Mac – How to turn off boot up chime on late 2013 mac pro

Yes - three 5K displays are supported on even the least GPU endowed Mac Pro Late 2013.

While I do not have the luxury of owning this kind of a setup, the following coming directly from Apple should answer this:

Mac Pro (Late 2013) - Technical Specifications

These particular Mac Pros use an Apple designed PCIe 2.0 x4 interface. If you're wanting to replace the internal drives your options will be limited.

I would check out the following instructions provided by Apple to determine your happy to proceed. If so, I suggest you purchase your SSD from a reputable retailer. For example, the following are some well-regarded sites:

• Mac Sales
• Simply Mac
• RAM City
• Macfixit

By buying from a reputable store you'll be sure to get an SSD fit for purpose, regardless of manufacturer. Being reputable means they're only going to sell something that works and they'll stand behind the product they sell, regardless of the brand. I would also check out Amazon as well for particular models once you know what you're after, as you'd probably find you can buy cheaper from there.

Another option

If I was you I would seriously consider keeping your current drive and using an external Thunderbolt enclosure to increase your storage capacity. If speed isn't so important, then you could use external USB drives instead.
