Hello - In December I purchased a 27" iMac with 512gb SSD. I noticed that my Seagate 3TB USB 3.0 drive that I have connected goes to sleep randomly and when it wakes up, the drive takes a couple seconds to spin up and seems to slow down everything while its spinning up. I noticed that I can change the hard drive sleep setting here: http://www.thexlab.com/faqs/harddrivesleep.html but will this do any damage to my SSD? Is it OK that the SSD never goes to sleep? Are there other settings I should be looking into? Thank you!
