We already called the SSD-evolution a race to the bottom: the prices keep going down, meaning larger capacity SSDs become more accessible. Every manufacturer keeps a close eye on the other manufacturers. Seeing as how Crucial and OCZ are offering SSDs below the “850 Evo-price levels,” Samsung is introducing the Samsung 750 Evo to compete.
The Samsung 750 Evo-line is based on the same S4LN062X01-controller as the 850 Evo, called the Samsung MGX in marketing terms. The difference between the two is the used TLC-flash memory: where the 850 Evo uses 3D NAND, the manufacturer uses regular ‘2D’ memory for the 750 Evo. This is produced using the smaller 16nm-procedure, potentially having a negative impact on the life span. On the other hand: all of the competitors use similar memory at this price point. A second difference is the cache. With 256 MB it is half the size of the 850 Evo.
Other aspects of the featureset show a lot of similarities when compared to the 850 Evo. The 750 Evo has the same extensive encryption-possibilities, where 256-bit AES-encryption is applied. The Samsung Magician-software is also present, used for easy data migration and the RAPID-mode (DRAM-caching), among other things. Furthermore part of the memory is reserved to act as a fast write buffer, something that Samsung calls TurboWrite.
Samsung promises sequential read/write speeds of up to 540 and 520 MB/s respectively, where the write speed can only be gained when using TurboWrite. The random-performance should be 97,000 IOPS for read and 88,000 IOPS when writing. Even the power consumption is mentioned: 2.8 watt under heavy load, 50 milliwatt in idle and 6(!) milliwatt in DevSlp-mode. The TBW-values are always nearly 300 write-cycles, namely 35 TB for the 120GB-variant and 70 TB for the 250GB-variant.
The 750 Evo 120 GB costs 72 dollars on average, 60 cents per GB. This is quite expensive anno 2016. The 250GB-variant has an average price of 97 dollars, this means results in about 39 cents per GB- a lot better. The 750 Evo variants also come with a three year warranty, two years less when compared to the 850 Evo.
