First my ssd: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
This is my first SSD I've ever gotten and was part of my first build. I am very pleased with it, however looking at some benchmarks, the write seems to be underperforming. Looking at the max Sequential Read and Write speeds, I should be getting up to 500MB/s Read and 475MB/s Write. According to CrystalDiskMark and AS SSD Benchmark, I'm getting about 505-435MB/s Read. Very happy with that. My write speeds however, aren't so great. I'm only getting about 175-165MB/s. My motherboard is the Gigabyte GA-990FXA-UD3 rev 4.0. From what I know all of my ports are SATA3 6Gb/s. I also think my ssd is plugged into the sata 0 port on the mobo, so I think I have it plugged into the right port.


All benchmarks were done with default settings, the exception being on CrystalDiskMark the number of passes was decreased to 2.
EDIT: Just realized upon posting that CrystalDiskMark had a very slow write speed. I'm not sure what the cause of this is. It normally reports to about 175-165MB/s.

Just an FYI, Port 0 has no significance. You could plug any SATA device into any SATA port on the motherboard. There is no "dedicated" port for certain devices.

How full is your drive? Is trim enabled? The results you are looking for come from a drive in a nice new state, it sounds like you have been using it more.

It has 62.2GB of 223GB free. I've had the drive for about a month almost 2 months

Here are the specs from PNY: http://www.pny.com/XLR8_SSD?sku=SSD9SC240GMDA-RB

Quote:
Performance
Max Read up to 400 Mb/s
Max Write up to 400 MB/s
Random Read/Write Operations (4kB) up to 70,000 IOPS Read / up to 40,000 IOPS Write
- See more at: http://www.pny.com/XLR8_SSD?sku=SSD9SC240GMDA-RB#sthash...


Different SSD manufacturers will use different benchmark programs to determine advertised read/write speeds. I believe that AS SSD and Crystal Disk Mark use incompressible data. Try again with the program "ATTO" and see if your results improve. ATTO uses compressible data, which is easier for SSDs to work with and generally gives higher scores.

Additionally, have you optimized your installation? Certain settings in the OS can have a major impact on benchmarks. Here is one optimization guide from SSD Review: http://www.thessdreview.com/ssd-guides/optimization-gui...

I have done most installations. I need to double check the bios to see if its set to AHCI or whatever, but here's the ATTO benchmark:
And according to PNY my read is excellent, but my write still is falling behind a bit.

It looks like your write performance is far short of PNY's advertised speeds. If you have performed all of the steps in the optimization guide, including enabling AHCI, then you should contact PNY Tech Support for additional help. You may have a bad SSD which needs to be replaced.

Checked my bios and it says AHCI. I'll get in touch with PNY's support.

I was thinking about buying this SSD. Is this a problem to not buy it or should I grab one?

Its a great drive. If you have the extra money (I think its only $10 or $20) I'd go with XLR8 Pro for the extra speed, but I haven't really noticed anything in every day use. Don't think its normal. Could just be a defect. These things happen every once and a while. I can keep you informed when I get a response back from PNY.
