Factors such as temperature & humidity have an impact on these drives. Moreover, environmental conditions and age of the drive also decide its life. SSDs can be considered more reliable in terms of portability as they are less likely to damage. Therefore, they’re not susceptible to physical damages. Hence, the SSDs rated with minimum write cycle would also last for years even if you write A write cycle is not equal to the one write from an application. MLC SSD has a write cycle limit between 3000 and 10,000 which is a high number. This denotes that an SSD would start failing after it crossed the limit of number write cycles. There are various factors on which reliability or the lifespan of drives depends, such as the amount of data written over the time, how you handle the drive, environmental conditions, age of the drive, etc.Īn SSD can sustain a limited number of write cycles in comparison to HDD which ideally has no read/write limits. They’re pocket friendly as they’re much cheaper than PCIe or M2 SSDs and are not very costly in comparison with some HDDs However, if you want a balanced deal, you can go for older SATA III SSDs which offer a fair speed and good durability. You’d get larger capacity at a much lesser price. Typically, for a given capacity, SSDs are much costlier than HDDs. While choosing a storage device the first thing that might strike your mind is the cost of the drive. The average speed of PCIe SSDs is around 1.2 GBps to 1.4 GBps, and some high-end SSDs can even deliver a speed of up to 2.2 GBps. Additionally, connecting an SSD with a faster interface such as PCIe enhances its speed even more. Some of the SSDs may even deliver a speed of 600MB/s. The average read and write speed of an SSD with SATA III connection is around 550 MB/s and 520 MB/s, Making simultaneous access to every cell which means data is read at a faster speed. Moreover, files are written sporadically across the cells. They don’t use rotating disk for reading/writing data, and hence the question of latency caused due to disk rotation never arises. On the other hand, data read/write technology in SSDs is entirely different from HDDs.
