[OS X TeX] Fusion drives and typeset speed

[Richard Seguin]

You mean that a fusion drive is more likely to fail and/or if it fails it’s more likely to fail catastrophically?

I would feel better about a pure hard drive setup if it were operating at 7200 rpm. It’s possible that a local independent authorized repair place would be able to replace the hard drive with a faster one without negating the warrantee.

From the users’ point of view, everything is stored in a single hard drive, and the users never know exactly how the datas actually being stored and moved.

The non-fusion drive is 5400 rpm, and the hard drive part of the fusion drive is also 5400 rpm. I don’t know if all those TeX files wind up on the 128 GB SSD part of the fusion drives. I would probably load one up with 16GB of RAM which in itself makes a big difference with some applications, but I’m not sure about TeX. (The other important app is Aperture, but that’s a question for another group …)
