I hate to say it but I just can't get past the cost of the Solidata K5. Even as an enterprise product that is designed to outlast the consumer drives by years, I just can't budge on this issue. The dark horse in the room is the Intel X25-E (enterprise SLC variant of the X25-M consumer SSD). In the U.S. the X25-E is available from Newegg for 749 USD, a little over 100 USD more than the K5. Intel has kept a pretty tight grip on their enterprise drives so we have not been given the opportunity to test the X25-E, but judging from the numbers that are floating around it runs a little faster than the M Series drives. The Solidata K5 performs as well as the Intel X25-M in most tests, but is considerably slower in the Database tests we performed.
After testing the Solidata K5 I was left feeling a little underwhelmed by the performance. In the past we have seen the SLC drives produce numbers that justify their high cost in relation to the MLC drives that were introduced at the same time. The K5 did outperform the MLC drives with the same controller in all of the tests, but not by the same margin as the previous showings. That said, the K5 is very fast and we are looking forward to testing the Solidata K6 MLC Indilinx drive.
