Looking at drives today.

Local supplier had 5400rpm Samsung but they had on sticker "Advanced format"
Same for the WD green5400 rpm.
They also had Seagate, and Hitachi available in 5400 or 7200 rpm.

What is recommended for this NAS?  Don`t want to buy 3 or 4 incompatible drives.

I can't speak to RAID 5, but I've been using 8 Seagate ST32000542AS (non-AFD) formatted as Standard Volumes on my two DNS-343 for almost 3 years without one HDD related issue. These drives are still available from a couple of vendors on Amazon. I can't say how they will behave under RAID 5.

What brand/model HDDs did you end up purchasing?

[roflcopter666]

Just formatted 4 x Samsung 2TB in raid 5, ext3.

Copying data back across now, shall see how we go..

What model numbers are you using? A number of other users are also trying to determine which HDDs are stable in RAID 5. Please post how your configuration behaves in the short/long term.

Samsung HD204UI S2H7J9AB7xxx
5400 RPM
Firmware version 1.05beta

Raid 5, ext3 running 4 x drives now.  Shows 5.9TB total avail space once formatted.

Transfer rates are similar to WD green 1TB drives that had before. (~8-12MB/s r/w) - slow performance likely limit of hardware + raid5 + ext3

No issues so far, still transferring 1.8TB data back to NAS.
