The Large Capacity 4TB Drive Review

With the popularity of NAS drives increasing, manufacturers have responded by producing hard disks with capacities up to 4 terabytes (TB). These large capacity drives are perfect for bulk storage duties such as JBOD’s and compute servers. With a stated field-tested 1.2 million hour MTBF, these drives are designed to run 24/7 without sacrificing reliability.

Pegasuss offers an excellent bang for the buck option when it comes to large storage capacity hard drives. Although they lack some of the performance and extra features that more expensive options include, this may not matter if you plan on using your drive for things like photos, videos or programs you don’t use very often.

Large Capacity 4TB Drive: Ideal for Heavy Data Users

In our primary tests, the WD RE 4TB performed well, typically besting or sitting in the middle of the pack at the various thread and queue depth levels. During our testing, the drive did exhibit a slight increase in latency as it reached higher queue depth levels, but this was not a dramatic increase and would likely not be noticeable in normal use.

The WD RE 4TB also has good random write and read IOPS ratings. The max random write IOPS rating peaks at around 1,600K at QD32, while the max random read IOPS rating reaches about 2,400K. This is not nearly as high as a NAND SSD, but it’s still an impressive performance level for a single-sided, DRAMless HDD. Crucial does offer a premium heatsink for this drive, which you can use if you want to keep it cool in your desktop computer case.
