It would only take one moving part to fail to render the drive useless. Every time data is written or read, the spindle is read by the mechanics within the drive. A solid state drive opened up looks like a circuit board.Īn HDD relies on moving parts for the drive to function. This means that if you will rarely place new files on your drive, the SSD will last a long time. NAND cells degrade with every write on the SSD drive. NAND is the technology that is used by SSD drives. SSD drives typically have a factory guideline for lifetime of the NAND. Some assume that because solid state drives have no moving parts, they last a lot longer.

To find out which WD Drive series is best for you check out our posts comparing the WD Drive Series SSD vs HDD Lifespanīoth SSD drives and HDD’s have their advantages and disadvantages when it comes to hard drive life span. Please note: Standard HDD types are specially designed for certain purposes. Recommended HDD for maximum speed: WD Black Series Sizes Available: 250 GB, 500GB, 1TB, 2TB, 4TB Recommended SSD for maximum speed: Samsung 860 EVO For most users a drive with faster read/write speeds is recommended.īelow are links to TekHattan recommended consumer drives for purchase based on maximum speed for both HDD and SSD’s.

For basic PC usage, one could perhaps get away with using a lower speed drive. Of course, an SSD with close to 550 MB/s read/write speed will cost more.įor certain tasks, maximum read/write speed is not needed. The read/write speed you will achieve when using an SSD or HDD will vary depending on the model chosen. These technical differences ensure that HDD’s cannot compete with SSD’s on speed. SSD’s function on flash memory while HDD’s write to a physical disk. There is a major technical difference between SSD’s and HDD’s. When it comes to SSD vs HDD speed, the solid state drive is the clear winner. On the other hand, a typical SSD will deliver read/write speed of between 200 MB/s to 550 MB/s.Īs noted above, an SSD can deliver a much better read/write speed to an HDD. The read/write speed is the most important statistic when it comes to HDD vs SSD speed.Ī typical 7200 RPM HDD will deliver a read/write speed of 80-160MB/s.

While the connection speed is commonly used in the industry, a hard drive will not deliver those speeds. One should not rely much on the connection speed, usually 6GBPS.

While SSD’s are great, they are not the best option for every scenario. This article aims to compare the differences between hard disk drives (HDD’s) and solid state drives (SSD’s). We will compare and contrast SSD vs HDD speed, lifespan, and reliability in this article.įinding the speeds of an SSD or an HDD can be confusing.

This is a major difference that now makes SSD hard drives a viable option for everybody. It is now possible to buy a 1TB SSD hard drive for around $150. To obtain an SSD, the cost was astronomical. With the exception of the last couple years, SSD’s have been out of the price range of most consumers and business owners.
