ITunes encoding: 449.7 seconds (USB SuperDrive) IMac 27-inch, 3.2GHz quad core Intel Core i5, late 2013 Its in-built speakers can't match a pair of quality external speakers, but they compare extremely well next to those offered by other monitors or all-in-one computers, and the new wireless ac compatibility brings faster, more stable WiFi networking to those with a compatible router. The new screen offers excellent color reproduction and viewing angles, and it's a lot less reflective than pre-2012 models, which is important if you're working in an unevenly-lit room. Although, you could alway use it on your next Mac.Whatever the components and clock speeds, the new iMac is also gorgeous to use. A TB3 SSD would be much faster than the USB SSD, but a lot more expensive. There are other external options for your iMac that are faster, but probably not worth the investment. Not a big deal if this was just to get your by for a few years til your next Mac or until you got around to installing it internally. This could lead to slower speeds later on and shorter lifespan for the SSD. The biggest downside of using USB versus internal SATA besides the slightly lower speed is that there is no TRIM support for USB drives on MacOS. Overpriced when you can get a SATA SSD and enclosure for much cheaper, and have the flexibility to use that SATA SSD internally if you wanted. I wouldn't do something like the T5 unless you already had one sitting around.

It is cheap, faster than your HDD, and gives you the option to one day swap it with the HDD. That is one good thing about just using a SATA SSD and a USB enclosure. Click to expand.If you end up removing the internal HDD, you might as well just up a SATA SSD in it.
