With the explosion of digital content, people need bigger and more robust solutions to help access and preserve it all. Western Digital today is introducing a portable HDD expansion across its WD, WD_BLACK and SanDisk Professional product lineups, boasting the world's highest storage capacity in a 2.5" portable HDD. The WD My Passport portable HDD line, WD_BLACK P10 Game Drive and SanDisk Professional G-DRIVE ArmorATD will all now be available in 6 TB capacities.

"Expanding our portfolio with the world's first 2.5" 6 TB portable hard drive is an incredible technological achievement, and it enables us to continue pushing the boundaries of what's possible," said Nitin Kachhwaha, Director of Product Management at Western Digital. "Offering up to 6 TB in such a small form factor and accessible price point gives everyone - from students, gamers, professional videographers, and more—greater flexibility to create and keep even more of their essential content in one portable drive."

Western Digital Corp. ("Western Digital" or "the Company") today provided an update on its previously announced plan to separate into two independent, publicly traded companies. On track for the second half of calendar year 2024, significant progress towards the completion of the separation is underway with key transactional projects including global legal entity establishment, customer and supplier contract transfers, final stage preparation for government filings, and initial executive leadership appointments for both HDD and Flash companies post-separation.

Announced on October 30, 2023, Western Digital plans to separate its HDD and Flash businesses, creating two independent, public companies with market-specific, strategic focus. The company's separation will better position each franchise to execute innovative technology and product development, capitalize on unique growth opportunities, extend respective market leadership positions, and operate more efficiently with distinct capital structures.

The University of Shanghai for Science and Technology (USST), Peking University and the Shanghai Institute of Optics and Fine Mechanics (SIOM) are collaborating on new Optical Data Storage (ODS) technologies—a recently published paper reveals that scientists are attempting to create 3D nanoscale optical disk memory that breaks into petabit capacities. Society (as a whole) has an ever-growing data demand—this requires the development of improved high-capacity storage technologies—the R&D teams believe that ODS presents a viable alternative route to traditional present day solutions: "data centers based on major storage technologies such as semiconductor flash devices and hard disk drives have high energy burdens, high operation costs and short lifespans."

The proposed ODS format could be a "promising solution for cost-effective long-term archival data storage." The researchers note that current (e.g Blu-ray) and previous generation ODS technologies have been: "limited by low capacities and the challenge of increasing areal density." In order to get ODS up to petabit capacity levels, several innovations are required—the Nature.com abstract stated: "extending the planar recording architecture to three dimensions with hundreds of layers, meanwhile breaking the optical diffraction limit barrier of the recorded spots. We develop an optical recording medium based on a photoresist film doped with aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This film is highly transparent and uniform, and the aggregation-induced emission phenomenon provides the storage mechanism. It can also be inhibited by another deactivating beam, resulting in a recording spot with a super-resolution scale." The novel optical storage medium relies on dye-doped photoresist (DDPR) with aggregation-induced emission luminogens (AIE-DDPR)—a 515 nm femtosecond Gaussian laser beam takes care of optical writing tasks, while a doughnut-shaped 639 nm continuous wave laser beam is tasked with retrieval. A 480 nm pulsed laser and a 592 nm continuous wave laser work in tandem to read data.

AMD's 3D V-Cache technology utilizes blocks of SRAM stacked on top of the CPU logic die, where CPU cores reside, and allows the processor to access massive pools of cache for applications. However, using this extra level 3 (L3) cache as a RAM disk appears possible, where the L3 SRAM behaves similarly to a storage drive. A big disclaimer here is that this is only possible by exposing the L3 to the CrystalDiskMark benchmark, and no real-world applications can do it in a way that CrystalDiskMark. According to X/Twitter user Nemez (@GPUsAreMagic), the steps to replicate this procedure are: Obtaining an AMD Ryzen CPU with 3D V-Cache, installing OSFMount and creating a FAT32 formatted RAM disk, and running CrystalDiskMark, with values set to values to SEQ 256 KB, Queue Depth 1, Threads 16, and data fill to 0s instead of random.

The results of this experiment? Well, they appear to be rather stunning as the nature of L3 SRAM is that the memory is tiny but very fast and accessible to the CPU, so it can help load data locally before going to the system RAM. With AMD Ryzen 7 5800X3D, the speeds of this RAM disk are over 182 GB/s for reading and over 175 GB/s for writing. In another test, shared by Albert Thomas (@ultrawide219), we managed to see RAM disk based on AMD Ryzen 7800X3D V-Cache, which scores a little less with over 178 GB/s read and over 163 GB/s write speeds. Again, CrystalDiskMark only performed these tests on small allocations varying between 16 MiB and 32 MiB, so no real-world workloads are yet able to utilize this.

Crucial T700, the company's flagship M.2 NVMe Gen 5 SSD, runs hot—like every other drive based on the Phison E26-series controller (such as the Corsair MP700). ComputerBase.de discovered what the drive does without some sort of cooling. The E26 controller has a Tjmax value of around 86°C, and what happens when it's reached depends on the drive in question. The Corsair MP700 can turn itself off to protect the controller—something that will definitely cause your machine to hang with a BSOD.

The Crucial T700, on the other hand, aggressively throttles down the controller in an attempt to lower temperatures. While the drive won't stop (and your machine won't hang), its performance drops to hard drive levels, with CrystalDiskMark (CDM) measurements pointing to around 101 MB/s (of course, with much lower access times than a HDD). Both Crucial and Corsair offer the drive with large heatsinks, and recommend users to use them. This should severely limit the adoption of Gen 5 NVMe SSDs among notebooks, where the notebook chassis has room for only bare drives. However, some OEMs specializing in larger high-end gaming notebooks and desktop-replacement workstations, can find ways to connect the drives to the notebook's main cooling system using flattened heatpipes. You can catch ComputerBase's review of the MP700 in the source link below.

With only three major players left in the hard disk drive market-Seagate, Toshiba and WDC-the shipment of hard drives ought to be fairly stable, but demand is down across all manufacturers by anything from close to 30 percent to around 40 percent in the case of Toshiba. According to data from Trendfocus that was posted by Storage Newsletter, demand is down across all market segments or at best case flat compared to last year. Nearline enterprise drives remained flat at around 19 million units compared to last year, but performance enterprise storage is down to around 2.5 million units for the last quarter.

On the desktop and consumer electronics side of things, things are even more dire, with both 3.5-inch and 2.5-inch drive shipments dropping by 30 and 40 percent respectively. Around 13 million 3.5-inch hard drives and 11 million 2.5-inch drives were still shipped in Q2, but with lower demand for computers and more and more computers moving to SSDs, hard drives have been relegated to backup duties when it comes to most consumer purchases. Seagate was the company least affected by the drop in demand, but is still seeing close to a 30 percent drop in demand, with WDC second at over 30 percent and Toshiba, as mentioned, by maybe as much as 40 percent, which doesn't bode well for the company, as it's the smallest manufacturer of hard drives.

According to the latest report by Windows Latest, Microsoft's Windows 10 2004 May update will bring a much-needed disk performance update. The underlying reason behind this improvement is the terrible performance of the Windows Search indexer, which in previous versions of Windows 10 had high disk usage and resulted in a slowdown of the system. However, Microsoft decided to improve that and found a way to optimize its performance. This improvement will be of much need to everyone who owns and runs Windows 10 on a Hard Drive.

In Windows 10 update 1909, Microsoft has decided to separate Cortana from the Windows Search and thus brought disk usage a bit lower. However, Microsoft's engineers have been fine-tuning the Search Indexer, and now the performance is significantly better while having a lot less disk usage. Previously, the Search Indexer was very aggressive and spared no resources for its process, so this is a welcome addition. This improvement will leave disk usage capacity to other processes and will result in a noticeably snappier system, which Hard Drive users will appreciate the most.

One nifty new feature currently being deployed to Windows 10 Fast Ring users is the ability to see exactly how much power a given process is consuming in your system's hardware (CPU, GPU & Disk). The new feature, which appears as two additional Task Manager tabs, showcases the instantaneous power usage of a given process, but also features a trend calculator that covers a two-minute interval. This should be pretty handy, if the measurement process is close enough to the real power consumption. This could even be used as another flag for cryptomining malware or scripts in a given webpage.
