While the Retina Pro and the latest MacBook Airs sport new MagSafe 2 connectors, the 13-inch Pro (along with its 15-inch sibling) still has the last-gen version. Most of those connections, including Gigabit Ethernet, Thunderbolt and the SDXC card slot, are crammed on the left edge of the machine, with the slot-loading optical drive occupying the right side. The latest system ships with two USB 3.0 sockets (up from USB 2.0), but otherwise you're looking at a very familiar selection of ports. Those who salivated when Apple revealed the Retina model's 0.71-inch-thick, 4.46-pound body may be unimpressed by this guy's slightly beefier profile, but the Pro looks as polished as ever, and is definitely compact enough that toting it around shouldn't be an issue. The dimensions and weight also remain unchanged: the 13-inch version tips in at 4.5 pounds and measures 0.95 inches thick, while the new 15-inch Pro weighs 5.6 pounds. The SATA cable is the weak link, one of many reasons Apple went to the PCI-e and soldered-in storage.The latest MacBook Pros look nearly identical to their 2011 predecessors, with the same aluminum, unibody construction, backlit, island-style keyboard and glass trackpad. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion. Those SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. As it cools down, electrical contact may once again be restored. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure. In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists.

It is however no mystery why old cables fail when switching from HDD to SSD. Agreed, a new SATA cable is a nominal expense and highly recommended.
