Question 1

Is the SSD 4T|SAMSUNG MZ-V9S4T0B/AM R suitable for gaming storage?

Accepted Answer

Yes, the Samsung 990 EVO Plus SSD with 4TB capacity is suitable for gaming storage due to its high performance, including sequential read speeds up to 7,250 MB/s and write speeds up to 6,300 MB/s.

Question 2

How is the performance of the SSD 4T|SAMSUNG MZ-V9S4T0B/AM R?

Accepted Answer

I installed it as C drive in my ASUS G16 Laptop with an H285 CPU 
After 3 month I get a sequential Read speed of 6,979 MB/s and a sequential write speed of 4,231 MB/s 
At the same time I installed the SAMSUNG SSD 990 PRO 4TB as my D drive, which I am using on a daily basis for video editing. 
On this one I get a sequential Read speed of 7,004 MB/s and a sequential write speed of 5,107 MB/s

Question 3

How easy is it to install the SSD 4T|SAMSUNG MZ-V9S4T0B/AM R?

Accepted Answer

Very Easy. If you are building a desktop with a motherboard. I would recommend installing it before you put it into the case. Remember that the golden leads go into the slot on your motherboard PCIE slot. Sometimes it goes in at an angle and then you push it down gently. Others you have to insert the golden leads into the motherboard slot with a slight amount of pressure. These components are made to fit exactly. So if it gets stuck, STOP, dont force it and look at the direction or flip it over. The side with the sticker or chips face you (upwards). Finally depending on the motherboard, the semi-circular notch at the other end either needs a screw to hold it in place or the motherboard will have a sliding notch (opposite shape_ to help keep it in place.  You DO NOT need to remove the sticker and if your motherboard comes with heatsinks at the bottom, peel off the tape before you insert the motherboard. Just a side note that this 4TB M2 drive has been performing very well for the past month and I have not had any issues yet. The read/write speeds appear quite fast (though I have not measured it using tools). All in all a great M2 solution for the price as of this writing in 2025

Question 4

Should I choose the 990 EVO Plus or the 990 Pro?

Accepted Answer

The 990 EVO Plus offers 4TB capacity, HMB instead of onboard DRAM, and PCIe 4.0 x4 or 5.0 x2 operation. Reddit comparisons raise DRAM and sustained-workload performance as trade-offs; the better choice depends on workload, slot configuration, and current price. The supplied information does not establish that one is universally better.

Question 5

Is the 990 EVO Plus suitable for frequent, very large file writes?

Accepted Answer

It is rated for sequential writes up to 6,300 MB/s, but that figure is not a guarantee of sustained speed during long transfers. Reddit discussions specifically raise sustained-write performance and the lack of onboard DRAM as considerations for intensive workloads. Compare workload-specific testing if long, repeated writes are central to your use.

Question 6

Will the 990 EVO Plus work in a PCIe 4.0 or PCIe 5.0 M.2 slot?

Accepted Answer

It supports PCIe 4.0 x4 and PCIe 5.0 x2, according to the product information. Check your motherboard or laptop manual for M.2 NVMe support, available lane configuration, and physical clearance before buying; the connector being M.2 2280 alone does not confirm compatibility.

Question 7

Is the 990 EVO Plus a good choice for everyday use and gaming despite having no DRAM?

Accepted Answer

It may suit everyday computing and gaming: it has no onboard DRAM but uses HMB, and its rated sequential speeds are up to 7,250/6,300 MB/s. Reddit discussions identify heavy, sustained writes as a more relevant trade-off than ordinary use. Actual performance depends on the workload and system.

Question 8

Does it come with a heatsink?

Accepted Answer

The listed product is an M.2 2280 SSD, and the product information does not list an included heatsink. Check whether your computer has an M.2 cover or cooling solution, and confirm that any added heatsink will fit in the available space.

Question 9

Will I get the advertised speeds in my computer?

Accepted Answer

The drive is rated for sequential reads up to 7,250 MB/s and writes up to 6,300 MB/s. Actual speeds depend on the computer’s PCIe interface and other system limits; an older or lower-bandwidth slot may run the drive below its maximum rating.

Question 10

Who is this 4TB SSD suitable for?

Accepted Answer

It suits PC or laptop users who need 4TB of internal NVMe storage for large libraries or files and whose system supports an M.2 2280 PCIe drive. Its listed sequential speeds are up to 7,250 MB/s read and 6,300 MB/s write, but realized performance depends on the host system.
