I've got my eye on a pair of these, but will wait for some failure-rate data.

Question Slower is better on access times?

Gabriel:

Either your chart is mis-labelled, or else you interpreted the results bass-ackwards for the access times. The Barracuda Green had the SLOWEST access times by 10% over the Barracuda LP. It was virtually identical to the Barracuda XT; not 10% faster.

Default Missing Details

Gabriel,

A few details are missing. How many platters? Power burn while idling and moving data? Data transfer rate media to buffer?

Thanks,

Orville

Ops, you are right! I'll fix this as soon as I find a decent Internet connection. Thank you so much for pointing this out!

Platters: I sent an email to Seagate asking this. As soon as they reply I post this information here.

Power:
Average idle power 4.5W
Average operating power 5.8W

Compare these to the Barracuda XT:
Average idle power 6.39W
Average operating power 9.23W

Data transfer rate media to buffer: I don't know how to measure this.

Thanks,
Gabriel.

Default Response

Gabriel,

As long as the buffer to computer data rate (SATA rate, 6Gb/s in this case) is much greater than the media to buffer data rate (media rate, usually less than 1 Gb/s), the media to buffer rate limits the media to computer rate at the media rate value. The media rate should be measured for transfers with the head positioned on the outside track (faster) and on the inside track (slower) to completely describe the drive.

I was surfing early this morning and came upon this PDF file at Seagate:

http://www.seagate.com/staticfiles/s...100649225c.pdf

It is titled Product Manual-Barracuda Green: ST2000DL003, ST1500DL003 and is dated March 2011. In the specification section of the manual, the ST2000DL003 is stated to have three platters and six heads (667 GB/platter). This would be very nice for someone looking for an HDD for use in a moderately sized movie NAS since the heat would be as low as is possible. However, some doubt exists in my mind because the ST1500DL003, described in the same manual, is also listed as having three platters and six heads (333 GB/platter). Seems just a hair screwy to me. How about seeing what Seagate says about the “Product Manual”?

One more thing. I came upon this while surfing this morning:

http://www.mwave.com/mwave/SKUSearch...iteria=AA78170

The savings is small, only $6 less than NewEgg, but every little bit helps if you are going a fat RAID 5 NAS.

Orville

P.S.

Now that Seagate has Samsung HDD in tow, when they are going to get off of their ass and bring out a 4T (1GB/Platter) 5900 RPM drive. That's the one I'm waiting for. In the meanwhile, I'm concentrating on the SQL database.

Seagate replied to my email saying that this hard drive has four platters.
