PNY Elite 480GB Portable SSD Review

ATTO DISK BENCHMARK VER. 2.47

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

PNY listed sequential performance number of 430MB/s read and 400MB/s write and, as we can see here, we are off to a great start!  Parallel 460MB/s speeds are great to see, considering this device is so compact.

CRYSTAL DISK BENCHMARK VER. 5.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Very rarely the case, but we are looking at Crystal Diskmark scores that both exceed manufacturers specifications.  For an SSD of this size, and an external one to boot, performance is absolutely crazy!

AS SSD BENCHMARK VER 1.7

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance.  For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
