The VR300GB reviews on NewEgg:
http://www.newegg.co...N82E16822136260

Sort by lowest rating, I find this very accurate, out of 12 drives I have purchased all at the same time (bad idea), I have had numerous failures, in almost every instance its bad sectors. I have a similar configuration but with Raptor150s and it has worked fine with only 1 or 2 failures in the past 2-4 years.

For the Velociraptor 300s, I have had a total of:

5 failures from the original disks
1 failure from the RMA I received from WD
6 total failures out of 12 drives

I am really getting tired of RMA'ing disks to WD, I have even opened a case with them in June/July and asked them about premature failure rates, they said they did testing and there was no such problem. However, with all of the comments on NewEgg and all my failures in only 5-6 months, I am not sure I would recommend Velociraptors to anyone.

Comments? Does anyone else have a stack of VR300s? What has been your experience with them?

Justin.

You bought them from Newegg? OEM I assume? :scared:

Were they all packed properly? Newegg, Mwave, Zipzoomfly, Allstarshop, just about every major retailer out there is notorious for improperly handling and packing OEM packaged products. I would strongly suspect that the way most retailers out there pack things is causing a significant jump in failure rates.


Hint: most retails do a single layer, maybe two layers, three if you're lucky, of the large-bubble bubble-wrap around a drive. The drive as packed then goes into the bottom of the box and topped off with foam peanuts. This is entirely INadequate protection as this results in less than 2" of bubble wrap in each dimension. Plus OEM packed products are not actually wrapped in bubble wrap til they hit the packaging stage, which means they go through the entire warehouse in just the ESD bag/clamshell... eek.


I don't have a huge database of Velociraptors here, but we have a few and haven't noticed anything out of the ordinary-- but that said my sample of Velociraptors is very small by my standards as well as the fact that it's somewhat affected by other peculiarities to the products we design/build.

OEM yes and when I ordered I made 12 separate orders, each for 1 drive each, so each drive was shipped in its own box and no drive was DOA (at least to begin with).

Still if you did it all at the same time then they're all from the same batch, and if they were all from a single vendor they were all subject to the vendor's handling (or lack thereof). I would strongly suspect a mishandled batch, poor handling by the vendor (yes, 12 separate drives being tossed individually into the box before packing is just as likely as 12 drives in a single order each being tossed separately), etc.

Mishandling does not always cause DOA. And each drive being shipped individually means each drive can still be improperly packed...

[troubleshooter]

I'm curious; How many hours of runtime (Power_On_Hours) as reported by SMART (smartctl -a) were on the drives when they failed?

The most recent one below, 899 hours, its cute too, notice how there are no bad sectors in the smart statistics, but scroll all the way down and you will see what happens if you try to use the disk, the filesystem becomes corrupted and a ton of disk errors.

Well this is the 9th drive that failed last Friday, I submitted an RMA for this and I am also ordering a 3ware RAID controller to better deal with these problems.

Might you still have a record of the Power_On_Hours from the previous eight failed drives?

[datestardi]

Jpiszcz, something doesn't seem right with the data you're posting, as if something other than the drives in your system (or the test methodology) is causing the errors.

Can you move the drives to a known working system and retest them?

If you test them with Data Lifeguard (you can use a DOS CD if you're not running Windows), what is the result?
