I have a choice to make: from work, I can select either a Kingston 64GB SSDNow drive or an external HDD with similar value. Currently, I use 7200rpm in two unibody MBPs and I have a pair or eMacs with their original drives. Here are my options: 1. SSD in 13" MBP with Windows running on Parallels. I worry that by allocating half of the storage for both OS, I wouldn't have enough space for anything in terms of working with files. Removing the optical drive is not an option here. Also, I need to switch off a few options in Windows, like the disc fragmentation and so on. What are they? Can TRIM support under Parallels be taken advantage of? I'm still not sure about using SSDs. I don't mind waiting for applications to launch or to boot up. 2. SSD in external HDD enclosure with USB, so I can boot from it on both MBPs. In this scenario, it would only run Snow Leopard. But wouldn't a USB2 port impose a bottleneck, almost defeating the point of using an SSD? 3. SSD in eMac with or without an additional HDD. I have a few unused IDE HDD drives, so if I start upgrading my old eMacs, I can put the SSD in an optibay with Tiger or Leopard and put media files on a newly installed HDD. But the joy of having these old eMacs is that they are not worth anything but provide some basic use. I realise that even a 32GB SSD might be an overkill for these computers. Maybe I should just install one of my 7200rpm IDE HDDs and increase the RAM from 1GB. 4. I can choose an external HDD. I already have two with media files and a few backups, but they are messy. I could get a new drive and keep that for Time Machine, slowly organising media files on the other ones. 5. I can just sell the SSD or external HDD on Ebay and live my life as I have been. I might surprise myself with something else from the money. I could get a second-hand Teac or Denon micro Hifi for my office. The current separate system sounds wonderful, but I hate the cable mess and I'd rather enjoy good sound when I'm not working. What would you do? What would Jesus do?
