Please excuse my english, i am spanish.
Let me begin by saying that this disks performs amazingly well.
My Mac Mini shines with this disk. I have never used something as fast and soundless as this.
The only thing that worried me, was the firmware version. I saw that this disk has 2 firmware versions, the 1711 and the 1571 (older). Apparently the newest one made it pretty unusable if you were running Windows 7 (not my case), and made the computer jam if you put the disk to sleep.
On Crucial website, you can fill a form and return the disk (if it had the 1711), and they send another disk with the 1571.
Since i live abroad, it was pretty complicated, since i had to pay for the shipping myself.
Nevertheless this drive came with the older firmware, so i guess i was lucky.
Beside that, it all worked like a charm.
If i would have the money, i would probably buy the 128GB version, since 64 is not that much. I keep this as the main bootdisk, and i have nearly 30GB free. All my music and movies are kept in an USB external drive.
Once again, excuse my english.
