WD Blue 3D SSD & SanDisk Ultra 3D SSD Review (1TB) – Twins That Rival the Best

 ATTO DISK BENCHMARK VER. 3.05

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.

Our results in ATTO are fairly similar overall. Both drives delivered read and write speeds that meet or exceed their ratings of 560/530MB/s read/write. At the smaller file sizes, however, we can see that the WD Blue delivers slightly faster read speeds from 512B to 4KB.

CRYSTAL DISK BENCHMARK VER. 5.2.1 X64

Crystal Disk Benchmark is used to measure read and write performance through a 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.

Testing in Crystal Disk Mark shows us, again, very similar results with numbers that are right in line with their rated specifications. 4K speeds show to be almost identical for all intents and purposes. With 563/535MB/s sequential read/write speeds and 45/137MB/s 4K random read/write speeds, the WD Blue 3D SSD and SanDisk Ultra 3D both deliver great performance.

AS SSD BENCHMARK VER 1.9

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.

In AS SSD both drives receive overall scores of 1210 and 1216 points. Again, both are nearly identical. Both achieve 95K IOPS read and over 83K IOPS write numbers here. During the copy tests, they both deliver performance ranging from about 290MB/s slowest to just over 500MB/s.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) is the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

SanDisk

1TB SanDisk Ultra 3D Anvil

Anvil Storage Utilities once again confirms all the performance numbers we have been seeing, however, just as we saw with the original WD Blue SSD last year, sequential read comes in at just under 400MB/s. The WD Blue 3D SSD received a score of 5147 points and the SanDisk Ultra 3D received a score of 5184 points overall.

    Great-With 3D reaching the market,perhaps the “race to the bottom” is over.
    And we can send planer TLC and ram-less drives off to silicon heaven.

    Pretty please, can we get a review of the 250 size.
    Thanks

    HOW will we know we are getting new stock rather than old slow stock?? is there a model number or suchlike? they are highly priced in the uk 90gbp for 250gb

      Just look for “3D” when buying.

  • funny name !

    Shouldn’t they be called 3D SSDDD ?
