2.5.3 Electromagnetic Immunity

mSATA is an embedded product for host systems and is designed not to impair

with system functionality or hinder system EMI/FCC compliance.

2.6 Reliability

Table 2-12: Reliability Specifications

Parameter Value

Nonrecoverable read errors (BER)

<1 sector in 10

bits read, max

Mean Time Between Failures (MTBF)

3,000,000 hours

Power On/Off Cycles

50,000 cycles

Read Endurance Unlimited

Write or Erase Endurance

(specified by the flash component)

Global wear-leveling ~ 2% between least worn and most worn

Data retention >10 years

Notes:

1. BER will not exceed one sector in the specified number of bits read. In the extremely unlikely event

of a non-recoverable read error, the drive will report it as a read failure to the host; the sector in

error is considered corrupt and is not returned to the host.

2. MTBF is calculated based on a Part Stress Analysis. It assumes nominal voltage, with all other

parameters within specified range. Telcordia method SR-332, component FIT rate at 55

3. Power On/Off Cycles defined as power being removed from the drive, and then restored. Note that

host systems and drive enclosures may remove power from the drive for reasons other than a

system shutdown.

4. SLC NAND has a higher endurance then MLC NAND

2.6.1 Data, MetaData, and Firmware Code Protection

mSATA implements data protection throughout its data path. Protection

techniques include:

 Data ECC Algorithms

 Datapath CRC Error Detection

 RAISE

Data Protection Against Catastrophic Flash Page/Block Failure

2.6.1.1 DATA ECC Algorithms

The following data error correction is provided:

 For Flash memory devices providing 128 bytes of redundancy per 4K of

data (normally this is SLC Flash)

o 16 bytes of redundancy applied to 512 bytes of data

o Up to seven 9-bit symbols (up to 63 bits if contiguous) correctable
