5 out of 5 eggs 4TB: as can be expected from Samsung. 08/30/2016

This review is from: SAMSUNG 850 EVO 2.5" 4 TB SATA III 3-D Vertical Internal Solid State Drive (SSD) MZ-75E4T0B/AM

Pros: The below results are for the 4TB drive. Formatted NTFS, it shows 3.63 TiB free.

Benchmarks are below:

4TB 850 Evo over Startech USB 3.1 dock over 3.1 port (with 3.1 cable):
----------------------------
CrystalDiskMark 4.0.3 x64
Seq Read: 498 MB/s
Seq Write: 485 MB/s
Ran Read 4KiB: 38 MB/s
Ran Write 4KiB: 125 MB/s
Seq Read: 508 MB/s
Seq Write: 504 MB/s
Ran Read 4KiB: 34 MB/s
Ran Write 4KiB: 97 MB/s


4TB 850 Evo over SATA connection:
----------------------------
CrystalDiskMark 4.0.3 x64
Seq Read: 538 MB/s
Seq Write: 503 MB/s
Ran Read 4KiB: 291 MB/s
Ran Write 4KiB: 181 MB/s
Seq Read: 500 MB/s
Seq Write: 475 MB/s
Ran Read 4KiB: 36 MB/s
Ran Write 4KiB: 67 MB/s

Samsung Magician gives this a 540/533 read-write rating


And for reference, here is my 1TB 850 Evo version over SATA connection:
----------------------------
CrystalDiskMark 4.0.3 x64
Seq Read: 561 MB/s
Seq Write: 532 MB/s
Ran Read 4KiB: 262 MB/s
Ran Write 4KiB: 240 MB/s
Seq Read: 519 MB/s
Seq Write: 508 MB/s
Ran Read 4KiB: 41 MB/s
Ran Write 4KiB: 97 MB/s

...making the 1TB 850 version a very un-scientific 6% faster, all-around.
(Samsung Magician gives this a 553/532 read-write rating)

Cons: 4TB pricing is not at sweet spot, yet.

Other Thoughts: It should be the higher the GB, the cheaper per byte. The industry has the pricing model favoring 500GB drives. When PCI-e SS drives become cheaper/more popular, the bottlenecked speed of the SATA connection will drop the price of the larger sizes. And it's about time. We need to be able to use SSDs for storage drives.

5 out of 5 eggs The fastest platter drive I've had. 08/30/2016

This review is from: Seagate IronWolf ST10000VN0004 10TB 256MB Cache SATA 6.0Gb/s 3.5" Hard Drive Bare Drive

Pros: 1) Drive is 30 degrees C/ 86 F at max load: this drive will NEVER get warm to the touch.
2) Per GB, a deal over Enterprise 6TB and 8GB drives.

I got the 10TB drive, model number: ST10000VN0004-1ZD101
Formatted NTFS, the drive shows 9.08 TiB Free.

I first did a checkdisc, and after a day and a half, 2,440,952,352 free clusters were processed. Checkdisc reported 9.537TB total disc space.

A 4GB data copy (median size 388KB/ average 466KB) from my Primary (Samsung 850 Evo 1TB SSD) to this drive took 33 seconds.
(Including queue-up, this is 121MB/s.)

If you are in the market for an HD, you want one of three things:
1) Space, 2) Reliability, 3) Speed.
Likely in that order, since no one backs up to just one drive. For this drive, you are paying a small premium for the former.

This is a 7-platter/14 head drive. Here is the CDM benchmark:
----------------------------
CrystalDiskMark 4.0.3 x64
----------------------------
Seq R: 246 MB/s
Seq W: 244 MB/s
Ran R 4K: 2.1 MB/s
Ran W 4K: 2.3 MB/s
Seq R: 240 MB/s
Seq W: 245 MB/s
Ran R 4K: 0.9 MB/s
Ran W 4K: 2.3 MB/s

Seagate's 4TB Enterprise drives, that "broke the mold" in 2013, had 4 platters/8 heads:
Here is a benchmark of that drive (empty):
----------------------------
Seq R: 172 MB/s
Seq W: 147 MB/s
Ran R 4K: 2.0 MB/s
Ran W 4K: 2.4 MB/s
Seq R: 171 MB/s
Seq W: 147 MB/s
Ran R 4K: 0.7 MB/s
Ran W 4K: 2.2 MB/s

...Making this the fastest drive I have had.

From the WD platter drive to this drive, I copied 2TB (214k avg filesize) of data.
*Speed started at 95MB/s, and steadied at 52MB/s. (Windows' calculation factors in queue time as well.)
*Copying the data from the drive to itself (within another folder) moved data at 75MB/s.
*From SSD to this drive when empty, my 2TB of data steadied at 134MB/s.
*From SSD to this drive when 85% full, speed steadied at 101MB/s.

HD performance slows as it fills, for two reasons:
1) Old data is placed on mostly non-sequential areas of the discs
2) Outside portions of platters are written to, first. So, new data is written to the inside areas of platters...and in-side disc portions move available bit areas past the write heads at a lower rate.

You can see the trend, here.

Cons: I would like to test out the new WD 10TB Gold drive that just came out--though it is surely not worth the $700 price: reviews state a similar speed.

I planned for this to be one of several drives within my Synology NAS.
The problem with benchmarking drives within NASs is that, more often than not, for the SOHO, your NAS bottleneck is the CPU processes that occur when data is moved from one format (packets) to another (headers stripped, for placing data at rest). I don't have a second one to test in my NAS, so I can't tell you the improvement, there.

Other Thoughts: Doesn't work well as an arm floatie, though it's filled with helium. I put two on my daughter and that's the last I've heard of her.

StarTech.com USB 3.1 (10Gbps) Adapter Cable for 2.5

5 out of 5 eggs Great cable. One of my best purchases. 08/30/2016

This review is from: StarTech.com USB 3.1 (10Gbps) Adapter Cable for 2.5" SATA SSD/HDD Drives

Pros: Price. Buy two!

Cons: No cons.

Other Thoughts: I used CrystalDiskMark to help bench this cable, using my Samsung 850 SSD.


Internal SATA (control)
-----------------------------------------------------------------------
Sequential Read: 509 MB/s
Sequential Write: 504 MB/s



USB 3.1 cable over USB 3.0 port
-----------------------------------------------------------------------
Sequential Read: 349 MB/s
Sequential Write: 349 MB/s



USB 3.1 cable over USB 3.1 port
-----------------------------------------------------------------------

Sequential Read: 452 MB/s
Sequential Write: 473 MB/s


Thusly,
1) With this 3.1-rated Adapter Cable, over a USB 3.1 port, we achieve 91% the speed of the internal SATA; and,
2) With this Adapter Cable over a USB 3.0 port, we achieve 68% the speed of the internal SATA connection.

(These numbers may have been more telling outside of SATA, as USB 3.1 is rated faster than SATA)

lastly, with a
USB 3.0 cable over USB 3.1 port
-----------------------------------------------------------------------
Sequential Read: 353 MB/s
Sequential Write: 360 MB/s
...We can see that, by about 2%, the port is a LITTLE more important than the cabling, when either one has the 3.0 bottleneck.
