2TB drive options for Linux Software Raid

I'm trying to build an Ubuntu Server box primarily for media streaming/file serving and some light development. I'd like to set up a software raid 5 array with 4 or 5 2TB drives. However, I can't tell which drives are able to do Raid and which are not (this is after following the boards and newegg reviews).

It seems that the Western Digital (EARS) and Seagate green drives are NOT raidable. Samsung F4EG's are raidable but there is a limitation due to CCTL as opposed to TLER. Hitachi 5k3000's are good to go (is this true for software raid?).

I'd appreciate any drive suggestions or user experiences. Thanks.
 
You generally do not have to worry about TLER in linux software raid. I do not have any drives with TLER enabled in my 12 to 15 linux software raid arrays at work.

Hitachi 5k3000's are good to go (is this true for software raid?).

This would be my current recommendation. That or their 7200 RPM variants.
 
Thanks for the response. If TLER is not required for software raid, does that mean any drive can be used in software raid? (i.e. Western Digital WD20EARS would work)

If the above is true, why do you in particular recommend the Hitachi?
 
Yes, I'm using two of the EARS drives in RAID1, and definitely, TLER is not needed for software RAID.

TLER is essential for FakeRAID and cheap hardware RAID controllers only.

Honestly, any HDD will do just fine in software RAID.
 
I use Seagate 7200.10s, 7200.11s, WDC black drives, 250 GB WDC SATA1 drives and 2TB hitachi drives in linux software RAID. I have not enabled TLER (CCTL ...) on any of them. The only ones that cause problems are the Seagate 7200.11s but I do not think TLER would fix these. 7200.11 drives have a habit of going totally offline (forever not the reason for TLER) when they hit an unrecoverable block.

With all of these different drives I prefer the hitachis.
