Intel SSD Pro 2500 Series 240GB Enterprise SSD Review
ATTO & CrystalDiskMark
ATTO v2.47
ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB.
ATTO – Overlapped I/0:
Benchmark Results: ATTO showed Intel SSD Pro 2500 Series 240GB drive maxing out at 550 MB/s read and 525MB/s write in the standard overlapped I/O benchmark. This drive is rated at having up to 540MB/s read and 490MB/s write, so it looks like the drive is running as advertised so far.
CrystalDiskMark 3.0.3 x64
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
Benchmark Results: The Intel SSD Pro 2500 240GB drive scored 468MB/s read and 284MB/s write on the sequential test when we ran the drive on the CrystalDiskMark storage test with the default settings. The 4K scores were just shy of 33MB/s read and 120MB/s write. We also ran the 0Fill test and found that the sequential read/write performance of the drive jumped up to 511MB/s read and 508MB/s write with the highly compressible 0x00 (0 Fill) data. It looks like this drive favors compressed data, but that has been a trait of SF-2281 based drives since they were brought to market in 2011.
