Review of Linux Compatibility

The SanDsik U100 SDSA5DK-128G is a 128Gb SSD hard disk.

On a newly installed Ubuntu 12.04 with ext4 file system the following transfer rates for reading and writing were achieved:

The reading transfer rate while using cache was approximately 4200 MB/s while reading from cache and 450 MB/s while reading from the buffer:

 Timing cached reads:   8352 MB in  2.00 seconds = 4180.38 MB/sec
 Timing buffered disk reads: 1350 MB in  3.00 seconds = 449.81 MB/sec

Without cache the reading transfer rate drops down to 350 and 400 MB/s respectively:

 Timing O_DIRECT cached reads:   730 MB in  2.00 seconds = 364.15 MB/sec
 Timing O_DIRECT disk reads: 1304 MB in  3.00 seconds = 434.28 MB/sec

The write speed test resulted in a transfer rate of approximately 350 MB/s:

1024+0 data sets in
1024+0 data sets out
1073741824 Bytes (1,1 GB) copied, 2,99235 s, 359 MB/s
