There have been many Solid State Drives released in the last couple of months, and today we are looking at the new 240GB Vertex 3 from OCZ which is tagged with the ‘Max IOPS' moniker. This drive has been tuned for users who require greater transactional throughput.
Today we will compare it with the standard 240GB Vertex 3 and the latest ADATA S511 250GB SSD, all of which use the Sandforce SF 2281 processor.
OCZ are claiming an IOPS 4k aligned result of 55,000 read and 65,000 write, compared to the standard Vertex 3 at 40,000 read and 60,000 write. Interestingly, the 120GB version has claimed IOPS figures of 35,000 read and 75,000 write.
| Product | OCZ Vertex 3 Max IOPS |
| Interface | Sata III |
| Controller | Sandforce 2281 |
| Size | 240GB |
| SSD Type | Multi Level Cell |
| Trim Support | Yes |
| Read speed (rated) | 550MB/s |
| Write speed (rated) | 500MB/s |
| MBTF | 2 Million hours |
To compliment the consumer model, OCZ have also released an Enterprise class drive, the Vertex 3 Pro, which uses the Sandforce SF-2582 controller and offers power loss data protection and data recovery protection.
The Vertex 3 we are reviewing today uses the SF-2281 controller which offers TCG OPAL security with 256bit AES encryption and an improved ECC engine (capable of correcting up to 55 bits per 512 byte sector).
All of the SandForce SF-2000 series controllers still utilise the patented DuraWrite technology, on the fly compression which reduces the size of the data written to the drive. When this is paired up with wear leveling and intelligent block management the drive will require fewer write cycles during regular use.
