If you need a SSD for the operation of the hardwrk-SSD/HDD-adapter kit, we recommend the following models.
Our experience shows: Better a slower brand-name SSD than an "overbreed" Noname- or special-manufacturer-SSD. Malfunctions, slow speed up to total breakdown can be on the daily agenda with those.
For all MacBooks/MacBook Pro Older than 2011. These modells do not have a SATA III connection, so a SATA II disk is sufficient. The performance, longterm stability and the just fair price of the Intel 320 are ideal for your MacBook Pro.
For all MacBook Pro since 2011. Samsung's SSD 830 really is first class. In most domain it reaches the levels of the top dog, the much more expensive Intel 520. Who got the change for the extra quality goes with Intel. Who prefers a good value for money should choose the Samsung 830.Both SSD's will deliver rocket-speed and lead the field for high-end SATA III SSD's.
For the use in MacBook Pro's we recommend the silent Hitachi hard disks (500/750GB)which are often used by Apple as well. Who needs more space should consider Sasmsung or Western Digital, which offer up to 1TB of space. This often means more noise and more power consumption, so you should think well if you really need a 1TB hard disk in you MacBook Pro. Our tip: rather use a 750 GB hard disk with 5.200 RPM, than 1TB with 7.200 RPM. The SSD/HDD combination will already speed up your MacBook and, in most cases, you will not notice the faster HDD speed.
