Samsung 850 EVO SSD Review (4TB) – Bigger than Ever!!!

REAL WORLD FILE TRANSFER

We also wanted to see how performance was in a real world use when transferring large files to the SSD. For this test we are going to simply stress write performance by transferring over a 30GB folder of movies off of a 512GB Samsung 950 Pro to the test SSDs and time how long it takes. Once complete we can calculate the average speed. For reference we have included both a 2.5″ and 3.5″ WD Blue HDD.

In this test the Samsung 850 EVO 4TB capacity shows no weakness. During large file transfers its write performance is up there with the best of them. It averaged 549MB/s, ranking this 4TB model above its smaller capacities.

POWER CONSUMPTION

For our power consumption testing, we have the drive connected to the system as a secondary drive. To record the wattage, we are now utilizing a Quarch Technology Programmable Power Module. It allows us to accurately measure power consumption over time and is flexible enough to allow us to test any SSD that comes our way.

Quarch Technology Power Module Angle

Our power analysis may change as time goes on, but for now we are looking at just a few metrics with the main goal of measuring our results against the manufacturer’s ratings. Because most consumer systems are at idle for about 80% of the time, idle power consumption is an important measure to look at when understanding the efficiency of a drive.

4TB Samsung 850 EVO Idle

In this comparison we can see that the 4TB Samsung 850 EVO does indeed have an Achilles heel. At idle power consumption is much greater than that of the many other SSDs we have tested. At 1.7W watts, this SSD guzzles power like an old 8.4L V8.

POWER EFFICIENCY

Finally, we wanted to post up a graph of the power efficiency of the SSDs in comparison. We are looking at MB/s per Watt in this graph. The higher the result, the better.

4TB Samsung 850 EVO efficiency

Lastly, we can see that in this comparison, the 850 EVO gains back some brownie points by being more efficient than many other comparison drives, including its smaller 500GB variant. Still, however, if you are to use this SSD, it may be a better choice for you to throw it in a desktop rather than a laptop.

Samsung controller S4LP052X01-8030 is also known as “MHX”. Please edit article, add “MHX” to text, for search optimisation.

Hoping for some increased capacity Samsung ssd’s in the msata format. I’m sure that even now a ton of people still need AND use that type of ssd.

No way I am paying 1499.00 for something that will be 850.00 in 6 months
