I'm going to upgrade my RAM and HD on my 15" i5 mid2010. It's the 2.4g i5, 4GB, 320GB 5400RPM Hitachi. So I'm deciding between the 1tb WD scorpio black and hitachi travelstar, Both are very similar, 7200RPM HDDs. No real big issue picking one of these What I'm also considering and would like to hear some input from you guys who are more informed on tech than I..... For 20$ more, the new Seagate 'SSHD' "hybrid" drive is the other option. I was all but sold, and figured it couldnt be worse and for only 20$, i don't have much to lose... Then I realized the HD part of the drive is only 5400RPM. I really don't have complaints with the current 5400rpm stock drive, I just want a bit more storage. However since I'm upgrading and upgrading the memory, might as well get what I can in terms of HD performance while I have the computer in surgery. So what will have better usability? A 7200HDD or a 5400SSHD. Aside from just web browsing, listening to music, and email. Primarily the machine is used for viewing video on VLC>Minidisplay>HDMI and various Audio and MIDI apps and DAWs, Logic, Reason, Native Instruments products, etc etc etc. Don't really do any video production, and very little photo editing. Streaming video to my TV and playing my synths through it is pretty much 95% of the use this machine sees.... Whats the better choice here? 7200HDD or 5400SSHD. I don't really want to go with a SSD at this point in time. I know they are the best, but I have my reasons. Open to one in the future for sure, but not now, not on this machine.
