A high-capacity SATA 3 SSD for use in standalone Network Attached Storage that provides fast access to stored data. It is positioned as a product of the upper price category from the 2019 WD Red SA500 family. It has an impressive capacity (4 TB), which is quite comparable with the capacity of HDD-drives of the WD Red line. However, in this case, the device has significantly smaller overall dimensions (form factor 2.5″, 7 mm), much more modest weight and radically better energy efficiency.
Another important advantage of the WD Red SA500 WDS400T1R0A SSDs is their complete noiselessness, which greatly simplifies the task of creating a quiet network attached storage (NAS) for home use. Marvell 88SS1074 controller with DRAM buffer, support for high-speed SLC caching, progressive LDPC encoding, TRIM and SMART technologies provides impressive I / O performance and low latency. These drives are specially designed and tested for use around the clock. Efficient caching algorithms make them an excellent choice for OLTP databases, multi-user environments, photo rendering, 4K/8K video editing, and more. .36 TB of data.

My laptop got a "second wind". I bought my DELL Inspiron 5767 about three years ago, and it still has a pretty sturdy configuration: CPU Core i7 with Intel 620 graphics processor, 8Gb DDR4 RAM, discrete graphics card AMD R7 440 with 4Gb DDR5 RAM on board. However, technology does not stand still and for some programs this configuration is already outdated. Considering I've recently gotten into video editing, for Adobe Premiere PRO and Adobe After Effects, this configuration wasn't very solid even when I purchased the laptop, and the latest versions of Premiere and After Effects refuse to work with these graphics processors. Also, a serious obstacle for comfortable use of this software was the drive installed in the original configuration: HDD Toshiba 1Tb, 5400 prm. But working with it was still somewhat tolerable until I "clicked" the computer case right above the area where the disk was located. I'm amazed the disk lasted another whole three hours after that... The service center technician turned out to be a shifty character and installed a similar HDD to the one that failed, but used, which I found out very quickly. I had to have a preventive conversation with both the technician and his manager, and as a result, the laptop was "equipped" with another 8Gb RAM and this technical marvel. I admit: I am absolutely thrilled! This device "ingested" 350Gb of backups in an hour, all without any loss of speed and with an operating temperature of 35 degrees... Speed, stability, compliance with the declared characteristics. There's no such thing use WD WDS100T1R0A less than month |
