Samsung 850 EVO 500GB SATA 2.5-inch SSD

Drive That Blends Performance and Reliability

Samsung 850 EVO 2.5-inch

The Bottom Line

For anyone thinking of adding an SSD to their personal computer that happens to use the SATA drive interface, the Samsung 850 EVO series offers some of the best performance outside of professional class drives. They may cost a little bit more than other consumer drives but the performance and warranty and worth the price.

Review - Samsung 850 EVO 500GB 2.5-inch SATA Solid State Drive

Samsung is one of the biggest names when it comes to solid state storage. While most other companies have to buy components such a controllers and NAND memory chips from various suppliers, Samsung produces it all themselves. This gives them a distinct advantage in a number of ways and makes them stand out amongst a sea of available drives. The 850 EVO is their latest generation of consumer SATA based SSDs. They use the 3D V-NAND technology that gives them a higher data density than many other drives and also provides them with a slight advantage in performance.

For this 2.5-inch drive, it manifests itself in an extremely thin 7mm profile that allows this to slide into a wide range of laptops that might happen to have thin profiles. It also means it is easier to stack a number of them within a desktop system.

I'm looking today at the 500GB version of the drive.

The reason that I chose this is that the price is not unreasonable like many of the terabyte and larger versions but it still provides a good amount of storage space making it functional as a stand alone drive. Sure, it is possible to get the 250GB version for half the price and some people can survive on that small of a drive but this version still offers a better overall capacity level. Now the drive still runs on the SATA interface which makes this an attractive option for anyone that is looking to upgrade an older desktop or laptop computer from a traditional hard drive to an SSD to give their system a much-needed performance boost. This does mean that compared to something like the Samsung 950 Pro M.2 drive is going to be extremely lacking but most people don't have systems that can use that and it costs over twice as much as this drive for roughly the same capacity.

So how well does this perform in real world usage? In terms of the sequential tests which the companies like to advertise, I was able to get 521.7 MB/s for reads and 505.1 MB/s for writes. While lower than what Samsung advertises, it is still quite good and better than many other consumer SATA drives. Sure, Samsung offers its 850 Pro which will provide better performance especially when dealing with more IO intensive applications, but it also costs a good deal more for the same level of capacity.

For those looking for security for their data, the 850 EVO does support both the AES 256 and Opal 2.0 encryption methods. This helps keep your data secure while not impacting performance dramatically. This is a key feature for many business users that are concerned about security with their laptop computers. It is also a feature set that is missing from many low-cost SSD options.

One of the best parts about Samsung's drives is their reliability and warranty. They have some of the best overall reliability rates when it comes to failures in SSDs which are already quite uncommon. To back this up, they provide a five-year warranty with the drive.

It should be noted that this is actually a fairly complicated warranty because they also rate it at 150TB of writes to the drive. Frankly, this is longer than five years based upon consumer usage but it is there mainly to determine the drives from being used in enterprise systems instead of a more expensive class of drives.​

Pricing for the drive was initially $270 when it was first released but the MSRP from Samsung is nor $179. Street pricing of the drive will often find it below $150. This puts it at a $.30/GB which is above average for consumer class drives in this capacity range but Samsung comes with higher performance and better warranty which is something to keep in mind.
