Hardware Encrypted SSD

Data security is very important for enterprise and industrial customer other than system performance and stability. To improve data security, Kogen can provide SSD with hardware protection function. We have two methods to ensure data security, first, our SSD has hardware encryption function follow Trusted Computing Group (TCG) Opal SSC standard. Encrypted data could not be easily accessed when SSD is lost. Second, when facing emergency situation that all data need to be wiped out immediately, our hardware purge or quick erase function is able to delete all data even the hidden area.

Currently most common method for data security are using software encryption. However, software encryption will occupy the resources of processor and RAM, and affect the system performance also data transfer speed will be slower. On the other hand, by using hardware encryption method, no RAM and processor will be occupied. Therefore, system performance and transfer speed can maintain high performance during encryption process.

TCG Opal SSC

Trusted Computing Group association establish the Opal Security Subsystem Class standard for SSD to follow the full structure and security specifications. Here are some of the features for TCG Opal SSC, firstly, before boot up into BIOS system, SSD will perform a pre-boot action and let shadow MBR to verify user access authority. After authority is been verified, then it will start loading BIOS, it is to avoid BOIS system from being altered.

Secondly, all SSD that follow TCG Opal standard have Self Encrypting Drive mechanism, controller will perform self-encryption for whole SSD. Thirdly, encryption key is stored in the controller, it can avoid security flaw of software encryption. Therefore, DMA attack or Cold Boot attack are not working.

Hardware Purge

For industrial info-secure and data protection other than TCG Opal SSC, there is another method call Hardware Purge or Quick Erase. There is a hardware push button to erase all data in the flash memory, and the SSD will return to default factory setting. Once hardware purge is activated, it will erase all data until it is done, if power has been removed during erase, after re-plug-in, it will continue to erase data and all data that has been deleted could not be rescue back.

Below is one example of mSATA memory module with quick erase function, data erase will start once Quick-Erase button has been pressed. mSATA is only quarter of the size of common 2.5” SSD, it is popular for industrial PC, portable storage, set-top box, etc. To know more about hardware encrypted SSD or other customised function, please contact us.

Performance comparison between Hard Disk Drive (HDD) and Solid State Drive (SSD)

HDD using one or more rigid rapidly rotating platters coated with magnetic material. Read and write data by an actuator arm with magnetic heads. Due to the actuator arm and magnetic head design, HDD will have mechanical limitations and problems. For example, HDD could not sustain strong impact and vibration, and motor will create noise during operating.

Solid State Drive
Solid State Drive

On the other hand, SSD use NAND Flash to store data, there are only controller, NAND Flash and other electronic components on PCB, no mechanical components that could create extra noise and not affected by vibration, this is the reason why SSD is very suitable for portable device and industrial product.

Other than that, HDD only has one actuator arm and magnetic head, therefore HDD only able to read data in one segment at a time. SSD uses controller as a core to control data read/write, so it could achieve multiple read write at the same time. Thus, SSD has much higher read/write performance than HDD. Below are the read write speed comparison.

Crystal Disk Mark

The average sequential read/write speed for HDD is less than 200MB/s, and average read/write speed for SSD is more than 500MB/s. For random file read/write, due to HDD only has one actuator arm and magnetic head, normal 4k read/write performance is only 0.5~1.5MB/s. However, SSD could perform multiple read/write at the same time, so the performance for random read/write is about 60~120 times more than HDD. Therefore, SSD is very suitable to work as a system drive to give higher performance speed, it is essential for computer open and software operating.

SSD Knowledge – NAND Flash Type

There are 3 types of NAND flash, SLC, MLC and TLC. SLC is first invented by Toshiba in 1987, but it has only small capacity and very expensive, usually use in thumb drive. After that MLC with higher capacity and lower cost was invented, but it is still expensive compare to HDD, so it is only used in enterprise level or high-end consumer. Finally, TLC came to the market, it has even higher capacity and an acceptable price for normal consumer. People start to use it in computer, mobile phone and other consumer product.

 

SLC: Single-Level Cell, store 1-bit data per cell

MLC: Multi-Level Cell, store 2-bit data per cell

TLC: Trinary-Level Cell or 3-bit MLC, store 3-bit data per cell

SLC MLC TLC NAND Flash Memory

How NAND flash works?

There is a silicon dioxide on each cell, it works as a cap of the cell, to prevent electron going in or coming out accidentally. When writing data, voltage will be increased to let electron pass through the silicon dioxide into the cell. To erase data, voltage will be increased again so electron can leave the cell by passing through silicon dioxide again.

As TLC can store 3bit data, it needs 8 different level of voltage to allow different number of electrons into the cell.

 

Performance: SLC > MLC > TLC

To read or write data, SLC is very simple, only 0 or 1, therefore SLC is the fastest. MLC has 4 different electron level, performance is slower than SLC. As for TLC, it has 8 different level, so it takes more time to determine the electron level. And sometimes there will be mistake when operating, therefore TLC need extra error correction to make sure the data is correct.

Life Endurance: SLC > MLC > TLC

SLC has up to 100,000 erase cycles, MLC has 5,000~10,000 erase cycles, but TLC has only less than 3,000 erase cycles.

It is due to TLC need 8 different voltage level and it can store more bits in single cell, the usage for electrons to pass through the silicon dioxide is much more frequent, it makes silicon dioxide layer wear out faster. Therefore, the life endurance for TLC is much shorter.

 

Capacity: SLC < MLC < TLC

TLC can store 3bit data in single cell, therefore compare SLC and TLC in the same chip size, TLC can store more data than SLC. It makes capacity of SSD getting closer to HDD.

Reliability: SLC > MLC > TLC

SLC only has 2 electron level, it is very easy to read and write. MLC and TLC have more than 2 electron level, especially for TLC, there are 8 different electron level, as the differences between each level are very small, error may occur when writing data. Therefore, SLC has the highest reliability compare to MLC and TLC.

 

Summary:

Items SLC MLC TLC
Performance High Medium Low
Life endurance ~100,000 5,000~10,000 ~3,000
Capacity ~512GB ~2TB ~4TB
Reliability High Medium Low
Cost High Medium Low

m.2 2280

m.2 2280 is the most popular internal mounted computer memory expansion card widely used in the market. Comparing with mSATA card, its size is much smaller therefore providing more flexibility in all kinds of solid-state-drive applications. For small products like ultrabook, slim notebook and tablet, m.2 2280 is the ideal selection. The former name of m.2 is “Next-Generation Form Factor” or NGFF.

Many users of SSDs get confuse with the terms form factor and interface bus. Therefore, it is important we highlight them here again. The name m.2 or mSATA referring to the product form factor. We also need to know what kind of interface being used at each SSD. SATA interface and PCIe interface are two different buses with SATA interface having a limit of bandwidth for SATA III at 6Gbps. For PCIe interface, depending on whether it is 2 lanes or 4 lanes, with 4 lanes going up to 30Gbps.

It can be used to replace mSATA and mini PCI Express interface card. By shrinking the form factor, m.2 2280 become smaller and faster than mSATA interface card. Comparing with mSATA which has a higher speed of SATA 3.0 6Gbps, m.2 offer even faster speed than this. The thickness of m.2 is only 3.5mm and it is more energy efficiency (lower power consumption and longer battery life).

m.2 2280 SSD card

m.2 2280 module card is rectangular in shape, with an edge connector on one side and has a width of 22mm and length of 80mm. It is installed into a mating connector provided by the host’s circuit board. The four digit m.2 form factor designation are: (first 2 digit state the device’s width in mm, and the second set of 2 number tell you how long it is, also in mm).

There are more than one kind of m.2 connector and different type of interface, leading to various sizes of m.2 card offering. You need to pay attention to the physical connector on the card. Each card has different cutouts at the bottom and expose different pins. Different connectors lead to various types of “module key”. Each key exposes a different set of interfaces to each card.

For m.2 2280, there are 2 types of module keys (Key B and Key M). Key B suitable for interfaces of PCIe x2, SATA, USB 2.0, USB 3.0, audio, PCM, IUM, SSIC and I2C and this key is commonly used in SATA and PCIe x2 SSDs. Key M is suitable for interfaces of PCIe x4 and SATA and widely used in PCIe x4 SSDs.

m.2 SSD "B" and "M" key

Newer motherboards are having the PCI Express bus interface, PCIe 2.0 x4 with a throughput ceiling higher than SATA 3.0’s. Newest technology is adopting PCIe 3.0 using NVMe (Non-Volatile Memory Express) for heavy and deep workload. It is important for you to make sure the motherboard you are using is able to support PCIe x4 when selecting the suitable m.2 card.

Different PCIe technology offering various speed running:

  • PCIe Gen 2 x2 lanes can run speed up to 1000MB/s
  • PCIe Gen 2 x4 lanes can run speed up to 2000MB/s
  • PCIe Gen 3 x4 lanes can run speed up to 4000MB/s

We just launched new m.2 2280 with 1TB storage capacity. This is from UD info, famously used in the market which require high reliability, good tracking record and well service support. By introducing this 1TB model, UD info can support small form-factor embedded system to implement higher capacity internal storage.

Features of this 1TB m.2 2280 SSD card:

  • support SATA III 6Gbps speed
  • using MLC Toshiba NAND memory chips
  • temperature support from 0 to +70degC
  • performance read up to 520MB/s and write up to 500MB/s

m.2 SATA SSDs use the same controller currently available at typical 2.5 SATA SSDs, whereas m.2 PCIe SSDs use a controller specifically designed to support PCIe protocol.

If the host system does not support PCIe protocol, when you insert the m.2 PCIe SSD inside the socket it will not work because the BIOS is not able to detect the card. Similarly, if you instal the m.2 SATA SSD into a socket which support m.2 PCIe SSD, your card will not able to use. Make sure your motherboard is able to support PCIe x4 speed, before you buy the PCIe x4 m.2 SSD, otherwise the card only function as PCIe x2 speed. All the m.2 SSDs are not hot-pluggable, it means you need to power off the system when you install or remove the m.2 SSDs.

Future interface is Non-Volatile Memory Express (NVMe) and its expected performance will be 4~6 times greater than existing SATA 3.0 standard and to be name as NVMe SSDs.
