Samsung SSD 850 Pro review

First class strong state drive at a top notch cost



The Good / The Samsung SSD 850 Pro has quick execution, high continuance – you can compose a great deal of information to it before it ends up inconsistent – and its 2TB limit is the most elevated available. The drive accompanies a ton of helpful highlights, including encryption, and an extraordinary execution boosting mode called Rapid.

The Bad / The drive is costly contrasted and contending strong state drives. The Samsung Magician programming just works with Windows.

The Bottom Line / The Samsung SSD 850 Pro is outstanding amongst other standard customer review strong state drives available, however there are less expensive choices with comparable execution.

Editors’ note: The survey was refreshed on July 6, 2015, when the new 2TB adaptation was discharged.

There are a lot of motivations to be amped up for the Samsung SSD 850 Pro.

It’s the primary SSD available that uses the creative 3D vertical NAND (V-NAND) streak memory for top execution and ultra-high continuance. It accompanies an once in a while observed 10-year guarantee and, among different highlights, has a Rapid mode that further lifts its execution. In addition, it’s one of the principal drives accessible in the all-new 2TB limit, alongside its kin the SSD 850 Evo.

Normally, however, the greater part of that includes some major disadvantages. Contingent upon the limits, the new Samsung drive is a standout amongst the most costly among standard SSDs, as of now costing $98, $152, $255, $489 and $1,000 for 128GB, 256GB, 512GB, 1TB and 2TB separately. (That is about £63 to £640 and AU$128 to AU$1,310 changed over.) Note that the estimating for the recently discharged 2TB rendition is the proposed retail cost, and its road cost will probably be lower.

If its all the same to you paying the premium, the Samsung conveys the best execution, most astounding limit and longest guarantee time as of now accessible available. It’s particularly awesome for the individuals who frequently need to compose a tremendous measure of information to the interior drive each day. Be that as it may, in case you’re on stricter spending plan, the 850 Evo is less expensive, with practically identical execution in numerous tests.


3D memory cell strings, ultra-high continuance

The Samsung SSD 850 Pro is a standard inner drive that backings the most recent SATA 3 (6Gbps) standard and will work in any occurrence where a customary SATA hard drive is utilized. Like most SSDs, it’s 7mm thick. Like most standard drives, it’s a square gadget that is 2.5 inches corner to corner, with the standard SATA port on one of its sides. The new drive looks precisely the same as the past 840 Pro model .

Within, nonetheless, the new drive is the main that conveys 3D vertical NAND streak memory to SSDs, called Samsung second-gen 86-gigabit 40nm MLC V-NAND.

Customarily, NAND streak memory cells – the capacity units on a SSD – are set level on the surface of the silicon wafer, restricting the quantity of cells you can pack into a square inch. On account of the Samsung drive, cells are likewise stacked up to 32 layers. This takes into account pressing altogether more memory cells in a similar measure of wafer bits, which enormously expands the thickness. That in addition to Samsung’s redone firmware and the enhanced MEX controller, enable the drive to likewise offer extraordinary execution and ultra-high perseverance.

Continuance is the quantity of program-delete (P/E) cycles a SSD has before you can’t compose onto it any more – read more about SSD perseverance here. Samsung says you can compose no less than 150TB (on the 128GB and 256GB limits) or 300TB (on the 512GB, 1TB and 2TB limits) of information to the 850 Pro before it comes up short on P/E cycles, twice that of the SanDisk Extreme Pro, which has a continuance of 80TB. This implies a large portion of us won’t go through the drive’s continuance in our lifetime.

Accommodating programming, enhanced Rapid mode

Similarly as with the 840 Pro and 840 Evo , the 850 Pro enables you to deal with the majority of its highlights through the Samsung Magician programming, which is right now accessible for Windows.

For instance, you can utilize the product to turn on or off encryption, over-provisioning – an element that utilizations part of a SSD’s storage room to upgrade the drive’s execution – and Rapid mode. Quick mode is special to Samsung SSDs and is the most fascinating and engaging component.

Quick is an acronym, remaining for Real-time Accelerated Processing of I/O Data. It essentially implies that it utilizes the accessible framework memory (RAM) on the host PC as an info/yield store to support the execution. Since most new PCs accompany a lot of RAM, Rapid is an appreciated component.

Beforehand with the 840 Pro and 840 Evo, Rapid utilized something like 1GB of RAM for reserve. Beginning with the 850 Pro, Rapid currently can utilize something like 4GB or 25 percent of the host PC’s RAM, whichever is bigger, as reserve. More store implies better execution. In my testing, I found no motivation behind why you shouldn’t utilize Rapid mode.

Premium valuing

Aside from the 2TB, which just turned out and has the proposed cost of $1,000, the US road costs of alternate limits are at $98, $152, $255, $489 for 128GB, 256GB, 512GB and 1TB individually. For the most part, the drive costs from 47 pennies to 59 pennies for each gigabyte, among the most costly available. The SSD 850 Evo for instance, costs just around 33 pennies for each gigabyte. Note that when purchasing SSDs, the higher the limit, the less cost per gigabyte. This implies purchasing bigger limit drives will give dependably you more for your cash.

It’s critical to take note of that while the SSD 850 Pro is quicker than the SSD 850 Evo generally, in true utilization, you probably won’t see by any means. The SSD 850 Pro’s 10-year guarantee, be that as it may, is unmistakably superior to the five-year of its kin.

SSD US road cost

NOTE: Measured in cost per gigabyte in light of current cost on MSRP utilized for the 2TB limit. The lower number demonstrates better esteem.

Top execution

The Samsung SSD 850 Pro did in testing. I tried the new drive with its 256GB, 512GB, 1TB and the new 2TB limits and they fundamentally offer a similar execution. The drives were tried as a fundamental stockpiling gadget that host the working framework, since the Rapid mode doesn’t work when the drive is utilized as an auxiliary drive. The test machine is a midrange PC running a Core i5 processor with 8GB of framework memory.

In our successive information exchanging test, the new drive scored a managed speed of 246MBps while doing both written work and perusing in the meantime, somewhat slower than the 251MBps of the SanDisk Extreme Pro. At the point when Rapid mode is turned on, be that as it may, the Samsung enlisted 287MBps, by a wide margin the quickest outcome.

CR Labs’ SSD information exchange execution

NOTE: Measured in megabytes every second.

Proceeding onward to the tests with the PC Mark benchmark suite, the new Samsung drive was reliably fantastic. The drive likewise scored the most noteworthy contrasted and different SSDs.

PC Mark 8 by and large stockpiling execution

NOTE: Higher number means better execution.

PC Mark likewise demonstrated that the Samsung SSD 850 Pro enhanced the application execution somewhat contrasted and the SanDisk Extreme Pro, particularly in Rapid mode.

PC Mark 8 stockpiling application execution

NOTE: Measured like a flash. Shorter bars implies better execution.

In all the Samsung 850 Pro is one of the quickest, if not the speediest SSD available. Note that you have to utilize it in a PC that backings SATA 3 (6Gbps) to have the capacity to completely value its execution.


In the event that cash isn’t an issue, you can’t turn out badly with the Samsung SSD 850 Pro. The drive has it everything: top execution, a lot of helpful highlights, the most noteworthy stockpiling limit (up to 2TB) and a super long 10-year guarantee.

Yet, cost is dependably an issue and in genuine utilization, odds are you won’t see the little additional execution the 850 Pro has over contending drives that are less expensive, for example, its kin SSD 850 Evo that costs somewhere in the range of 20 percent less and offers neck-and-neck execution in numerous tests.

For the most part SSDs are on the whole such a great amount of speedier than standard hard drives that the execution holes between them are insignificant to the client. So while the SSD 850 Pro is an awesome drive, deserving of the venture for proficient clients, it doesn’t offer the most for your cash.

By the day’s end, if the best arrangement is what you’re after, the 850 Evo is the best approach, however in the event that you need something first class with no bargains, the 850 Pro is the drive you need.
