more What’s the difference between SLC, MLC and TLC? more What is 3D XPoint and how fast is it?ģD XPoint is the name given by Intel and Micron to their jointly developed, revolutionary storage technology as employed in Intel’s Optane memory. They run on top of transfer interfaces such as PCIe or SATA (spoken, written).

NVMe, AHCI and IDE are transfer protocols (languages). more What’s the difference between SATA, PCIe and NVMe? NAND and V-NAND are both types of flash memory which is a class of non-volatile memory that retains data even in the absence of an electrical current. more What’s the difference between NAND and V-NAND? more What is sequential write speed?Ī measure of how quickly large files can be written to a device. more What is sequential read speed?Ī measure of how quickly large files can be read from a device. most music, video and image file formats. more What is incompressible data?ĭata that cannot be compressed e.g. The number of simultaneous requests on a drive's request queue. more What is the SSD value for money rating?Ī measure of real world consumer performance and capacity per unit cost. more What is 4K 64 thread write speed?Ī server orientated measure of a drives ability to write 64 files in parallel. Yes, mostly on shallow queue random 4k operations. more Can CPU power saving states (C1,C2,C3) impact SSD speed? more What is the effective SSD speed index?Ī measure of how well an SSD performs under typical consumer workloads. more How is the AS SSD write score calculated?īenchmarks write workloads with an emphasis on deep queue depth (server) writes. more How is the AS SSD read score calculated?īenchmarks read workloads with an emphasis on deep queue depth (server) reads. How is the AS SSD total score calculated?īy taking a combination of speed readings with a strong emphasis on deep queue depth (server) IO.
