QVO uses different encryption for your data and a different set of "pathways" to retreive data, unfortunately QVO is typically slower than EVO, so make sure you spend your money wisely and buy the EVO model
Sorry, there was a problem. Please try again later.QVO is a terrible drive that isn't worth two wooden nickels. The QVO write speed is worse than a mechanical drive. What does that mean to you? It means that putting data onto the drive is slower than a corpse decomposing in a bog. Reading the data once it's on there is no problem. Getting the data on there, manipulating the data once it's on there, that's the problem. Imagine the fattest person you've ever seen, now imagine them seeing an ice cream truck. That's the read speed, they noticed that ice cream right away. Now imagine that person running uphill in 100 degree weather, in a parka, with no shoes on, after that ice cream truck. That's the write speed of the QVO, that's that drive trying to get the data.
Sorry, there was a problem. Please try again later.The QVO model uses a different type of NAND memory for storage. QVO memory is 4 bits of information per cell vs 3 bits for the EVO models. The QVO models and somewhat cheaper, bur also slower in read and write speed. Also, the QVO drive have a much shorter lifespan the the EVO drive.
Sorry, there was a problem. Please try again later.QVO uses QLC, i.e. 4 bits are stored in each NAND flash cell. EVO uses TLC, or 3 bits stored in each NAND flash cell. The tradeoff is in storage space in one dimension and endurance (i.e. # of writes before drive failure). While QLC will store 33% more data in a given amount of silicon, it will fail much faster, simply because it is harder to distinguish between 16 different cell values (QLC) vs. only 8 different cell values (TLC). If you are only rarely writing to the drive, QLC is probably fine. But if the drive will be used intensively, keep your data safer by using TLC (or even better/more expensive MLC or SLC).
Sorry, there was a problem. Please try again later.GoodChance192cc: The biggest difference between the EVO and QVO drives is flash memory. The EVO product line makes use of TLC NAND (3 data bits/cell), while the QVO line makes use of QLC (4 data bits/cell). Both the QVO and EVO drives make use of Samsung’s Intelligent TurboWrite system. If you’re looking for an SSD, both the QVO and EVO product lines are a great choice. We're here to help you find the right drive for your specific needs.
