In other words, the electronic giant wanted to openly confess that as the user utilizes the SSD more, the performance-degrade disappears naturally. Samsung confirmed that this problem is confined only to data which has been re-written or changed and there are no problems with reduced read performance if the data was subsequently migrated from those cells or overwritten. Due to the error in the software algorithm, the 840 EVO performed read-entry processes aggressively, resulting in a drop in overall read performance. Generally, SSDs usually calibrate changes in status of cells over time via the flash management software algorithm. The company suggested that the performance slowdown is occurring on reading data which has been stored for long period of time (more than one month) and that has been written only once. Samsung said in a press statement that the read problem occurred on its 2.5 inches 840 EVO SSDs and 840 EVO mSATA Solid-State Drives because of an error in the flash management software algorithm. These model drives are experiencing read slowdowns, for which the company has released a firmware update and installation guide. Samsung 840 EVO series drives are the company’s second generation 3-bit Multi-Level-cell SSDs which are under scrutiny on this issue. Samsung, which is a world renowned electronics maker and a company offering affordable solid-state drives, is now in news for its SSDs which are facing read slowdowns with older data.
