Sequential speeds refer to a pattern in which large blocks of data are written in adjacent locations on the surface of the drive. This type pattern is typical for large files such as video, music and high definition images. So if you frequently work with such files, you should go for SSDs with higher sequential write speeds. In the case of SSDs offering 1000-2000 MBps speeds, they will at most offer you slightly better performance than an HDD but will be easier on the pocket than the high speed, high-performance SSDs.
Along with Intel’s brand value, the SSD 660p Series features Quad (4)Level Cell NAND as compared to Triple (3) Level Cell found on many SSDs. It features speeds of 1800MBps on both (read and write). Intel SSDs allow twice the capacity in identical footprints for quick computing functionalities. There is one notable issue though- when the drive runs out of cache, write speed drops drastically- even to the level of a slow hard drive.
XPG SX6000 1TB offers read/write speeds of 1000/ 800 MBps. It utilizes 3D NAND technology and leverages PCIe3x2 interface with NVMe 1.2 supported for enhanced performance. It comes with a DIY heatsink for better cooling options and long life. The drive also supports SLC Caching and DRAM Cache Buffer to help maintain optimal performance during heavy use. Based on various benchmarks, this model is a good choice providing a decent upgrade at an affordable rate for gamers, video professionals and ilk.
Intel SSD 760p Series (1TB) offers high performance and speed with its 3D NAND technology. The performance of this SSD drive is almost twice the capacity of other SATA SSDs but with a 50% reduction in your power consumption. The higher performance and reduced cooling are due to the NVMe interface. It supports AES 256-bit self-encryption for secure computer usage. The SSD comes with a 5-year manufacturer's warranty for technical errors and other faults. You can install Intel SSD with its simple plug-in feature that enables its easy integration into the M.2 key slots on all motherboards.
Kingston’s A1000 SSD supports PCIe NVMe Gen 3.0 x2 interface, for enhanced performance and offers read and write speeds up to 1,500MB/s and 900MB/s respectively. Due to Kingston’s close ties with Toshiba and Phison, the drive features Toshiba's latest 64-layer 3D TLC NAND flash memory and Phison's second-generation PS5008-E8 NVMe SSD controller for enhanced performance. It has a quality cooling system thanks to its shock-vibration resistant capacity. It comes in a 22x80mm design making it a great fit for thinner notebooks and systems with limited space.
