Trying to speed up the SATA Bus will not provide any real-world performance increases for Rotating Drives.Įven MOST common SSD drives are not bottlenecked by SATA 2. None of the SATA Busses is a bottleneck for consumer Rotating drives you can buy today. Most Rotating drives available today, whatever their SATA spec, can source data off the spinning platters no faster than about 125MBytes/sec.
SATA 1 is rated at 1.5G bits/sec, which is theoretically about 187.5 Meg Bytes/sec SATA 2 is rated at 3G bits/sec, which is theoretically about 375 Mega Bytes/sec SATA 3 is rated at 6G bits/sec, which theoretically is about 750 Mega Bytes/sec So there will be no real-world difference in where you attach those drives. At this writing, these are almost all quite a bit slower than the Busses available. In this case, that is the speed at which the data spins under the read heads, or the access time of an SSD. "A chain is only as strong as its WEAKEST Link", and a drive is only as fast as its SLOWEST connection. As long as the connection methods are faster than the Drives, there will be no appreciable slowdown.Īll single rotating and SSD drives available today and most Arrays are MUCH slower than SATA-2, PCIe, or ThunderBolt, so there will be no real-world slowdown. Put the top cover onto the bottom of the Mac mini and press down to reattach the clips.The way to think about drive speed is Bottleneck Analysis. Remember to squeeze the clip on the top right post when putting the antenna in place. Next put the antennas back in place on top of the posts. Place the three springs on top of the antenna posts at the bottom left, top left, and top right of the device. Reattach the ribbon cable to the back of the disc assembly at the top left of the assembly. Remember the slightly longer one goes at the bottom right. Replace the screws you removed from each corner earlier.
Once you have installed the new hard drive you can set the disc assembly back in place. Gently reattach the temperature sensor to the new hard drive.įinally replace the four screws that hold the hard drive in place. Next place the new drive into the assembly and slide it onto the sata and power connectors. Remove the anti-static cushions from the old drive and affix them to the new drive in the same location.
You can then slide the disk drive forward to unplug it from the sata and power connectors. Gently remove the temperature sensor that is taped and glued onto the drive. Turn the disk assembly upside down and remove the four screws holding the hard drive in place. Set the screws to the side then lift up on the disc assembly to remove it. Please note the bottom right screw is slightly longer then the rest. There is one screw at each corner of the device. Next we will remove the four screws holding the disc drive assembly in place. The connection is located at the top left of the assembly. Gently disconnect the ribbon cable from the back of the disc assembly. Don't forget to remove its spring as well. To remove the top right antenna you must squeeze clip under it then pull up on the antennae to release it. Remove the spring under it and place it to the side as well. Remove the top left antenna by gently pulling up and setting it to the side. There is one at the bottom left, top left, and top right of the device. Inside the cover you will see three antennas labeled with orange stickers. Once all the clips have been loosened you can flip over the Mac mini and pull the top cover off.

You will hear a series of pops as the clips that hold the cover in place detach. Insert the putty knife between the upper and lower case and work your way around while prying outward.

Unplug the Mac mini and place it upside down on a static free work surface. To perform these steps you will need a putty knife and a #00 Philips Screwdriver. The mini takes a 2.5" sata drive such as the WD Scorpio Black 320 GB 2.5 Inch SATA II Hard Drive.
