Phoronix: SanDisk 64GB Serial ATA 3.0 SSD On Ubuntu Linux
Another day, another new disk drive review at Phoronix. After this week having already shared our Ubuntu Linux test results for the Kingston SSDNow V300, Western Digital WD10EZEX, and Samsung 840 EVO, the solid-state drive for review today is the SanDisk 64GB SDSSDP-064G-G25.
Nice! Interesting to see SanDisk beat the EVO which gets good values in CrystalDiskMark.
I know CDM is not very close to a real world scenario, but it would be nice to have something that compares relatively straightly to CDM. Bonnie++ should be rather comparabe right, and from what I understand you support it in PTS, so it would be awesome if you ran those tests as well in these benchmarks.
Anyway great to see more SSD benches, hopefully you'll have a possibility to try AData SX900 and maybe some crusial SSDs as well in the same test system.

Guys, as an owner of 250GB version of Samsung 840 EVO, I did quite thorough research of my drive on the web before I bought it and the result is that is is one of the fastest SSD on the marked. This is clearly visible from numerous benchmarks all over the web, so I am afraid there is some serious problem with your tests. Are your filesystems alligned? Is 6Gb SATA really working? Do you have AHCI enabled and working? Do you have latest FW in all drives? there is no way that Samsung 840 EVO is so much slower than OCZ Vertex 3, actualy it is usually faster, sometimes significantly:
A 100% full partition that occupies 80% of the SSD space should be about the same for the SSD itself as an 80% full partition that occupies 100% of the SSD capacity (if the file-system has TRIM support). However, the file-system itself would greatly benefit from those extra 20% free space. So better just format it fully then make sure you never go above 80% capacity. This stands true even for partitions on rotating disks, after 80% performance of any file-system starts to rapidly decrease.
