The 1TB Samsung eUFS Chip

The new 1TB Samsung eUFS chip is the world’s first embedded Universal Flash Storage 2.1 (eUFS 2.1) device to break the terabyte threshold. It is powered by their fifth-generation V-NAND memory, and a new proprietary controller.

The 1TB Samsung  eUFS chip offers twice the storage capacity of its predecessor in the same package size (11.5 mm x 13.0 mm), by stacking 16 layers of Samsung’s 512 Gb V-NAND flash memory.

The larger storage capacity is important as 4K videos become more popular, and smartphone cameras increase in resolution. The recently-launched HONOR View20, for example, sports a 48 MP camera whose photos come in at about 15 MB in size!

The 1TB storage capacity will allow you to record approximately 43 hours of 4K videos, or 67,000 photos from a 48 MP camera. Your entire life can literally be stored in this one chip!

Higher Performance

In addition to doubling single-chip storage capacity, the 1TB Samsung eUFS chip is significantly faster. With a read speed of up to 1 GB/s, it is about twice as fast as solid state drives used in high-end laptops!

Samsung also improved its random read and write speeds by 38% and 25% respectively over its 512 GB predecessor. This means it is approximately 500X faster than a typical microSD card!

Such high performance is important for flagship smartphones, because it allows them to support high-speed photography and video recording at 960 frames per second or faster!

 

1TB Samsung eUFS Availability

Samsung has already begun mass-producing the 1TB Samsung eUFS chip. We should see devices using this new storage chip this year.

In fact, they anticipate strong demand for the chip in 2019, and plan to expand the production of their 5th generation 512 Gb V-NAND memory at their Pyeongtaek plant in the first half of 2019, to meet this demand.

HUAWEI P20 Pro Recalled After Shipping With Real ROM!

Excited about the HUAWEI P20 Pro? You may have to wait a while longer! Sources tell us that HUAWEI recalled over 60,000 of their P20 Pro smartphones after they shipped with real ROM!

 

The HUAWEI P20 Pro Recall

The HUAWEI P20 Pro is 6.1″ smartphone with a Full HD+ OLED display, and is powered by the octa-core HiSilicon Kirin 970, with 6 GB of LPDDR4 memory128 GB of flash storage, and a 4,000 mAh battery.

However, a large number of the P20 Pro had to be recalled after HUAWEI discovered that they shipped with real ROM, instead of regular flash memory. In a way, these 60,000 HUAWEI P20 Pro smartphones made history by being the first smartphones to actually shipped with real ROM chips!

HUAWEI traced the fault to a manager at their flash memory supplier who took their order for ROM chips too literally. They shipped actual ROM chips to them, instead of eMMC / UFS NAND chips that smartphones use.

The unnamed manager defended his action, pointing out that even HUAWEI’s website clearly states that the P20 Pro comes with ROM, and not regular NAND flash memory chips.

We checked, and true enough, the HUAWEI website officially lists that the HUAWEI P20 Pro comes with 128 GB ROM.

The moral of this story – STOP CALLING FLASH MEMORY ROM!!!

 

ROM versus Flash

ROM is short for Read Only Memory. The most basic ROM chip has its data programmed during its manufacture, and cannot be deleted or edited. ROM chips are useful because they are non-volatile – they retain their data even when power is cut.

[adrotate group=”2″]

Newer ROM chips can be reprogrammed, but only slowly and with some difficulty – the entire chip must be erased before being overwritten. They are mostly used to store computer firmware that are not changed very often.

Flash memory, which is used as smartphone storage and in computer solid state drives, is also non-volatile. But their data can be replaced on a block-by-block basis, allowing them to be used as storage devices.

In short – smartphones do NOT use ROM chips for storage. They use flash memory chips!

ADATA XPG SX8000 Gaming SSD Launched

Taipei, 29 September 2016 – ADATA Technology, a leading manufacturer of high performance DRAM modules and NAND Flash products, today launched the XPG SX8000 SSD, which uses an M.2 form factor loaded with 3D MLC NAND Flash and an SMI 2260controller.

The SX8000 meets NVMe 1.2 specifications and connects directly to motherboards via PCI Express 3.0 x4 (PCIe 3×4) to deliver 2.4GB/s read and 1GB/s write, with 100K/140K IOPS. The SX8000 arrives in diverse capacities (128GB, 256GB, 512GB, and 1TB), ensuring a new generation of SSD performance is available to more users.

A slightly faster version fitted with an attractive XPG heatsink will release by the end of October, promising an aesthetic bonus for case modding enthusiasts.

 

ADATA XPG SX8000

Compact M.2 PCI 3×4 shatters speed barriers

The XPG SX8000 connects to desktop and notebook PCs via low profile M.2 2280 and channels data through PCI Express 3.0 x4 (four lane). The low latency and big bandwidth of PCIe enable up to 2.4GB/s read and 1GB/s write – four times the read and twice the write performance of average SATA 6Gb/s SSDs. Random 4K IOPS figures are 100K read and 140K write, also significantly more than SATA-based drives.

The SX8000 features full NVMe 1.2 compatibility, powering a large performance boost that means users notice gains in real world scenarios, especially loading times within games that require heavy asset streaming and in professional applications such as graphics and audio rendering.

Flexible and durable 3D NAND

The XPG SX8000 represents a new era not just in performance, but in its very architecture. It uses reliable 3D MLC NAND Flash, allowing ADATA to produce versions in capacities from 128GB to 1TB. With 3D NAND, reliability, performance, and efficiency all get a boost as more storage is fitted onto a smaller form factor without increasing power demands. The SX8000 features a 2 million hour MTBF (mean time between failures) rating, or 25% longer than 2D NAND SSD (which average 1.5 million hours).

Range of data-enhancing features

ADATA firmware design takes utmost data performance and integrity into consideration with every SSD. Intelligent SLC Caching allows the drive to operate in pseudo single-level cell mode for speed boosts when extreme data loads are encountered. It can also leverage system RAM to increase performance via DRAM Cache Buffer, helping maintain consistent throughput even during the most intense tasks.

LDPC ECC (low density parity check error correction) prevents data corruption and promotes integrity, while Data Shaping evenly distributes task loads across NAND Flash cells. The SX8000 is therefore a pioneer in performance that offers a complete package of reliability-augmenting features. It is backed by a 5-year warranty.

Stacker NAND Technology TRIPLES Flash Capacity

Terrarium Labs announces the successful certification of their Stacker NAND technology which triples the capacity of existing flash memory technologies. As an IP R&D company based in the China West Technology Park, Terrarium Labs has been focused on developing compression technology to massively expand flash storage capacity.

 

Stacker NAND Technology

Unlike existing MLC and TLC NAND technologies, Stacker NAND works independently of NAND process technologies. In fact, it is applied to existing NAND flash technologies to triple their capacities.

The Stacker NAND technology uses two different compression methods to deliver TRIPLE the capacity of any existing NAND flash storage technology.

The first is a lossless data compression algorithm that compresses data before they are written to the NAND flash memory. Depending on the file type, this can almost double the amount of data that can be stored in a particular flash chip.

To further increase the storage capacity to 3X, they add a lossy compression technology which applies filters that reduces the randomness of the data. This allows the earlier lossless compression technology to be even more effective.

At the moment, Terrarium says 3X more storage is a good compromise between additional storage and loss of data. But if necessary, they can scale it up to 5X or even 6X.

 

Only For Photos & Videos

As you can tell, the Stacker NAND technology cannot be used for regular data. It is designed to be used only for photos and videos. Terrarium Labs was very explicit that their compression technology will change some data in return for much small file sizes when compressed. However, they see this as a small price to pay for much larger storage capacities at the same price.

According to Terrarium Labs, a 256 Gbit Stacker NAND module paired with a regular 256 Gbit NAND module will double the effective capacity for very little cost – 768 Gbit of lossy storage + 256 Gbit of lossless storage.

Below is a prototype M.2 SSD module they created out of one regular 256 Gbit NAND module and two 256 Gbit Stacker NAND modules for 2.33X the effective storage capacity – 1,792 Gbits of storage, instead of just 768 Gbits. That’s just over 1,000 Gbits of extra storage!

Although Terrarium Labs admits that their lossy compression algorithm will reduce image quality, they say that at 3X, this is minimal and will only be obvious if the pictures or videos are examined very closely. They also pointed out that some of the filters used will actually reduce noise, which enhances picture and video quality.

Photo Comparison

Obviously, we found that hard to believe, so they invited us to send them some photo samples. We sent them a dozen photo samples from the ASUS ZenPad 7.0 and the recently-reviewed honor 5X smartphone. Take a look at the four comparisons of their lossy compression filters at work.

They are correct that the difference is subtle and only apparent up close. There is some loss of detail, but also less noise. But would you accept such changes?

 

Adaptable

[adrotate banner=”4″]

Terrarium partners can pair the Terrarium Stacker processor with any number of NAND modules, and choose either lossless or lossy compression, or both.

Terrarium is also offering the compression software to partners who prefer to do without the processor, but it may sap up to 30% of a quad-core processor’s cycles.

They claim they’re currently in talks with the top smartphone manufacturers from the United States, Korea and China to introduce the Stacker processor and/or software into the next-generation smartphones.

 

Fun Fact

Tech old-timers will remember Stacker, the disk compression utility for MS-DOS. It not only doubled the capacity of our puny 42 MB hard disk drives, it also sped up reads and writes by compressing data before they were written to the abysmally-slow hard disk drives of the day. However, Stac Electronics, the company that developed Stacker soon crumbled after Microsoft introduced their free DoubleSpace disk compression software.

Little known to many, Stac Electronics spun off a chip making company called Hifn, which makes encryption and compression processors. Some of Hifn’s key engineers are those who helped form Terrarium Labs. That’s why they named their first product – Stacker.

 

Feed Us!

If you don’t support us, who will? The last we checked, money still does not fall down from the heavens. Too bad we can’t live on sunshine and rainfall. We are not plants. In fact, we don’t even like eating our vegetables! We LOVE meat. So if you like our work, help us buy some meat… or send us some meat! Preferably with a nice bottle of red to go with it. 😀
