Installing a SSD drive into a mid-2007 iMac
I have a
mid-2007 iMac with a 2.4 GHz Core2Duo processor and despite the fact that it is already six years old, it still does a good job. However, compared to a friend's recent MacBook Air with a solid state disk (SSD) it felt sluggish when opening programmes and loading larger documents.
So, I thought it would be worthwhile to replace the old spinning hard disk drive with an SSD, instead of buying a new computer. I still like the display of the iMac. Hence, I got myself a
Samsung 840 SATA drive, as it came with a USB cable and bracket hard drive holder.
It actually wasn't that difficult to replace the hard drive in my iMac. Of course I can give no guarantee that this works for you as well. Here are the steps I took:
So far I am really happy with the new SSD. Applications are opening much faster and overall the computer feels much snappier. It looks like it can serve me quite a little longer.
Here are a few pictures of the

So is it faster for things like reading and writing data in R? The following takes 2.2 s on my old laptop with a good old spinner:
x <- runif(2^25) # Roughly 256 mb of data
system.time(saveRDS(x, file="tmp.Rdata", compress=FALSE))
## user system elapsed
## 0.584 0.332 2.227
Here are the timings of my SSD iMac:
## user system elapsed
## 0.463 0.678 1.137
50 % reduction, pretty good :)
Here are timings on an identical iMac with HDD
## user system elapsed
## 0.477 0.700 5.329
Indeed, it looks pretty good.
