The new Corsair GTX beats them all hands down for Windows to go and since my test machine is an older Sandy Bridge for XP compatability, the corsair is actually faster on the USB3 port than my Samsung 850 Pro is on the SATA2 ports Mushkin also has a bad rep for thermal issues on their Win2Go compatible thumbdrives Of course, not having Trim or Garbage collection exacerbates the problem which then accelerates the thermal throttling issue

I have not found any method other than Killdisk to temporarily regain full disk performance The CrapCleaner Drive wipe utility does not return full performance, and the new Defraggler SSD Optimizer does not return full performance
The only thing that will return the speed to "Like-New" condition is using Killdisk over the entire drive One of them is completely unusable after a week, one is so-so and one is very good (performance wise) I have 3 of the Sandisk Extreme Pro thumbdrives that are Windows to Go compatible as they are "Fixed Disks" The concern I have is Sandisk consistency of performance which cannot be checked using a single test drive Bullwinkle J Moose - Tuesday, Octolink It depends on the consistency of performance and not the peak.With extra overprovisioning the base performance of the WD Blue doesn't change but the upper limit of its normal band of performance increases to around 10k IOPS and the peaks reach 25k. Upon reaching steady state, the WD Blue varies from roughly 2500 IOPS to 5000 IOPS, with short bursts of slightly higher performance. Several other competitors have higher peak performance, but are either less consistent during the early phase of the test or don't last as long before dropping to steady state. The WD Blue has slightly worse performance consistency than the X400, but not low enough to be cause for concern.īefore reaching steady state, the WD Blue hovers between 20k and 30k IOPS, a significant improvement over the X400. The WD Blue overtakes the OCZ Trion 150 as the fastest planar TLC NAND SSD, but doesn't catch up to the MLC or 3D TLC drives. With a slight increase in out of the box overprovisioning, it is unsurprising to see the WD Blue improve on the SanDisk X400's steady-state random write performance. We use the last 400 seconds of the test to score the drive both on steady-state average writes per second and on its performance divided by the standard deviation. Any spare area will be exhausted early in the test and by the end of the hour even the largest drives with the most overprovisioning will have reached a steady state. The drive is filled before the start of the test, and the test duration is one hour. To maximally stress the drive's controller and force it to perform garbage collection and wear leveling, this test conducts 4kB random writes with a queue depth of 32. If a drive periodically slows to hard drive levels of performance, it may feel slow to use even if its overall average performance is very high. Some drives will exhibit very little variance in performance from second to second, while others will show massive drops in performance during each garbage collection cycle but otherwise maintain good performance, and others show constantly wide variance. In addition to an overall decline in performance, a long test can show patterns in how performance varies on shorter timescales. The performance in a worst-case scenario can be drastically different as over the course of a long test drives can run out of spare area, have to start performing garbage collection, and sometimes even reach power or thermal limits. Specifications for consumer drives typically list peak performance numbers only attainable in ideal conditions. Our performance consistency test explores the extent to which a drive can reliably sustain performance during a long-duration random write test.
