SSD comparison: Sandisk PRo 960GB EXTREMEPRO vs. Samsung Pro Series 1TB

linuxuser · Nov 6, 2015

Looking for the "best" 1tb ssd for a Lenovo 440p laptop:

Looking at SANDISK CORP. 960GB EXTREMEPRO SSD SATA 2.5IN2.5 SDSSDXPS-960G-G25

vs.

SAMSUNG 850 Pro Series 2.5 1TB SATA III
Solid State Drive (SSD)
MZ-7KE1T0BW

Which is more resilient, has more endurance, lasts longer(longer MTBF), more reliable(no firmware headaches, software glitches, etc)?

I'm more concerned about reliability,MTBF, longer life, endurance, support, and the one that "just works flawlessly".

Less concerned about speed. All SSDs are going to be faster then my old laptop drive.

Appreciate your expert advice here.

Samsung. Hands down.

You will find that almost to the person here on Toms, we like Samsung SSD's. I have a 1TB Samsung 840 EVO in mine. Runs flawlessly, and I push it hard.

how about customer service...Seems Sandisk has chat and online customer service also. Samsung only has phone customer service for ssds.

One difference i would say about support is, based on previous experiance, Sandisk support is outsourced to India, i've always got indian accented ppl on the phone and their online chat would be the same.

Samsung only has phone support, and email support through here: samsungmemorysupport@sea.samsung.com and their phone support are americans. I've spoken to them several times and they are very helpful.

Sandisk Extreme Pro has greater consistency and lower latency in Write-intensive tasks. Its steady-state performance is enterprise class, and it uses proven MLC type NAND memory compared to TLC type NAND in the Samsung. Sandisk's MLC NAND has stood the test of time whereas Samsung's 3D TLC NAND is a more recent innovation. Sandisk Extreme Pro has a 10-year warranty . At home we have a Sandisk Extreme and a Sandisk Ultra both of which have been perfectly reliable for several years. My Samsung 840 EVO began losing data when it was about 14 months old. Did a firmware update and reinstalled Windows, and the Samsung has been OK since then. It's a good SSD, but even Samsung didn't know their TLC NAND would lose data when sitting unused for a while. It's the risk you take when going for innovation rather than tried-and-tested!

Except he's asking about the 850 Pro, which uses their MLC nand. Only the evo series use tlc.

You are correct that the 850 Pro uses MLC NAND. And yet, it's a "relaxed" 40nM die size which is new to the line and the implementation and controller are also revamped/new. Samsung has produced leading performance in several areas and it's an excellent design, but compare the steady-state performance and latency of the Samsung 850 Pro to that of the Sandisk Extreme Pro. When you throw a heavy Write-intensive workload at both of these high performance SSDs the Sandisk is able to sustain a continuous Write speed of ~210MB/sec. compared to around 160MB/sec. for the Samsung..

Equally crucial (no pun intended) is the total latency on heavy workloads. Again, look at the very superior low latency of the Sandisk compared to the Samsung.

If you're doing tasks such as video editing, video transcoding, rendering, large file transfer (like a Blu-ray movie file or a folder of several DVD movie files), game file copying, or other Write-intensive work then the Sandisk Extreme Pro is clearly a very good choice. When you take into consideration that it comes with a 10-year warranty and it sells for considerably less than the Samsung 850 Pro you must agree that it's a viable option for long term use.
