DRAM-less SSD looks good for computers which mostly be used for displaying a slide show presentation on a TV, using to play music files on a PC, basic web browsing and gaming, or as a upgrade from a slower hard drive on a older lowend PC.
Users of DRAM-less SSD may also have better battery life since there is no DRAM chip which may use up some more electricity when ON. DRAM-less SSD use less power than a hard drive which are mostly found on older lowend PCs.
But, users need to backup your files more often on a DRAM-less SSD. It is always a good idea to backup your files even if your SSD has DRAM since the DRAM, and other parts can also break because of old age, rust/oxidation, overheating, and random accidents like spilled water or fire damage.
I feel some users upgrading from a older laptop 2.5 inch hard drive with a slower 5200RPM speed, and 2MB cache will feel DRAM-less SSDs are a decent speed improvement from their older and slower laptop hard drive. Desktop 3.5 inch hard drive with a 7200-10000 RPM speed, and 32MB cache may not see as big of a drive speed improvement upgrading to a DRAM-Less SSD.
Newer DRAM-less SSD are faster and more reliable than very old SSDs made many years ago, and have more storage space than a 32GB SSD drive found in cheap laptops and tablets.
For lightweight operating systems like Puppy Linux, the speed difference may not be as noticeable since lightweight operating systems sometimes gets entirely loaded to the faster RAM after start up.
