得益于超快的速度和越来越低廉的闪存价格,SSD大有成为PC标配之势。不过受制于先前TLC闪存在使用寿命、读写速度等方面的劣势(图1),使得TLC闪存SSD虽然在价格方面比MLC闪存产品有很大优势,但许多朋友仍在拼命纠结中。如在价格相近的情况下,240GB TLC和120GB MLC这两种SSD究竟该选谁呢?寿命没必要纠结MLC和TLC这样不同闪存颗粒间存在着寿命差异是众所周知的事(图2),其中MLC的擦写寿命(P/E)约为3000次~10000次,TLC理论上约为
Benefit from the ultra-fast and lower prices of flash memory, SSD has become the standard PC trend. However, due to the shortcomings of previous TLC flash memory in terms of service life, read and write speed (Figure 1), TLC flash SSDs have great advantages over MLC flash products in terms of price, but many friends are still desperately struggling. For example, at similar prices, who are the two SSDs, the 240GB TLC and the 120GB MLC? LIFE DOES NOT REQUIRE IT Life-span differences between different flash memory particles such as MLC and TLC are well known (Figure 2). MLC Of the erase life (P / E) is about 3000 to 10000 times, TLC theory is about
