ADATA XPG SX8000 512 GB Review 16

ADATA XPG SX8000 512 GB Review




Today, we are reviewing the ADATA SX8000 SSD in its 512 GB variant. ADATA was one of the first players to join the SSD market, with an even longer history in DRAM and general flash memory, like USB storage.

The SX8000 is a mid-range NVMe M.2 based SSD that uses 3D MLC flash with a PCI-Express x4 Gen 3.0 interface. As the controller, ADATA has chosen a Silicon Motion SM2260 with eight flash channels. In addition to a DRAM buffer, the drive also features pSLC (pseudo-SLC), which runs a portion of the MLC flash in SLC mode for increased write performance.

The SX8000 is available in capacities of 128 GB, 256 GB, 512 GB (this review), and 1 TB. Warranty is set to five years for all these models. We reviewed the version with a heatsink, but the same drive is also available without a heatsink.

Inside the package you will find just the SSD; no other accessories or documentation is included.

The Drive

The drive uses the M.2 2280 form factor, which means it is 22 mm wide and 80 mm long. On top of the SSD, ADATA has glued a thin metal heatspreader. You can also find the SX8000 without that heatsink, possibly at slightly reduced pricing.

SSD Interface Connector

Like most M.2 NVMe SSDs, the ADATA XPG SX8000 uses a PCIe x4 3.0 interface.

I ripped off the heatspreader, which really is just a thin piece of flexible metal that's glued onto the SSD to provide a little bit of cooling for the controller and two flash chips on the front side of the PCB.

You will find the SSD controller and four flash chips on the PCB. Two DRAM chips are also present to provide the SSD controller with RAM and soak up write bursts.

SSD Controller

The Silicon Motion SMI 2260 controller is the company's first PCIe NVMe controller.

SSD Flash Chips

The four MLC flash chips are rebranded to show ADATA markings only. My best guess is that these are Micron 3D MLC.
