I just got the Intel 2.5-Inch 80GB X25-M Mainstream SATA II MLC Solid State Drive OEM SSDSA2MJ080G2C1 from Amazon, but according to the intel decoder H = high performace. so, what does J stand for?... flat performance?
No, idea as Intel's documentation isn't complete....
However, you got a 80GB X25-M G2: http://www.intel.com/support/ssdc/hpssd/sb/CS-029624.htm http://www.intel.com/support/ssdc/hpssd/sb/CS-029624.htm
All 80GB X25-M G2 perform identically.
