<< Heheheh, apparently you haven't read the 60gxp specs, or the 120gxp specs. Page 50, under reliability, says you should run drive no more than 333 power on hours a month (comes out to about 11 hours a day), and that you will get 5 years life at that rate. Do the math, thats 20,000 hours of total life for the drive, barely 2 years at 24/7 usage. For more details and links to the OFFICIAL specs direct from IBM, I put a long post here: >>
apparently you have not been keeping up with the latest news! >>
Let me quote directly from IBM's specs, since apparently you didn't bother to read my long response on the other thread where I mention IBM's response.

6.6.3 Life
Expected product life is 5 years under typical desktop PC usage conditions:
333 Power-On Hours (POH) per month.
Seeking/writing/reading operations to be 20% of POH at 40 degrees C or lower enviromental temperature" >>

Thats a DIRECT quote from page 50 under section reliability of the OFFICIAL IBM specs for 120gxp drives (also on page 50 of 60gxp specs, I'll put the link to the 120gxp here, the other and more info is in the long post I referred to above)

Let me quote the official IBM response to storage review (i.e. the one that the inquirer talks about
"Our "power-on hour" specification represents typical desktop PC usage. It is not an indication of the maximum number of power-on hours. Our customers have clearly used the drive in 24x7 operations successfully. Furthermore, ibm stands by the Deskstar 120GXP's 3-year warranty irrespective of power-on usage."
They claim that is not the max power on hours, perhaps the 333 hours is not the max, but they are skirting the real issue. Like it says in the specs, the "EXPECTED PRODUCT LIFE" of these hard drives are 5 years at 333 hours a month. Do the math, thats 20,000 hours expected life on the drive, about two years if you run it 24/7 and since only 20% of that is activly using the drive with reading/writing/seeking, if you use it 24/7 in a server enviroment that constantly uses the drive 24/7 then you get less than 6 months life (4,000 hours)
