Today we are looking at the Western Digital SiliconEdge Blue 256GB solid state drive and compare its performance against some of the more recent SSDs we have tested.


Those of you who have been asking to see Intel X25-M G2 numbers can now stop emailing me. A drive passed through my office and before I let it set sail for Australia it took the opportunity to get a standard round of tests in.


Now that other manufacturers are releasing their next generation flagship models for the performance market, WD will have to use the SiliconEdge Blue to compete with a slew of Indilinx Barefoot controlled drives that have taken over the market. The X25-M is also a player here, but with only 80GB of space I am still holding firm to my belief that it is too small for enthusiasts and notebook users. RAID 0 is still not a very good option for most SSDs since there are not any controllers that are able to pass along the TRIM command.


ATTO Baseline Performance


Version and / or Patch Used: 2.34


ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.




In ATTO we see quite a bit of difference between WD's PR write numbers and what we came up with. ATTO is closer to the middle of our testing schedule, but surely the drive has not been hit so hard that the write numbers would take this big of a hit with only a handful of tests being ran before ATTO.
