Not repeatedly plugging/unplugging. ([windowscentral.com](https://www.windowscentral.com/sandisk-ultra-fit-review?utm_source=openai))  \n- Reading data is very fast; streaming media, opening files works reliably.  \n- Affordable way to get extra \u201cleave-in\u201d storage. Good value per gigabyte.

It overheats, slows down, sometimes disconnects.

Most are happy with storage size, value, speed and shape. But many mention heat issues, mostly when handling large transfers. ([bestbuy.com](https://www.bestbuy.com/site/sandisk-ultra-fit-128gb-usb-3-1-flash-drive-black/6182929.p?skuId=6182929&utm_source=openai))  \n- **ShopSavvy TLDR (May 2026)**: praises speed up to 400 MB/s (reads), compact size, reliable brand, but notes lack of ruggedness and features like waterproofing. ([shopsavvy.com](https://shopsavvy.com/reviews-tldr/sandisk-128gb-ultra-fit-flash-drive?utm_source=openai))  \n- **Technical reviewers** (e.g. Windows Central): the Ultra Fit is \u201cslim, simple,\u201d \u201caffordable,\u201d \u201cgood for basic semi-permanent storage.\u201d Criticisms: plastic housing, very small size (easy to misplace), average write speeds. ([windowscentral.com](https://www.windowscentral.com/sandisk-ultra-fit-review?utm_source=openai))  \n\n---\n\n## \u2699\ufe0f Verdict: Are Ultra Fits Reliable?\n\nDepending on *how* you plan to use them, yes\u2014but with caveats.\n\n- If you need **low-cost, compact read-heavy storage** (movies, photos, media that\u2019s written once or infrequently, and mostly read), then Ultra Fit is a good choice.\n- For **frequent writing, backups, or moving large files often**, the overheating risk and throttled write speeds become a problem. In that scenario, you might be better off with a more premium drive (metal build, better heat dissipation, higher write-durability).\n\n---\n\nIf you like, I can pull up some long-term endurance tests or comparisons (SanDisk vs Samsung vs others) to see how Ultra Fits stack up in real usage over 2-3 yrs."

If you need a drive with USB-C or dual-type connectivity, SanDisk\u2019s \u201cDual Drive\u201d or \u201cUSB-C\u201d models are the ones to look at.

Low price + less known brand = need to verify legitimacy.

        "content": "Yes\u2014both the **SanDisk Extreme Fit USB-C** and the **Extreme PRO USB-C** can heat up under certain conditions. It\u2019s pretty normal, especially during high-speed data transfers or extended use. That said, overheating can lead to throttling or performance drops if it's sustained. Here's how they compare and what triggers the heat.\n\n---\n\n## \ud83c\udf21 Official specs & normal limits\n\n- Both drives are rated for an operating temperature of **0\u00b0C to 45\u00b0C**. ([documents.sandisk.com](https://documents.sandisk.com/content/dam/asset-library/en_us/assets/public/sandisk/product/usb-flash/extreme-pro-flash-drive-usb-c/datasheet-extreme-pro-flash-drive-usb-c.pdf?utm_source=openai))  \n- SanDisk notes that metal drives (like the Extreme PRO) absorb and emit heat more efficiently\u2014meaning they often feel warmer than plastic-bodied ones, especially when under load. ([support-en.sandisk.com](https://support-en.sandisk.com/app/answers/detailweb/a_id/46290?utm_source=openai))  \n\n---\n\n## \ud83d\udd0d Heat in real-world use\n\n### SanDisk Extreme Fit USB-C\n- It has a plastic body, which reduces heat sinking. Reviewing tests show it hits up to ~400 MB/s reads, but sustained write performance drops quite a bit\u2014~130-180 MB/s. That gap usually correlates with rising temperatures when moving large files. ([storagereview.com](https://www.storagereview.com/review/sandisk-extreme-fit-usb-c-review-tiny-drive-big-convenience?utm_source=openai))  \n- It's designed to be ultra-compact and small enough to stay plugged in most of the time. Being so tiny with exposed plastic may reduce hot-spots but also limits heat dissipation. ([storagereview.com](https://www.storagereview.com/review/sandisk-extreme-fit-usb-c-review-tiny-drive-big-convenience?utm_source=openai))  \n\n### SanDisk Extreme PRO USB-C\n- Built with a metal shell, which acts as a heatsink. Good for conduction, but metal also feels hotter to touch. ([sandisk.com](https://www.sandisk.com/products/ssd/external-ssd/portable-ssd-sandisk-extreme-pro-usb-3-2?sku=SDSSDE&utm_source=openai))  \n- In tests (e.g. the Extreme PRO v2), when writing large amounts of data (dozens of GB), surface temps climbed: \u2248 40-48 \u00b0C, sometimes more internally. At those levels, while it's warm, performance was still good and seldom throttled painfully under typical loads. ([tomshardware.com](https://www.tomshardware.com/reviews/sandisk-extreme-pro-v2-portable-ssd-review/2?utm_source=openai))  \n- Long sessions (video work, backups, constant writing) are when it gets noticeably warmer. ([cameralabs.com](https://www.cameralabs.com/sandisk-extreme-pro-v2-portable-ssd-review/?utm_source=openai))  \n\n---\n\n## \u26a0 Potential drawbacks of heat\n\n- **Throttling**: When temps get high, the drive may reduce speed to protect itself. This is more likely in the Extreme PRO (because of the faster interface and more intense workloads) but can also happen if the Fit is used heavily. ([tomshardware.com](https://www.tomshardware.com/reviews/sandisk-extreme-pro-v2-portable-ssd-review/2?utm_source=openai))  \n- **Risk of data loss or drive instability**: Especially if the drive disconnects or fails during long transfers; some users report drives disconnecting or failing when too hot. ([forums.sandisk.com](https://forums.sandisk.com/t/sandisk-ultra-fit-usb-drive-gets-extremely-hot-and-keeps-disconnecting/418449?utm_source=openai))  \n- **Wear and lifespan**: Operating near the upper limit of temp specs over time can shorten lifespan. SanDisk notes that using the drive outside its intended temperature range \u201cmay lead to slower speeds and shorter lifespan.\u201d ([support-en.sandisk.com](https://support-en.sandisk.com/app/answers/detailweb/a_id/46290?utm_source=openai))  \n\n---\n\n## \u2705 Verdict: Do they overheat? Is it \u201ctoo much\u201d?\n\n- If your use is light to moderate\u2014copying files now and again, media storage, etc.\u2014you\u2019ll likely be fine with **Extreme Fit**; it\u2019ll warm up under load, but not dangerously so.  \n- If you\u2019re doing heavier work (editing large video files, frequent transfers, long sessions), the **Extreme PRO** handles higher load better and maintains speed more reliably\u2014though it\u2019ll feel hotter.  \n\n---\n\nIf you tell me how you plan to use the drive (how much data, how often, what device), I can help judge which one will stay cooler *in your workflow*."

([servnetuk.com](https://www.servnetuk.com/product/lenovo-thinkpad-x9-15-aura?utm_source=openai))  \n- The configuration it currently refers to is **Intel Core Ultra X7-358H**, 32 GB LPDDR5X-9600 soldered RAM, 1 TB PCIe Gen 5 SSD, and a 15.3\" 2.8K OLED non-touch display. ([servnetuk.com](https://www.servnetuk.com/product/lenovo-thinkpad-x9-15-aura?utm_source=openai))  \n\n---\n\n### \ud83d\udca1 64 GB vs. 32 GB in this model\n\n- The RAM in this machine (both 32 GB and 64 GB variants) is **soldered** onto the motherboard\u2014there are no RAM slots. That means you **cannot upgrade** the memory later; you must pick the correct configuration at purchase. ([servnetuk.com](https://www.servnetuk.com/product/lenovo-thinkpad-x9-15-aura?utm_source=openai))  \n- The 64 GB version is a **factory-order option** for this same model number (21VV0033UK); i.e. it uses the same base model, but with RAM swapped to 64 GB at manufacture. ([servnetuk.com](https://www.servnetuk.com/product/lenovo-thinkpad-x9-15-aura?utm_source=openai))  \n\n---\n\n### \ud83d\udd22 Model number(s) for the 64 GB configuration\n\nWhile the 64 GB option uses the base 21VV0033UK model family, there * doesn\u2019t appear to be a separate publicised sub-part number specifically for the 64 GB variant listed in the sources I\u2019ve found. The \u201c21VV0033UK\u201d label seems to refer to the general configuration line, which can be ordered with either 32 GB or 64 GB of RAM. ([servnetuk.com](https://www.servnetuk.com/product/lenovo-thinkpad-x9-15-aura?utm_source=openai))  \n\n\u2014 Sometimes vendors or Lenovo themselves will append suffixes like \u201c/64G\u201d or similar to clarify RAM size, but I couldn\u2019t find a confirmed \u201c21VV0033UK-64GB\u201d part number in the official PSREF or vendor listings.  \n\n---\n\nIf you want, I can check UK Lenovo\u2019s site specifically to see if there is a unique SKU or part number already assigned to the 64 GB factory variant. Do you want me to do that?"
