Solidata K8 1920E 2TB SSD Review – Highest Capacity 2.5″ Form Factor SSD To Date

TEST BENCH AND PROTOCOL

SystemOur analysis today will be conducted with our Asus Z77 Premium Test Bench. Clicking on any pictures or benchmarks will bring up a more easily viewable high resolution image.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide.

Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

Chassis

We would like to thank ASUS (P8Z77-V Premium), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage.  We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture.  Much of the software is free and can be downloaded simply by clicking on the linked title.

THE LSI SANDFORCE SF-1222 CONTROLLER

All SSDs are not created equal and many new SSD enthusiasts realize that when they test their new drive to confirm specifications and ensure all is in order. SandForce controlled SSDs, as in the Solidata K8-1920E SSD we are testing today, use compression techniques in storage whereas many others do not. This creates a bit of confusion when enthusiasts test the drive with random data through benchmarking programs such as AS SSD and Crystal DiskMark. The results seem to be lower than the listed specifications.

SandForce

The results actually present a false portrayal of the drives ability when compared to other drives such as Samsung, Crucial or Intel. It is for this reason that all of our comparison testing is done through PCMark Vantage. PCMark Vantage HDD Suite simply provides evaluation results based on transfer speeds reached through typical user patterns. Vantage provides a better testing medium, in that, it sees through the typical synthetic benchmarks and provides us with ‘true to life’ results of the drive.

CRYSTAL DISK INFO VER 5.0.5

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, power on information as well as the characteristics of the SSD. As much as many think very little can be learned from this result with absolutely no SMART data available, the fact that TRIM was not highlighted became very obvious.

Solidata K8-1920E SSD CDI

With this, we decided to run a new program called TRIMcheck in order to see if TRIM was working on the K8, to which TRIMcheck seemed to support the fact that TRIM was not working on the JMicron JMB393 controller. TRIMcheck is currently a hot topic in our SSD Forums where our forum expertise, along with the software developer, is helping to fine tune and solve any bugs that may arise.  The software is free and can be found here.

TRIMResponse

TRIM does not work with this RAID Controller as it doesn’t on most.  Don’t give up all hope just yet though as we explain the TRIM/GC comparison and key features that just might overcome this issue in our final analysis.
