Western Digital AV-GP 3TB Review Discussion

Recommended Posts

Western Digital already sells a wildly popular 3TB Caviar Green consumer hard drive. They've expanded their green drive offerings to introduce a version specifically for audio and video applications, including DVRs and video surveillance. Today we take a look at the new AV-GP 3TB and find how it's different than the Caviar Green it shares a bloodline with.

If it was 5200 rpm, WD would be lying by saying "between 5400 and 7200 rpm". I guess it's rather a constant 5400 rpm.

The 3TB AV-GP is middle of the pack here' date=' offering reasonably low idle power numbers. The good news is that the drive doesn’t have high or even above-average power consumption by any stretch of the imagination. It is noticeably lower than the company's own Caviar Green drives.[/quote']

Only if you compare it to the older WD20EARS. THe current 3 TB Green has noticeably lower idle power usage and similar load power usage.

Overall I think the firmware tuning on this drive is impressive. I wish WD would offer owners of the regular desktop model the option to switch to this firmware. Never mind the idle power consumption in a desktop. And they could still charge more for the AV version due to extended warrenty (which they would have to provide in this case) and some 24/7-mumbling.

@ETA, you very well might be right. I compared the sequential transfer rate speed of this drive with some benchmarks of the Hitachi 5K3000, 2TB. Both have 750GB/platter, the 5K3000 2TB spins at 5,940RPM, but the STR speeds are very close to the same. So this Caviar green might be closer to 6,000RPM than to 5,000RPM.

And if you test/use it long enough, you will eventually - after maybe a month or two - figure out that this drive silently corrupts data, and the only hint is changing MZER SMART parameter. The error is quite rare, but when it hits - it hits hard, especially if you have RAID-5 or -6.

Finally, someone with solid knowledge. The review did not mention anything about the HDD's "Reliability/Data Integrity". To be specific, its "Non-recoverable read errors per bits read" which is "<10 in 10^14" compared to the usual Green HDD which have "<1 in 10^14". This means that this drive will possibly show a read error every 1.25 Terabyte of data read, compared to the usual Green HDDs (WD30EZRX) which will have a error once every 12.5 TB of data read. So this drive has a greater data corruption rate. This is a 3TB HDD itself so it will have 2 data read errors resulting in data corruption, if it has to be read once completely. So it it bad for backup purposes and use as a desktop HDD. It was never meant to be used as a desktop HDD.
