Purpose of Class
- This class teaches students what to look for when buying a SSD and explains why Solid State Drives are better then standard hard drives.
- SSD’s are built with NAND Flash Memory which is non volatile memory.
- There are numerous types of interface for Solid State Drive with PCIe being the fastest.
- TRIM is kind of like defragmenting for a SSD. Windows 7 and 8 do it automatically. XP and Vista require you use a manufacturer piece of software.
- “Memory Wear” means the NAND will degrade over time. Although this is technically a concern unless you are running a server for the likes of Facebook your PC/ Server will be replaced before the drive fails.
- IOPS means Input / Output Operations per Second and measures the total number of individual transactions per second the drive can handle. This is important in database operations.
- “Sequential Read/ Write Speed” means the speed the drive can read or write contiguous files.
- “Random Read /Write Speed” means how fast the drive can read/ write to numerous different files
