I just bought a 1TB NVMe PCIe SSD for $110.00 off Amazon. It's about 1Gbit/sec slower than the next price point but it's about 2 or 3 times as fast as my existing SATA SSD. The next-highest price point was a 3Gbit/sec 1TB SSD for about $150.00.

It’s 3GigaBYTES/s, not Gigabits/s. Nvme drives really are massively faster than their SATA counterparts.

Oh shit. Well then that's cool.

It's worth remembering that the storage architecture of T2-based Macs (like this MacBook Air) is very different from previous Macs and any PCs. The T2 chip is an Apple ARM SoC running Darwin/XNU (basically a cut-down iOS). It connects to the Intel system using a variety of buses. From a storage perspective, the T2 is the storage controller. It sits between raw NAND flash and the Intel system (connecting to the Intel…

It might just be newer, higher density NAND. It's cheaper, but slower and less reliable.

I think the most common pain point with this is going to be an initial iCloud sync if your drive is full of stuff.

Thats giga bytes per second. You’d need a 10Gbps+ internet connection to even start getting close to saturation.

The MBA has Thunderbolt 3 ports good for "up to 40 Gb/s", so all you need is an external box to convert that to 10gig ethernet. Sonnet sells one: it weighs 3 lbs, has a 60W power adapter, and costs $500. It's the perfect accessory for your 2.75lb, 30W, $999 laptop!

I wonder if there’s improved life expectancy of slower SSDs? (Serious question, not Apple fanboying here, any change in life expectancy is presumably incidental to reduction in price point)

No, it's the opposite. They're packing more bits into each NAND cell, which causes both the IO to be slower, and the drive less reliable.

1.3 GB/s vs 2 GB/s read. I think it's perfectly reasonable given most users aren't going to be doing high I/O, and if they did, they'd just get a MBP.

1.3GBps is still super fast.

It wasn't that long ago that we were using 7200rpm HDs which capped at around 110MB/s for large files.

I don't think that's a fair characterization - I won't be getting a MBP regardless of the amount of I/O I do, because I very much dislike the Touch Bar.

What do you dislike about it?

I haven't really noticed mine.

Yep. I just picked one up a couple weeks ago, it's my first non-MBP but seeing as I have a company-provided i7 MBP I didn't feel like I needed another powerhouse machine for side projects and occasional coding for fun. I love that I have no touch bar but I do have Touch ID. Coming from a 2014 MBP 13 I definitely didn't notice the slower SSD speed -- editing raw camera files in Lightroom is really fast and the display…

The biggest bummer of these machines is apples lack of vp9 hardware decoding in macos, it makes 4k youtube unwatchable. For high motion content (mountain biking videos) 4k is the only way to watch even on a tiny laptop screen due to youtube’s horrific compression. Its an absurd limitation considering the hardware has full support for it! I know it sounds insane but I returned mine for a quad core 13” mbp just to brut…

Do hardware decoders for vp9 even exist?

Apple might have chosen cheeper SSDs to lower prices - which in principle think is a good idea on the entry level laptop, even cheap SSDs are plenty fast - why are they still charging insane prices for their SSD upgrades? Current market prices for SSD are between 150 and 300€/tb. For SSD upgrades in the MB Air, Apple is charging 240€ for each upgrade step. That means prices between 1920€/tb (128->256g) and 480€/tb (5…

Apple's prices used to be non-insane. Marked up, yes, but not nuts. Wasn't even that long ago. You'd have people post stuff about "look I can get a PC that's just as good for 40% as much, what a ripoff!" but it'd always turn out they were choosing worse parts. These days, though, between price hikes, mediocre to poor base memory amounts and disc sizes, and massive markup on upgrades, it's not true anymore. Their pric…

The $1K aluminum monitor stand is symbolic in that regard, even though it's not even hardware.

There's accelerated decoding on at least some of the modern mobile platforms, and from all the major graphics providers on laptop/desktop.
