Recently SSD disk has become popular among computer users who are looking for better performance due to users are attracted by SSD’s advantages of faster data access, less power usage and less noisy compared with traditional hard drives. When people decide to buy SSD, many things related with the performance and capability of SSD should be taken into consideration such as the material of NAND memory, memory controller, interface, and SSD’s managing firmware. Besides these factors, SSD size is also concerned by lots of users. In order to help you choose the right SSD size you should pay attention to the following things.

How Much Do You Want to Spend?

Traditional hard disk drive store data on spinning platters, however, SSD use NAND flash memory and it stores data on memory chips. Besides SSDs have no moving parts and this makes data access more efficient and faster. These differences compared with HDD make SSDs are more expensive. Although most of people pursuit high storage space, you have to take everything into consideration. That’s to say you should keep money into your mind. The larger size you want, the more you will pay. For example, on amazon, Intel SSD with 60GB (drive only) capacity is $129, 180 GB (drive only) is $235. The price of SSD with various sizes is very different; it is wise for you to choose suitable size for you.

What Do You Plan to do with SSD?

It is well acknowledge that SSD has fast data access and booting time. In order to demand the need for fast speed many users select SSDs. When you decide to use an SSD, you should make sure what do you want to do with SSD? For instance, if you want to SSD be dual-drive configuration. That’s to say you only need an SSD which can store your current operating system, usually-used documents, frequently used applications and page files. The other data you can store on HDD. In this way, the main data are stored on SSD which can speed up the data access and boot time at a certain degree. However, if you want to replace HDD with SSD, you must clearly know how much storage you really require. There is no need to buy a larger SSD than you really need.

What Size to Choose?

The advice is you’d better choose the SSD which is as large as your present hard drive. If it is expensive for you, you can look at your present hard drive. If half of your hard drive is empty, you can buy a smaller one to use dual-drive configuration. However, if you buy a new computer, the 512GB SSD is expensive, but it will be much cheaper if you gain your computer with a hard drive and replace it with a larger SSD than getting a smaller SSD immediately. However, it wouldn’t be a problem if you purchase a SSD with small capacity because you can use specialized software to clone SSD to SSD later.

When you buy SSD, besides SSD size you should pay attentions to other things: TRIM which enables operating system to tell SSD the data on which block is no longer useful and can be erased; MLC or SLC which are two kinds of flash memory. MLC is more widely used and cheaper but it has less rewritten times. SLC is more expensive but much faster, reliable and has longer lifespan; SSD has limited lifespan thanks to flash memory can be written on limited times. So lifespan is also the factor you should take into consideration. By the way, you can optimize the SSD using professional SSD optimization software after purchasing one. It is good for SSD maintenance.

When you have chosen SSD, the next you may do is finding a way to install OS to SSD. The common way used by many users is reinstalling OS on SSD. This method may be troublesome for you. Fortunately free AOMEI Partition Assistant Standard can help you only migrate OS to SSD without reinstalling system.
