Samsung SSD 850 EVO mSATA 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 mSATA drive 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 mSATA 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 250GB Samsung SSD 850 EVO mSATA was good for delivering 552/530 MBps peak read/writes speeds, placing among the fastest performance we’ve recorded from any SATA-based drive.

The Samsung SSD 850 EVO mSATA solid state drive sent to us for testing is advertised to deliver up to 95,000 random 4KB read IOPS at QD32, and 88,000 random 4KB write IOPS from its 3-core MGX 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 64410 combined IOPS performance from the 250GB drive. Looking at 4K 32QD test results using AS-SSD and CrystalDiskMark, the 250GB Samsung SSD 850 EVO mSATA drive established itself as a truly dominant product by typically surpassing performance of most other SATA-based drives tested. PCMark test results helped to further illustrate this point.

Performance for the Samsung SSD 850 EVO mSATA drive can be easily summarized using one word: Superior. These SSDs are faster and more capable that nearly all others, with exception to the Samsung SSD 850 PRO series. Even then, the race is close.

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. As solid state storage controllers become faster and more advanced, heat dissipation may require a heatsink. For now, an adaptive thermal monitoring system on the 850 EVO series 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, but 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 April 2015, the Samsung SSD 850 EVO mSATA and M.2 series are available following capacities:

Description Type Capacity Model MSRP
SSD 850 EVO mSATA 120GB MZ-M5E120BW $79.99 (Amazon | B&HNewegg)
250GB MZ-M5E250BW 129.99 (Amazon | B&H | Newegg)
500GB MZ-M5E500BW $229.99 (Amazon | B&H | Newegg)
1TB MZ-M5E1T0BW $429.99 (Amazon | B&HNewegg)
M.2 120GB MZ-N5E120BW $79.99 (Amazon | B&HNewegg)
250GB MZ-N5E250BW $129.99 (Amazon | B&HNewegg)
500GB MZ-N5E500BW $229.99 (Amazon | B&H | Newegg)

 

Description Capacity Model MSRP
SSD 850 EVO SATA Series 120GB MZ-75E128BW $79.99 (Amazon | B&HNewegg)
240GB MZ-75E256BW $119.99 (Amazon | B&HNewegg)
500GB MZ-75E500BW $209.99 (Amazon | B&H | Newegg)
1TB MZ-75E1T0BW $389.99 (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 close, but there’s a notable advantage favoring 850 PRO in our 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 series 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 series 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 Recommended Seal of Approval.

    I would have liked to have seen a seperate IOP’s test that shows the read and write iops and if they were anywhere near the stated values for the SSD , combined values of 50/50 is not a normal scenario for everyday use it would be more like 80R/20W …..

    Other than that very nice review Olin thank you
