Silicon Power UD80 M.2 2280 1TB PCIe 3.0 SSD Review

Storage/SSD by stefan @ 2022-07-15

UD80 1TB PCIe 3.0 SSD from Silicon Power incorporates the MAXIO MAP1202 controller which offers a low-cost DRAMless solution and is paired with four 3D NAND ICs from a brand we could not easily identify. As a caching solution, HMB is used so the performance of the drive is strictly dependent on the computer configuration. The drive can be picked up with capacities from 250GB and up to 2TB and thanks to the fact that it functions with excellent thermals, it can be installed in most compatible laptops as well!

Packaging, A Closer Look

Silicon Power never ceases to amaze us in terms of storage products in their portfolio. The mainstream segment gains another member with the UD80 NVMe, which comes with rated speeds regarding reads of about 3400MB/s and writes of about 3000MB/s and functions on a PCIe 3.0 bus, helped with caching by the HMB (Host Memory Buffer) technology.


The drive is shipped inside a simple cardboard layer with a transparent plastic interior, which allows the potential buyer to see how the drive really looks like instead of a photo. Here, Silicon Power highlights the warranty UD80 gets but also the total capacity of the SKU:




On the back side, we will note the power rating, addresses of the SP Worldwide offices but also the product code name and serial number:




After removing the cardboard layer, we ended up with the transparent plastic protective mold:




The frontal area of the UD80 PCB is covered by a large sticker, which comes with the capacity, model name but also the serial number, for easy identification:




On the back side there are no components:




After removing the sticker, we will be able to take a closer look at the main components: we do have here four 3D NAND ICs, but also a controller we haven’t seen before:




To be more exact, the controller is marked as MAXIO MAP1202, made by MAXIO Technology (Hangzhou). This controller does not support onboard DRAM cache but was specifically designed for HMB. JMicron spun off its SSD division to MAXIOTEK Corporation, a Taiwan-based company which designs and markets SSD controllers, if you were curious about the company's background:




The 3D NAND ICs are not easily identifiable by the lengthy code name printed on it:
