ADATA SP920 SSD Review – Capacity, Speed, Value and Something Unexpected

ATTO DISK BENCHMARK VER. 2.46

 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.

ATTO Disk Benchmark validates initial specifications for the most part but the speed increase while file size progresses also shows us that the SSD is a solid drive as it is a gradual steady progression.  This performance is great to see in ATTO, but will be even better if it remains such while testing with incompressible data.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or 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.

High sequential throughput drops a bit as is normal with this benchmark program, but pay particular attention to the low 4K random write transfer speed of 118MB/s.  This is a very high result and great to see out of a notebook SSD, the standard of which is still below 100MB/s in most SSDs.

AS SSD BENCHMARK VER 1.6

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.

Even the IOPS are decent, although a bit lower than specifications.

.ISO and Game transfer speeds and transfer times are excellent and both SATA 3, although many seem to have a bit of difficulty in the transfer of the program file.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil Storage Utilities (ASU) are 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.

Anvil seems to confirm much of what we have seen and it also allows us the opportunity to configure our tests to see if we can match listed specifications, at least as far as IOPS go.  IOPS results above 94K and 84K bring us a bit closer to what they had achieved in IOMeter.

Does the ADATA also come in the mSATA format? I need a 128GB drive for my Drobo and my Plextor M5M died. 🙁 (but under warranty :D)

Excellent review Les ^_^ always nice bargain with additional package from ADATA Premier Pro SP920 with that price 🙂

Looks like Adata is using 128Gbit die flash across all the capacities. This would also explain lower write speeds on smaller capacities.

One thing does come to mind though. Considering m550 and s920 are basicly the same drive and have the same firmware, to which 3rd party are these companies outsource firmware ?

In either case, this looks like a nice drive. Lets just hope street prices will be low 🙂
