80GB vs 120GB Speed Difference
I like many here have an original MacBook Air (A1237) in which the hard drive has tanked. I have opened the computer and found that the hard drive inside is a Samsung HS082HB/A; 4.2k, PATA, ZIF. Looked on this site and many have replaced it with a 120GB version; Samsung HS12YHA. When I look online the 80GB drive is getting hard to find new. The only issue I have having is that it seems the HS12YHA is a 3.6k RPM drive. Seek and Latency seems about the same, just a tad slower.
My question is has anyone felt there was a difference in speed? iFixit sells what appears to be a 4200 RPM used 120GB HD; also wondering if this is truly 4.2k?
Is this a good question?
