    About LEXAR

    Lexar SSD and RAM, SD and microSD cards in India | FGTech

    Lexar SSD and RAM are at the core of making your system feel fast and reliable, while SD and microSD cards and USB drives handle everyday storage and transfers. At FGTech, we focus on the Lexar products that matter most for laptops, desktops, and everyday data use in India.Every Lexar product you see here is genuine, backed by the official Lexar warranty and a GST invoice. If you are upgrading an old laptop, building a gaming PC, or need dependable storage for work and studies, this page will help you choose the right Lexar SSD, RAM kit or card and plug it into your setup.

    Lexar RAM at FGTech

    Lexar DDR4 and DDR5 RAM modules are a straightforward way to remove lag when you multitask. They follow standard JEDEC specs, so they work with most common boards as long as you match the right generation.

    Desktop RAM (UDIMM)

    Lexar DDR4 8 GB / 16 GB 3200 MHz: Ideal for: Office PCs and budget gaming systems that struggle once you open several apps and browser tabs.Lexar DDR5 16 GB / 32 GB: Ideal for: Newer Intel and AMD platforms where you want stable, non‑gimmicky RAM from a storage‑focused brand.

    Laptop RAM (SODIMM)

    Lexar DDR4 8 GB / 16 GB 3200 MHz SODIMM: Ideal for: Laptops that shipped with 4 GB or 8 GB and feel slow even after you add an SSD.

    Lexar Memory Cards for everyday use and 24/7 recording

    Lexar SD and microSD cards are also available at FGTech, which can be used in laptops with card slots, drones, action cameras, dashcams, and NVRs.

    Standard Lexar SD / microSD Cards

    Best for: Cameras, drones, phones, tablets and laptops where you record or move files but do not write to the card constantly all day.What to check: Capacity (64 GB, 128 GB, 256 GB and above) and speed class (U1/U3, V30 or higher for 4K video).

    Lexar High‑Endurance Cards For CCTV and Dashcams

    Continuous recording in a dashcam or security system wears cards faster than normal use. Lexar high‑endurance versions are built for this.Designed for: Dashcams, NVRs, IP cameras and video recorders that write 24/7 or on a tight loop.Rated by: Terabytes Written (TBW), which tells you how much recording the card can handle over its life, not just speed.Recommendation: For always‑on recording, choose a Lexar high‑endurance card. For occasional shooting or travel footage, a standard Lexar card is fine.

    Lexar SSD at FGTech

    Which Lexar SSD should you choose

    Start by checking what your system supports:Laptop or desktop with an M.2 PCIe slot → choose a Lexar NVMe SSD.Laptop or desktop with only a 2.5-inch bay → choose a Lexar SATA SSD.Desktop with both: use NVMe for the system drive and SATA for extra storage.If you are not sure what slot you have, share your laptop or motherboard model with the FGTech team, and we will confirm before you buy.

    Quick Capacity Guide

    240/256 GB: Basic work, browsing, a few key apps.480/512 GB: Everyday use plus some games and media.960 GB / 1 TB: Gaming libraries and creator workflows.2 TB: Large local storage when you do not want to rely only on the cloud.

    When to pick Lexar NVMe vs SATA

    NVMe uses PCIe lanes and can be several times faster than SATA in real transfers. You feel this in game load times, large file copies and overall system responsiveness.SATA SSDs are still a huge upgrade over mechanical hard drives and usually cost less per GB, especially for 1 TB and 2 TB sizes.If your system supports NVMe, make a Lexar NVMe SSD your main drive.If your system only supports 2.5 inch SATA, a Lexar SATA SSD is the correct and safe upgrade, and it still feels dramatically faster than an HDD.A simple rule you can even copy into banners: “If your laptop supports NVMe, pick a Lexar NVMe SSD. If it doesn’t, a Lexar SATA SSD will still make it feel new.”

    Quick answers before you buy

    Is Lexar a good brand for SSD, RAM and Memory Cards?

    Lexar has a long history in flash storage, formerly part of Micron, and makes reliable SSDs, RAM, and memory cards that follow standard specifications.Lexar was a part of Micron, one of the world's biggest DRAM and NAND makers, before becoming an independent brand. Its SSDs and memory cards are widely used worldwide, and its RAM modules follow standard specifications, so compatibility and reliability are in line with other mainstream brands.

    How much RAM should I aim for?

    8 GB: Basic browsing, office work, light study use.16 GB: Smooth everyday experience plus gaming and light editing.32 GB and up: Heavy multitasking, virtual machines, and serious creative workloads.If your laptop still has only 4 GB or 8 GB and feels slow after an SSD upgrade, a Lexar RAM upgrade often makes the single biggest difference.

    What if I am not sure whether my laptop supports NVMe or only SATA?

    If your laptop supports NVMe, pick NVMe. If it only supports SATA, a SATA SSD still makes it feel dramatically faster than an HDD.Look up your laptop model on the manufacturer's site and check the storage section, or simply share the model with FGTech support on WhatsApp. We will tell you whether a Lexar NVMe SSD or a Lexar SATA SSD is the safer choice before you buy.
