Three PCI Express-Based SSDs: When SATA 6 Gb/s Is Too Slow
When it comes time to hunt down the ultimate in storage performance, you simply cannot settle for standard SSDs. Instead, look to PCI Express-based drives that circumvent the limitations of SATA. We have products from Fusion-io, LSI, and OCZ on the bench.
Compression Test: OCZ Ibis
OCZ Ibis Unused
We need to utilize more of the Ibis’s capacity to see great write performance. Otherwise, the write results are still above average and excellent for reads.
OCZ Ibis Used
Mainstream SandForce SF-1222 chips are used on each of the SSD modules inside the Ibis, which explains why the performance drops so significantly if the drive is hit with heavy use. Write performance may drop to levels of an old hard drive if OCZ's Ibis has to handle data that cannot be compressed.
