Samsung 840 Pro 256GB SSD Review

Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests, you can run a full test or just the read or the write test or you can run a single test, i.e. 4K DQ16.


Anvil Storage Utilities is not officially available yet but we've been playing with the beta for several months now. The author, Anvil on several international forums has been updating the software steadily and is adding new features every couple of months.


The software is used several different ways and to show different aspects for each drive. We've chosen to use this software to show the performance of a drive with two different data sets. The first is with compressible data and the second data set is incompressible data. Several users have requested this data in our SSD reviews.


0-Fill Compressible Data




Incompressible Data




The 840 Pro lost a little performance when working with 100% incompressible data (coming from compressible). The largest drop off came when writing sequential data.


Read IOPS through Queue Depth Scale




With the upper limits of SATA III reached nearly two years ago, both Samsung and OCZ turned to IOPS performance in their marketing material. Both companies spout on about 100K IOPS this and 100K IOPS that, but most of us rarely use anything higher than a queue depth of 8. Even getting to QD8 means heavy multitasking is taking place, but QD1, 2 and 4 are pretty common.


When it comes to read IOPS at low queue depths the Samsung 840 Pro 256GB just has more get up and go when compared to Vector 256GB. This is an important test for every type of users, especially people like me that build near supercomputers and then end up surfing the web more than anything else. Since this is read IOPS, disk intense apps like games (loading the files into RAM and start up), Photoshop (mainly startup) or for that matter just about any Adobe software will load faster with 840 Pro. The difference is not much, but as you'll see in this review these two drives are evenly matched.


Scaling Write IOPS through Queue Scale




That said, when it comes to writing small files, we see Vector has a bit of a lead here but again, not by much in this capacity size.
