Intel 160GB G2 average write / read speed: 93.6 / 215.6 MB/sec Crucial MX500 2TB 3D NAND SATA 2.5 Inch 214. The OWC Mercury Pro is so fast, that it’s right at the limits of the SATA bus for reads, and only a tad slower for writes. Crucial MX500 2.5' 2TB vs OWC Mercury Extreme Pro 6G 480GB Price comparison Crucial MX500 2.5' 2TB Product Store Price Crucial MX500 2TB 3D NAND SATA 2.5 Inch. No contest: the OWC Mercury Pro is blazingly fast and consistent. Its performance marks an important milestone with solid state drives, that of consistent performance under heavy use, and OWC deserves huge credit for bringing this high quality product to market. The 240GB OWC Mercury Pro was unfazed, running at astonishingly high speeds for reads and writes. Its read speed remained high, and read speed matters more than write speed for many (but not all) usage scenarios. This makes it unsuitable for use where consistent write performance is needed. However, the Intel G2 develops some severe write performance dropouts right down to 10MB/sec as seen in the orange lines in the graph below. its behavior is a huge improvement over the pathological behavior of the first generation units. The Intel 160GB G2 performed better than I expected it to: it did not degrade horribly as did the Crucial offerings. The graph tells it all at a glance: the red and green lines at the top are the OWC Mercury Pro. Its maximum performance is well below that of the OWC Mercury Pro, especially for writes. This unit is Intel’s second generation product, with improved algorithms for maintaining performance. Either the Pro or the Pro RE models are great choice for the MPG Pro Workstation or MPG Pro Laptop, depending on workload and/or whether RAID-0 striping is used.

More on all models of the OWC Mercury Pro. OWC does not support or warrant the 7% Pro model for RAID-0 striping use, taking a very conservative and commendable stance, though you can use it in RAID at your own discretion. Mercury Pro : 120 / 240 / 480GB, 7% over-provisioning Mercury Pro RE: 100 / 200 / 400GB, 28% over-provisioning (enterprise use, and for RAID-0) Remember, 7% over-provisioning is 7% more than most SSDs.

The main difference is 28% over-provisioning for the Pro RE model, and 7% over-provisioning for the Pro model, the idea being that intensive RAID use under 24 X 7 heavy duty applications deserves more set-aside for error correction and bad blocks.įor the vast majority of users with a single SSD, 7% over-provisioning is ample, yielding 20% more usable capacity at a slightly lower price. The 240GB Mercury Pro is a new model (May 2010), very similar to the 200GB Mercury Pro RE. Please see the previous page for details on this test.
