The Lexar Lineup at a Glance
Internal options divide by bus interface and architecture. The Lexar NS100 uses standard SATA III, suiting legacy upgrades limited to 520MB/s. For high-speed internal slots, the Lexar NM790 operates over PCIe 4.0 with Host Memory Buffer technology for consoles and PCs, while the Lexar NM1090 PRO targets next-generation motherboards with PCIe 5.0 bandwidth and onboard DRAM caching.
Portable units separate through transfer speeds and enclosure protection. Standard USB-C models deliver 1050MB/s sequential throughput with optional hardware encryption for everyday file transfers. If you work in harsh field conditions or capture high-bitrate video, drives like the Lexar Armor 700 provide 2000MB/s speeds inside an IP66-rated, drop-resistant shell.
Who the Lexar Range Suits Best
You can choose capacities from 128GB up to 4TB across several distinct physical shapes. Internal hardware includes standard 2.5-inch drives and M.2 2280 sticks. Portable designs range from slim metal bodies and modular docks to rugged IP-rated casings and magnetic enclosures. None of these drives offer RGB lighting.
You should also note the hardware gaps across this lineup. The catalog offers no storage sizes above 4TB, and it skips the 256GB tier entirely. Furthermore, there are no compact M.2 formats like 2230 or 2242 cards.
You should also consider the best heatsinks for m 2 SSD to ensure your drive stays cool during heavy workloads.
How to Choose the Right Lexar SSD
-
Match the Internal Interface Generation
Check your motherboard or system expansion slot specifications before buying an internal drive. A modern motherboard with PCIe 5.0 slots can maximize sequential throughput with top-tier hardware like the Lexar NM1090 PRO 2TB. If your system only supports PCIe 4.0 or older SATA III connections, higher-generation drives will downclock or physically fail to connect. Older desktop and laptop bays often require standard 2.5-inch SATA connections instead of M.2 slots. Always confirm the exact bus generation and connector key supported by your motherboard manual before selecting a drive.
-
Evaluate Cache Architecture
Internal NVMe drives handle indexing and mapping tables using dedicated onboard DRAM or Host Memory Buffer technology. Drives that use Host Memory Buffer leverage a portion of your host computer system memory to manage operations. This design keeps overall drive power consumption lower. The Lexar NM790 4TB uses Host Memory Buffer instead of dedicated DRAM chips while still maintaining fast PCIe 4.0 operation and 3000 TBW write endurance. For systems where minimizing drive power draw and thermal output is essential, an HMB-based storage architecture provides a practical, low-overhead solution.
-
Check External USB Bandwidth
Portable SSD transfer speeds depend directly on your host port protocol. Drives rated for 2000MB/s require a USB 3.2 Gen 2x2 port to hit their maximum published speed. If you plug a fast drive into a standard 10Gbps USB-C port, your throughput will cap near 1050MB/s. The Lexar SL500 2TB reaches up to 2000MB/s when paired with compatible USB 3.2 Gen 2x2 equipment. Verify whether your laptop, console, or recording gear includes 20Gbps USB support so you know what real-world file transfer rates to anticipate.
-
Review Ingress and Durability Ratings
If you plan to use an external drive in field environments or outdoor shoots, check the physical durability specifications. Ingress protection ratings tell you how well the casing blocks dust and moisture. An IP66 rating signifies strong protection against dust ingress and high-pressure water jets, alongside drop resistance. The Lexar Armor 700 2TB features an IP66-rated enclosure built for harsh environments. For standard desk backups, a non-rated metal or plastic chassis suffices. Outdoor recording and travel scenarios benefit from confirmed water, dust, and impact protection.
-
Consider Hardware Data Security
When transporting confidential data, software passwords alone might not meet your security requirements. Check whether the drive features onboard hardware encryption, such as 128-bit or 256-bit AES. Some portable drives also integrate physical or wireless authentication layers. The Lexar TouchLock 1TB provides 128-bit AES encryption paired with smartphone NFC authentication to manage access without entering passwords on host computers. If you move sensitive files across public computers or shared mobile devices, dedicated hardware encryption ensures your stored data remains unreadable if the physical drive gets misplaced.
-
Verify Console and Clearance Limits
Adding an internal SSD to a gaming console requires verifying physical clearance and read performance specifications. Gaming consoles like the PlayStation 5 require M.2 NVMe drives operating over PCIe 4.0 with fast sequential read performance. Form factor clearance also matters, as tight slots often favor single-sided circuit boards that generate less trapped heat. The Lexar NM790 512GB meets PS5 requirements with its single-sided M.2 2280 build and 7200MB/s read speeds. Always check your console slot dimensions and speed thresholds before installing any M.2 drive.
Frequently asked questions
Does the Lexar NM790 work with the PlayStation 5?
Yes, the Lexar NM790 works inside the PlayStation 5. The drive uses a compatible M.2 2280 PCIe 4.0 interface that meets console expansion requirements. For example, the 512GB version achieves read speeds up to 7200MB/s in a slim single-sided layout. You can install it directly into the expansion bay to increase your console storage capacity.
What endurance rating does the Lexar NM790 4TB offer?
The Lexar NM790 4TB provides an endurance rating of 3000 TBW. This high-capacity M.2 2280 model uses a PCIe 4.0 interface and relies on Host Memory Buffer architecture instead of dedicated onboard DRAM to manage cache duties while maintaining low operating power. It handles heavy write workloads over its operational life.
How does the Lexar NM1090 PRO differ from PCIe 4.0 drives?
The Lexar NM1090 PRO runs on the newer PCIe 5.0 interface rather than PCIe 4.0. This allows higher theoretical bandwidth and faster sequential transfer rates on compatible Gen 5 motherboards. Additionally, the 2TB model includes dedicated onboard DRAM caching, unlike Gen 4 models that rely entirely on Host Memory Buffer technology to coordinate read and write processes.
What transfer speed does the Lexar SL500 portable SSD reach?
The Lexar SL500 portable SSD reaches transfer speeds up to 2000MB/s. It reaches this performance level when connected to a host device with a compatible USB 3.2 Gen 2x2 port. The compact metal enclosure supports high-speed backups and direct recording workflows, such as Apple ProRes video capture from mobile devices.
Can you install the Lexar NS100 in an M.2 slot?
No, you cannot install the Lexar NS100 in an M.2 slot. The NS100 uses a standard 2.5-inch enclosure measuring 2.75 inches wide and 0.28 inches thick. It connects exclusively via a traditional SATA III data and power cable, delivering read speeds up to 520MB/s for older desktop bays and 2.5-inch laptop drive compartments.
What environmental protection does the Lexar Armor 700 provide?
The Lexar Armor 700 features an IP66 rating for rugged environmental defense. This rating ensures protection against heavy dust ingress and high-pressure water jets. The enclosure also resists physical drops, making the 2TB external drive suitable for field use, outdoor shoots, and harsh working environments while sustaining transfer speeds up to 2000MB/s.
How does security authentication work on the Lexar TouchLock SSD?
The Lexar TouchLock 1TB secures your data using smartphone NFC authentication alongside hardware-level 128-bit AES encryption. Instead of requiring you to type a password, you tap a compatible smartphone against the drive casing to unlock your files. The portable enclosure also features magnetic mounting and drop-resistant construction for safe mobile use.
