Compared with traditional hard disk drives, a solid-state drive (SSD) uses flash memory to store data and it doesn't have moving parts. Limited SSD lifespan is controlled by program-erase cycles or P/E cycles. How to understand this? We compared SSD as a piece of blank paper, writing data to SSD is what using pencil to write information on paper. To verify how much information you have wrote, you can ask SSD benchmark tool for help. When you continue to write information on paper, one day the paper will be full of information. But you can use eraser to wipe the information and then write new information on paper again. This is similar to SSD, because when you want to write data to SSD which is full of data, at first the whole block must be erased and then you can write data. During erasing, your SSD will be wear and tear. Therefore, SSD lifespan is related with P/E cycles. SSD has many other differences features comparing to HDD, you can get more information on SSD vs HDD performance.
How to Extend SSD Lifespan
SSD is widely used by computer users due to its more advantages compared with traditional hard drives. However, the limited life time brings worries to users. Is there any way can release such problem? Don’t worry, you have ways to stretch and optimize SSD even though it has limited service time.
Hibernation is a common feature in operating system. When this feature is in use, the system memory will write the running programs and information to internal device. After you restart your computer, the system will reload the restored content into system memory and then your computer can recover to the state before you choose hibernation.
You can image that the different amount of system memory will use different storage space when you use hibernation. In other words, hibernation rings more writes to internal storage. So if you use SSD, hibernation will decrease the lifetime of SSD. In order to avoid this problem happens; you can turn off hibernation as follows.
1, type cmd in the Start Menu and then press Enter to open Command Prompt (run as Administrator).
2, enter powerrcfg.exe/hibernate off and press Enter.
Disable Page Files
Simply put, page file is storage space which on internal device. When an application needs more physical memory that the computer can’t provide, page file will be used.
It is not good for SSD use page file, because the size of page file changes dynamically which brings many writings to SSD. So if the memory used by you can’t reach the memory of your computer. There is no doubt that you need to disable page files to increase SSD lifespan.
1, right-click My Computer and then choose Properties.
2, choose Advanced System Settings.
3, click Advanced, choose Settings in the Performance filed and then select Change in the Performance Option.
On traditional hard drives, the sequentially stored data will be read faster than which is not sequential. But in fact data is not usually stored sequentially on hard drive. Defragging SSD can make data be in contiguous regions which dramatically improve the reading speed. However, SSDs don’t have moving parts and the location of data can’t affect the performance of SSD. Defragmentation is unnecessary for SSD. Besides, defragmentation can reduce the lifespan of SSD by taking up P/E cycles. So you should disable defragmentation to your SSD.
1, open My Computer and right click on SSD then choose Properties.
2, click Defragment now, then you will enter Disk Defragmenter.
3, In Disk Defragmenter, when scheduled defragmentation is available, click on the button of Configure Schedule and then turn off the schedule and click OK.
Besides, the method mentioned above, you can try your best to reduce different kinds of temporary files and cache to extend limited SSD lifespan. Using SSD in RAID 0 array can improve its performance as well. Aforementioned solutions also could be applied to increase lifespan of SSD like Synology SSD, Crucial SSD, etc. As for common users, as long as you have something mentioned above and you don’t write great data to SSD constantly, your SSD can be used for a long time. What’s more, to fully make use of SSD, you can use SSD for OS only and make HDD as storage device.
