All the SSDs are not created equal. A Consumer grade 4TB SSD could be cheaper than an Enterprise Grade 2TB SSD for example. We specialize in High Endurance Enterprise Grade SSDs. Enterprise Grade SSDs have higher endurance ( Measured in TBW or DWPD), top noch performance and often overprovisioning. Further Enterprise SSDs are available not only in 2.5" SATA and M.2 NVMe but in a number of other formats like 2.5" Format SAS and SATA, M.2 - SATA and NVMe, U.2 NVMe and E1.S NVMe. We integrate Kingston and Exascend flash in QNAP and Synology to have All Flash Arrays .
