2 x Audi's
1 being a police car loaded to the hilt with all the Police Gear in the trunk... passenger cage, 2 x police, radios etc etc.
1 being the standard car of identical model
Program them both the same and lets watch what happens
Hmmm, Guess I am really unlucky
47C Here in my garage last year..... only get like 10mins to play before things start shutting down.
BTW 15000 RPM HDD's burn the fingers when you run them in those temps ;)
How far apart is the G7 and the MSA70?
All you need is to hook the onboard P410i to the MSA70 and use the onboard P410i to raid up the drives in the MSA70
Search ebay for either a SFF-8087 to SFF-8088 cable and poke it straight out the back of the G7 into the MSA70
or buy a more neater setup...
At 25 second mark, it show what to me looks like a BMW R1200 Flat Twin Motor and a fuel tank (unknown capacity).
So I am guessing maybe more like 1-2hrs flight time might be more the fully loaded adult model times.
No Raid 1 supports as many HDD's as you like
Raid 1 is a Mirror ---- eg 2nd drive is a mirror copy of the 1st drive
no reason why you cant have a 10 way or more mirror set if you like.
for shits and giggles for example lets make a 3 way mirror....
then once all drives are synced...
Well I just cranked up an IBM server ( X3400 M3) after 2 months of being turned off
one of the 1TB SAS drives is dead (tick tick tick) cant spin up.
It happens yes when they just sit there.....also happens when they are being used.
HDDs fail....hence why backups etc are important.;)
I beg to differ
A good reason to partition the disk is this
You create a raid array of say 4 x 2tb seagate drives.
Later down the track you have a drive fail.... So you pull out the dead seagate drive and replace it with say a WD 2tb drive..... But the WD is slightly smaller.
So your using the full disk and not partition for MD Raid?
I would rebuild it again, this time making an aligned partition 1st, Then Create the array from the partitions.
eg partition disks with 4k sectors
sudo parted /dev/sdc

was the drive actually bad....
or was it crippled on NCQ ?
Os thinks the drive has an NCQ value of 32 (most drives these days).... but drive actually has an NCQ of 1.
as I have found out with a bunch of similar drives (seagate STblahblahM001)
2 out of the 12 that I have are...
M1015 can't see whole backplane.... Or can't recognised some drives ?
I have had it where it can't recognize some drive in the bays once pulled...
Grabbed a torch and had a look at the sas connections, and there were dust bunnies in them.
Paintbrush and some air to blow them out and all...
Synologies are / should already be setup to handle WD green drives
On one of my systems I have 4 old 2TB Greens 2 x EARS and 2 x EADS
have a look in the folder

if your going to use tape for archiving......
DO NOT use compression, and or do not backup compressed files to tape.
Just plain stream the files to tape using (amy unix variant) TAR
Even if a tape breaks......you will be able to stream the data off of the tape.... up until the...
As a caveat for using ext4 with volumes > 16TB, you'll need to use a newer version of e2fsprogs if you want to create a filesystem that will support 16TB+. Ubuntu 12.04 comes with e2fsprogs version 1.42, and this version supports creating a 64bit filesystem (will support > 16TB) like this...
