Not sure how interesting, but here it goes :bigsmile:
My 2 month old 1650, (Manuf: Feb 2006, shipped with BCDC) installed in a Vantec USB enclosure, shows speed dips at 8x and 8x P-CAV. All other f/w show the same speed dips.
Last week I got another drive, this time a 1655 (Manuf: March 2006, shipped with BCGB) installed in the same enclosure, shows speed dips ONLY at 8x P-CAV. Ok, cannot compare different drives with different f/w.
Today I received another 1650 (Manuf: March 2006, shipped with BCFC) to be installed in a friend's PC. I put it in the same enclosure to test it. Burned a disc and then scanned it, no speed dips at 8x !!! (didn't test P-CAV ... woops)
I also noticed that the older 1650 (Feb 2006) makes a very low squeak/screech when WOPC and/or SB (not sure which) kicks in. The new 1650 (March 2006) doesn't make that noise.
Is there any hardware difference between the two? Just a coincidence?
All 3 drives are perfectly functional, so it's not that one of them is bad. And all 3 came from newegg, if it matters.
I am going to test and swap drives around a bit more and see if I can make anything of my observation. Or maybe I am just too bored :iagree: :o
To bad I only have a laptop at the moment and only one enclosure to test with.
Now I need to find something to burn
