Apple is building self-branded large capacity solid state drives (SSD) to be used in its next Mac Pro that is set to get a refresh later this year, fresh rumors suggest.

Theo Valich of Bright Side of News, a blog covering the semiconductor industry, found an initial batch of 2TB SSDs wearing the recognizable Apple logo in a Far East supplier factory in China. While we are not able to confirm the authenticity of the report, it certainly sparks a speculation that Apple will include the component into its high-end desktop like the Mac Pro.

"But seeing a 2TB Solid State Drive with an Apple logo on it opens very large ground for speculation. Given that we were not able to learn more about the parts in question, we have to leave it at that. But from the looks of it, the 2TB drives used industry standard 3.5" form factor, full height (just like your regular 3.5" spinning drive) and a SATA connector (not SAS or some proprietary port)," Valich writes.

As Apple Insider notes, if the news turn out to be true, the drives will see a place in the company's high-end desktop category as the new iMacs switched to smaller 2.5-inch laptop drives to save space.

While we are yet to see what the 2013 Mac Pro will be like, it's speculated that Apple might go for a major upgrade for its Mac Pro line-up as it has been more than two years since the current Mac Pro came to life. However, be prepared to shell out more if you ever want to purchase it because as BSS notes "Should a 2TB SSD become a reality in Apple's lineup, the company will be able to offer up to 8TB of Solid State storage per single workstation. Just do not expect to come cheaply."

However, it's not clear at this point in time when the company would release its refreshed professional level tower. It remains to be seen whether it would come in the coming months or later in the year when Intel launches its next generation Xeon processors.

According to an earlier report, Apple is working on a new Mac Pro which it plans to launch this Spring. In a newsletter sent to customers, France Systems, a French Apple reseller, said a new range of Mac Pro will be released in Spring 2013.
