In 2010 when I got my Mac Pro, I did so because every single external drive enclosure that I could find featured the same problem: failure-prone ports. This is just an example. But you can see how ports are made on these drives. The port is soldered onto the circuit board, but every time you plug or unplug it, mechanical stress transfers to the solder points. Eventually they break and it no longer works. Just google the terms, "external hard drive port failure"... and see the carnage. Then there are the crappy power supplies that every external RAID system uses. Just google "drobo power supply failure" and "lacie power supply failure" and "g-tech power supply failure"... Then there is the COST of external enclosures. My Mac Pro (used) ran me $2600 (including a monitor, hard drives, NVIDIA 285 GTX, NVIDIA 120 GT, AppleCare for 3 years, and a 24" LCD that was a $500 monitor). What are the options for an external Thunderbolt enclosure capable of hosting six SATA drives? (Yes I use all six bays in my Pro.) The stuff I'm seeing is ugly, probably very loud fans, and I have no way to know if the engineering and parts quality is anything like a Mac Pro in terms of the power supply, ports, etc. None of the products I'm seeing have 5.25" optical bays. And all of them are at least $700 WITHOUT the drives. And if an external bay fails you can't just take it into Apple for AppleCare treatment. You have to deal with "whoever." I bought my Mac Pro so as to avoid having to rely on external drives for my primary storage (of course I still backup to an external drive and archival BD-R discs). Now what option will Apple give us for an enclosure so we don't have to rely on some Chinese-made garbage with loud fans and ports and power supplies that fail randomly?
