m-systems diskonkey flash drive The first USB Flash Drive that I ever reviewed on Legit Reviews was the 16MB DiskOnKey Pro made by a company called M-Systems. M-Systems was later acquired by SanDisk, which was just acquired this year by Western Digital. The 16MB DiskOnKey Pro was available for $19.99, was marketed as being able to hold 11 floppy disks worth of data and was powered by a 32-bit ARM7 CPU. The fact that it has a processor inside was important back then as it was the first portable USB storage drive that was driverless and was able to run additional applications like automatic boot features and automatic logon.  Those were the first time those features were seen on a USB Flash Drive and since then millions of USB Flash drives have been produced and it's not a common device that most people have had the pleasure of using. The 16MB DiskOnKey Pro used the USB 1.1 host interface and was capable of up to 12 MBits/sec  or 1.5 MB/s of performance. diskonkey pro performance I still happen to have that drive and it's still in functioning order with data on it that hasn't been accessed in over a decade. I was able to run a really old version of SiSoftware Sandra 2004 that happened to be on the drive and find that it to find that the drive is capable of 1.45 MB/s sequential read and 1.36 MB/s write speeds. Those speeds were very respectable back in 2002/2003 for a USB 3.1 Flash Drive, but boy have we come a really far since then. HyperX Savage USB Flash drive The product that I'm looking at today is the HyperX Savage USB 3.1 Gen 1 device that just came out this month and is available in 64 GB, 128GB and 256 GB capacities.  This is the first USB Flash Drive that I've received that touts being compliant with the USB 3.1 Gen 1 specifications set by the USB-Implementers Forum (USB-IF) to take full advantage of the latest USB Type-A ports in newer devices. Since it's also backwards compatible with older USB ports, meaning that it will work on desktops, notebooks, gaming consoles (PS4, PS3, Xbox One, Xbox 360) and so on. It needs to be made clear to everyone that USB 3.0 has been retroactively renamed USB 3.1 Gen 1, so this is basically a SuperSpeed+ USB 3.0 drive that is capable of speeds up to 5Gbps. The new USB 3.1 standard that most think of when they see USB 3.1 on a device is actually called USB 3.1 Gen 2 and those devices are capable of up to 10Gbps transfer speeds. So, if you are shopping for a USB drive you need to know that USB 3.0 and USB 3.1 Gen 1 are the same thing. If you want a true 'USB 3.1' 10Gbps device you'll need to look for one that meets the USB 3.1 Gen 2 specification. https://youtu.be/38iQ1IjsbcE The HyperX Savage USB 3.1 Gen 1 series is capable of 350MB/s Sequential Read and 250 MB/s Sequential Write speeds on the 128GB and 256GB drives and 350MB/s read and 180MB/s write in the smaller 64GB capacity drive.
HyperX Savage USB Model Capacity Read Speed Write Speed Price
HXS3/64GB 64GB  up to 350MB/s  up to 180MB/s $52.37 shipped
HXS3/128GB 128GB  up to 350MB/s  up to 250MB/s $87.40 shipped
HXS3/256GB 256GB  up to 350MB/s  up to 250MB/s $164.84 shipped
When it comes to pricing the HyperX Savage runs  $52.37 for the 64GB, $87.40 for the 128GB and $164.84 for the 256GB version. These prices aren't bad for the speeds you get, but the pricing issue for Kingston will be the fact that SSDs are stupid cheap these days. You can buy an entry level SATA III SSD with a USB 3.0/3.1 enclosure for less or go with an USB 3.0 External SSD like the Samsung T1 Portable that we reviewed earlier this year. The Samsung Portable SSD T1 250GB model that we reviewed showed that it was capable of 463 MB/s read and 437 MB/s write speeds in the ATTO benchmark and it runs just $89.99 shipped. The Samsung Portable SSD T1 is cosidered a portable SSD though and isn't a true USB Flash drive. The negatives of this means that it's a larger device, that has a removable USB 3.0 cable, but it's far cheaper at $0.36 per GB versus $0.68 per GB on the HyperX Savage 128GB drive. HyperX Savage USB 3.1 The HyperX Savage is a great look USB 3.1 Gen 1 (USB 3.0) drive that features the infamous red HyperX logo and name on the side of the drive. The drive measures 76.3mm x 23.48mm x 12.17mm in size and has a removable cap that is stored on the other end of the drive. The cap clicks firmly into place if you aren't using a key chain as if you have it secured to a lanyard or key chain the cap obviously can't be used.

HyperX Savage USB 3.1 128GB Here is a look at the cap removed from the drive and the standard blue USB 3.1 Gen 1 / USB 3.0 Type-A port. Let's take a look at the test system and then the performance of this drive!  

Test System Configuration

Before we look at the numbers, let’s take a brief look at the test system that was used. All testing was done on a fresh install of Windows 8.1 Pro 64-bit and benchmarks were completed on the desktop with no other software programs running. Windows has had the power option set to high performance. ASUS X99 Sabertooth Motherboard
The Intel X99 platform that we used to test the HyperX Savage 128GB drive was based around the ASUS X99 Sabertooth motherboard with BIOS 2001 that came out on 11/18/2015.  We used the boards SuperSpeed+ USB 3.1 port to ensure the highest possible speeds.

HyperX Savage USB 3.1 Drive Performance

HyperX Savage USB Flash Drive

CrystalDiskMark 5.0.2 x64

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32. cdm-savage Benchmark Results:  On our desktop PC that uses an ASUS X99 Sabertooth motherboard with Windows 8.1 we found that CrystalDiskMark showed that we topped out at 429.5 MB/s sequential read and 213.5 MB/s sequential write on the boards integrated SuperSpeed+ USB 3.1 port. The 4K Random read and write speeds aren't that good at 10MB/s read and 0.02 MB/s write, so don't be planning on booting or running an OS off this USB 3.0 drive. 

ATTO v3.05

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB. atto-benchmark Benchmark Results: On ATTO we were able to get up to 350 MB/s read and 177MB/s write. Kingston advertises this drive as having 350 MB/s read speeds and 250MB/s for the write speeds, so we are spot on with the reads and a touch low on the write speeds. Note that the drive appears to have the best write performance with 64KB, 128KB and 256KB file sizes.

Anvil Storage Utilities 1.1.0

Anvil Storage Utilities is a very powerful tool that measures performance through a variety of tests which can be customized. Since some of the tests more or less duplicate what we get from other benchmarks we use already, we decided to use the IOPS (Input/Output Operations Per Second) testing on 4kb file sizes at a queue depth of 4, 16, and 32. IOPS performance is something SSD makers tout quite a bit but we generally don’t do a lot of IOPS testing because frankly a lot of users can’t relate to IOPS metrics as well and it tends to be more meaningful to the enterprise/server crowd. Still, it is another performance indicator with relevance and while some drives post good MB/s numbers, their IOPS scores aren’t always commensurate which this test will prove out. anvil-savage Benchmark Results:  We got 409.6 MB/s sequential read and 292.57 MB/s sequential write on the sequential 4MB file size tests on Anvil's Storage Utilities benchmark using 100% compression. Pretty solid results for a USB 3.1 Flash Drive!


Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation before being given to the Open Source Development Lab (OSDL) where it has remained since. iometer-hyperx-savage Benchmark Results:  The last test we wanted to make sure that the HyperX Savage drive wasn't using an SLC cache to have great burst speeds in quick benchmark tests and then slow down to much slower sustained speeds after the cache fills up when it's used in the real world to transfer large data files. We moved around some file folders that had about 50GB of images and videos on them, but wanted to show it in a benchmark and picked IOMeter for the task. We ran IOMeter for 60 seconds on the HyperX Savage to ensure that no marketing tricks were being used and found that none were. We set the test up on one worker with a queue depth of one and found that the read test was right at 385 MB/s and the write test was bouncing around 319 to 327 MB/s. Not bad considering this drive has 350 MB/s read and 250 MB/s writes and we far exceeded that. This test wrote nearly 20GB of data to the drive and would have easily filed up a caching solution if one was being used. Let's wrap this up!

Final Thoughts and Conclusions

HyperX Savage USB 3.1 The HyperX Savage is a great looking USB 3.1 Gen 1 drive that has pretty solid performance. This drive will likely get a fair bit of attention since it's one of the handful on the market being advertised as a USB 3.1 Gen 1 device. Just remember that USB 3.1 Gen 1 and USB 3.0 drives are basically the same thing as both are capable of 5 Gbps transfer speeds. You'll need to wait for USB 3.1 Gen 2 devices to come out to get 10 Gbps transfer speeds and the latest features that USB has to offer.
HyperX Savage USB Model Capacity Read Speed Write Speed Price
HXS3/64GB 64GB  up to 350MB/s  up to 180MB/s $52.37 shipped
HXS3/128GB 128GB  up to 350MB/s  up to 250MB/s $87.40 shipped
HXS3/256GB 256GB  up to 350MB/s  up to 250MB/s $164.84 shipped
  When it comes to performance the HyperX Savage was found to run at it's advertised speeds more times than not and for the 128GB drive I tested on that meant 350 MB/s read and 250 MB/s for sequential file transfers. These are pretty good speeds, but nothing to honestly write home about. I reviewed the Lexar JumpDrive P20 USB 3.0 drive over half a year ago and it is capable of similar speeds for a bit less money as the Lexar JumpDrive P20 128GB drive is available for $54.99 shipped with a lifetime warranty.  The Kingston HyperX Savage 128GB drive at $87.40 shipped with a 5-year runs you 60% more and is coming to market half a year later. The drive looks cool with the 'trend-setting design' that Kingston came up with, but it's lacking that killer feature that is needed to make it stand out in the crowded USB Flash Drive market. You have the Samsung SSD T1 250GB drive available for just a couple more dollars and then similar drives for far less. The price on the HyperX Savage USB 3.1 Gen 1 drive will drop over time like all products, but the current street price of $87.40 shipped is certainly better than the $131 MSRP! Legit Bottom Line: The HyperX Savage USB 3.1 Gen 1 Flash drive is fast and flashy, but was found to be lacking a killer feature that justifies the price tag. HyperX Savage USB Flash drive
