs:

https://www.seagate.com/as/en/internal-hard...wolf/#pro-specs

EG for 4TB drive, what differentiate:

Ironwolf Pro 4 TB (ST4000NE0025)

VS

Ironwolf Pro 4 TB (ST4000NE001)


Thank you

See the spec sheet
https://www.seagate.com/www-content/product.../100803998g.pdf

vs

https://www.seagate.com/www-content/product.../100844774c.pdf

At a glance I saw different number of head and disc for same capacity.

I see .. just different revision and another one is phasing out since 2018

Thank you

cheaper yes but doesn't always mean better.

it runs noisier, hotter and uses more electricity annual operating cost. and ontop of that is ? how reliable are toshiba hdds? i don't know.

these days i get wd red 4tbs. seagate ironwolf has their IHM supposedly a more reliable smart test mechanism to identify when a hdd is going to die.

wd bought out hgst so perhaps there is some technology transfer there. but with seagate? maybe they have improved since last time, shouldn't be an issue. but i think the wd reds came out cheaper?

also technically i heard people say the seagate is noisier than the wd red? supposedly.

Interestingly Backblaze is full of praise when talking about Toshiba reliability. You can read their test result at this link
Seagate still the highest for failure rate, but it also maybe because they have the most drive. Still I feel it's not much difference between all brands.

The hotter issue, I feel all about the same psychically. Maybe it's how and where the sensor is being located.

Noise too I didn't notice any difference, maybe cause my NAS about a meter away.

is it? i'll check that out.



yeah but what toshiba hdd specifically?

i look at the mentioned 4tb (MD04ABA400V which by the way is a SATA 2, not SATA 3 https://iprice.sg/compare/toshiba-md04aba400v/ ) and thats not the same as the mainstream N300 NAS hdd.

If the positive reviews were specifically for the N300 model hdds, then that would be impressive and relevant to most of us wanting to buy a new hdd for NAS. but i did not see this model mentioned in back blaze


are any of the data pertaining to the Seagate Ironwolf NAS hdd series?


The cheapest and most relevant hdds to know about AFR is the

- Toshiba N300
- Western Digital Red
- Seagate Ironwolf

we need the AFR (annual failure rate) info for these hdds specifically.

Only options outside the drives are the much much more expensive, wd red PRO, and etc. Sure if you want highest available capacities and top grade enterprise level specs, then there is a big premium for that.


This year i bought at least 2 x wd red (non pro) 4tbs. I saw that the toshiba N300 was cheaper but i opted not to get it due to the reasons i mentioned earlier.

It's sata 3
https://www.cnet.com/products/toshiba-md04a...-tb-sata-6gb-s/

They use more of desktop and enterprise HDD, but it's a good indication of a manufacturer HDD reliability. With their huge data farm, this usage is as extensive as it can get.

Most manufacturer also always release revision after few years so it's hard to have long term test

any sifu can teach me strategy of using Nas to cover a shop of 27 staffs for regular file sharing & backup copy.

they bought a synology 4 bay but messed up config. i plan to copy out full data then setup everything as new

Since so many people accessing the data, you will want to have frequent backup of the data before being edited. Use Snapshot with Copy On Write, it will only make copies of the data that will be edited so the backup size will not be big. You can set it to schedule backup every tens of minutes or hour, depending how often you need it.

Use BTRFS or ZFS file system as it have Checksums, basically it is to avoid data corruption.

Use RAID 1/5/6/10 to have redundancy so that if one of the HDD/SSD failure then you still copies of the data. If use BTRFS then don't use RAID 5/6 as it's not compatible.

Don't see Snapshot and RAID as your only backup, it is more of a backup for that current time. You should also have external backup of your data, preferably 2 external backup at different place.

If it involve very frequent of a lot reading and writing of small file then you might want to consider using SSD to minimised the seek time. If frequent transfer gigabytes of files then consider using faster than 1GB wired connection.

You can also make volumes that's only accessible for certain user group. Also can set the maximum allocated volume size for each user or group.
