MATRIX 128GB 3D NAND Flash SATA 6GB/s 2.5 Inches Internal Solid State Drive (SSD), Read Up to 550MB/s, Write Up to 500MB/s, 5 Year Warranty

Using it for UBUNTU Linux,
with Consistent G41, core 2 duo e7500, Ddr3 8GB .

The data transfer within the SSD is about 165 to 200 mb/s.

For data transfer to another SSD:
Receiving data @ 40 to 60 MB/s,
and
Sending data @ 110 to 165 MB/s

The buffer speed is 172 MB/s with SATA 2

Data transfer to HDD
Received from HDD @ 40 to 60 MB/s,
Sending to HDD @ 60 to 80 MB/s

I purchased both zebronic SSD 128 GB and Matrix SSD 128 GB.
For matrix, the buffer speed is 172 MB/s,
For zebronics, the buffer speed is between 139 to 151 MB/s

performance wise, both are ok, but
For Data transfer, the Matrix is better
