parity build with SAS drives (SOLVED)


Recommended Posts

Question I just picked up some sas 8tb drives due to price. More specific HGST Ultrastar He8 HUH728080AL4200 (0F23651) 8TB 7200 RPM 128MB Cache SAS 12Gb/s 3.5" Helium Platform Enterprise Hard Drive.

 

Unraid recognized it no problem. Im only trying one out. Due to it being a big drive I have to use it as parity. Its hooked up to an LSI 8i.

 

Now the issue my parity builds (used) to range in the 90-100s. Now After adding that drive its almost exactly half 48ish. I deleted all my older drives the (2TBs ones) no change. So two questions.

 

First is this due to it being a SAS drive? I thought there 12gb shouldnt that be faster?

 

Second could this be due to a huge range in harddrive size maybe? one 8tb sas (4) 3tb seagates?

 

Or maybe cause it's a 4k? And all the others arent?

 

 

I know sometimes it can range so Ill let it run a few hrs tomorrow when im at work.
