Samsung PM1733 7.68TB NVMe U.2 SSD - Technical Review & Guide

2025/12/19 18:13:28

we are looking at the Samsung PM1733. This is an enterprise-grade NVMe U.2 SSD with a massive capacity of 7.68 terabytes.

As an engineer, I look for three main things: speed, reliability, and cost. In a busy data center, we cannot afford drives that fail or run slowly. The Samsung PM1733 is special because it is built to be a "Never-Die" SSD.

Samsung is a leader in flash storage. With this drive, they use the new PCIe Gen 4 technology. This is much faster than the older SATA or SAS drives we used in the past. Also, it uses the U.2 form factor. This means it looks like a standard 2.5-inch drive and fits easily into most modern servers.

Quick Specs

Here are the real numbers from the Samsung specifications.

Feature	Specification	My Notes
Model	Samsung PM1733	Enterprise Class
Capacity	7.68TB	Very high density. Saves space.
Interface	PCIe Gen 4 x4	The fast "highway" for data.
Read Speed	Up to 7,000 MB/s	Extremely fast.
Write Speed	Up to 3,500 MB/s	Good for recording large data.
Random Read	1,500,000 IOPS	Perfect for databases.
Random Write	135,000 IOPS	Optimized for reading data.
Endurance	1 DWPD (5 Years)	Reliable for daily use.
Key Tech	Fail-In-Place (FIP)	Keeps working even if a chip fails.

Why is it so fast?

The Samsung PM1733 is fast because it uses PCIe Gen 4.

To understand this, think of the connection between the drive and the computer like a highway.

1. Old SATA drives are like a small, one-lane road. Traffic gets stuck.

2. The PM1733 (NVMe) is like a wide, high-speed highway. It connects directly to the CPU.

According to the official data, this drive can read data at 7,000 MB/s. This is huge. It means you can open very large files instantly.

For servers, "IOPS" is often more important than raw speed. This measures how many small tasks the drive can handle at once. The PM1733 delivers 1.5 million Random Read IOPS. If you run a busy website or a database with thousands of users, this high number ensures the system does not slow down.

The "Never-Die" Features

Speed is good, but safety is better. Samsung added three very important features to protect your data.

Fail-In-Place (FIP) Technology

This is my favorite feature. Usually, if a memory chip inside an SSD breaks, the whole drive stops working. The server crashes. But the PM1733 is different. If one chip fails, the drive detects it, ignores the bad part, and keeps running. It fixes the data using backup copies. This means your server stays online, even if there is a hardware error.

V-NAND Machine Learning

Samsung uses smart software inside the drive. It constantly checks the health of the memory cells. It can predict problems before they happen. This helps the drive last longer.

Power Loss Protection (PLP)

What happens if the power suddenly goes out? The PM1733 has special capacitors (like small batteries) on the circuit board. If the power cuts, these capacitors provide just enough energy to save your active data. This prevents file corruption. For a business, this feature is required.

Final Verdict

The Samsung PM1733 (7.68TB) is not just a large-capacity storage device; it's a high-performance subsystem integrating intelligent error correction, self-healing capabilities, and virtualization acceleration.

Recommended Use Cases:

High-frequency trading and financial systems: Requiring extremely low latency and high reliability.
Cloud computing and virtualization: Utilizing SR-IOV technology to increase virtual machine density.
Content Delivery Networks (CDN): Leveraging the 7000MB/s read speed and 7.68TB large capacity to store hot data.

Purchase Recommendations:

Before purchasing, please ensure your server supports the U.2 interface and PCIe Gen 4 standard. Although it is backward compatible with Gen 3, using it in a Gen 3 slot is like driving a Ferrari on a dirt road – you won't be able to utilize its true potential.

If you're looking for a top-tier enterprise-grade SSD that you can "install and forget about" (because it's stable enough to require no maintenance), choose Jinxinyang. We offer short lead times, genuine, high-quality SSDs, and most importantly, affordable prices.
