The Biwin Black Opal NV7400, or NV7400 for short, supports a wide range of capacities from 512GB to 4TB. At the time of review, pricing was at $146.99, $258.99, and $420.99 for the three largest, but availability is spotty. It’s not too disappointing that the 512GB SKU is unavailable, as it’s slower, and 1TB+ is a more popular target. Prices right now are obscene, so it’s becoming more difficult to gauge them, but these are within the ballpark of what you should expect to pay for comparable hardware. As it stands, there are better deals to be had at all three available capacities, but prices are in constant flux, so do your due diligence.
The drive can hit up to 7,450 / 6,500 MB/s for sequential reads and writes and up to 1,000K / 900K random read and write IOPS. These are good but not exceptional numbers. It’s a good place to be for a PCIe 4.0 drive, and you don’t have to worry about it being underwhelming. The drive has a robust 1000TBW, or 1PBW, of warrantied writes per TB of capacity and is covered for five years. This is excellent write endurance, and if you’re someone who pays attention to that, make a note of this drive.
Biwin’s software platform is known as Biwin Intelligence, and it’s designed to work with a range of memory products: internal and external SSDs, mini SSDs, and CFexpress cards. It supports multiple functions, including S.M.A.R.T. reading, error scanning, performance testing, data backup, drive cloning, firmware updating, secure erasing, and the conveyance of drive and system information. This all-in-one SSD toolbox tackles everything you want for an SSD, and that could be a selling point if you don’t feel like meddling around with other free or paid software applications.
(Image credit: Tom's Hardware) (Image credit: Tom's Hardware) The NV7400 is a single-sided drive at all capacities, which is a good thing in our book. Single-sided drives have wider compatibility and are usually easier to cool. Some of Biwin’s past partners, such as Acer and HP, also use graphene labels to help spread heat, which works well in this configuration. It’s at least sufficient when the drive is not going to get ridiculously hot.
As we can tell from the label, this drive is designed for up to 3.3V/2.0A, which translates to under 7W. This matches the highest power state, which is pegged at 6.50W, compared to some high-end PCIe 5.0 drives that can get up to 11.5W. This is pretty reasonable, and the drive should operate fine without a heatsink.
