The A-DATA S599 is now packing MP2 firmware and extended capacity programming. On the performance side of things the new S599 also ships with high IOPS firmware that moves the maximum 4K write speed up to 50,000 IOPS.
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 can see the high IOPS programming come into play in the 4K write portion of the test. Standard drives are only able to achieve around 120 to 130MB/s, but the High IOPS drives hit 170MB/s or more. Here we see the A-DATA S599 writing 4K data at 174.7 MB/s.
A-DATA's performance claims of 280MB/s read and 270MB/s write appear to be close, but we were able to read and write data a little faster. For the most part the SandForce SF-1200 drives are maxing the SATA II interface on the motherboard and to achieve high numbers you have to have a high quality motherboard.
