any concerns with this drive to work in unraid?

None.

 

The only concerns I've ever had with Samsung was their RMA process. While I prefer Western Digital and Seagate, Samsung has been making drives for as long as they have been. My concern about RMA process is mainly due to the fact that when I worked at a local shop years ago, they used Sammys in all of their cheap builds and I can't tell you how many systems came back dead for warranty service.

I was mainly concerned that if its an advanced drive and knowing some need jumpers and some need firmware updates......this isn't the ideal size I wanted to start with but I just come across alot of new things I now want to do including unraid....lol

 

so right now I'm in the middle of truing to build an unraid server......build a XBMC box.....and decide on a new TV.....lol

 

so at this price I can't pass this up unless there are issues that could sway me

 

trying to do all of this and not piss off the boss is a tough road to go down....lol

 

Thanks!....and hopefully this helps some others too!!!!

There is possibly a concern with Samsung drives, they report wrong (too low) temps in unRAID. There have been multiple reports of this occurring. Here's the most recent report of this issue http://lime-technology.com/forum/index.php?topic=8345.msg80708#msg80708

 

What this means is you can't trust the temps they report, but you could be alright as long as the temp they report +5 to +10 C (the amount they're typically off by) is within the drive safe zone.

 

Disk 3 [sdg]: 16?C (DiskId: SAMSUNG_HD154UI)

Disk 4 [sdh]: 16?C (DiskId: SAMSUNG_HD154UI)

 

Well the room temperature this morning was 63F. So 63F is 17.22C.  I see that the Samsung drives aren't reporting the correct temperature.

Just an FYI - the myMain plugin has a setting that lets you adjust for a drive that is under of overreporting drive temperature.

 

e.g., add this to the mymain_local.conf (first parameter is the disk serial number, last is the number to add to the report drive temperature.  (In this example the sensor is reporting a value that is 10 degrees to high, so you need to subtract 10 from the reported value).

 

SetDriveValue(5QG0L000, temperature_celsius_delta, "-10")

 

Note this is only applicable to thy myMain plugin (of which an update is in the works!)

Good to know, bjp999, thanks!  However, how would one accurately determine the offset value? 

Good to know, bjp999, thanks!  However, how would one accurately determine the offset value? 

let all the drives spin down, wait a number of hours to let the temperature stabilize, then take the temperature (or assume the adjacent drive should be the same if it has the same cooling.)

 

Personally, I use one of the inexpensive infra-red thermometers.  Cost me about $20 and I can get temp readings easily.

Are the temps on the exterior hull of the drive really indicative of the drive's internal temperatures?  I figured the hull would be significantly cooler.

 

Also, don't some drives just run hotter than others?  I know that my older 7200 rpm drives are at least 3-5C hotter than any of my green drives during any conditions.  So would you only compare 5400 rpm drives with other 5400 rpm drives, and 7200 rpm drives with other 7200 rpm drives?  Does age matter?

sounds like an issue a noob like myself can handle....lol

 

plus my current storage is busting at the seams so i really need to get my first unraid server up and running and the price on these will help a lot

Good to know, bjp999, thanks!  However, how would one accurately determine the offset value?  

 

Take it and another similar disk (same capacity/RPM) and put on a bench and connect (temporarily) to a test unRAID server.  When they are cooled to ambient, blow a house fan on the drives and boot the machine.  Bring up the Web GUI as soon as possible after the boot.  That should give you as close to apples-to-apples as possible to compute the offset.  ** BE CAREFUL IF YOU ATTEMPT THIS PROCEDURE.  HAVING BARE DRIVES SITTING OUTSIDE OF THE ARRAY IS NOT THE SMARTEST IDEA, AND YOU NEED TO BE VERY CAREFUL NOT TO DAMAGE THEM OR HURT YOURSELF IN THE PROCESS **

 

Alternatively, you could swag it based on temps of other drives in similar case locations.
