![]() Early revisions were manufactured using 3D-MLC NAND, while later revisions were made using 3D-TLC chips (these drives can be identified by their firmware version, which is different from firmware used on the MLC-based revision). There have been mixed reports about this model. So let’s check our first SSD: a 480GB Crucial BX300 drive. Note: you must launch the tool with administrative privileges ( Run as administrator). If you’re analyzing a SATA drive, use “flash_idata.exe”. We found that, at least on some systems, the tool can work without such restrictions. ![]() The tool officially supports disks that don’t have any partitions on them, or at least don’t have a drive letter. ![]() Note: Marwell controllers are not supported by these utilities.ĭownload and save the tool you’re going to use on some disk you’re not going to check (e.g. You will only need the one utility corresponding to your controller manufacturer. In order to determine the exact model of the controller as well as NAND flash configuration you’ll need a set of command-line tools: Phison Flash ID, Silicon Motion Flash ID, and SandForce Flash ID. You can look up the model’s controller manufacturer by checking out the reviews for your SSD. Common manufacturers of SSD controllers found in many SSD drives are Marwell, Phison, Sandforce and Silicon Motion. How can you tell which NAND configuration your particular SSD drive employs and whether or not it lives up to your expectations? Read along to find out.įor starters, you’ll need to know who made the controller in your SSD. We’ve seen well known SSD manufacturers switching from reliable MLC NAND to planar TLC trash within the same model (and zero notice to potential buyers). While some OEMs do note the change at least in the revision number, the rest will just quote the small print allowing them to “change specifications at any time without prior notice”. Quite a few manufacturers play tricks with consumers, releasing a certain SSD model with top notch specifications only to downgrade them at some point during the production cycle (but certainly after receiving its share of glowing reviews). In that article, we assumed that manufacturers’ specifications of certain SSD models remain similar for a given SSD model. In our previous article Why SSDs Die a Sudden Death (and How to Deal with It) we talked about SSD endurance and how it’s not the only thing affecting real life reliability.
