What is the expected product life / End-Of-Life?

Each flash die cycle lasts about 6-9 months for 3D TLC / 2.5 – 3 years for MLC or pSLC / 5 years for SLC. However, we can support the fixed BOM part for an additional 2 years at Flexxon’s liability. On top of that, we can extend the product life by replacing the flash and retaining the same controller (same series model) to achieve another 2 years of support. In total, the same series/ model part can last for at least 4 years. With the same controller, it will greatly reduce the compatibility issues with the customer’s host during the re-qualification.

Also, we can work with the customer to buffer flash and continue supporting fixed BOM ( same controller, same firmware version, same flash version ) for over 10 years. Flexxon does not EOL our solution as long as our customers still require it and have buffered the flash in place.
Expected Product Life

Are you able to support long term?

Our value and business strategy are to provide longevity assurance to support businesses in the IMA market especially yours for a longer period. We offer the following options:

  • Option 1: Upon part approval, we can support this part for over 1 year for 3D TLC / 2.5 – 3 years for MLC or pSLC / 5 years for SLC as we have many customers who are also using this mainstream product that you are going to sample. So, we can do some internal allocation to support this part for a long time when the demand forecast is provided.
  • Option 2: Another option is that we could work with you to buffer flash and continue to support fixed BOM (same controller, same firmware version, same flash version) for even over 10 years.

Flexxon never EOL our solutions as long as our customer still need the solutions and has provided the flash buffer in place. This is our memory strategy and our practice to prolong the product life cycle in such a fast technology change market to support all our customers.

We have a proven record of continually serving the IMA market. Most companies that we have been supporting had switched to us after receiving EOL notice from major players such as Kingston, Micron and they have been enjoying longevity assurance and tip-top support from us.

Why is the pricing so different compared to the competitors?

Pricing is always on the move for memory in general as you know. Our strategy is to offer a stable and low average price as opposed to the “price of the day” approach of some of our competitors. Our long-term customers appreciate this approach as they can plan more effectively. We are always competitive on an apple to apple comparison. If you find our pricing to be way off it usually means that we are not quoting on the same specs. The bottom line is that we will compete aggressively and, once we are engaged, we will provide stable pricing for the life of your program.

What’s OP (Over-Provisioning)?

An SSD controller is responsible for the massive task of managing all data traffic and storage for the drive. NAND technology’s intrinsic complexities require a lot of extra work behind the scenes. A data write is not as simple as placing data into an empty memory bank. Each NAND cell has a limited lifespan – it can only endure a specific number of data reads/writes. An additional layer of complexity is added by the fact that overwriting old data on NAND requires an erase of the entire NAND block (this same block may contain other data that is still valid). As a result, the controller is constantly moving data around to ensure that the cells wear evenly and to pre-emptively prepare “free blocks” to use for future data writes.

All of this management work requires the SSD to have a kind of “swap space” available to use as temporary storage while the controller goes about its business. The controller will use any available free space for this, but free space becomes a premium commodity as we fill our drives with data. OP is a way to set aside a minimum amount of free space, inaccessible to the user or the OS, which the SSD controller can utilize as a kind of “work bench.”

Why use Over-Provisioning?

OP has a direct effect on SSD performance under sustained workloads and as the drive is filled with data. Guaranteeing free space to accomplish the NAND management tasks discussed above (Garbage Collection, Wear-Levelling, Bad Block Management) means the SSD does not have to waste time preparing space on demand, a process that requires additional time as data is copied, erased, and recopied. An added benefit is that OP makes all of the SSD maintenance procedures more efficient, reducing the WAF by ensuring there’s room to work.

Consider this scenario: You are a chef with very limited counter space (say one arm’s length across and half and arm’s length deep). Preparing a 5-course meal in such a limited area would mean you have to waste a lot of time moving things around or putting them away to make room for other tasks. Now, imagine you quadruple your work space. You can leave everything you need at hand, reduce repeating steps (like getting the salt from the pantry and putting it back away), and increase your working speed. The same goes for SSDs. Give them more room to work, and they can do it more quickly and efficiently, reducing WAF and increasing performance at the same time.

Full Capacity SSD vs. Extra Over-Provisioning

For SSD with full capacity (512GB, 1TB) and SSD with extra OP (480GB, 960GB), using the same capacity NAND flash.

The following picture illustrates the SSD with inherent OP and additional OP. All SSD has inherent OP, but for 480GB/960GB SSD, it has additional OP with improved endurance and reliability compared to Full Capacity SSD.

fullssd-vs-extra

The following illustration shows higher OP increases the TBW. Therefore, for industrial application, especially with the 3D NAND flash, we highly recommend to use SSD with extra OP.

Nevertheless, we are still able to support full capacity size, if the customer insist.

What is the operating system supported by WORM card?

Windows, Android and Linux are the operating system supported by WORM card.

Could WORM Card support multiple partitions?

Yes. FLEXXON WORM Card could support 2 partitions upon request with the condition below:

  • Partition 1: Standard Partition. Read/ Write/ Delete/ modify/ overwritten/ parallel writing is possible. Also, it could support another file system such as exFAT/ ext3/ ext4
  • Partition 2: WORM Partition. User could not modify/ delete/ overwritten/ format the data. Only support FAT32 file system.

Can I format WORM card to other file system such as NTFS, ext3, ext4 etc?

No, user have no authority to format it to other file system.

Does WORM Card support to pre-format to other file system such as NTFS, ext3, ext4.

For this current version it only supports FAT32 file system and WORM card is done in the firmware level.
Please refer to question 4 if you require other file system.

What is the block allocation size of WORM Card?

The block allocation size of WORM Card is 32KB.

Is there a possibility (even low) to manipulate written data on the WORM Card and how?

After data is written, there is no way to change, modify, delete and format.

Can we use WORM Card again after writing process, formatted it and use in the future?

You can write data until full capacity. After data is written, it could not be change, modify, delete and format.

Is that any specific writing pattern when I used WORM Card?

WORM card does not support parallel writing such as real time recording. For writing files, it must follow “one by one” sequential writing. That is, a file writing must be finished completely first before starting another one.

Does WORM Card support AES Encryption?

Flexxon WORM card uses Flexxon proprietary crypto algorithm DSD which perform data scrambling and descrambling. Flexxon WORM Card perform read and write through scramble algorithms.

Why am I able to delete / rename/ overwritten files when using WORM Card?
