Steam deck EMMC spec?

[sasquatc4]

So the specs of all the nvme versions are listed but which revision of emmc is not. Is there any way to know this before preordering? There are orders of magnitude differences in speed between versions with the latest version being almost equivalent to a standard sata ssd and the much older versions that most people are familiar with being very very slow

It would be a huge determining factor if the emmc is dog slow in comparison and uses an older version

64 GB eMMC (PCIe Gen 2 x1) -- 500MB/s max
256 GB NVMe SSD (PCIe Gen 3 x4) -- 4.000MB/s max
512 GB high-speed NVMe SSD (PCIe Gen 3 x4) -- 4.000MB/s max

For reference;
SATA 3.0 -- 750MB/s (Theoretical max) ~550MB/s (Actual max)

The specs just mention the interface to which they are connected. I added the theoretical max speeds, but if they will actually achieve anywhere close to those we do not know.

eMMC is basically just an SD card soldered to a motherboard. It will not be terribly fast.

which is why I ask if there is anyway to know which emmc spec they have actually gone with since emmc 4 is a far cry from emmc 5 which can actually do 500 MB/s and most previous devices that use emmc have all cheaped out and gone with some early 4 spec with the diff between even 4.5 and 5.1 being a 3x speed increase across the board

emmc 5 speed IMHO, completely tolerable for most games (barring large map loads on MP type games which you probably wont even be doing on here) I mean thats sata SSD speed for the most part. Emmc 4.x on the other hand could be very painful. SD cards are much much lower than emmc 5.1 sitting at around 90 MB/s (assuming only UHS-I support, if UHS-III is supported then it goes up dramatically), so its a huge difference from being 'just an sd card soldered on'

It doesn't even matter. If its based on an SSD and not MicroSD/typical USB Flash, it will be fast enough that waiting won't be much of a thing as long as you have good connection.

I myself was hoping that the "internal" storage could be swapped out, as opposed to supplemented by an insertable SD card, but am grateful there's at least an option to use them.

I am wondering if the integrated storage is socketed or soldered; I recognize that 3rd party replacement of the integrated hardware may come with risks (thermal, driver, physical contraints for the storage module to physically fit etc) but it's not enough for me to consider it to be a show stopper for me.

Is it listed somewhere what speed "ethernet" is supposed to be? They make no reference on the "Tech Specs" page to describe that speed expectation. 10mb is what Ethernet means officially; 100mb is "Fast Ethernet" and the speeds beyond that have their own official terms as well.

There have been many consumer devices that have network interfaces that may light up at a gigabit or 100 megabit, only to discover that well no that is what it electrically signals at, but due to sharing the pci or pcie bus with other stuff, it really is 150 megabits but requires a gigabit port to do it.

I am going to guess not too many users really care much about that as long as it connects, but I'd keep that in mind when it comes to content/library management. It may be much faster to just load an SD card (or cards--for portability) with the games prior to going on a trip with no constant connectivity to leverage to easily install something outside of the home.

But really I think the decisions made for the design are not problematic and I'm just wishing for more clarity about the restrictions shaping the decisions.

Plenty of people are.. not so savvy as to understand the technical differences for some of this (just reading how people blame developers for problems the users cause for themselves), but the options Valve is providing will likely go quite a ways to cut down on the performance variability that otherwise is to be expected on a more traditional desktop or laptop with a wide variety of hardware options.

Seeing how tight it is, it's probably soldered.

I do hope no tho, and hope the battery is easily replacable for DIY when you are out of warranty.
