Seagate ST31500341AS 1.5TB

Sold as new with a 5 year warranty? Would be an interesting take. If they never put H on a drive in the factory, why would they print the label too... It does not discclose refurb anywhere either

Yeah, my drives from Amazon are H as well and it's on the label.

4 drives purchased, 2 have failed with greater than 200 re-allocated sectors, 1 failed to the point of where it was marked dead.

On the other hand, I have a CC1J drive that has been running now for 134 hrs, with not so much as a hiccup. It has 0 sectors re-allocated, and appears to be like a rock.

The first drive I bought, a CC1G was running in a USB enclosure until today when I managed to update it to CC1H, and it will be used to replace the newest of the 4, one with 36 hours and 258 sector re-allocations.

*sigh*

The one that failed completely is on its way back to the egg, hopefully to be swapped with a shiny new CC1J that works as well as the one I have. It was also a CC1J though.

Not sure what Seagate is up to. I have had nothing but rock solid drives from them for decades, now 2 out of 4 are having problems for me, and they are lowering their warranty on new drives. I have lost no data, due to my always having a backup plan, and will give these drives a couple more shakes, but there will come a time when it will be time to move on.

Maybe this is all due to the extra precision and heat requirements of a 4 platter drive?

Seagate did just announce several new 500 GB per platter drives, starting the 7200.12 series, so maybe we'll see a 1.5 TB 3-platter drive soon. And then maybe a 4-platter 2.0 TB drive! ha. Couldn't help myself.

>>Maybe this is all due to the extra precision and heat requirements of a 4 platter drive?

I hope they wait until we're finished beta testing these drives!

In this scenario, can a firmware update be done to the drives without losing the information that is already on the drive? Well, no and yes... Even if we're told differently, I would assume that the data on the drive will be lost, but the array will have all of the data in a degraded mode. So, if I have to update my firmware in the future, I'll pull one drive, update the firmware and reinsert it to the NAS. If the array needs to be resynced, I'll let that happen. Once resync is complete and the array is redundant again, I'll pull the next and so on, and thus shouldn't have any data loss. In any event, I think a full backup of the NAS is cheap insurance. If a drives fails during the resync, or something else goes wrong, you'll have a time consuming data recovery project on your hands. Exactly. That is what I do anyway. I keep a mirror off-site of all my data. I've had the ReadyNAS fail and lose all my data even with approved drives. Ironically, I've had a 100% failure rate with my disks in the ReadyNAS. Every one of them has failed at least once. My off-site mirror is running a 6-drive spanned array with no redundancy, and has yet to have a single drive fail in 2 years. Amazing. oh well. I'm using the 1.5TB drives now and they are fine. I'll go with them because I want the space and Seagate is the only option for 1.5TB drives right now.

Yeah, I got this line of BS as well...and also backup all 4TB of my data elsewhere... ya gotta do it, you never know what might happen.

Which speed results do you guys get with Drag and drop (average, vista, xp, ...)

I have two installed with CC1H firmware version and only get an average of 20 MiB/sec write (with performance set to max, without jumbo frames) This used to be 40 MiB/sec on my Duo with two Seagate 500GB installed.

Kind regards

anything special you're using for tesitng speed? Would be happy to replicate the same on my side and report results.

I just transfer with Drag and drop in windows over CIFS. Tested both on a wired xp and vista system (same results)
I use DU meter to measure the speed. Where I used to get a fluctuation of 40MiB/sec using the mentioned duo system.

It really 'maxes out' and stays constant at 20MiB/sec when writing to the NV+ with the two CC1H. (Readynas optimized for speed except jumbo frames, same settings as the Duo..)

Tried with different file sizes and types but all show up as a 'straight line' maxed at 20MiB/sec on the Du meter.

Kind regards

Took a print screen to show the Du Meter graph.



These are two large file transfers to my NV+ ,there was no other network load than these transfers.
(Don't mind the dip in the beginning, was my fault)
Look at the constant upload of 21 MiB/sec (can't be seen on screen shot, but believe me that's what it says)
This is on an NV+ (optimal performance settings, except jumbo frames) with two 1.5TB drives fw CC1H.

What are you guys getting with different firmware?

Kind regards
