Review on Crucial BX500 480GB SATA Internal SSD 💾 with 3D NAND Technology, Up to 540MB/s - CT480BX500SSD1Z by Anden Turn

Yes, it is without DRAM. Yes, this is usually seen as a disadvantage. This is usually the case in a SATA III system. But when used in an older system it's perfect for SATAII (3Gb/s) and actually faster than the MX500 (with DRAM) on SATA-II. On SATA-III, this drive will definitely show how slow it can be. , but read/write speeds are still more than double those of the fastest spinning SATA drives. In the same old AMD Phenom II X4 955BE system that hits the max SATAII speed of 3Gb/s, when comparing this drive alongside the Mx500 this DRAM smaller BX500 is 250GB at 269MB/s reading and 252MB actual write faster / With. MX500 on the same system has about the same read speed but is actually the slowest at just 220MB/s on this system, both using Crystal Disk Mark 6. Even faster with DRAM and SLC caching, but when the SATA connection seems to be a bottleneck is that the BX500, with its DRAM-free controller and SLC caching, is better able to write faster without slowing down. IOPS in 4k benchmarks are roughly the same between drives on the same SATAII connection. When used on a SATAIII 6Gb/s connection, the MX500 is faster in every respect - nearly 100MB/s in the write test, with read only taking precedence over random reads, sequential reads are essentially identical. But if you only need a boot disk and only have a SATAII 3Gbps connection (rather than the faster 6Gbps SATAIII), there's not much point in spending the extra 40% on an MX500 with DRAM. .If you are using modern system with SATAIII 6Gb/s, please buy MX500 with DRAM. But it's not a bad drive to upgrade from a rotary drive over a SATAII 3Gb/s connection.
