Adding a 1TB SSD to my existing Samsung Galaxy Book 4 Pro has made it a whole new world! The SSD price has gone up a lot, but it solved my capacity concerns all at once. The speed from booting to running apps has really increased, so I’m very satisfied. I recommend this item to those who are considering upgrading their laptops! But be aware that it’s more expensive than the original market price.

Good~ Damn it, it’s great~ I can install a lot of games and it’s really nice haha. I bought it when it was on sale and it was totally worth it. It’s not super cheap, but compared to other options, it’s really a good deal.
The price has gone up even more now. Why is the price increasing like this…

It’s working well and I’m using it by mounting it on the back of an SFF case ITX board. The current price in Korea is about 600,000 won, but I bought it for about 250,000 won + 25,000 won shipping. I think it was a great purchase. Highly recommended.

After installing it, it was recognized well and was fast, which is great. I was worried it might be slow since it was an overseas purchase, but the speed is good too, so I’m happy.

The delivery was fine and the item arrived in safe condition.
I installed it on my newly built PC and it’s really nice.
I think I’ll buy it again if the 2TB product comes out at a special price.

I got it at a great price just when I needed it.
I was looking for an SSD to install in my mini PC, but the timing is frustrating.
There was no reason to hesitate at this price.
Thanks to you, all upgrade worries have been resolved.

The WD Black SN850X is an M.2 SSD based on PCIe 4.0, offering fast loading and transfer speeds with read speeds of up to 7,300MB/s and write speeds of 6,300~6,600MB/s. It features improved sequential performance compared to its predecessor and improved heat management, making it suitable for console (PS5) and PC gaming. However, there are also reviews stating that the improvement in 4K random performance is limited. Overall, it is a high-performance SSD with strong capabilities for gaming and large file operations.

This is my first time buying such an expensive item from Ali, and I am satisfied. The delivery was fast, and I purchased it at the lowest price in the world. In a situation where RAM and SSD prices are rapidly increasing, 2TB is a capacity that can last for 5 years. I hope that in 5 years, prices will stabilize and world peace will come.

It arrived much faster than I expected, which was great! Personally, I get very frustrated when deliveries are late, but I was really satisfied that I could order and receive it quickly. The product was also carefully packaged, so I received it cleanly without worrying about damage. Above all, the product quality is excellent. I think it’s great quality for the price. I was worried since it was an online purchase, but it exceeded my expectations. If I need any products in the future, I think I’ll buy them here again. The seller was friendly, the delivery was fast, the product was good, everything was perfect!

These days, memory prices have risen significantly, but I managed to purchase it at a relatively low price. It seems like they will continue to increase, so it might be a good idea to stock up in advance when buying. This model has DRAM installed, so its performance is also good.

It’s absolutely the best. The price is unavoidable, but there’s no need to mention the performance. Buy it twice. Buy it three times!!!

The read/write speed almost approached the bench mark specs, showing consistent performance. Especially if you often work with large files, you will notice a more significant performance improvement.

Comparison of hard drives purchased last year.
Both are 2TB, but are they 3rd generation?
The one I bought this time is the 4th generation, so I installed it on the computer right away without any worries.

For several years, I’ve had three of these 2TB products and bought one 1TB one. As long as there are no initial defects, they work perfectly fine and are plugged into computers and PlayStation. This product is quite famous, so I recommend it.

SSD performance is really good.
The boot speed has noticeably increased.
The game loading time has also been significantly reduced, eliminating frustration.
I am really satisfied with this level of performance at this price.
