ノートPC (UHXC3) のカードスロットで交換式HDD代わりとして購入。取説では512GBまででしたが、使えています。

2026-02-25    -ソニコン1

ノートPCのカードスロットに常時IN 、ただし、OSの書き込みキャッシュは無効のまま使用中です。5年前の512GB(amazon 販売)が結構前から一杯一杯で新しい写真を入れるたびに古いのを消して( 外付けHDD にコピー )いて、1TB が出たら、買い換えたいと思っていたのですが、出来れば購入歴のある SanDisk か 東芝 (KIOXIA) で、余り高くないのを と言うことで、今回 わりと安かったので購入に踏み切りました。ただ、取説によるとノートPC のカードスロットが 512GB に対応しているが、1TB 対応 を歌っていなかったので若干不安は有りましたが、870GB 程書き込みましたが、問題は出ていません。たまたまなのか、単に当時は512GBまでしか出回っていなかったので、512GBまで対応と書かれているかは分りませんが、私のはOKと。また、シーケンシャルリードの公称値を見るために、メーカー純正のカードリーダーも購入してテストしてみました。メーカーのカードリーダだと シーケンシャルのリードは公称の 170MB/s より少し遅く、ライトは公称の 90MB/s より少し早い結果になりました。ただ、ランダムが遅いです。ノートPC の方は、シーケンシャルは遅くなりますが、ランダムはメーカー品より速くなっています。基本はこちらで使用するので速度として問題ありません。ただし、ELECOM MR3C-D011（USB-C 接続）では、使用できませんでした。この製品も 512GB までの対応となっていて、こっちは本当に 512GB まででした。容量/空き容量 953.4GBカードリーダー：富士通 UHXC3 カードスロット-----------------------------------------------------------------------CrystalDiskMark 6.0.0 x64 (C) 2007-2017 hiyohiyoCrystal Dew World : https://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytesSequential Read (Q= 32,T= 1) : 91.654 MB/sSequential Write (Q= 32,T= 1) : 82.859 MB/sRandom Read 4KiB (Q= 8,T= 8) : 11.933 MB/s [ 2913.3 IOPS]Random Write 4KiB (Q= 8,T= 8) : 3.452 MB/s [ 842.8 IOPS]Random Read 4KiB (Q= 32,T= 1) : 12.207 MB/s [ 2980.2 IOPS]Random Write 4KiB (Q= 32,T= 1) : 3.392 MB/s [ 828.1 IOPS]Random Read 4KiB (Q= 1,T= 1) : 12.122 MB/s [ 2959.5 IOPS]Random Write 4KiB (Q= 1,T= 1) : 3.239 MB/s [ 790.8 IOPS]Test : 1024 MiB [N: 0.0% (0.0/953.4 GiB)] (x5) [Interval=5 sec]Date : 2021/04/07 21:11:27OS : Windows 10 Professional [10.0 Build 19042] (x64)カードリーダー：SANDISK SDDR-A631 (USB-C接続）-----------------------------------------------------------------------CrystalDiskMark 6.0.0 x64 (C) 2007-2017 hiyohiyoCrystal Dew World : https://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytesSequential Read (Q= 32,T= 1) : 151.452 MB/sSequential Write (Q= 32,T= 1) : 95.973 MB/sRandom Read 4KiB (Q= 8,T= 8) : 3.424 MB/s [ 835.9 IOPS]Random Write 4KiB (Q= 8,T= 8) : 1.567 MB/s [ 382.6 IOPS]Random Read 4KiB (Q= 32,T= 1) : 2.566 MB/s [ 626.5 IOPS]Random Write 4KiB (Q= 32,T= 1) : 1.580 MB/s [ 385.7 IOPS]Random Read 4KiB (Q= 1,T= 1) : 3.783 MB/s [ 923.6 IOPS]Random Write 4KiB (Q= 1,T= 1) : 1.507 MB/s [ 367.9 IOPS]Test : 1024 MiB [E: 0.0% (0.0/953.4 GiB)] (x5) [Interval=5 sec]Date : 2021/04/10 19:19:07OS : Windows 10 Professional [10.0 Build 19042] (x64)2021/07/26 追記アロケーションユニットサイズが512KBもあるのでご注意を。一杯になって、ファイルサイズの合計に対して。ディスク上のサイズが大きかったので、小さなファイルを沢山入れようとすると入りません。通信ログ(メールやチャット等のテキストファイル)が数GB占めていたので、こちらはノート本体のSSDに移動しました。四百MB位になりました。基本は写真用(JPG 約5MB ～)なので、問題無いです。

5.0 out of 5 stars Very nice and very very economical!

Alright fellow photogs and camera aficionados of the Amazon world, let's talk SD cards, shall we? Now, I'm rockin' the Lumix S5 IIX, which, yeah, she's a bit high maintenance and demands those UHS-II cards. But here's where things get interesting.Enter the SanDisk 128GB Extreme PRO SDXC UHS-I Card. While my Lumix loves those UHS-IIs for video, when it comes to snapping those killer stills, I've been leaning into the embrace of this SanDisk card. Why, you ask? A few tasty reasons.1. Price Tag Magic: Okay, so I scoped out a few places, and Amazon's price for this card? Pretty unbeatable. Like, 'is-this-a-typo?' level unbeatable. Compared to some other online giants (you know who I'm talking about), this is wallet-friendly territory.2. Performance: Don't let the UHS-I label fool you. This card is quick, reliable, and when capturing those high-res images, it does its thing and does it well. No lag, no fuss. Just pure, unadulterated photo goodness.3. Capacity & Quality: 128GB means I'm not in a rush to transfer photos every other day. And with SanDisk's rep? I'm confident my shots are safe and sound until I get around to it.In a nutshell? While UHS-II cards have their spot in the limelight (especially for video needs), for still photography, the SanDisk Extreme PRO SDXC UHS-I is like that sneaky, economical MVP in the background. If you're after quality, performance, and a price that makes you feel like you've pulled a fast one on the system, then give this card a shot. You might just be as pleasantly surprised as I was! 📸👌🛍️
