The disks are functioning well so far. The speed (see photo) is very good for the capacity and dimensions - the price is right. According to the hard disk is not. I would not say it would be the quietest, but bothers me not at all; Moreover, it is very subjective. Since I wanted to obstruct two hard drives, I had to expand my DVD drive. And that disk would not work with a caddy (SATA II or III, tried both). The drive was recognized but could not be used. No matter what I tried. It has been found that the 7K1000 SATA II are converted vice must - and in fact it worked. First, however, the problem was to change the setting. Because the Internet can find some self-starting CDs, but the drivers do not support the Mac keyboard not (who has a USB keyboard - should work - I had the opportunity not). But in a forum I could find another solution (unfortunately I lost the link with the installation, but I have the file yet), this CD obviously includes the drivers and you can relatively easily adjust the settings when it comes to both disks. The second hard drive that has replaced the old one, works instantly - had to be changed. I have exchanged both disks several times to see if the hard drive was defective - both have this incompatibility on. Despite all the effort I do not see it negatively, especially since it worked in the end, and it was the only way 2TB built into my laptop for the price. And who has been building 2TB in a Macbook Pro. Whoever does and has problems, I am happy to send to the file.
