    MicroServer N36L/N40L/N54L - 6 Drive Edition

    Yes, 2x3.5" drives in the optical bay is fine--my green drives sit in the low 30C range when spun up and never break 40C even during parity checks/sync.

     

    Very easy to slip a 2.5" drive under the optical bay, so I think 6x3tb (3.5") and a 2.5" for cache could be done easily. This is basically my setup except that I'm using 2TB drives because I'm poor :(

     

    Remember that you'll need a PCI-E SATA adaptor to add a 7th port though (6th is provided via eSATA port on back).

    The drive that came with it is pretty fast, I think.

     

    I'm considering Dremeling out that part below the 5.25" bay to add another 3.5" drive, but I'll probably wait for the warranty period to end:

    How'd you get all those power connectors up there? Just daisy chaining Y splitters?

     

    And did you have to modify anything to get the 3.5" drive below the optical bay? Right now I have two 3.5" on top of it and a 2.5" stuffed in there, but it would be awesome to replace the 2.5" with another 3.5".

    I'm running preclear on a new WD20EARS drive that I just received. I have the jumper placed on the 7-8 pins so the drive should be in compatibility mode.

     

    The speed of the "Copying zeros to remainder of disk to clear it" is jumping around a ton--I've never seen this with a drive before. Usually my clears (on 1/2TB EADS drives) start off at around  90MB/sec and gradually slow down as the clearing progresses.

     

    With the WD20EARS drive (the first of this kind that I've ever used)...the speed is jumping from around 250MB/sec (which seems TOO fast?) to around 3MB/sec.. Is this normal? Does this indicate something is wrong with the drive?

    Just checking since you didn't mention it and these are EARS, did you jumper pins 7-8 prior to preclear?

    If not, you'll probably need to preclear them again after putting the jumpers on and BEFORE adding them to your array

     

     

    Thanks Graywolf,

     

    Yes, already have the the jumpers in, so now the fun can start!

     

    Wow, so I have a bunch of the WD20EARS drives and I've never jumper'd the 7-8 pins. Just noticed on the top of the drive it says "Windows XP, set jumpers 7-8 prior to installation or use WD Align SW". So is this really necessary for Unraid? I don't think the drives even came with jumpers.
