Western Digital Blue SN550 (1TB) 2024: Review & Full Specs

Western Digital Blue SN550 1TB NVMe M.2 SSD

Western Digital Blue SN550 1TB NVMe M.2 SSD Description:

3D NAND SATA SSD with capacities of up to 4TB and improved reliability; One terabyte (TB) is equal to one trillion bytes when it comes to storage capacity. Depending on the operating environment, total accessible capacity varies.

  • MPN: WDS100T2B0C
  • Model: Western Digital Blue SN550
  • Interface PCIe Gen 3
  • Connector M.2
  • Sequential Read Performance 2400MB/s
  • Sequential Write Performance 1950MB/s

Sequential read speeds can reach 560MB/s, and sequential write speeds can reach 530MB/s. Megabytes per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second when used for transfer rate or interface.

This M.2 SSD features a PCI Express (NVMe) interface and will function only if your system supports PCIe/NVMe. Check the manual for your laptop or motherboard for more information.

WD’s latest NVMe SSD aims to round out the company’s portfolio, but it also signals the end of SATA SSDs. WD recently released the WD Blue SN500 to complement the WD Black SN750. Unlike the WD Black, which is aimed at consumers seeking one of the best SSDs on the market, the Blue SN500 is aimed at resellers, system builders, or any consumer on a tight budget.

The WD BlueTM SN550 NVMeTM SSD can outperform our best SATA SSDs by more than four times. Use the high speeds of this powerful internal drive to do more faster, whether you’re working, creating, casual gaming, or processing large amounts of data.

How much does the WD Blue SN550 1TB NVMe M.2 SSD cost in the USA?

In America, the current price of the WD Blue SN550 1TB NVMe M.2 USD is $141.94.

Pros & Cons

  • The WD Blue lasts longer than the WD Green and other SSDs with regular flash memory due to the 3D NAND memory.
  • Because the SSD is energy-efficient, it runs cooler and consumes less power.
  • Because it has a B and M key, this SSD is compatible with any M.2 connection.
  • To better protect your files, the SSD does not support hardware encryption.

M.2 NVMe SSDs are faster, smaller, and, in some cases, less expensive to produce. After all, they’re just PCBs with components attached. They do not require an external casing or an additional connector, as SATA drives do. However, these are not the most significant burdens on the total cost of manufacturing an SSD; DRAM significantly raises the price of both M.2 and SATA SSDs.

DRAM is found in most modern SSDs, at least the better-performing ones, which makes the WD Blue SN500 stand out. It outperforms SATA SSDs and competes well with an entry-level NVMe SSD, but it does not include an expensive DRAM chip. It also does not squish system resources like the Toshiba OCZ RC100 NVMe Host Memory Buffer feature does.

WD, on the other hand, decided to try something new.

Recently, we invited us to its headquarters for a briefing on the WD Black line of SSDs, as well as to see multiple proofs-of-concept SSDs. WD has conducted various tests to characterize better and understand client SSD workload patterns, allowing for a more cost-effective allocation of system resources. Two of these tests involved determining how much DRAM and SLC cache an SSD requires for the majority of PC workloads.
