BUILD Sanity check for a X10SRL-F based build

[F00D]

I'm looking to build the following in the next 1-2 months.

supermicro MBD-X10SL7-F-O Micro ATX Server Motherboard LGA 1150 Intel C222 ($225)

Intel Pentium G3470 ($50)

Crucial 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC ($115)

SeaSonic G Series SSR-550RM 550W ($79)

2x SanDisk Cruzer Fit 16 GB USB 2.0 Flash Drive (2x $8) as mirrored boot drives

Fractal Design Node 804 MicroATX ($79)

Chelsio S310E-CR 10Gbps SFP+ ($40)

8 x Toshiba X300 5TB for Raidz2 ($150)

This box is intended as a directly attached storage box for my windows machine for the foreseeable future. Due to factors out of my control linking them up via the LAN is impossible. Most intensive thing this box would ever do is run samba and maybe (if I can pass a network connection to it) rtorrent/rutorrent.

Performance isn't the end all be all of this machine, I'm aware samba will cap the connection speed between the PC and the FreeNAS to maybe 200MB/s if I'm lucky.

The drives are ... untested to say the least however considering the way the Hitachi sell off went down I'm willing to take a gamble on these drives under the assumption they're still manufactured at the same factories that produced the Hitachi drives of old.

Is there anything I'm missing about this build that I've forgotten about? Are you going to try to convince me to get 4TB WD reds at the same price because they have a better warranty and are known to work better?

The 5TB Toshiba's are certainly at an amazing price point. I've been watching those for awhile. The reviews I see on those is that they are generally reliable, but there are two complaints I hear voiced constantly:

1. Apparently, even under normal usage conditions, they make a hell of a racket. Apparently there is a tremendous amount of ambient seeking noise, that reminds people of the old Seagate ST238-R's from the 80's.
2. I hear a lot of people that sound like they know what they are doing saying the temperatures of the drive are very hot, and hard to control. I guess this isn't a surprise since they are higher speed (7200 RPM) platters.

Not too many of us use those drives. However, I seem to remember Allan Jude (who is definitely not a moron), tell me he has bought a zillion of these for his NASes and they are perfectly satisfactor. @Allan Jude I hope I am not putting words in your mouth?

I indeed have 48 of these 5TB drives installed as 2 machines with 2x12 disk RAID-Z2s. that backup my monster storage machine (3x12 disk 6TB He6 SAS drives).

I have never noticed a noise level, but these drives live in my server room, with loud servers.

Comparing them to another machine in the same rack, room Air Conditioned to 22C:

12x 3TB Seagate ST3000DM001:
190 Airflow_Temperature_Cel 0x0022 070 066 045 Old_age Always - 30 (Min/Max 24/34)
190 Airflow_Temperature_Cel 0x0022 070 065 045 Old_age Always - 30 (Min/Max 24/35)
190 Airflow_Temperature_Cel 0x0022 069 050 045 Old_age Always - 31 (Min/Max 25/35)
190 Airflow_Temperature_Cel 0x0022 068 048 045 Old_age Always - 32 (Min/Max 26/36)

24x 5TB Toshiba MD04ACA500:
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 36 (Min/Max 26/42)
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 37 (Min/Max 25/43)
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 37 (Min/Max 26/43)
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 35 (Min/Max 27/41)

So, while they don't seem to be problematically hot, they do seem to run 5-7 degrees C hotter than my Seagate drives (of which I have over 100)

For comparison, the monster storage server is in a data center, I am not sure the room temperature, but it should be around 20C:
36x 6TB HGST He6 (HUS726060ALS640):
Current Drive Temperature: 32 C
Current Drive Temperature: 35 C
Current Drive Temperature: 34 C
Current Drive Temperature: 35 C


Anyway, so far I have not had any problems with the Toshiba drives.
#dd if=/dev/da20 of=/dev/null bs=1m count=20k
20480+0 records in
20480+0 records out
21474836480 bytes transferred in 108.944135 secs (197117876 bytes/sec)

So a 20GB linear read did pretty close to 200mb/s, so they are pretty good drives overall.
