在我们深入之前，让我们来看看这款机型为我们带来了什么：
-
13.3英寸LED背光IPS视网膜级显示屏，分辨率2560 × 1600（227 dpi）支持P3色域
-
1.4 GHz四核心Intel Core i5处理器（可睿频加速至3.9 GHz）内建Intel Iris Plus 645 GPU
-
板载8 GB 2133 MHz LPDDR3内存
-
128 GB、256 GB、512 GB、1 TB或是2 TB PCIe SSD存储
-
双雷雳3（USB-C）端口，支持充电、显示输出、雷电接口以及USB3.1 Gen2
-
Apple T2定制协处理器
-
-
-
为了在Touch Bar旁边为Touch ID腾出空间，苹果似乎削短了左侧热管的长度（下侧）。参见2016款“功能键”版本（上侧）。
-
我们需要为此担心吗？散热能力似乎在这些超薄的“Pro”系列笔记本中已经被无视了。新处理器的15W TDP并不比2016款小。
-
在我们的Manta螺丝刀套件的帮助下，我们卸下螺丝，将电池排线卸下以断开电源。
-
在曾经2016款上存活的模块化SSD的位置上，我们剥离了遮盖的贴纸，并看到了一个被焊死的屏蔽罩。这也许不惊讶，但实在让人失望。MacBook Pro产品线上剩下的唯一能升级的组件消失了。

I love how professional these breakdowns have become over the years!
SSD chips do go bad over time; most vendors recommend total replacement after 240 gigabytes of overwrites per gigabyte of chip. Soldering down the SSD flash chips means these machines need Ball Grid Array rework when reconditioned for resale after lease return. Apple will be doing that rework, so we can maybe assume the ticklish microsurgery doesn't phase them?
Why solder them down in the first place? Because of the T2 chip. T2 is very…possessive of SSD memory.
But apple is not gonna do the repair beyond the warranty, so I don't believe it's a consolation that apple would do that repair when I buy computers to last me a decade. You seem even a bit optimistic about this.

I’m very curious about SSD failures over time. Are there are any stats out there? I’m talking about the high quality NAND used in the likes of Apple SSDs and not USB/SD-card failures.

Ya no. Nearly every consumer grade SSD comes with a 5 year warranty (or ~150 TBW per 250 GB). An SSD will last for decades without issue or loss of space. Modern SSDs eclipse traditional HDDs and even those these days can last a good chunk of time (my NAS is purring and it’s HDDs are about 6 years old).
When you say “most vendors” I’m sure you meant to say no one. People have long been crunching theoretical usage patterns in most general consumer usage against SSDs and have figured they’ll last something like 15 years, give or take. Obviously it depends on your usage pattern, but if you wrote 20 GB per day, every day for the life of drive, you’ll hit the manufacturers estimates in ~ 20 years (150 TBW per 250 GB). And that’s the bottom end. So at the bare minimum, with even aggressive usage (45GB a day), you’re likely going to see 10 years, easy. That’s if the drive dies right at 150 TBW/250GB, which is pretty %#*@ unlikely.
