CRYSTAL DISK BENCHMARK VER. 3.0 X64
Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers. We have provided compressible (oFill) results on the left with incompressible (random data) results on the right.
We can see here that testing with incompressible data (right) results in significantly lower results than testing with highly compressible data on the left. Much of this can be attributed to the use of asynchronous NAND flash memory that results in somewhat lesser performance when moving incompressible data, however, keeps costs down. The typical user will never notice the difference in any case, as the higher performance results we see through testing with synchronous NAND flash memory would only be see with the user consistently transferring high volumes of incompressible data as we might see in photographs, video and music.
Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it tests in the worst case scenario for the most part with incompressible data.
AS SSD is another program which uses incompressible data in testing and this is evident in our transfer speed results although the low 4k random write speeds are excellent in all tests. More importantly though, AS SSD displays disk access times which are extremely low when considering them to a hard drive which averages around 9-10ms. This difference in access times is what will provide the visible performance upgrade observed when using an SSD equipped system.
ANVIL STORAGE UTILITIES PROFESSIONAL
Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. 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 utilize in our benchmark testing. Lets see how the OCZ Nocti 120GB SATA 2 mSATA SSD does in Anvil testing:
Anvil Utilities confirm what we have been seeing and once again show some incredible access times. Also, seeing a performance result of 45,276 IOPS at 4k QD4 disk access was rather unexpected for an SSD of such a small form factor. System and SSD identification is also shown on the lower left and right panels of the software result.
What makes the RunCore so much faster? Sych or toggle nand?
The Runcore T50 is a SATA 3 SSD which accounts for the lionshare of difference in its performance, however, it also uses synchronous NAND flash memory.
Ahh…sata 3…that would explain it..lol
You mentioned “talk now of cached SSDs present in the not far too distant future.” Are you talking about drives such as the synapse used to speed up platter based HDD’s or are you talking about sticking some higher speed memory (ram) on the silicon and using the ram as a cache for the ssd?
Its an interesting concept that would probably require ultrathin 7mm hard drives along with mSATA SSDs with caching software although your latter idea is very interesting.
If it ever comes to market i’d like to people to know that I submitted the idea. No trademarks necessary I’d just like recognition 😛
It looks like a UFO in that picture of the snow…2nd pine tree from the left..at the tip.
That is a UFO. We get tons of them in Canada. They were the first to put me onto SSDs you know. eheh
Have you tested this drive in the Z830? i have the standard tosh drive in my Z830 currently and would like to know if this is a worthy upgrade as the flaky nature of SATA3 discovered in the SSDReviews Z830 is not enough to swing me towards a SATA3 drive currently!
Yes this drive works fine in th Z830 and this is a SATA 2 drive.
excellent, so it shows better performance on the Z830 than the standard tosh drive (which we all know is frankly a bit pants) as in i wont be stuck on crummy 5.9 windows experience and woeful benchmark results in my shiny sexy Z830? 🙂
I am in Germany so I can’t test the WEI score with that drive but can assure you it is a huge step up from the Toshiba. As a matter of fact, any mSATA I have tested is a step up from the Tosh.
