The downside is that as each cell holds more data, it leads to reduced drive endurance, reducing the number of P/E cycles an SSD is rated for. SLC and MLC NANDįaced with these issues, engineers have come up with a clever way to get more data storage capacity from the same amount of NAND flash in an SSD - by increasing the bits of data each cell can hold. There is currently no way to totally avoid this problem with any kind of flash memory. Rated in P/E (Program-Erase) cycles, each cell in an SSD can only be written to a certain number of times before it no longer holds an electrical charge. The second issue is that flash memory has a limited lifespan. Although SSD prices have come down an astonishing amount over the last decade, in part thanks to increased manufacturing efficiency with lower overheads and explosive growth in demand, there is still an ongoing need to reduce the cost per gigabyte of flash storage. The first limitation is that flash storage remains generally more expensive than hard disks of the same capacity. Take your files with you with the best portable SSD.Looking for something cheaper?
