Seagate ST31500341AS 1.5TB

I just did a chat with Seagate, FYI:

Jared J.: At this time we currently don't have a firmwareware update for the drives we have a pending update that should be available next week
darwin: ok
darwin: as far as I've heard, there have been updates
darwin: but is the pending one actually supposed to fix the problems?
Jared J.: correct
darwin: so the SD1A and CC1J don't actually fix the problems these drives have?
Jared J.: no they fix the drive as well but we don't have that firmware to send out til next week
darwin: ok, that's odd, someone a few days ago sent me the link for those, but that doesn't help the other 2 drives
Jared J.: i understand but we don't have access to the firmware anymore because of the pending update
darwin: ok
darwin: thanks
Jared J.: have a good day
darwin: but it will be coming out next week?
Jared J.: thank you for contacting seagate
Jared J.: yes
darwin: ok, I'd rather not have to send the drives back :)
darwin: thank you

Weird conversation...
Hope next week release will solve the performance issues... :roll: :nashammer:

I'm not really concerned about performance issues, they should be fine in the ReadyNAS Pro Business I ordered this week. I just don't want them to start failing/losing data.

Why am I seeing a constant max write performance of 20MiB/sec with two of them installed in an NV+ (optimized for performance) this used to be around 40 with two 500GiB drives installed...

Gotcha. My NV (non plus) with 4x 750GB hits about 40/sec right now over gigabit. I guess this is why I'm setting up the new one from scratch before migrating anything over. I really don't want to have to stick with the 750GB's until the 1.5+ drives get ironed out.

So after a bit of a rollercoaster ride I now have my ReadyNAS with 4 1.5Tb Seagate ST31500341AS drives installed (3 x SD17 firmware upgraded to SD1A and 1 x CC1H )

The good news I've seen no signs of stuttering or hanging since expansion. I've just watched a movie while copying other files with no issues.

The only issue to date had been one Reallocated Sector on disk four less than 24 hours after expansion.

Yeah, I had one reallocated sector on one drive and now another with two reallocated sectors... They seem to creep in slowly... No alerts at them, so maybe a small number of them are OK. I'm going to leave it be for now. If they jump up dramatically, then I'll RMA the disks.

Of four drives, I have RMA'd two due to excessive reallocated sectors. The other two though are holding rock solid at 0, with no other errors being reported either.

Would you mind posting the batch/part number for the drives that worked and the ones that had to be RMA'd?

Unfortunately, I do not have that information readily available. The two I sent back, that I should have recorded the information from, I did not, and the other two are my live drives in the NAS. All I can tell you is on of the good ones was factory CC1J and the other was factory CC1G that I upgraded to CC1H. The failed drives were one each of CC1J factory and CC1H factory. I know that does not tell when they were made, or what group they belong to though.
