Many people know that SSDs are much faster than the traditional electro mechanical disk drives, use less power, produce less heat and last much longer. The only drawback is that they cost a little more - not so much now though; so they are a sensible upgrade for both laptops and towers if most cases. To get the best performance out of SSDs Windows should be installed from scratch. If cloning or migratingfrom an old disk there are a few things that can be modified to improve performance or longevity.
REGEDITand navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParametersLook for the keys and . Both should be set to 0.
TRIMcommand to have the disk handle delete operations in the background. First check whether this is already set by getting to the
CMDprompt and typing if you are informed that it is set to 0 move on to the next thing otherwise enter the following command to enable TRIM
There are currently two types of memory used in SSDs: SLC (single-layer-cell), and MLC (multiple-layer cell). SLC lasts much longer but costs more to make. All the cheaper drives and most USB flash memory drives are MLC based devices. Flash memory can only be programmed and erased a limited number of times. This is often referred to as the maximum number of program/erase cycles (P/E cycles) it can sustain over the life of the flash memory. Single-level cell (SLC) flash, designed for higher performance and longer endurance, can typically operate between 50,000 and 100,000 cycles. As of 2011, multi-level cell (MLC) flash is designed for lower cost applications and has a greatly reduced cycle count of typically between 3,000 and 5,000.
