everything completely for conversion to SSD

HDD XBench 31.67 (in advance)
XBench SSD 207.85 (after)

Although my Macbook (4.1) only has a SATA I interface and the SSD (Samsung 830 series) has SATA III, the speed is enormous.
The hardwrk-PATA adapter kit was already after 1 day with me and the attached manual is very good, only the images (black / white) are sometimes too dark but there is the same description on the website hardwrk with color images. I had looked at changing a YouTube instructions for SuperDrive for security and in the description of hardwrk custom one less two screws unscrew. They know what they have described in the manual, a good thing. It took me so about 1 hour for installation. The SSD is at the location of the HDD. The HDD is inserted into the Optibay and installed in place of the SuperDrive and SuperDrive installed in an external enclosure. Then copy still about 2 hours to all data on the SSD and the DVD player (software) or Etject button to adjust as it stands on the hardwrk website.
A tip: The best a Time Machine backup recoup what you've done before. Then everything is as before. Only the SuperDrive is now externally.
A small note to the external SuperDrive enclosure: the screws were too short but to demand the support of hardwrk were the next day because the correct screws. The support of hardwrk is super good, you get in a very short time to respond to all inquiries.

In retrospect, I arrive to another consideration because the prices of SSD's are dropped if one does not equal buying an equal SSD and uses this instead of the old HDD. Nor is it so complicated to replace only the HDD by SSD.
An example I paid for the Samsung 830 SSD 128GB 138 Euro and 79 Euro for the PATA Adapter Kit = 217 Euro. (My HDD is 256GB in size)
Now you get the Samsung 830 SSD 256GB for 217 euros. And you have the SuperDrive then still internally. Of course I have with 256GB HDD and SSD 128GB more storage space but I would get along with 256GB.
Conclusion: The hardwrk-PATA adapter kit is in my opinion a bit overpriced but for the money you get everything completely and with great support.
