Today we are taking a look at the WD Bluish SN550 1TB SSD. This is a mainstream drive from WD featuring PCIe 3.0 x4 connectivity, a WD designed controller, a DRAMless design, and TLC NAND. This is the first DRAMless SSD that I take evaluated, though STH has looked at to the lowest degree one other in the by.

WD Bluish SN550 1TB Overview

The WD Blue 1TB comes in a single-sided Chiliad.2 2280 (80mm) grade gene.

The PCB for the SN550 1TB is almost barren, sporting merely a single NAND parcel and the controller, which are physically distant from each other on the PCB. Supposedly this separation is to allow for easier thermal management, so we will accept a wait at the temperatures later on. As noted, at that place is no DRAM cache; the controller itself contains a small amount of SRAM that is managed by said controller. Nosotros will look to our performance benchmarks to run across if this system holds upwards.

Unsurprisingly given the sparse population of the front of the drive, the rear is completely arid. As a consumer bulldoze, at that place is no power loss protection (PLP.) You tin read a bit more than most why PLP is important in some server workloads in our slice What is the ZFS ZIL SLOG and what makes a proficient one. That looks at a specific case just has a few diagrams and an caption around what goes on with these drives when they do and do non have PLP.

WD Blueish SN550 1TB Specs

The WD Blue line of TLC based SSDs ranges from 250GB up to 1TB in size.

Our review unit is the summit of the line unit from the WD Blue NVMe line, offer the highest performance and endurance. The advertised performance numbers are very pocket-sized though, and not intended to compete at the high stop of even other PCIe iii.0 drives. On the other hand, the five-twelvemonth warranty and endurance numbers are both proficient.

CrystalDiskInfo tin give u.s. some basic information about the SSD, and confirms we are operating at PCIe 3.0 x4 speeds using NVMe i.4.

Exam System Configuration

We are using the following configuration for this test:

Motherboard: ASUS Prime X570-P
CPU: AMD Ryzen 5 3600 (6C/12T)
RAM: 2x 16GB DDR4-3200 UDIMMs

Our testing uses the WD Blue SN550 1TB as the kicking drive for the organization, installed in the M.2_1 slot on the motherboard. The bulldoze is filled to 85% capacity with information and so some is deleted, leaving around sixty% used space on the volume.

Next, we are going to get into our functioning testing.
