Let’s actually replace the SSD and introduce how it changed before and after. This time, in addition to the standard for each volume, I also compared the data transfer speed of the external storage.
The free space has increased by more than 4 times, you can put the files that you use every day, and large OS updates can be done with peace of mind.
First of all, in terms of capacity, the free space before replacement is 205 GB. It’s really hard to store programs and data here. It will be necessary to devise ways to drop data into the cloud.
Free space after replacement has been significantly increased to 897 GB. This makes it possible to install many applications as long as they are not too large. For commercial use, it can be said that it is a capacity that does not cause much trouble even if a large amount of documents is stored on a computer.
Also, when upgrading to Windows 11 or applying a large update, free space in units of tens of GB may be required. If you want to use your computer for a long time, it is important to install a large capacity SSD and have enough free space.
Up to 2x reading speed and 3x writing speed
I checked the speed before and after conversion with CrystalDiskMark, but both reading and writing have improved significantly.
The Samsung 980 1TB SSD after the replacement is also connected to PCIe 3.0 x 4 lanes, and the “ZenBook 14 UM431DA” can be said to be able to extract the speed of an SSD with PCIe 3.0 x 4 lanes connectivity.
The speed is when it is actually used, which is not shown in the standard, and data acquisition is more convenient after replacement
Two important phenomena have been confirmed this time, so let me introduce them.
The first point is the specs on the laptop side. The information on the ZenBook 14 UM431DA product website says “USB3.1 (Type-C/Gen1)”, so it should hit 5Gbps, but in reality it’s transferring at 10Gbps. It seems possible. There is a possibility that the functionality was released after the release due to an update etc, but it was a happy miscalculation that I was able to transfer data equivalent to USB 3.2 Gen2.
The other is the behavior when actually transferring a large amount of data. When retrieving data from an external SSD with a maximum speed of about 1GB/s, the speed of the external SSD becomes a bottleneck, and there is often no difference in the data retrieval speed before and after the internal SSD is replaced.
In this case, the “SK hynix HFM256GDJTNG-8310A BA” before the replacement has a write speed of 800 GB / s in the standard, so even if it is replaced by a high-speed SSD, the data transfer speed of the external SSD is 200 MB / s. It can only be added to a point, and in theory, data transfer speeds will not increase significantly after the replacement.
However, current SSDs use internal caches to extract speed, so depending on capacity and console performance, there may be speed differences that cannot be seen in benchmarks.
Here is the case when 50GB of data was transferred from “Samsung Portable SSD T7 Shield (1TB model)” along with the main unit of computer, but “SK hynix HFM256GDJTNG-8310A BA” exceeded 600MB/s initially. It came out, it ended up being around 370MB/s, and it took 2 minutes 19 seconds for the transfer to complete.
With the Samsung SSD 980 (MZ-V8V1T0B / IT) after the replacement, although the speed was slightly reduced during the process, it was able to transfer at a rate of about 600 MB / s or more, and the time to complete a 50 GB file transfer was 1 minute 24 seconds, and it was a case where the benefits of replacing an SSD could be received even in the place of actual use.
