Consumer vs. Enterprise SSD
A few weeks ago there was a benchmark about consumer SSD (some of the benchmarks wered flawed anyway:a cpu waiting for a hard disks goes to idle mode thus it doesn´t take power from the battery. When a CPU doesn´t have to wait for the disks, it doesn´t idle thus it takes more power. You have to factor in the work done from battery full to battery fully drained). This benchmark suggested, that SSD drives were not faster than harddisks. The problem: Many people think that the same is valid for enterprise SSD. You can´t use a benchmark of SSD drivers for netbooks for a SSD drive that costs as much or more than the complete netbook. Enterprise SSD and consumer SSD use different technology (SLC vs. MLC, different controller, more DRAM to cache). Let´s look at the datasheet of Intel SSDs. An Intel X25-E SSD is capable to deliver up to 35.000 IOPS read/3500 IOPS write at 250 MBit/s read/write (and it uses Single Level Cell NAND instead of Multi Level Cell NAND). This is vastly above the specs of a conventional rotating rust drive. So: When we talk about SSD usage in the enterprise, please forget all this stuff about SSD you may have read in your favourite PC hardware news outlet.
