SSD’s or otherwise called Solid State Drives are storage devices which have no mechanical components as compared to the traditional hard dives which have spinning electromagnetic disks and movable read/write heads. Here is a comparative study between the Samsung 840 EVO and ADATA XPG SX900 SSD’s.
The Samsung 840 EVO has storage capacity ranging from 120GB upto 1TB. Running on Samsung 3 core MEX controller and having a memory of Samsung 19nm toggle mode TLC, the peak read speeds for them as per lab tests are 46.3 MB/s and the peak write speeds are about 442 MB/s. Where as the ADATA XPG SX900 runs on LSI Sandforce controller and has a Intel micron 25nm MLC as for the memory and the peak read and write speeds as per lab tests are 23 MB/s and 248 MB/s much lower than the Samsung 840 EVO.
The Mean Time Between Failures (MTBF) on the Samsung is considerably longer at 1.5 m hours as compared to the ADATA at 1 m hours. The Samsung has a lower working temperature under load of just 36.3 degrees celsius as compared to ADATA having a working temperature of 70 degrees celsius, this means the former will save components that could deteriorate due to excessive heat. ADATA is thicker and heavier at 7mm and 68 gms whereas Samsung is thinner and lighter at 6.8mm and 58gms. Samsung trends higher in performance with greater sequential read speeds, more internal storage space, faster random read and write speeds and eventually lighter on the pocket.

Looking at the comparison above Samsung 840 EVO series is a clean winner in every aspect. It has got better looks, runs on a better controller and has more memory to price value as compared to the ADATA. It beats the ADATA substantially with a higher margin in terms of performance too, with higher read and write speeds, more running hours, lower working temperatures, higher random and sequential read and write speeds. In terms of visuals too the Samsung is thinner, shorter and lighter, and eventually even priced lesser as compared to the ADATA.
