[vc_row][vc_column][vc_column_text]Every day there are lots of new technologies coming out to the market, now we are going to see different types of hdd and its performance.<\/p>\n

There are three different types of storage HDD in the market,<\/p>\n

    \n
  1. Hard Disk drive (HDD)<\/strong><\/li>\n
  2. Solid state drive (SSD)<\/strong><\/li>\n
  3. Non-Volatile Memory Express ( NVMe)<\/strong><\/li>\n<\/ol>\n

    [\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]1.\u00a0 Hard disk drive (HDD)\u00a0<\/strong><\/p>\n

    The hard disk drive is an electro-mechanical data storage device and its used\u00a0 magnetic force to write\/read the data on\u00a0 hdd rotating platters and performance based the RPM (Revolutions Per Minute<\/strong>) speed of the HDD. The HDD available\u00a0 with different speed\u00a0 as below,<\/p>\n

      \n
    1. HDD 4.8k RPM<\/strong><\/li>\n
    2. HDD 5.4k RPM<\/strong><\/li>\n
    3. HDD 7.2k RPM<\/strong><\/li>\n
    4. HDD 10k RPM<\/strong><\/li>\n
    5. HDD 15k RPM<\/strong><\/li>\n<\/ol>\n

      [\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text] \u00a02.\u00a0 Solid State Drive (SSD)<\/strong><\/p>\n

      The Solid state drive is a solid state storage device and its used integrated circuit assemblies to store data. SSD’s store data in semiconductor\u00a0 and based on NAND flush.<\/p>\n

      As of now there are 5 types of SSDs available\u00a0 ,<\/p>\n

      \u00a0 1. SLC(Single Level Cell) SSD<\/strong><\/p>\n

      \u00a0 2. MLC(Multi Level Cell) SSD<\/strong><\/p>\n

      \u00a0 3. TLC(Triple level Cell) SSD<\/strong><\/p>\n

      \u00a0 4. QLC(Quad Level Cell) SSD<\/strong><\/p>\n

      \u00a0 5. PLC(Penta Level Cell) SSD under development\u00a0<\/b><\/p>\n

      [\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]3. Non-Volatile Memory Express ( NVMe)\u00a0<\/strong><\/p>\n

      NVMe (Non-volatile memory express) is a new storage access and transport protocol for flash drives (NAND flash memory) and next-generation solid-state drives (SSDs).<\/p>\n

      Type of\u00a0 NVMe as below,<\/p>\n

      1. AIC NVMe<\/strong><\/p>\n

      2. U.3 NVMe<\/strong><\/p>\n

      3. U.2 NVMe<\/strong><\/p>\n

      4. M.2 NVMe<\/strong><\/p>\n

      5. NVMe-oF<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Here we are going to see what is the main difference between HDD vs SSD vs NVMe<\/p>\n
