Because Apple prices on upgrading a hard drive are on the far side of rapacious. I've also heard rumors that upgrading internal drives on some of the new macs (macbooks anyways) cannot be done without a soldering iron. In any case, upgrading the HD in my older iMac looked like it would be a major pain. > While I don't have my own experience with Thunderbolt, all other > interfaces (USB 3.0, eSATA, FW-400, FW-800, and even FW-3200) are > inferior to SATA-3 > (not counting SAS-600 which is nominally on par with SATA3) > Thuderbolt is the only one that seems to be exceeding what SATA-3 can do. My understanding is that Thunderbolt is basically an external SATA. I think I posted some tests I did a little while ago that showed my USB-3 SSD outperforming the internal spinny drive. I think the theoretical speeds are 6GbS to the drive and 5GbS over USB 3. > > So, having an external SSD drive (which I would expect to be SATA-3 > drive?) would fully benefit from its speed only if you are connecting it > via Thunderbolt. Are you? He may not be maximizing performance, but he may be maximizing his performance for his dollar. The one thing that does seem to make the new iMac more interesting than just a mini plus a thunderbolt monitor is that in theory it can eventually be used as a t-bolt monitor. > > Igor > > > > On Dec 23, 2013, at 1:55 PM, Stan Halpin wrote: > > > I held off for several weeks, thinking that the Mini and/or > > Thunderbolt displays might be updated when the MacPro was finally > > available, but that didn't happen.
