        "content": "I looked into it \u2014 Dell\u2019s \u201cFlexBay\u201d trays and caddy/tray assemblies come in different materials depending on the model and use. Here\u2019s what I found specifically for the Precision 7960 (FlexBay) vs Precision 5820 (T-series) workstations, and whether the trays are plastic like consumer-grade or more \u201cserver-grade\u201d (metal, heavy duty).\n\n---\n\n## What we know about the Dell Precision 7960 FlexBay trays\n\n- The 7960 uses *FlexBay* modules/trays for SSDs (M.2 NVMe) and for SATA/SAS/HDD/Slim optical, depending on configuration. ([storagereview.com](https://www.storagereview.com/review/dell-precision-7960-review?utm_source=openai))  \n- The trays for the front FlexBays (especially for M.2 NVMe SSDs) are \u201cquick-release sleds/carriers\u201d that allow access without opening the chassis. ([storagereview.com](https://www.storagereview.com/review/dell-precision-7960-review?utm_source=openai))  \n- However, I could **not** find anywhere in Dell\u2019s official documents or reviews that state clearly whether these sleds are made of plastic, metal, or a combination. None of the spec sheets or teardown-review photos explicitly confirm material composition of the trays. ([storagereview.com](https://www.storagereview.com/review/dell-precision-7960-review?utm_source=openai))\n\n---\n\n## What we know about Dell Precision 5820 HDD / drive tray caddies\n\n- The caddy for 3.5\" HDD (model IB5IFK200-600, also referred to as drive \u201ccarrier/tray\u201d or \u201ccaddy\u201d) for the 5820 / 7820 / 7920 T-series is advertised with its dimensions & weight. One listing has the tray (empty) 1.50 lbs. ([pcserverandparts.com](https://pcserverandparts.com/dell-t7920-t7820-t5820-3-5-hdd-caddy-no-2-5-insert-ib5ifk200-600/?utm_source=openai))  \n- Most photos and stock images show this tray has metal framing/sheet metal pieces (sides/rails), perhaps a mix of sheet metal and plastic components (e.g. front bezel Insert, clips) \u2014 but metal seems prominent. ([parts.theserverstore.com](https://parts.theserverstore.com/products/1b51fk200-600-dell-precision-t5820-t7820-t7920-3-5-hard-drive-tray-caddy?utm_source=openai))  \n- Dell\u2019s 5820 service / parts manual refers to \u201chard disk drive assembly\u201d / \u201chard disk drive carrier\u201d (or \u201cHDD carrier\u201d) as components to be removed/installed. The term \u201ccarrier\u201d often implies a metal cage or tray piece built to endure mechanical stress. ([dell.com](https://www.dell.com/support/manuals/en-us/oth-xlt5820/precision_5820_om_pub/physical-specifications?guid=guid-b72f87d2-95d0-4400-932e-56d24a29709b&lang=en-us&utm_source=openai))\n\n---\n\n## Comparison & conclusion: Are 7960 trays like 5820 / server-grade?\n\nGiven the info:\n\n- The 5820's HDD caddy (IB5IFK200-600) appears to be a more traditional, robust drive carrier with significant metal content \u2014 fitting of \u201cserver-grade\u201d durability to hold 3.5\" drives and integrate with hot-swap bays.  \n- The 7960\u2019s FlexBay sleds for SSDs are more likely lighter duty in terms of mechanical strength (since SSDs are small, no moving parts), and built for fast access, so the tray parts may use more plastic or lighter materials (plastic frames / clips) combined with metal where needed.  \n\nBecause Dell designs each model / type of drive tray specifically for the use case (SSD vs HDD, front vs rear bay, weight/heat load etc.), **you shouldn\u2019t assume the 7960 FlexBay trays have the same material / durability as the 5820\u2019s HDD caddies**. The 5820\u2019s trays are more likely to be metal/server-grade; the 7960 trays may be mixed or plastic for parts, especially for SSD sleds.\n\n---\n\nIf you want, I can try to locate teardown photos that show the *exact material breakdown* (metal percentages etc.) of the 7960 FlexBay trays so you can see for yourself. Would you like me to pull those up?"

([dell.com](https://www.dell.com/support/manuals/en-us/oth-xlt7960/precision-t7960-setup-and-specifications/internal-slots?guid=guid-0d264016-5866-4e3f-bb1e-fa99b9656956&utm_source=openai))\n\nHere are a few details:\n\n- The 8 external-facing FlexBays are divided equally: four at the front and four at the rear.
