Both MLC and TLC are widely used consumer grade memory, with MLC being better in terms of endurance. Generally, SLC drives are traditionally the fastest, most reliable and most expensive drives available, usually used in the enterprise because of their considerably higher cost. performance and P/E cycles comparable to MLC.Not recommended for critical applications which require frequent updating of dataģD Vertical NAND - newer TLC NAND with different architecture, larger geometry and much higher endurance than TLC good fit for lower-end consumer products.somewhat slower read and write speed than MLC.TLC (Three Level Cell) - lower performance, lowest cost NAND Not suggested for critical applications which require frequent updates of data higher density (2 or more bits per cell).MLC (Multi Level Cell) - average performance, consumer grade NAND good fit for light enterprise use and high-end consumer products with more disk writes than MLC.lower endurance limit than SLC, higher than MLC.~ 20-30k P/E cycles per cell, great endurance good fit for industrial grade devices, embedded systems, critical applications.ĮMLC (Enterprise Multi Level Cell) - good performance, aimed at enterprise use.much higher cost (3+ times higher than MLC).lowest density (1 bit per cell, lower is better for endurance).~ 50-100k P/E (Program/Erase) cycles per cell, highest endurance SLC (Single Level Cell) - highest performance, at a very high cost, enterprise grade NAND There are different types of NAND flash chips in use today with different characteristics as follows: Each of these chips contain millions of cells with limited number of write cycles.
SSDs (Solid State Drives) use NAND flash chips. SLC, MLC or TLC NAND for Solid State Drives ?
