+Benchmarks:PNY Micro Sleek 16GB
+===============================

+== {doctitle}
+
+I bought a pair of USB2 PNY Micro Sleek USB sticks from my local tech shop
+today. I did quite a bit of research before purchasing them.
+
+While doing research on lifespan and actual read/write speeds, I discovered
+it's fairly difficult to find real benchmarks for any given usb stick on the
+internet. I can't speculate as to why, but I'll do my best to contribute a few
+benchmarks for mine.
+
+I'm going to rant for a few sentences here. Despite the dramatic increase in
+quantity of storage in recent years, the quality of the underlying "solid"
+storage and intermediate components have not increased at the same rate. For
+example, the USB 2 spec allows for transfer rates of around 480 Mb/s (roughly
+60 MB/s). If you've ever tested, you found that most USB 2 sticks only get
+around 6 \- 10 MB/s at best. Solid devices supporting the USB3 spec are even
+more disappointing. To the credit of the external HDD manufacturers though,
+external rotating drives are generally very fast by comparison (typically
+greater than 100 MB/s read/write)
+
+Please manufacturers, make better portable storage.
+
+Despite all that though, here is my benchmark.

+
+Write
+-----
+
+Write 1MB Block, 4096 Count (4GB of zeros)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    [root@null ~]# dd if=/dev/zero of=/dev/sdb bs=1M count=4096
+
+    4096+0 records in
+    4096+0 records out
+    4294967296 bytes (4.3 GB) copied, 495.355 s, 8.7 MB/s
+
+
+Write 1GB Block, 2 Count (2GB of zeros)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    [root@null ~]# dd if=/dev/zero of=/dev/sdb bs=1G count=2
+    2+0 records in
+    2+0 records out
+    2147483648 bytes (2.1 GB) copied, 248.904 s, 8.6 MB/s
+
+
+Writing a Real-world File
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You thought the previous write tests were bad? It took 208 seconds to copy a
+Fedora iso to the usb stick. Note that this iso file is coming from a ram disk
+that averages 3 GB/s read speeds.
+
+    [root@null ~]# dd if=/mnt/Fedora-Live-Xfce-i686-22-3.iso of=/dev/sdb
+
+    1697792+0 records in
+    1697792+0 records out
+    869269504 bytes (869 MB) copied, 208.453 s, 4.2 MB/s
+
+
+
+Read
+----
+
+NOTE: For these reads, we'll be writing the data to a ram disk to reduce the
+      possibility that the destination storage would be a bottleneck.
+
+Read 1MB Block, 4096 Count (4GB stream)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    [root@null ~]# dd if=/dev/sdb of=/mnt/dd.out bs=1M count=4096
+
+    4096+0 records in
+    4096+0 records out
+    4294967296 bytes (4.3 GB) copied, 153.179 s, 28.0 MB/s
+
+
+Read 1GB Block, 2 Count (2GB stream)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    [root@null ~]# dd if=/dev/sdb of=/mnt/dd.out bs=1G count=2
+    2+0 records in
+    2+0 records out
+    2147483648 bytes (2.1 GB) copied, 77.3436 s, 27.8 MB/s
+
+
+
+Summary
+-------
+
+Well, it seems these USB sticks are very "ho-hum". They average about 9 MB/s
+when writing zeros, 4.6 MB/s when writing real data, and 28 MB/s when reading.
+Keep in mind that the spec for USB2 allows for 60 MB/s. 4.6 MB/s is 7.6 percent
+of the spec's allowed maximum speed.
+
+My next test is to see how these hold up under six months to a year of use.
