small random
Quickbench's Standard Test includes random transfer test sizes from 4 KBytes to 1024 KBytes. The graph shows an average of 5 test cycles. Not as impressive as large sequential transfers, but reveals performance you can expect from certain applications which do small random transfers.
HIGHER number in megabytes per second = FASTEST
WHAT DID WE LEARN?
A single Accelsior Pro Q is much faster than a single Accelsior_E2 when doing large sequential transfers. It's even faster than a striped pair of E2s. And a single Pro Q has twice the storage capacity of top 960GB Accelsior_E2 model.
It is true that there are faster PCIe flash storage PCIe carrier cards sold by other companies, but even if you locate and purchase the scarce AHCI blades to populate them, the total cost of the solution is double that of the Pro Q.
There are solid state drives with higher capacity, but they transfer large sequential data at a fraction of the speed of the Pro Q.
You might say the Pro Q hits the 'sweet spot' of PCIe flash storage.
There are a few caveats.
- You can NOT use the Pro Q as a boot volume. That's due to the fact that the LSI controller requires a special driver.
- You must install a power feed. OWC provides the cable and instructions on how to connect it to the PCIe inlet fan's power port using a "T."
CONCLUSION
If you need a fast flash based storage for your pro projects, you should seriously consider the OWC Mercury Accelsior Pro Q.
