What To Know
- The SanDisk Ultra 3D SSD boasts an endurance rating of 150 TBW (Terabytes Written), while the Samsung 870 QVO has an endurance rating of 360 TBW.
- Both the SanDisk Ultra 3D SSD and Samsung 870 QVO feature a DRAM cache, which acts as a buffer between the SSD and the system memory.
- If you need a high-capacity SSD at a budget-friendly price, the Samsung 870 QVO is a suitable choice.
In the realm of storage devices, the SanDisk Ultra 3D SSD 1TB and Samsung 870 QVO 1TB stand as formidable contenders. Both offer ample storage capacity, but their underlying technologies and performance characteristics set them apart. This comprehensive comparison will delve into the key differences between these two solid-state drives (SSDs), empowering you to make an informed decision when choosing the ideal storage solution for your needs.
Performance
The SanDisk Ultra 3D SSD employs TLC (Triple-Level Cell) flash memory, while the Samsung 870 QVO utilizes QLC (Quad-Level Cell) flash memory. QLC offers higher storage density than TLC, allowing for larger capacities at a lower cost. However, this comes at the expense of write performance and endurance.
In sequential read and write operations, the SanDisk Ultra 3D SSD outperforms the Samsung 870 QVO. It delivers read speeds of up to 560 MB/s and write speeds of up to 530 MB/s, compared to the 870 QVO’s read and write speeds of 560 MB/s and 530 MB/s, respectively.
Endurance
Endurance refers to the number of times data can be written to an SSD before it fails. The SanDisk Ultra 3D SSD boasts an endurance rating of 150 TBW (Terabytes Written), while the Samsung 870 QVO has an endurance rating of 360 TBW. This means that the 870 QVO can handle more data writes over its lifetime before reaching its end of life.
Cache
Both the SanDisk Ultra 3D SSD and Samsung 870 QVO feature a DRAM cache, which acts as a buffer between the SSD and the system memory. The SanDisk Ultra 3D SSD has a 512MB DRAM cache, while the Samsung 870 QVO has a 1GB DRAM cache. A larger cache improves performance by reducing latency and increasing the speed of data access.
Form Factor
The SanDisk Ultra 3D SSD and Samsung 870 QVO both come in the standard 2.5-inch form factor. This makes them compatible with most laptops and desktop computers. However, the SanDisk Ultra 3D SSD is also available in an M.2 form factor, which is ideal for ultrabooks and other compact devices.
Warranty
SanDisk and Samsung offer different warranty periods for their SSDs. The SanDisk Ultra 3D SSD comes with a 5-year limited warranty, while the Samsung 870 QVO comes with a 3-year limited warranty. A longer warranty provides peace of mind and protects you against potential failures.
Price
The SanDisk Ultra 3D SSD and Samsung 870 QVO are priced similarly, with the 1TB models typically retailing between $100 and $150. However, the price may vary depending on the retailer and current market conditions.
Final Note: Choosing the Right SSD for You
The choice between the SanDisk Ultra 3D SSD 1TB and Samsung 870 QVO ultimately depends on your specific needs and priorities.
- If you prioritize performance and endurance, the SanDisk Ultra 3D SSD is the better option.
- If you need a high-capacity SSD at a budget-friendly price, the Samsung 870 QVO is a suitable choice.
- If you require a compact form factor for a laptop or ultrabook, the M.2 version of the SanDisk Ultra 3D SSD is recommended.
