Samsung SSD 850 EVO Conclusion

IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.

Our first rating is performance, which compares how effective the Samsung SSD 850 EVO performs in benchmark operations against competing SATA-based solid state drive storage solutions. For reference, Samsung specifications suggest 540 MB/s maximum reads and 520 MB/s write speeds from all SSD 850 EVO model capacities. In our storage benchmark tests this solid state drive performed beyond this speed, producing results that surpassed the fastest SATA-based products previously tested. ATTO Disk Benchmark tests proved the 500GB Samsung SSD 850 EVO was good for delivering 552/532 MBps peak read/writes speeds, placing among the fastest performance we’ve recorded from any SATA-based drive. Linear testing with AIDA64 Disk Benchmark produced 516/483 MBps, finishing at the very top of all results just above the 850 PRO. Sequential read/write speed tests with AS-SSD Benchmark produced 586/330 MBps, this time trailing the 850 PRO which topped our charts.

The Samsung SSD 850 EVO solid state drive sent to us for testing is advertised to deliver up to 98,000 random 4KB read IOPS at QD32, and 90,000 random 4KB write IOPS from its 3-core MEX controller. Using Iometer operational performance tests configured to a queue depth of 32 outstanding I/O’s per target across 100% of the drive, our benchmarks produced 86,192 combined IOPS performance from the 500GB drive. This places performance nearly 8800 IOPS behind the 850 PRO, which produced 94,985 from the 256GB sample. Looking at 4K 32QD test results using AS-SSD and CrystalDiskMark, the 500GB Samsung SSD 850 EVO established itself as a truly dominant product by typically surpassing performance on all other SATA-based drives tested. PCMark test results illustrate this point.

Performance for the Samsung SSD 850 EVO can be easily summarized using one word: Superior to all other, with exception to the Samsung SSD 850 PRO series. Even then, the race is too close to call in some tests.

Solid State Drives are low-visibility products: you see them just long enough to install and then they’re forgotten. Like their Hard Disk Drive counterparts, Solid State Drives are meant to place function before fashion. Anything above and beyond a simple metal shell is already more than what’s expected in terms of the appearance. Samsung has created a sleek 7mm profile with an elegant deep black finish on the Samsung SSD 850 EVO series. As solid state storage controllers become faster and more advanced, heat dissipation through the enclosure walls may demand that chassis designs become more beneficial than they previously needed to be. For now, the adaptive thermal monitoring system on the 850 EVO suits it well for managing heat in ultrathin and embedded designs.

Construction is probably the strongest feature credited to the entire solid state product segment, and Samsung emphasizes this quality. Solid State Drives are by nature immune to most abuses, but add a hard metal shell and the chance for failure is reduced to internal component defects. If there are ever any problems with any Samsung SSD 850 EVO during the industry leading 5-year warranty period, end-users may visit Samsung Support or create a Service Request.

As of 08 December 2014, the Samsung SSD 850 EVO series launches in the following capacities and retail prices:

Description Capacity Model MSRP
Samsung SSD 850 EVO Series 120GB MZ-75E128BW $89.99 (Amazon | B&HNewegg)
240GB MZ-75E256BW $139.99 (Amazon | B&HNewegg)
500GB MZ-75E500BW $249.99 (Amazon | B&H | Newegg)
1TB MZ-75E1T0BW $469.99 (Amazon | B&HNewegg)

In conclusion, the differences between Samsung’s SSD 850 EVO series and their 850 PRO counterparts are difficult to see. 850 EVO has identical write speeds to 850 PRO, but write speed is a negligible 10 MB/s slower. IOPS performance is virtually identical on paper, but there’s a notable difference favoring 850 PRO in the benchmark results. Both offer a five-year warranty, and identical total bytes written (TBW). The prices are nothing alike, however, and clearly favor the Samsung SSD 850 EVO as capacities increase. Based on these factors, performance enthusiasts are well-suited to 850 EVO while VM administrators would be better off with 850 PRO.

The Samsung SSD 850 EVO may not offer the industry’s least expensive price per gigabyte among solid-state storage devices, but 850 EVO also avoids being the most expensive. Considering that no other SSDs can deliver sustained transfer speeds or operational performance to the same level at the same cost, it’s nice to see prices are reasonable. Benchmark Reviews recognizes how well the Samsung SSD 850 EVO series delivers highest-end operational performance to power users by topping our IOPS and transfer speed test results, proudly earning our Golden Tachometer Award.
