Samsung's ultra-large-capacity SAS solid-state drive is put into mass production, up to 30.72 TB

Samsung said that this hard drive is developed for the next generation of enterprise storage systems. It uses Samsung's latest V-NAND technology, which combines 32 1TB NAND Flash memories; and each NAND Flash memory uses 16 V-NAND chip stacks. As a result, this hard drive can store 5,700 5GB high-definition movies, and its size is only 2.5 inches. In addition to the increase in capacity, the transmission performance of PM1643 has also been significantly improved, which is almost twice that of Samsung's previous generation of super-capacity SAS solid-state drives. Based on the 12Gb/s SAS interface, the random read speed and write speed of the PM1643 disk have reached 40000 IOPS and 50000 IOPS respectively, and the continuous read speed reached 2100MB/s and 1700 MB/s; the random read performance is the traditional 2.5-inch SATA 4 times of SSD, and continuous read performance is 3 times of the former. In order to achieve the above results, Samsung has made efforts in the design of...

How to buy a satisfactory SSD

The price of SSD is getting more and more cabbage, 500G only costs less than 60 dollars, and sometimes you can even buy 1T disks for 100 dollars. Double Eleven is coming soon. Many people may take the opportunity to buy an SSD. This big brother named Matt has compiled some suggestions for your reference. I hope everyone can buy satisfactory SSD. Tracking historical prices for interesting disks; If you buy it on Amazon, you can install a Camelizer plug-in on Chrome, and use this plug-in when browsing a certain SSD to see its historical price. If you are not using Amazon, you can use PCPartiPIcker, which can also provide similar functions. Note: We can ignore this feeling. After all, we basically buy it from cats and dogs; data is very precious (such as Dandan movies). Don’t buy those unknown brands. You can buy Dogfish for 50 yuan. Brands like KingDian and Vaseky that have never been heard before, but as long as you pay a little more, you can buy big brands like Toshiba, WD, and Cr...

From OpenChannelSSD to ZNS

No one has updated the Open-Channel SSD open source project on GitHub for a long time. It has been improved on the platform built by qemu, and bugs often appear. The requirements for the kernel version, qemu version, and system version are quite high. Although many papers have been published, I really feel that many of them are theoretical hypotheses and cannot really get the corresponding experimental results. Therefore, you must read the top meeting papers in terms of learning. After all, Ali’s internal technology is not public. of. To achieve cloud storage efficiency at the enterprise level today, a single SSD needs to meet many different workloads, and workloads can now be said to be ubiquitous. When using shared SSDs , interference between loads causes delays to rise and fall, and the worst delay increases dramatically. Only by ensuring stable service quality for every hard disk user can the service quality of the cloud environment be reflected. Traditional SSD handing the ...

Top 10 Solid State Drives (SSDs) of 2015

 AllTopTens.com editors prepared Top 10 Solid State Drives (SSD) list to help you choosing the best SSD in your budget and performance needs.   To improve performance significantly one of the easiest changes you can do with your PC is upgrading to an SSD. Solid state drives are way faster than conventional disk based Hard Drives. Let’s have a look at the top 10 SSDs of 2015 at a glance. We have made this list by various types of research, and we took in account SSD’s Sequential read speed, Sequential write speed, Random 4K read speed, Random 4K write speed, mixed read & write speed Affordability, Life span, power consumption, Windows boot time etc. System configuration While testing these Top Ten Solid State Drives we used standard SATA 3 interface and all the speeds were measured in this interface. Here is the machine we used. Intel Core i7 4790K at stock speed Asus Z97 Pro mobo Corsair Vengeance DDR3 16GB RAM (1866MHz) Windows 8.1 64Bit OS Corsair H100i Cooler Note: We u...

XPG Spectrix S40G RGB NVMe M.2 SSD Review (1TB)

On the test bench today is the XPG Spectrix S40G M.2 NVMe RGB SSD.  RGB has become very popular in the last few years and the fact that this SSDs RGB package can be configured with XPG’s own software package is a bonus, as well as its configuration being part and parcel with some motherboards. As a storage reviewer, however, we are always interested when companies break free of the current trend to add different hardware profiles to their products. XPG has done this with the Spectrix S40G by combining it with a not so commonplace Realtek RTS5762 8-channel NVME PCIe 3.0×4 controller. The XPG S40G is a PCIe 3.0 x4 M.2 SSD that is available in capacities ranging from 256GB to 2TB.  It uses the latest NVMe 1.3 protocol, comes with a 5-year limited warranty, and has performance specifications up to 3500MB/s read and 3000MB/s write with up to 290K read and 240K write IOPS at low 4k disk access. It has AES 256-bit encryption on board and has a listed product guarantee of 640TBW for t...

KIOXIA Announces First Shipments of Latest Generation PCIe 4.0 U.3 SSDs for Enterprise and Data Centers

KIOXIA America Inc. (formerly Toshiba Memory America, Inc.) is announcing that it has begun shipping their new lineup of CM6 (enterprise) and CD6 (data center) Series PCIe 4.0 NVMe solid-state drives.  The latest PCIe 4.0 specification was designed to double the performance of storage and server systems, enabling data transfer speeds of up to 16.0 Giga transfers per second (GT/s), or 2 gigabits per second (Gb/s) throughput per  PCIe lane, driving new performance levels for enterprise and data center applications. KIOXIA is an industry leader in developing PCIe and NVMe solid-state drives, and was the first to publicly demonstrate PCIe 4.0 SSDs, and is now the first to begin shipping these new next-generation SSDs.  Both the CM6 and CD6 Series comply with the latest NVMe specification, and include features such as NVMe-MI­™, shared stream writes, namespace granularity, and persistent event log.  Also, both the CM6 and CD6 Series conform to SSF-TA-1001 (U.3), allowing ...
