I have not been able to find a document to tell me the maximum capacity that my TeraStatio n HS-DHTGL/R 5 can handle - where may I find out this information please ?
Is there any (possibly open source) firmware that will increase the capacity to 4 * 2TB ?
Thanks.
Not enough power supplied to handle 2TB drives.
Simply NOT true!
Just upgraded TS-DHTGL/R5 running 2.14 with 4 * 2 TB WD green: Raid 5 is verifying atm.
Performance of Webinterface is as poor as with original 4 * 1 TB drives :(
I'm not saying you can't try it, and in some chassis it will work - but we didn't design the electrical system to power 4x2TB HDDs. The power could run under the 2TB HDD spec, or cause a failure later with the 2TB HDDs drawing more power than what is available in that unit. The Terastation Live was released with HDDs up to 1TB each - nothing of larger capacity was tested for compatibility with the electrical system.
Word! Ok, i replaced original 1TB drives with "green" series 2TB hdds. These --should-- consume less power, what could be the reason they were accepted ... atm it´s still verifying the initial build RAID5 ... we´ll see.
As for your advice, i´ll first benchmark and stresstest it, to see if it can provide enough power under load, thx for that hint!!! :)
EDIT:
According to that link: http://buffalo.nas-central.org/wiki/Category:TerastationLive i replaced the drives. I didn´t know larger drives weren´t officially supported ... my fault!
