In this section, I will show you the speeds of the Glyph Atom Black 1TB SSD A1000BLK drive.  We will be checking out the performance using “ATTO Disk Benchmark”, CrystalMark’s “Crystal Disk Mark” and FutureMark’s “PCMark”.  Some of the tests might provide the same results but will solidify the performance and give you a better idea on the performance you can expect.  I test 3 times each test to give you a better average, not just a one-shot deal.

So that you can compare my results with what you may experience, I will give you my build list.

I will also provide you benchmark differences between USB 3.0 and USB-C.

  • ATTO Disk Benchmark (USB-C)

ATTO Disk benchmark measures raw transfer rates for both reads and writes from the disk and in this particular test we are measuring utilizing Overlapped I/O.  From 512KB on to 64MB, the speeds are consistently over 450MB/s speeds coming in at a max of 459,424 at the 512KB mark which is 459MB/s for write and under the same spot, 463,962 which is 463MB/s for read speeds.  Both at 512KB were the fastest speeds.

Next up is CrystalDiskMark.

  • CrystalDiskMark (USB-C)

CrystalDiskMark performs the following tests:

  • Seq: Sequential Read/Write Test (Block Size = 1024KB)
    • Sequential write/read is a disk access pattern where large contiguous blocks of data are written or written to or from adjacent locations on the disk
  • 4K: Random Read/Write Test (Block Size = 4KB)
    • 4K Random Read/Write are disk access patterns where small blocks (4K) of data are read or written from random locations on the drive.
  • 4K Q32T1: Read/Write 4KB Test (Block Size = 128KB) multi Queues & Threads
  • Seq Q32T1: Sequential Read/Write (Block Size=128KB) with multi Queues & Threads

At the 1Gig mark, we can see the speeds slow down a little here on CrystalDiskMark on the read, no so much on the write.  Coming in only 7 MB/s slower on the Q32T1 sequential write, but 33 MB/s faster on the Seq in regards to its rated transfer speed of 480 MB/s, it seems to advertise correctly.  They never really state where the transfer rates are recorded from only that those are the rates.

Coming up next, is FutureMark’s PCMark.

  • PCMark 8 (USB-C)

In FutureMarks PCMark 8, we can see the Storage test overall score was 4756.  We can also see a few of the benchmarks PCMark uses to come up with this score.  These scores are loading times for games like World of Warcraft and Battlefield 3 and application loading times of Adobe Photoshop, InDesign, After Effects and Illustrator as well as Microsoft Word, Excel and PowerPoint represented in seconds.  A little bit truer to life performance measurements and lower scores are better here.

Now that I have provided USB-C’s performance on the Glyph Atom Black and you have seen what the programs look like, I will provide the comparison between USB-C and USB-A 3.0.  This is so that you can make sure this is good for you in case you don’t have the USB-C interface on your computer.  These comparisons will be chart based, marking the overall performance leader of the 2 and you might be surprised.
