Both the 840 Pro and the 840 use the MDX memory control of Samsung. The newest processor features three ARM Cortex-R4 centers compared to the 830 family’s ARM9 processors, as well as the centers run at a higher clock speed (300MHz compared to 220MHz). The performance figures for AS-SSD and SiSoft Sandra represent the operation in a specific type of information workload of a drive. Serial read/write tests quantify the abilities of an SSD writing or when reading a big block of contiguous information. One big picture or ISO image will examine a drive’s serial operation (assuming the target drive is not badly fragmented). In AS-SSD, the; Samsung 840 Pro hit successive read/write speeds of 481 and 518 MBps. That is neck and neck using the OCZ Vector Set VTR1 25SAT3 256G (509.42 and 495.72 MBps, respectively).

The 4K read/write evaluations assess the efficiency of HDD or an SSD when reading and writing little chunks of information. These little read/writes are essential to the regular operation of a storage alternative. The “64 Threads” evaluation in AS-SSD means the standard software spins off 64 different 4K read/write jobs. This stretches the control’s capability to handle workloads that are such, but in addition provides a performance metric that is more realistic –an operating system is always reading and writing information to applications and multiple services concurrently. Again, the more inexpensive Samsung 840 is nearer on read operation (329MBPs) than on writes (187MBps).
