SATA Blocks + OMAPl138 Linux

Other Parts Discussed in Thread: OMAPL138

 

Hi

 

In our custom application iam using  OMAPl138 for the data acquistion. In our application we will create dat files inside SATA and write hex data inside it. Iam planning to use just "fopen", "fwrite","fprintf" for the above application. For every fprintf or fwrite i planned to use buffer of size 1440 bytes.. Is it irregular size? as in SATA block size is multiples of 512?

if i write 1440 bytes, is this would cause reduced storage capacity, since we would be writing 1440 bytes in 1536 bytes (multiple of 512 bytes).

Kindly suggest me on this problem..

 

As per below link, 23.17 Mbytes/sec can be written when ARM operated at 300MHz and 98% cpu allocated to it.. This benchmark for Seagate Baracuda 7200 RPM HDD, what abt for SSD sata HDD??
