It seems you are running on Marvel SATA chipset. What motherboard are you using? You would get slightly better performance if you plug your SSD on Intel SATA chipset.

by default AS SSD and CrystaldiskMark write random data to your SSD to perform benchmark, its slower due to the data is incompressible(if im correct...)
If you want more accurate benchmark on AS SSD, click the "Tools" on the menu and run Compression-Benchmark.
For CrystalDiskMark, click the "File" on the menu > Test Data, All (0x00) or All (0xFF), both prolly same i think
The benchmarks numbers will be higher than "Default (Random)"
Its the same for ATTO bench.

as for the SATA 3GB/s cable vs 6GB/s cable, unless you are using cheapo cables, there is no difference between them in terms of performance

Yeah mv91xx is the Marvel SATA port, are suck
my M5A99X also got JMicron Sata port, SATA 3GB/s, the performance is much lower compare to AMD chipset with native SATA 6gb/s support.
Change mobo if you can, if your mobo dun have native Intel/AMD 6GB/s SATA port.

Got money buy SSD leh
mainstream Z77 should be enough and may solve your current slow  ssd performance problem.

Same as mine, im using HyperX but all the readings are wired cause my write speed(426MB/s) is higher than read speed(380MB/s), and its no where close to 500MB/s
Although i updated the SSD firmware but i didnt bothered to benchmark it again

if u have r3e just stick to sata 2 ssd. unless u have r3black then its ok coz it has better sata3 controller.

Getting a dedicated SATA card especially supporting SATA III is very expensive, as they are normally RAID cards with/without cache. Yes, there are cheapos out there, but all of them are using PCIe x1 interface, which itself already bottlenecks the SATA III bandwidth. These SATA cards are normally used for connecting hard disk.

You would be better off using the Marvel chipset first or changing the motherboard.

This kind of performance optimisation should really be done only if you have spare cash to burn or if you have an exceptional reason to do so. Compared to the feeling of owning your first SSD, this kind of upgrade will disappoint because you won't feel your computer getting twice as fast. It is really not worth staying on the brink of bankruptcy for.

guys,
i bought an SSD this weekend. the packaging is not similar to those online. here's mine:



Is there anything strange here? maybe old stock or new stock?

where did u bought?

Hi to all siffus here,
I want to upgrade my rig to an ssd and also the mobo.
I think I want to buy the 128gb crucial m4.
I have made my research that the mobo must have intel sata3 controller to maximize the ssd.
Does the Asus P8Z77-M have the intel sata3 controller?
I search at the asus website, but cannot find it.
