Very good I have upgraded mij macbookpro 2014 with a 2 TB SSD from OWC.The quality and performance is excellent. Also The support and info on the producer's website is excellent.

Bought a 16TB raid to replace an aging… Bought a 16TB raid to replace an aging Drobo. On installation, OWC renamed my existing Drobo and initialized it, causing me weeks of headache in restoring the data.

No longer on our approved vendor list… No longer on our approved vendor list for a number of reasons ranging from poor quality products and poor customer service. Most recently, ordered a computer shown on their site and it took them about 1½ days to contact me to let me know they did not in fact have it in stock nor did they have an equal replacement. Far from it. Further, because of this experience I had to source the product elsewhere and not only did I find it for considerably less, but it also included an actual warranty with teeth and length, and the routine things one expects with buying a desktop, i.e., mouse and keyboard, which their unit did not. Going back still further, we have purchased a number of OWC branded HDs and they seem to all suffer from the same early failure rate, leading me to imagine they are using inferior grade drives. All of this coupled with a number of unpleasant to rude customer service experiences leaves me to conclude this is not a AAA vendor.

Excellent gear but NO SUPPORT… Excellent gear until something goes wrong. Support is understaffed and cannot help in any relevant way - you are left to your own devices. I purchased several of their most expensive thunderbolt docks, and neither had gone wrong in the past until one failed. It's a basic software/driver glitch, but they have been unable to resolve it for two months. It seems like they're on a 30s-per-ticket quota. They disqualified themselves as a provider of professional equipment. If you rely on these devices in a professional environment DO NOT BUY, find a compatible alternative, pay more and save money and time on support.

Horrible horrible experience today Horrible horrible experience today. Be aware of the "Parallels discount deals and their deals in general". It's very sleezy, bait and switch marketing. I purchased a hard drive through the Parallels promotion that I ended up not needing (unopened). Not only did I have to pay for return shipping, I was only issued half my refund because they worked the sleezy promotion into the equation in which I was still forced to pay for the digital software that I will never use.
