Review on Upgrade Your Storage with ADATA SU630 240GB Internal SATA SSD from Ultimate Series by Leslie Matlak

At the low price I paid for this drive, the speed is fine for normal laptop or desktop use, obviously much better than using a traditional hard drive. Even the smallest size of this hard drive is very fast. Lifespan is lower than other drives you can buy, but that shouldn't be a problem for normal laptop or desktop use, just web browsing/document editing and other basic tasks for a few years until you which still does not replace computers in question. .This is one of the first QLC drives on the market. QLC stores 4 bits per cell compared to previous TLC (3 bits per cell) and MLC (2 bits per cell). Due to the difficulty of storing more bits in a cell, the number of times each region can be reused/overwritten is less compared to TLC/MLC, but modern SSDs do a good job of evening out wear across the drive, so it shouldn't be. For normal use in a laptop or desktop computer this will not be a problem for a number of years, but this drive should not be used in a server or in a situation where the entire drive is frequently erased or overwritten. There is a good short news article. on anandtech about this particular drive, who mentioned that it uses Intel's NAND, which should be of very high quality since Intel is already using their QLC NAND in the drives it sells to large enterprise customers. The drive uses a Maxio controller with pseudo-SLC caching, which seemed to work well as the drive met its advertised write performance. I bought a 240GB drive which is the smallest size because I only use it in my work laptop. Even though the 240GB version is the smallest size, it's still very fast and just as fast as the larger sizes. The hard drive did not get hot at all when running Crystal Diskmark for several minutes. As you can see in the attached image of Cystal Diskmark results, it reads at 560MB/s and writes at 478MB/s, which is slightly faster than the specs and almost as fast as SATA3-600MB/s allows. I ran Crystal Diskmark an hour after installing Windows 10, so the hard drive may have had time to fully refresh the cache.
