PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
Starting off, we see the majority of these lower cost SSDs tend to stay within the same general range of speeds in both our create and copy tests. An outlier in copy is the Samsung 840 EVO, which has its TurboWrite caching struggle a bit when performing a simultaneous read + write back to the same drive. This test also completely fills that cache in short order, so the longer speeds would not be typical in normal usage unless you were continuously writing several GB of data at >300 MB/sec.
Circling back to the ARC and the Vertex 460, they appear to perform with reasonable similarity.

I know this is off topic, but whatever happened to intel’s DC P3500? Is that ever going to be released?

The DC P3500 is suppose to be released by the end of August. I am waiting to buy one when it does.

.50/GB is decent, but I would love to see everyday prices dip into the .30/GB range or below.
Think it won’t happen until
Think it won’t happen until we start making over 1.5tb in 2.5″
Based on how the SSD prices
Based on how the SSD prices have been declining in the last 2 years, I think that $0.30/Gb is obtainable within 2 years easily, regardless of whether or not 2.5″ 1.5Tb hard drives are available. I have had a 2.5″ 1Tb Hard drive since 2009 and there hasn’t been any indication that there is any demand for anything larger for a laptop. I have seen 2.5″ 2Tb hard drives but the height is too tall to fit in most laptops.
