Professional 2.5-inch SATA SSD, specifically designed for continuous operation within NAS systems and server infrastructures, requiring stable performance under high I/O volumes and constant read/write cycles. Unlike standard consumer drives, this model is geared towards robust performance under high and constant load scenarios, including real-time transaction processing (OLTP), multi-user environments, data visualization, and even 4K/8K video editing.
The WD Red SA500 is built on reliable 3D TLC NAND memory, offering higher endurance compared to QLC solutions, especially under intensive write conditions. The use of the Marvell 88SS1074 controller allowed for balanced performance and stable operation, crucial for NAS and professional tasks. Maximum read speed reaches 560 MB/s, and write speed reaches 530 MB/s, effectively hitting the ceiling of SATA III interface capabilities.
However, the model's key advantage is not in peak performance but in stable behavior under prolonged load, including situations of high drive utilization and multiple parallel requests. A 2 million hour MTBF rate is another testament to the WD Red SA500's design for long-lasting and predictable operation in server environments. Despite the lack of precise TBW and IOPS values, the five-year warranty confirms the manufacturer's confidence in the device's durability.

Red equals reliability
WD Red SA500 is a new line of solid state drives from 500 GB to 4 TB designed for 24/7 operation. Includes models of both the classic 2.5-inch form factor and the modern M.2, in both cases with a SATA3 bus. The main scope of these SSDs are NAS servers, that is, multi-disk network file storage. However, nothing prevents the Red SA500 from being used in both desktop PCs and laptops.
dual core controller
The Red SA500 is based on perhaps the best "old school" SSD controller — Marvell 88SS1074. It has two ARM architecture cores, eight channels of flash memory and supports external RAM cache chips. All this together allows him to develop the speed of reading and writing random files up to 95K and 85K IOPS (input-output operations per second), respectively. This parameter is especially important for those who often work with local databases (DBMS) containing a myriad of small files.
Selected Memory
The sequential read and write speeds of the Red SA500 also did not let us down: 560 and 530 Mbps, which is the practical limit of the SATA3 bus bandwidth. All thanks to the selected chips of SanDisk BICS3 64-layer 3D TLC flash memory (we remind you that SanDisk semiconductor factories are now Western Digital). A separate Nanya buffer RAM chip adds even more responsiveness to the system.
Universal Soldier
In general, the WD Red SA500 is a fast (by SATA SSD standards), reliable (600 TB overwrite resource for the 1 TB model) and, most importantly, a versatile solid state drive. It is equally well suited for NAS storage, work or gaming desktops, and most laptops. The only exceptions are thin ultrabooks, which simply do not have enough space for a 2.5-inch drive. It is for such cases that the M.2 version of the Red SA500 is provided. But be sure to check if a specific ultrabook supports an M.2 SATA SSD, or if an M.2 PCI-E is required, like the WD Black SN750.
