This same guide also worked with my Apple Time Capsule 2TB MC344LLA / A1355 but I installed a Samsung 860 QVO 2TB SSD, It greatly reduced the weight of the unit and there’s less heat dissipation without the bulky standard WD 2TB 3.5 drive.
I’m not seeing a guide for the Apple Time Capsule 2TB MC344LLA / A1355 so I’ll have to see which one is closer to my model when it arrives,
But in the meantime has anyone been able to upgrade the hard drive past 2TB without any issues?
Is a Firmware update needed to do so?
There is a difference between CR2032 and BR2032. While the dimensions are the same, the chemistries are different. The BR2032 are preferred for maintaining computer PRAM or BIOS because at temperatures above 60c (140f) the CR type battery decays faster and has more voltage sag. It is not unusual for the inside of your computer to reach these temperatures. In relatively speaking higher drain applications -like many consumer use applications, the chemistry of the CR type battery is advantageous as it provides more steady voltage under higher drains at temperatures under 60c. In short, after 3 or 4 years in a system the CR chemistry battery might not be providing close enough to the 3v for the system clock to maintain the purest accuracy. But can you use either?- yes. But what does Apple put as factory original? - the BR chemistry.
The PRAM battery is a commonly available BR2032 coin-cell.
By mail order only and from China for me, Ordered two BR2032 coin cells 12 days ago and still waiting. I doubt if you would find this exact type anywhere locally in a store. You could go with a CR2032 which is found more easily but after what I found online it does make a difference.
The main difference between these two types resides in their electrode.
While similar, the BR2032 uses carbon monofluoride as the positive electrode.
The CR2032 uses manganese dioxide for the positive electrode
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
