AXE MEMORY Portable SSD 500GB Solid State USB Drive, USB 3.2 Gen2 UASP SuperSpeed+. Optimal Speeds Up to 600MB/s Read, 500MB/s Write - Speedy+

この手のUSBメモリにありがちだと思いますが、アクセスに伴って猛烈な熱を発します。 というか、連続でアクセスするとサーマルスロットリングが掛かって低速になり 最後にはデバイスを認識できなくなります。 パッシブ冷却では持続的なアクセスは困難だと思います。 一応、USBファンで空冷しながらであれば badblocks コマンドで250GB完走(1039秒)はできました。 USB3.0でJ4125という比較的低速なマシンでの確認ですが、コンスタントに240MB/secは出ているので キャッシュとかではなく、それなりに持続アクセスは可能です。冷却さえすれば。 冷却しない場合は……自分の個体はエラーになってしまいます。

スピードを計測するとRead:455MB/s、Write:452MB/sでSSDの性能はでています。 一見すると普通のUSBメモリにしか見えないのですが、かなり速いです。 特に書き込みではUSBメモリより圧倒的に有利です。 あとは価格がもう少し安くなってくれればと思います。

For sure this is one of the fastest USB drives Ive ever used. Its not quite to the stated speed of 600MBs read but it did write faster than the stated 500MBs speed at around 560MBs as you can see in the screenshot I attached to this review. You could actually edit 1080p video directly off this drive. In reality if you are using a lower bitrate 4k video you might be able to edit 4k right off the drive. I hope this becomes the standard for USB drives now. Its amazing how fast this one is!

I was honestly skeptical when I first saw this, but decided to go for it anyway. It definitely works as described and has a fairly fast transfer rate. This has become one of my favorite drives and I carry it with me frequently. I would definitely recommend this product to others!

This flash drive is fast when used with USB 3.2. It is detected as a fixed disk, instead of removable. I purchased this specifically for booting distributions from USB using YUMI exFAT from Pendrivelinux, and so far it has been working flawlessly for that. ;)

USBメモリ型のSSDです。 SSDながら、言うまでもなく非常にコンパクト&超軽量。発熱もほとんど感じられず、速度も爆速と言うこと無し。 あとは耐久性さえ問題が無ければ、モノとしては最高です。 250GBモデルですが、Windows11のシステムでは232GBと認識されました。 CrystalDiskMarkでは233GBとなっています。 参考値ですが、測定の結果、USB3.0ではReadが395.59MB/s、Writeが308.10MB/s。 USB3.1ではReadが412.64MB/s、Writeが322.18MB/sとなりました。 ※ただしGenは不明。 最大読出速度600MB/s、最大書込速度260MB/s(USB3.2 Gen2の場合)と謳われているので、それと比べるとReadは70%ほどでしたが、Writeはなんと120%超えという結果です。(Readも十分な数値だと認識) 価格面を見てみると、有名メーカー製のUSBメモリ型SSDの250GBモデルが4,500-8,000円程度で販売されており、5,000円前後というのは、あまり優位性が無いように思います。 ただ、性能面では同価格帯の製品を上回っているように見えるので、その点では優位性があります。 手持ちのバッファロー製と比べても非常にコンパクトなので、サイズの面でも極めて優秀。 まだ耐久性については分かりませんが、少なくとも今のところは、強くオススメできるアイテムです。

This thumb drive actually has a decent transfer speed for a USB 3.2. Most thumb drives have the right capacity but this one has faster speeds for a USB 3.2. Please be aware that you do need the correct port to utilize the full transfer speed. This is a great thumb drive to have for if you need a quick transfer of larger files or a back up for pictures and videos. Although 250 gb is a bit unorthodox compared to many other flash drives, pictures and videos probably could easily fill up 250 GB. I would say this is pretty nice to have some more important files stored safely on a thumb drive as back up if needed. The first thing I will say is that this thumb drive is a little thicker than your average thumb drive but it is still decent size for 250 gb. It is thin enough where it will not take up too much space. It does have a small loop I would say you could be a string through so you can put this on your keys or on a lanyard. This one is easier to put a string through because it is not one of those really small tight loops. In terms of scratching, this does not scratch as easy as say metal case thumb drives. The cap stays on pretty well however when you do not have any place to put the cap if you have the thumb drive open. You cannot put it on the back end like some thumb drives. I did do a test and verified that this thumb drive indeed has 250 gigabyte capacity and the transfer speed is pretty fast even on a USB 3.0. Again all varies as well on the port you plug into as well (if you are using 2.0 or 3.0. You have plenty of space to work with and transferring should not take too long, but you may be able to fill up 250 gb pretty quickly depending on the file sizes. For your average user, it will most likely take some time to fill up all the way unless you take a ton of pictures every day. Overall this is a nice thumb drive to have for storing pictures and videos but be aware with the sizes of videos and pictures you may actually fill this up pretty fast. Compared to other usb thumb drives, it has a super fast transfer speed. The only minor down side is that this thumb drive is a little thicker compared to many other thumb drives, but it makes up for it by have a decent transfer speed.

I’m using this for full-blown production purposes transferring CAD files to my MasterCAM machine and transferring Gcode files straight to 3D printers. The transfer speed has been amazing. Zero complaints!

I have the 250 GB model. This flash drive can be attached to a keychain, if the keychain will fit through the small hole. It has a For the end to keep the connector clean. The speed is nice, but not as fast as what it shows. But this can certainly have something to do with the computers that I use. I think that speed would be faster if there was a USB – C connector. But overall I am happy with this flash drive.
