Western Digital launches SSD and SN740 modules for professionals

In addition to bringing news to the data center market, Western Digital announced during Monday’s conference (9) new hard drives aimed at power users. While focusing on content creators with the PRO-BLADE ecosystem, the SN740 PC is dedicated to hybrid work, and ultrabooks are expected to be released in the coming months.


Under the brand SanDisk Professional, newly launched to meet the needs of the “consumer” audience, the manufacturer announced the PRO-BLADE ecosystem for SSDs. The novelty seeks to make life easier for content creators who demand large amounts of storage, usually need to change SD cards for cameras and other devices frequently, or use large equipment to access more memory.

The kit mainly consists of three parts, starting with the PRO-BLADE SSD Mag, a unit equipped with an NVMe PCIe 3.0 x4 SSD. The solution features an aluminum capsule, for resistance and better heat dissipation, and a custom fit to ensure maximum component speed, with 3 GB/s read and 2.6 GB/s write.

Other interesting points of this connection are its “hot-swappable” nature, which allows the unit to be removed without restarting the computer, and the fact that it is not a proprietary technology, and can be adopted by NAS manufacturers, as small local servers dedicated to storing data.

Western Digital ensures that SSD Mag can withstand 3m drops, approximately 2t pressure, and more than 2,000 dock/undock cycles.

The modules can then be connected to the other two parts of the ecosystem, the PRO-BLADE TRANSPORT and the PRO-BLADE STATION. The first, aimed at portability, has a dedicated heat dissipation to maintain high speeds, an LED to indicate disk usage time, as well as an aluminum chassis, using a USB-C 3.2 Gen 2×2 port to connect to a PC and deliver faster speeds. to 2 GB / sec.

STATION focuses on high transfer rates, supporting up to 4 cups of SSD running in the JBOD protocol, making it work as a single volume.

The device has slots for ventilation, slots for mounting on dedicated bases, LEDs to show use and two Thunderbolt 3 ports for connecting to a computer, allowing drives to reach their full speed.

The manufacturer highlights that this ecosystem is more practical than similar traditional solutions, including SanDisk Professional’s G-DRIVE and G-RAID, using the work of producer Lucas Gilman as an example.

To reach 124 TB, Gilman needs a group that weighs about 20 kg. With the PRO-BLADE line, the content creator will only be able to reach 80 TB, but carry the equivalent of 3 kg.

Together with the PRO-BLADE family, the manufacturer has also unveiled the new Extreme Pro family of UHS-I SD and MicroSD cards, equipped with optimized algorithms to deliver transfer rates of up to 200MB/s – twice the 100MB/s offered by the UHS-I protocol. I, and 15% faster than the 170MB/s that older models achieved in the range.

To reach these speeds, users must use the company’s new PRO-READER, which is equipped with the necessary extensions. In other devices and readers, the cards provide a standard speed of 100 MB / s.

SN740 PC for the future of hybrid work

Aimed at manufacturers of ultrabooks and other devices, the Western Digital PC SN740 has been designed with the reality of remote and hybrid work in mind.

Together with the company’s new BiCS5 memories, TLC-standard and operating with the PCIe 4.0 bus, the launch promises read rates of up to 5150 MB / s, which is 50% faster than the SN730, which reached a speed of 3400 MB / s.

Available in M.2 format in 2230, 2242 and 2280 sizes, the SN740 promises to reduce footprint, fetch memories on only one side of the unit, and reduce consumption by 45% compared to the previous generation by forgoing the use of DRAM.

Additionally, keeping in mind the security risks posed by hybrid operation, the component has optional protection features such as ATA password and encryption with TCG Opal 2.01.

Microsoft was present during the presentation of the novelty and it should be one of the manufacturers to adopt the SN740 in future versions of the Surface line.

Price and availability

The SanDisk Professional PRO-BLADE SSD Mag and PRO-BLADE TRANSPORT debuted in June, while the PRO-BLADE Station is due to arrive later this year, but no date has been set.

The Mag SSD will sell in capacities ranging from 1TB to 4TB, with prices ranging from $179.99 (~$925) to $599.99 (~$3,080), while the transfer is sold separately for $69.99 (~$69.99). US dollars). Up to 4TB of storage is included for $659.99 (about 3,390 R$).

The new Extreme Pro and PRO-READER models also appeared in June, priced as low as $279.99 (~$1440) for the SD format and up to $329.99 (~$1695) for the MicroSD versions. , while it costs the reader US dollars. 49.99 (~260 BRL).

Finally, the SSD PC SN740 has already begun to be produced and shipped to laptop manufacturers, and it is assumed that it will debut in models at the end of 2022.
