Load Cycle Count ---------- 1100346 ************* Now Over 1 Million **************
I Still have some concerns over the LLC (Load/UnLoad Cycle Count). http://en.wikipedia.org/wiki/S.M.A.R.T.
The typical lifetime rating for laptop (2.5-in) hard drives is 300,000 to 600,000 load cycles.
Unfortunatly the spec page from WD state otherwise. http://www.wdc.com/wdproducts/library/S ... 701229.pdf Load/unload cycles 300,000
I have been running firmware versions
RAIDiator-x86 4.2.17 since 20110508.
RAIDiator-x86 4.2.15 since 20101218.
RAIDiator-x86 4.2.13 since 20100923.
RAIDiator-x86 4.2.12 since 20100709.
RAIDiator-x86 4.2.12-T32 since 20100625.
Before this I would have to search the logs.
