MX100 PACKAGING AND COMPONENTS
The MX100’s packaging is just a cardboard box matching Crucial’s typical blue and grey theme as seen with their other SSDs.
Included in the box is not only the 7mm thick 2.5″ MX100, but a 7mm to 9.5mm spacer you can attach to the drive if need be for size compatibility purposes. Furthermore and more interestingly, they seem to be taking note on what other companies have been doing when they include their migration software with their drives. Crucial is including Acronis True Image HD key with every MX100 drive as well.
The casing of the MX100 is a nice etched aluminum finish with the PCB screwed into the aluminum casing and then protected by an aluminum base plate.
Once we void the MX100 warranty by removing the casing, we get to see the beauty that lies inside. A green PCB that appears to look almost exactly the same as the M550.
There is a Marvell 8 channel 88SS9189 controller. A thermal pad attached to the aluminum casing rests against the chip to help dissipate heat.
This controller is a little more optimized than the previous 88SS9187 controller The M500 has and allows for better DevSLP support. DevSLP allows for very low power usage in sleep mode. The MX100, it will only use 100mW of power at idle. And when active, the drive will use up to 3.7W of power for the 256GB variant and up to 4.2W for the 512GB variant when transferring data.
On the PCB there are 16 modules of Micron NAND flash memory, as well as a single Micron cache memory chip on the front. By using the Micron FBGA Decoder, we can identify the 256GB memory as having the product number MT29F128G08CBCCBH6 and the 512GB memory product number being MT29F256G08CECCBH6. It is 16nm MLC NAND flash memory with each module being 16GB in capacity for the 256GB drive and 32GB for the 512GB drive. Although the total RAW capacity of these SSDs are 256GB and 512GB, usable storage space is only 238GB and 476GB respectively.
And finally, below we end our PCB tour with a close up of the power capacitor array that allows for the drive to stay on long enough to flush the DRAM buffer to the NAND in case of a power failure.
