This one - ($529) OCZ Vertex 4 VTX4-25SAT3-512G.M has
Sustained Sequential Read: Up to 560 MB/s (SATA 6Gb/s)
Sustained Sequential Write: Up to 510 MB/s (SATA 6Gb/s)
Random 4k Read IOps: 90K IOPS
Random 4k Write IOps: 120K IOPS
While this one - ($616) Pny SSD9SC480GEDA-PB 480gb Prevail Elite has
Maximum Write Transfer Rate 520 MBps
Maximum Read Transfer Rate 550 MBps
Random IOPS: Up to 85,000
And this one - ($510) Intel 520 Series Cherryville SSDSC2CW480A310 has
Max Sequential Read Up to 550 MB/s (SATAIII)
Max Sequential Write Up to 520 MB/s (SATAIII)
But only
4KB Random Read Up to 50,000 IOPS
4KB Random Write Up to 42,000 IOPS.
That's why I'm asking. They are close on the read/write but the IOPS are big time different. As for the price??? It seems it's brand and size specific and not related to the iops.
I use the computer for gaming, video editing, CAD 3D drawing and some benchmarking, but only for fun.
