Dr_Frankenstein got a reaction from Mattias Edeslatt in LTT Storage Rankings
This is an update on my previous two posts
412+
1815+
Hardware
Synology 1815+ and Synology DX413 Expansion Unit
HDD 1: 4TB Seagate ST4000DM000
HDD 2: 4TB Seagate ST4000DX000
HDD 3: 4TB Western Digital WD40EZRZ
HDD 4: 4TB Seagate ST4000DX000
HDD 5: 4TB Seagate ST4000DM000
HDD 6: 4TB Seagate ST4000DM000
HDD 7: 4TB Western Digital WD40EZRX
HDD 8: 4TB Seagate ST4000DM000
HDD 9: 256GB Drevo X1 Pro
HDD 10: 3TB Western Digital WD30PURX
HDD 11: 3TB Western Digital WD30PURX
HDD 12: 3TB Toshiba DT01ABA300
HDD 13: 2TB Seagate ST2000VX000
Software and Configuration:
Running Synology DSM front end GUI, the 8 x 4TB drives in the main unit are running SHR2 (equivalent to RAID6 so that's 32TB (29.12TB RAW/21.81TB after redundancy) the other 4 drives are running SHR (RAID5) 11TB (10.01TB RAW/7.26TB after redundancy) finally the SSD contains all my Docker containers and any native Synology apps the SSD works really well for this usage and is much quicker than using it as an SSD read cache which I found had a negative performance impact on the unit.
Usage:
I upgraded from my 412+ around a year ago picking up an 1815+ for around £600 on eBay, about 6 months ago it was warranty replaced due to suffering from the Intel C2000 bug. It runs 24/7 and has been upgraded with 16GB of Crucial RAM, I use it as my main storage server, I make very good use of Docker as all my most useful applications for obtaining Linux ISO's are Dockerised (see my website for guides) It also runs a Minecraft server which is open for anyone to use.
I rarely pick up brand new retail drives (as I am cheap) all the drives currently in use have been either shucked from second hand external drives picked up from eBay or other sites. If you bargain hunt this keeps costs much lower but obviously has inherent risks with not knowing the drives history.
Backup:
My 412+ is has been effectively retired and now is used for backing up important data, I also keep archives of my photos offsite at work. The 412+ has 6TB of space as I tend to use smaller retired drives in it. I also have a HP Microserver which I just have to play around with, that has a real mish mash of ancient drives from 250GB to 320GB.

We survived! I now have 3 HGST drives, 21 Seagates, with 1 HGST spare on my desk. 4 more Seagates are still working through RMA. I'm eyeballing adding all 4 of them as hot spares via the SFF-8088 connector, but need to consider if it's really worth the effort to do that.

Got an update coming within the next couple of weeks. Complete rebuild and another 12 TB added.

Even if you are backing up to a decent medium if this is long term storage I would also use Multipar to create Parity files for the backups, this means even if you had a small amount of degradation due to Bitrot, you would still be able to restore the files in their original form.

I have updated my post as I have just installed the 4TB Seagate which is replacing the 3TB which started throwing up tons of damaged blocks.
I will update the screenshots once the drive has finished being added to the volume in a few hours.....

Hardware
CASE: Bitfenix Prodigy (white + window side panel)
PSU: BeQuiet Straight Power 400W
MB: ASRock FM2A85X-ITX
CPU: AMD A6 5400K
HS: Alpenföhn Brocken + BeQuiet Shadow Wings PWM 120mm
RAM: 4GB(2x2) DDR3 1333MHz @ 1600MHz
SSD: PNY XLR8 120GB
HDD: 5x 2TB Seagete ST2000DM001
---[extras]---
Rear-FAN: BeQuiet Shadow Wings PWM 140mm
Front-FAN: Bitfenix Spectre Pro 230mm
Noise-insulation mats from Caseking
~ 1 Meter of RGB-LED strips inside the case
6x Nanoxia black sleeved sata cable
1x Nanoxia white sleeved sata cable (SSD)
Software and Configuration:
The Server was planed to be plugged in directly to my TV so that I would have been able to watch movies and such via XBMC and also Game on it...Therefore I had a dualboot with win7 (for gaming) and Ubuntu for server purposes, XMBC and what not. As this didn't work out that well I endet up with Arch on the SSD (no GUI) running a software RAID5 via mdadm with the 5 HHDs, so that I have 10TB total/8TB useable space accessable via Samba.
Usage:
I have some movies and series on it which I enjoy mostly on my TV via Plex and a Chromecast or on my Tablet in Bed. Another (if not the biggest) usecase is temporary storing stuff. I do some pc repair for friends and family as a hobby and got used to diskdump their whole storage (mostly 120-500GB) on my NAS before doing anything bigger on their pc's (and yes I ask them before doing so). I normally keep these backups for about 2-3 Months just in case they miss something/need to access their "old" data. I also carry it with me to some LAN parties with friends where it is used to exchange data.
Backup:
The server itself has no complete backups. I think the RAID5 prevents the biggest issues and for the rest I have seperate backups on external drives of really important stuff like pictures.
Additional info:
As you might have noticed the server is currently pretty full. I'm planing on replacing all HDDs with 4/5 TB ones (maybe WD Green's) sometime arround the end of this year.
For those who wonder why there are sleeved sata cables, LED's and what not - This build was planed as an eye-catcher. It currently sits 1,5 Meters high on a IKEA-Kallax (2x4) shelf and looks down on my room...what in my oppinion looks pretty awesome

Well it looks like I timed my purchase of the WD Purple drives just right, my second 3TB Seagate started failing yesterday initially I got an email from my Synology that 1120 bad sectors were found, overnight this has gone up to 25272!, most of these have been remapped and 488 are awaiting allocation meaning there is nothing left to re-assign.
I have just got a decent deal on a USB 4TB Seagate from Amazon for £89.99 so it will be replacing the failing drive after breaking it out of the USB enclosure.

Dr_Frankenstein reacted to 91Chris in Choosing disk for a NAS?
I run 8 Greens in RAID Z (I know it's not the most efficient number of drives for Z)
You can enable TLER on greens
You can have them not spin down/park at all
Speed is more than good enough for media storage and backups
Red's are the "NAS drive" but not everyone needs them.

Okidoki, I was curious about HDD statistics, and TADA!
Since almost everybody has indicated at least the vendor and specific size of their
drives, I was able to put this together (yes, I had some free time...).
@looney, @Whaler_99, @MG2R: FYI.
Of course, it can also be found in the actual rankings post, but I thought I'd put
it here as well for those too lazy to click that button.
EDIT 2: OK, should be fixed now.
EDIT 3: Added average drives per system.

Dr_Frankenstein reacted to LinusTech in SSD's are so overrated.
SSD performance has nothing to do with boot time. Who shuts down their computers these days anyway? Modern machines sleep and wake so fast and use maybe a couple of watts when sleeping.

Updated 11/09/2014 - Replaced a 3TB Seagate with a 4TB due to bad sectors
Updated 13/02/2015 - Replace another 3TB Seagate with a 4TB due to bad sectors
Hardware
Synology DS412+
PSU: 100W Power Brick
MOBO: Custom Synology Board
CPU: Intel Atom D2700 2.13Ghz Dual Core
RAM: 2GB Kingston DDR3
HDD 1: Seagate Barracuda 4TB (ST4000DM000)
HDD 2: Seagate Barracuda 4TB (ST4000DM000)
HDD 3: WD Purple 3TB (WD30PURX)
HDD 4: WD Purple 3TB (WD30PURX)
Software, Configuration & Usage
I have been using Synology Products since 2009, starting with a very slow 209j then a 211j, a 212+, and finally picking up this 412+ for about £300 on eBay.
I am now using Synology Hybrid RAID (RAID5) so out of the 14TB of drives I get around 10TB actual usable space, The majority of the time the NAS is used to stream media to my Intel Celeron NUC or to my OnePlus One using the DS Audio app when on my way to work during the week.
I have a 3 way backup scheme.
3TB USB Drive for onsite weekly backups of everything but TV+Movies 2TB of Baidu Cloudstorage where I keep monthly encrypted backups of photos and unencrypted music 500GB USB Offsite Backup where I do monthly backups of the most important files this is kept in a locked draw in a secure building with 24/7 security The 412+ is a great device and the ATOM gives it the grunt to happily saturate my Gigabit network, it has had two hardware modifications, the first was the additional 1GB of RAM which is not officially supported, and I recently turned the two 90mm fans around meaning they suck air in from the rear of the chassis, this has meant less dust is getting into the NAS as before it was a dust magnet.
