Weight

The four capacities of the WD_BLACK SN750 weigh the same without the heatsink. The SSDs should also weight the same with the heatsink. You can find the weight specifications below:

  • Without Heatsink: 7.5g ± 1g
  • With Heatsink: 33.2g ± 1g

Form Factor

The internal solid state drives in this versus guide have the same M.2 2280 form factor.

Dimensions

The dimensions are also identical for all capacity options of the BLACK SN750. You can find the measurements (which is displayed in length x width x height) below:

  • Without Heatsink: 80 mm ± 0.15 mm x 22 mm ± 0.15 mm x 2.38 mm
  • With Heatsink: 80 mm ± 0.15 mm x 24.2 mm ± 0.30 mm x 8.10 mm

Interface

The SN750 solid state drives utilize PCIe Gen3 (8 Gb/s, up to 4 Lanes) as the interface.

Sequential Read

The 1 TB version of WD BLACK SN750 with heatsink has the best maximum sequential read speed out of the group. Without the heatsink, the 500 GB and 1 TB versions are tied for having the fastest sequential read speeds.

You can that a look at the reading speeds below:

  • 250 GB WD BLACK SN750: Up to 3,100 MB per second
  • 500 GB WD BLACK SN750: Up to 3,430 MB per second
  • 1 TB WD BLACK SN750: Up to 3,430 MB per second
  • 1 TB WD BLACK SN750 with Heatsink: Up to 3,470 MB per second
  • 2 TB WD BLACK SN750: Up to 3,400 MB per second

Sequential Write

The 1TB Western Digital BLACK SN750 Solid State Drive also have the best sequential write speeds when compared to the other capacity options. The 2TB is the second best, followed by the 500GB version. The 250GB is the slowest at sequential writes.

You can take a look at the writing speeds below:

  • 250GB WD BLACK SN750: Up to 1,600 MB per second
  • 500GB WD BLACK SN750: Up to 2,600 MB per second
  • 1TB WD BLACK SN750: Up to 3,000 MB per second
  • 2TB WD BLACK SN750: Up to 2,900 MB per second

Random Read

Furthermore, the 1TB SN750 also offers the best random read speeds with the 2TB being the second fastest, 500GB being the third fastest and the 250GB being the slowest.

You can check out the random read specifications below:

  • 250GB WD BLACK SN750: Up to 220K per second
  • 500GB WD BLACK SN750: Up to 420K per second
  • 1TB WD BLACK SN750: Up to 515K per second
  • 2TB WD BLACK SN750: Up to 480K per second

Random Write

The story is the same when it comes to random writing. The 1TB is the best, followed by the 2TB, 500GB and then the 250GB.

You can find the random write specs below:

  • 250GB WD BLACK SN750: Up to 180K per second
  • 500GB WD BLACK SN750: Up to 380K per second
  • 1TB WD BLACK SN750: Up to 560K per second
  • 2TB WD BLACK SN750: Up to 550K per second

Endurance

Endurance is a measurement of how much data you can write on your solid state drive during its warranty coverage period. So, a 100 TBW means that you should be able to write 100 TB worth of data on an SSD. You can find the endurance specs for all the capacity options below:

  • 250GB WD BLACK SN750: 200 TBW
  • 500GB WD BLACK SN750: 300 TBW
  • 1TB WD BLACK SN750: 600 TBW
  • 2TB WD BLACK SN750: 1200 TBW

Warranty

The standalone and heatsink equipped versions of the 250GB WD BLACK SN750 NVMe SSD, 500GB WD BLACK SN750 NVMe SSD, 1TB WD BLACK SN750 NVMe SSD and 2TB WD BLACK SN750 NVMe SSD each come with a warranty period of 5 years or sooner if the TBW limit is reached.

Drive Writes Per Day (DWPD)

Drive Writes Per Day (or DWPD) measures how much data you can write on your solid state drive, in percentages, on a daily basis over its warranty period. In this case, the 250 GB has better endurance when compared to the bigger capacity options. You can take a look at the DWPD for each product below:

  • 250GB WD BLACK SN750: 43.8%
  • 500GB WD BLACK SN750: 32.9%
  • 1TB WD BLACK SN750: 32.9%
  • 2TB WD BLACK SN750: 32.9%

Mean Time to Failure

Mean Time to Failure measures the expected lifespan of a storage drive before it fails. The MTTF is the same for all the capacities at 1,750,000 hours.

Peak Power (10us)

The WD_BLACK SN750 drives have the same peak power of 2.8A.

PS3 Low Power

The 1 TB and 2 TB SSDs consume more energy at PS3 Low Power when compared to the 250 GB and 500 GB capacities:

  • 250GB and 500GB WD BLACK SN750: 70mW
  • 1TB and 2TB WD BLACK SN750: 100mW

Sleep PS4 Low Power

All four capacities use 2.5mW during Sleep (PS4 Low Power).

Operating Temperature

The solid state drives have the same operating temperature ranges of 32°F to 158°F (or 0°C to 70°C).

Storage Temperature

The Western Digital SSDs in this comparison also have the identical storage temperature ranges of -67°F to 185°F (or -55°C to 85°C).

Certifications

All four capacities received the following certifications:

  • BSMI
  • CE
  • FCC
  • KCC
  • Morocco
  • RCM
  • TUV
  • UL
  • VCCI
