[Review] Corsair Flash Voyager GT Turbo USB 3.0 128GB benchmarks

corsair_imageFinally I received my long awaited Corsair Flash Voyager GT Turbo USB 3.0 128GB and I immediately started installing my Gentoo dev box becuase I wanted a portable OS. Unfortunately I quickly realized the OS was bloody slow, even the most simple task required lots of time and the login had a few seconds latency. Simple tasks like a portage sync took way too much time, so I gave up and started doing some benchmarks.
 
Corsair promises 260 MB/s read and 235 MB/s write but in the real world you cannot even dream such values.

 
Here is an HD Tune Pro write benchmark:
 

corsair_turbo_hdtune_write

 
As you can see 60 MB/s are far from the promised 235 MB/s, but what really astonish me is the access time: 720.1 ms.

720 ms access time and a 0.1 MB/S minimum rate.

I did some more benchmarks comparing the Corsair GT Turbo with an OCZ Vector SSD and a Samsung Spinpoint F1 traditional hard disk:
 

corsair_turbo_crystaldiskmark

corsair_turbo_hdtune_read

 
I don’t know how Crystaldiskmark reached 233 MB/s in the sequential write test while HD Tune Pro reached only 60MB/s

Flash drives are still too slow to accomodate an OS and I will have to rearrange an X25-M 80GB to get decent performance.

Thanks Google, no more CalDAV / CardDAV APIs

no_googleI just noticed that Google will drop the CalDAV and CardDAV APIs. Back in December I had been glad when I heard they would drop the ActiveSync protocol because I thought they wanted to promote open standards instead. I was wrong, it seems they just want to impose their useless Google Calendar API. Google services are now dead for me and I suggest you to do the same.  It’s time to promote this awesome project called NOGAPPS which allows you to sever ties with Google even in your Android phone.
