Why this configuration
A 128GB MLC DRAM SSD is a specific spec configuration. It narrows the field to one set of characteristics so you can compare like with like.
At 128GB this is really a boot or cache drive rather than a main library.
Usually chosen for: a particular build requirement.
Good fit: workstation and creative loads that hammer random I/O.

The parts, explained
128GB suits a boot drive or a light secondary disk.
MLC NAND is older and costs more per gigabyte, but is very durable.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
Common questions
How do the links to Amazon work here?
1 of the 33 drives listed have a direct product link; for the rest we link an Amazon search on the manufacturer part number, which lands on the right listing. We deliberately don't display stock or prices on this page — check both on Amazon, they change constantly.
