Most of the friends and collegues starts asking me the question about the difference between SSD and Flash Drive. I thought of writing this blog..so here it is
‘Flash Drives’ are a generic term which used for anything from USB memory sticks to SSDs. An USB flash drive uses lower quality low performance NAND flash with just 1 or 2 channels. Its durable, cheap but slow. An SSD on the other hand uses high performance NAND with mutliple channels. ( 12 or 8 is not uncommon), and there is a memory controller on a SSD which is much better and both can store data even if its not powered.
Flash drives (USB) are slow storage devices where as SSDs are high performance drives. They’re much faster than normal HDDs.
A USB flash drive uses USB, which is generally a slower interface than the Serial ATA interface. A USB flash drive is generally thought of as a removable device by the OS and is managed as such. A SSD is treated similarly to a hard drive, and is often recognized by your OS as a type of fixed disk.
USB flash drives and solid-state drives are both based on flash memory. Most of the flash memory use NAND memory, which are available as single-level cells (SLC) and multi-level cells (MLC). Single-level cells store a single bit in a single memory cell, whereas multi-level cells store more than a single bit in a single memory cell. The MLC accomplishes this by allowing each memory cell to store multiple electrical states, therefore, allow one MLC cell to store more information than one SLC cell. For example, a MLC that uses 4-levels can store 2 bits of information. MLC are cheaper, as they can store more information per memory cell than SLC. Cheap, large SSDs and USB flash memory use MLC disks, although not necessarily. MLCs sounds great in terms of storage density, but it does have a catch. MLCs are slower than SLC. Therefore, the large capacity USB flash drives and SSDs tend to be slower. Solid-State Drives (SSDs) have no moving parts, high reliability and longer life-span than traditional hard drives
One of the example of SSD is Intel X25-E Extreme SATA Solid State Drive
