Yeah DBAN is good. Been reading about it online for testing my drives before I put them in nas4free. Do you test in/out/read/write speeds too? I'm curious Emulsifide, do you test multiple drives at the same time, or just one at a time? I usually just open up HDsentinel and it shows my SMART status and health right away. I can also do short and long tests if I want to. HDsentinel is Windows though. Haven't looked to see if it is available for other OS'es.
I did some read tests in the first post of this thread. As you can see in the video I made in post 146, all of the lights are blinking on the two chassis because I'm testing 50 drives at a time. Throughput is 1500MB/sec.

Ok, you use a wipe tool for checking your disk. it's a way. Maybe i will try it.
For now, i'm using only smartctl & badblocks
Thanks.

The other 14 arrived today and like the first 10, they're all perfect. :)

Striped the 14 together and got this.



Then I striped all 24 together and got this. So somewhere below 14 something is maxing out. Probably the controller?

Very nice numbers! Even at 14 drives, these things are screamers. If you're using the SAS expander on the CSE-216, you're probably maxing out the 4 SAS channels you have attached to it. Drop it down to 7 drives and see what happens with the same benchmark.

The 2nd batch of 50 drives is cooking right now. So far, I'm 30% through my mass extinction of data on batch 2 with zero errors.

These things are going to RIP when I have them in the ceph cluster!

...if anyone is interested in a couple of ghetto sequential read/write benchmarks of a 12 drive raid0 stripe volume. The DD write to tempfile2 was pegging a core at 100%, so it may have been CPU bound (single thread):

Code:
[root@nas3 extra]# dd if=/dev/zero of=tempfile2 bs=1M count=163840 conv=fdatasync,notrunc status=progress

I'm looking to save freight costs to Australia for 24 or 36 drives.

Anyone been able to purchase these drives without the caddies?
If so, how well was the drives packed on their own?
Would I be better to purchase with caddies for better protection and foam packing?

Many thanks in advance.

Having troubles purchasing. Paypal just returns my payment without any description. Have anyone had the same troubles?

Does your shipping address match your banking address? There has been some fraud in recent months.
How many were you ordering? Perhaps try again at a later time?
Cheers

Can anyone report back on what the lowest this seller took for quantity? Looking to get 24 of these to fill a C6100.

I had a 24 disk for $15 each bid - they sat on it for two days and let it expire...
...that is their modus operandi... You can always call them and let them know that they've been neglecting their ebay account... however they might assess an asshole tax for bugging them with an $16/per price :)

They seem to either miss some offers and just outright decline or accept others. I have a few ebay accounts I spam them with at different hourly intervals to make sure they see at least one of them.

Just used a spare paypal account and everything worked. Ordered 24, waiting for their arrival.
