IOPS, Throuhput, Latency: Understanding SSD, HDD Storage Performance Benchmarks

Several weeks ago, we published an article on some of what we consider the best benchmarking applications for testing HDD and SSD performance. After the article was published, we realized that while most of us familiar with storage benchmarking can easily discern what each of the results mean, those not familiar with storage testing have little to no idea what stuff like MB/s, IOPS, or ms actually means and more importantly what the numbers tell us in the grand scheme of storage performance.

As such, today we’ll be covering what most of the storage industry would consider as the trifecta of storage performance: IOPS, Throughput, and [...]

CES 2017: Phison Demos E8 Entry Level PCIe NVMe SSD Controller

With the NAND shortage in full effect at CES this year, SSDs didn’t really make much of an appearance at the show. However, we did get a chance to stop by controller vendor, Phison, who had a new entry level PCIe NVMe controller to show.

The new controller is the Phison E8 which is going to be the low cost brother to the Phison E7. The new controller will come in two variants: the PS5008-E8 or PS5008-E8T.

The Phison PS5008-E8 will be a PCIe Gen 3 x2 controller featuring performance up to 1.6GB/s sequential reads and 1.3GB/s sequential writes. Random read/write performance will top out at 240K/220K IOPS respectively. It’ll also feature support [...]

Intel Optane DC P4800X 3D XPoint SSD Spec Sheet Leaked

Intel’s collaboration with Micron to develop 3D XPoint storage has been a long time in the works and for the first time, we’re getting a concrete idea of how Intel’s upcoming Optane 3D XPoint-based enterprise SSDs will perform.

According to a recently leaked spec sheet by Chinese technology website, Techbang, the upcoming Intel Optane DC P4800X a very admirable drive. Coming in the HHHL form factor, the Optane DC P4800X features up to 375TB of storage and features the PCIe NVMe interface which allows for sequential read/write speed of up to 2,400/2,000MB/s, and 4K random performance up to 550,000/550,000 IOPS respectively.

What’s really [...]

TSMC 7nm Process Ready to Go, Samsung 7nm Still in Development

At the International Solid State Circuit Conference (ISSCC), both TSMC and Samsung had working chips samples built on their respective 7nm nodes. However, the two companies gave very different outlooks on their readiness.

According to the presentation offered by TSMC, they described the condition of their 7nm node as “healthy”. Samsung on the other hand, had a bit less confidence in its production method, showcasing a development chip that suggests 7nm chips may not be ready for at least a few more years.

The reason behind the contradicting prospects is due to the different manufacturing techniques. Because TSMC will likely be producing the Apple A11 [...]

Intel Launching Optane SSD in 1Q2017, 3D XPoint DIMM Now Sampling

Intel’s 3D XPoint has been long touted as a revolutionary new non-volatile memory technology ever since Intel announced it back in 2015. Unlike traditional NAND, 3D XPoint uses a mesh of storage cells that can greatly improve access times compared to conventional storage. According to Intel’s internal testing, Optane SSDs can reach speeds up to 10x faster than current generation SSDs. However since its launch, 3D XPoint has been more talk than anything else with both Intel and development partner, Micron, doing little more than talking about the performance, applications, and missing potential launch dates.

That said, this time it appears that Intel may [...]

5 Best Free Tools for Testing SSD, HDD Storage Performance

With the recent increase in popularity of SSDs, storage performance has returned to the spotlight as SSDs have highlighted the effects of having a slow storage sub-system. For those who own a SSD or have experienced what it’s like to use one, you’ll know that slow storage can easily drag down an entire system even if your system features the latest and greatest Intel Core i7 processor with hundreds of gigabytes of RAM.

As such, testing for storage performance has become more crucial than ever, so to help you test the performance of your drive, here’s five of the best free storage testing utilities.

Samsung 850 Pro 4TB Delayed Due to NAND Shortage

At CES 2017, Samsung had originally planned to launch the Samsung 850 Pro 4TB which would’ve made the Samsung 850 Pro not only the fastest consumer SATA SSD on the market, but also the highest capacity as well. However, after scouring the CES show floor for SSD related announcements and not seeing the drive on display at CES 2017, Tom’s Hardware reached out to Samsung’s PR agency for some information where they received the following:

“As a result of the worldwide NAND shortage, Samsung is focused on allocating NAND to products where we see the greatest demand. We will let you know when further updates on the 850 PRO 4TB are available.”

As many [...]

CES 2017: Kingston Unveils 2TB DataTraveler Flash Drive, A400 Entry Level SSD

During CES 2017, we stopped by the Kingston suite who had several new memory products to showcase including a brand new world’s highest capacity flash drive and an upcoming value SSD.

 

Kingston DataTraveler Ultimate GT

When Kingston launched the DataTraveler Ultimate back at CES 2013, it was touted as the highest capacity flash drive ever made, touting up to 1TB of storage in a very compact form factor. With the Kingston DataTraveler Ultimate GT, Kingston beats that by doubling the capacity to 2TB while still keeping the drive in the same compact form factor.

Performance unfortunately hasn’t changed a whole lot [...]

CES 2017: Plextor Unveils M8Pe NVMe SSD, EX1 External SSD, 2017 SSD Roadmap, Wireless CD/DVD Drive

For the most part, SSD introductions were few and far in-between at CES this year, but SSD maker Plextor made a splash in CES with several new product announcements.

 

Plextor M8Se PCIe SSD

The Plextor M8Se series of SSDs looks to bring the best cost to performance ratio to the high-end consumer market. Powered by Toshiba 15nm TLC along with the Marvell 88SS1093, the M8Se supports the PCIe Gen 3 x4 interface and the latest NVMe standard, allowing the top capacity Plextor M8Se model can reach up to 2.45GB/s in sequential reads and 1GB in sequential writes. 4K random performance is blazing fast too, rated at 210K IOPS reads and 175K [...]

CES 2017: Toshiba Puts 512GB NVMe SSD into Tiny 16x20mm BGA Form Factor

For CES 2017, Toshiba showed off its new BG series SSD in the M.2 1620 BGA and M.2 2230 form factor for ultraportables and mobile devices.

Powered by Toshiba BiCS 3D TLC NAND along with a Toshiba controller, the Toshiba BG series demonstrates the capabilities of Toshiba’s 3D TLC, scaling up to capacities of 512GB in a form factor as small as 16x20mm. In order to achieve this, Toshiba integrated the controller and the NAND into a single package, and as the drive utilizes NVMe’s Host Memory Buffer (HMB) feature which utilizes system DRAM to act as a buffer, DRAM is not required.

The Toshiba BG M.2 1620 SSDs are designed to be integrated into [...]
