What Does 18TB of Hitachi Hard Drives Look Like?

[Calamar]

As I mentioned in the 10TB post went for 2TB disks, hitachi looks to make some non raid disks many hardware raid power users like:
HDS722020ALA330

The package from Hitachi, the best I've seen:





Two of them came DOA. I returned them, and returned DOA again, due to lack of care in packaging. I'm still waiting my 2 left disks.

The server:
Asus P7F-C/SAS (3420)
Intel i5 750
2GB Kingston @ 667
LSI 9750SA + BBUi7
Promise TX4650



Performance of a RAID6 (write cache enabled) of 7 disks:



Reading from TX4650 (raid5 3TB) to the LSI 9750SA (raid6):


I forgot!
All numbers are with writecache on, rebuild/migrate and verify at full priority (Vs IO) (<-- lowest performance), Adaptative, Intelligent read cache, queueing, storsave: balance.

I highly recommend the 9750, but the managing software is quite confusing, promise software is better, but given his support: drivers/firmware (it took 3 years to make 4650 work properly), email/callcenters( ) I can't recommend their products (I've had some).

Nice!

did i understand correct? 2 of the Deathstars were DOA and the 2 replacements were too?

yeah that is pretty crappy to have 4 bad drives brand new out of the box... Quality control anyone??

Yeap, but because of package. While the first 9 came with the individual box depicted "thrown" inside a cardboard box with any supplemental packaging (touching the bottom of the box) in a 1200km trip not bad 7/9.
The first RMA came even worst: disks inside their plastic bag, in the bottom of a cardboard box, then filled with crumpled cardboard. Thats all.

They paid all 4 of them, so its their problem how they package their stuff, not mine. Today I've received the two new (and final) ones.

Original hitachi package is great, but the vendor's one is crappy...

Nice!

Performance with 8 disks after migration raid6 to raid6 (took 3 days). Now its time to expand the partition.

Curious, is that a Norco?
