Integral SVR-PRO 100 SRI 4TB SSD Review

Futuremark's PCMark 8 is a very good all round system benchmark but it's Storage Consistency Test takes it to whole new level when testing SSD drives. It runs through four phases; Preconditioning, Degradation, Steady State, Recovery and finally Clean Up. During the Degradation, Steady State and Recovery phases it runs performance tests using the 10 software programs that form the backbone of PCMark 8; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint, Word, Battlefield 3 and World of Warcraft. With some 18 phases of testing, this test can take many hours to run.

Preconditioning
The drive is written sequentially through up to the reported capacity with random data, write size of 256 × 512 = 131,072 bytes. This is done twice.
Degradation
Run writes of random size between 8 × 512 and 2048 × 512 bytes on random offsets for 10 minutes. It then runs a performance test. These two actions are then repeated 8 times and on each pass the duration of random writes is increased by 5 minutes.
Steady State
Run writes of random size between 8 × 512 and 2048 × 512 bytes on random offsets for final duration achieved in degradation phase. A performance test is then run. These actions are then re-run five times.
Recovery
The drive is idled for 5 minutes. Then a performance test is run. These actions are then repeated five times.
Clean Up
The drive is written through sequentially up to the reported capacity with zero data, write size of 256 × 512 = 131,072 bytes.

pcm08-avr-bandwidth

pcm08-avr-test-latency

pcm08-total-latency
The drive didn't handle PCM8 Consistency test too well with high latency results throughout the final parts of the degradation tests and when  in a steady state. It didn't recover too well from the ordeal either.
