powersafe SATA 固态硬盘

為了在關鍵任務應用中實現更優異的保護,Swissbit 開發了「powersafe」功能,它具有更高的 PLP 保護能力,在資料從主機傳輸到控制器(動態資料)和從 DRAM 傳輸到 NAND(快取資料)時都能保護資料。採用此項新功能的高可靠性長生命週期 SSD 能實現業界領先的 PLP 保護能力。
針對某些 SSD 產品系列,Swissbit 會將「powersafe」作為選購功能提供,並會在產品名稱中加註尾碼 P。首先推出的是 2.5 吋和 M.2 尺寸規格的 X-75 產品系列,該系列已可提供增強 PLP 保護選項。該系列採用了 SATA III 介面的 3D NAND TLC SSD。其支援工業級寬溫範圍,並提供極高的耐用性和可靠性,容量範圍介於 30GB 到 1,920 GB。

Data care management
Data Care Management

Various effects like data retention, read disturb limits, or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.

Life Time Monitoring (LTM)
Life time monitoring (LTM)

The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows prediction of imminent failure, avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor-specific commands to retrieve the Flash product information.

Power Fail Protection & Recovery
Power fail protection

Intelligent Power Fail Protection and Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.

Power fail protection PLUS

Products with the Swissbit powersafe feature use reliable tantalum capacitors to store energy so that in case of a sudden power fail the charge will be used to harden the cache content into the NAND flash.

Read-only optimized
Read-only optimized

In many industrial applications the data is written to the NAND Flash once and is only read afterwards. For such cases, the firmware can be optimized in order to guarantee the highest possible data retention and less read disturb.

Secure erase
Secure erase (Sanitize / Purge) / Fast erase

This feature uses an uninterruptable sequence of data erase commands. Even a power off can’t stop the process, which will continue upon restoration of power. The optional enhanced feature allows the customer to sanitize the data according to different standards like DoD, NSA, IREC, etc. The purge algorithm can be started by a software command or through a hardware pin.

Shock & Vibration
Shock and vibration

Robustness is one of our key specification targets. The design, assembly and use of selected materials guarantee an extremely solid design which has been validated by extensive testing.

Temperature sensor
Temperature sensor

The sensor allows the host hardware or software to monitor the memory device temperature to improve data reliability in the target application environment.

TRIM support
Trim support

The TRIM command allows the operating system to inform the SSD which blocks of data are no longer considered in use and can be wiped out internally, which increases system performance in following write accesses. With TRIM Support data scrap can be deleted in advance, which otherwise would slow down future write operations to the involved blocks.

Write Amplification Factor
WAF reduction

The WAF (write amplification factor) for MLC-based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.

Wear leveling
Wear leveling

Sophisticated Wear Leveling and Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.

Wide temperature support
Wide temperature support

Swissbit‘s embedded memory and storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).
