Swapping your HDD for an SSD is among the greatest upgrades you may make to your PC to enhance its general efficiency. It is one of many first issues I like to recommend upgrading for an instantaneous enhance with out spending an excessive amount of cash. Nevertheless, not all SSDs are made equal, and a few are thought of to be higher than others. There are many issues to contemplate whereas searching for an SSD, however one factor that you could have heard essentially the most is checking whether or not your SSD has DRAM. Nicely, there isn’t any definitive solution to inform if an SSD has DRAM, however there are some things you are able to do to confirm the presence of DRAM in your SSD or the one you are planning to purchase.
Bodily examine the SSD for a DRAM chip
The easiest way to inform in case your SSD has DRAM is by bodily inspecting the unit to see if it has the DRAM chip on it. The dearth of software program to verify the presence of DRAM in your SSD leaves you with no choice however to bodily tear down the SSD to get to its internals and find the DRAM. You’ll be able to find the DRAM chip as a separate unit that rests between the reminiscence controller and flash reminiscence chips, as highlighted within the picture above. It might or might not have apparent markings or a label to point it is a DRAM chip, so search for a comparatively small rectangular chip sitting in proximity to the reminiscence controller. Under is a picture of a WD SN550 SSD to indicate you what a DRAM-less SSD appears like.

This is not a foolproof methodology both, as some SSDs might have DRAM built-in into the controller. It is also not the simplest factor to identify, particularly if you do not know how you can rigorously tear down the SSD to get via its heatsink and get a peek at its internals.
If you cannot bodily examine the SSD your self, then you can too depend on technical teardowns and opinions on-line to confirm the presence of DRAM. Alternatively, you may rely on group specialists over on the XDA boards and related on-line boards to examine if a specific SSD has DRAM.
Examine the specs of the SSD
Checking the specs listing of the SSD you intend to purchase can be a great way to confirm if it has DRAM. Not all producers affirm the presence of DRAM on the product, however most of them listing it in some capability as part of their specification sheet or advertising materials. Discover how the DRAM chip is distinctly highlighted within the promotional picture of the Samsung 980 SSD above? Most producers — if not all — will spotlight it as an vital characteristic, so maintain an eye fixed out for these. I additionally suggest trying up the product on different web sites and marketplaces to get a extra detailed specification sheet. Websites like PCPartPicker and johnnylucky.org have extra particulars a couple of explicit product that is sourced from varied portals and is usually up to date.
Not all producers clearly point out the presence of DRAM on their SSDs, so that you would possibly need to have a look at some key phrases like DRAM, and even SLC, QLC, and TLC NAND reminiscence to inform whether or not it is a DRAM or DRAM-less SSD.
Go for higher-end SSDs for DRAM
SSDs with DRAM value greater than DRAM-less SSDs in the marketplace, so it is protected to say that the higher-end and dearer SSDs on the market are typically those to hold DRAM. There is not any scarcity of SSDs with Host Reminiscence Buffer (or HMB) in the marketplace today that ship good efficiency at comparatively decrease costs. Nevertheless, they’re nonetheless not as performant because the SSDs with DRAM, particularly if you examine them with artificial benchmarks. SSDs with HMB designs aren’t essentially dangerous as they do not wrestle with sequential switch efficiency, however you may undoubtedly be stretching skinny with random transfers.
Closing ideas
The dearth of packages or benchmarking instruments that detect DRAM cache makes it a bit daunting to differentiate DRAM and DRAM-less SSDs. However it’s value highlighting that almost all trendy SSDs — no matter whether or not they have DRAM or not — ship nice efficiency for day-to-day utilization, and you do not have to go for the best possible SSD on the market to get dependable learn and write speeds. You’ll be able to try our assortment of greatest M.2 SSDs and SSDs for gaming, wherein we have highlighted each DRAM and DRAM-less SSDs which are value contemplating proper now in 2023.
