Espeon 250GB Portable SSD Solid State USB Drive, USB 3.2 Gen2 UASP SuperSpeed+. Up to 600MB/s Read, 260MB/s Write - SS+

This is an extremely fast USB drive that packs in a very high amount of data. Read/write speeds are above expectation and with some posturing, this can be used as a secondary drive for a smaller device with USB-A ports. The limitation on this drive is your USB-A port, not the drive as I found out with my slower desktop 3.0 versus my faster laptop 3.1. With my usual load, I can easily get 220 MB/s write which is far better than what I get with other drives. The price is for the speed and package size, unlike the more commodity USB drives which are speed limited, this really does get the speeds around the premium one pays for this.

I used this Espeon SS+ 250 GB Portable USB Drive to transfer images and videos from my desktop PC to my laptop. The USB 3.2 speeds are fast, and this drive has been extremely reliable. Theres a loophole that can be used to attach this drive to a lanyard for safe keeping. I opted to keep mine secure within a pocket within my laptop case. I found myself wishing this Espeon SS+ 250 GB Portable USB Drive had a retractable USB A connector but the capped design may be better at keeping dust and debris at bay. 4.5 out of 5.0

PS5の拡張メモリとして使用。 見た目はただのUSBフラシュメモリですが 中身はちゃんとしたSSDで読み書きの速度がとても速いです。 見た目もコンパクトで存在を忘れてしまうようなデザインです。 特に処理落ち等もなく快適に使用できています。 本体ストレージとの速度差分は比較できていませんが体感では変わらない印象です。

Works great on USB ports. Does not bottleneck like most thumb drives. Good substitute for a drive in a case. Not as fast as fastest drives, but very good.

250GB品で読み込み公称値600MB/s、書き込み260MB/sならまあそんなもんだよねと思ってMacで実測したら、書き込み500MB/sも出てびっくりしました！(画像参照) 14インチMacBook Proで計測ツールはおなじみBlackmagic Disk Speed Testを使用。 現行MacBook ProにはUSB type-AポートはないのでUSB type-C/type-Aアダプタを挟んでの計測値です。 これで読み込みも書き込みも500MB/sオーバーなら500GB品と比べてもそんなに遜色ないんじゃ？ 見た目はUSBメモリですがtype-A接続のUSBメモリの場合は100MB/sいけばって感じなので、見た目USBメモリっぽくてもSSDの優位性は間違いなくあります。 また読み書き500MB/sオーバーってのは2.5インチSATAタイプSSDの実測限界値と同じくらいなので、あとは値段も2.5インチタイプと近いとこまでいってくれれば言うことなし！

6-24-2022 Update: I was surprised to find that even on my ancient 2012 MacBook Pro I got 200-300mbs. The only concern will be how long this drive lasts. The max speed of this flash drive requires USB 3.2 Gen 2. My laptop only supports USB 3.2 Gen 1, but the speed from this drive is impressive. It matches the speeds I get from some external M.2 SSD drives I use - around 400-800 mb/s read/write depending on the USB port I use. Write mode May be slower when doing large file copies, but burst mode is very nice. It has a lanyard hole, which is good, but the cap is not secured. I generally get fancier USB sticks that have a cover built in (via a sliding mechanism or a piece that just swivels around). I expect I will quickly lose this cap, though there is a place to snap it on the other end when it’s plugged in to something. I have been using it on a Windows 11 laptop. It is replacing an external SSD I had been using. New drives should always work great, but if it acts up six months down the line, I’ll update this review. NOTE ABOUT SPEED: You will see speed test screen shots. One shows high speed, and the other shows SLOW speed. Both were from the same laptop. Various USB hubs or even port extenders can cause speed degradation. For example, I have a laptop cooling fan that plus in to a USB port, then has a place to plug a USB device in to that. Connecting this drive to that adapter drops the speed. There are also flaky things with other ports — I have a USB-C device that goes through an adapter (USB-C to USB-A) and sometimes it’s blazingly fast, and other times it’s slow and I have to unplug-replug. I think sometimes hubs and adapters can get flaky and need to be reconnected. If you do not get high speed, try the device plugged straight in to your computer, and try different ports. I have never heard of this brand, so my only concern is longevity. Will my data last? Just make sure you always have a backup.

250GB Thumb drive, highly portable and an absolute ton of storage! Detected easily on my M1 Mac, easy to setup - storage transfer is really quite fast. Great way to backup to a physical/local storage device. Would be a great device for college students and working professionals alike. 5-stars!

Read600MB、Write500MBとなっていますが、Macでの実測平均は Read352MB、Write394MB 十分な速度出てますね〜。 デザインが個人的には好きで、懐かしのキャップ式でキャップは後ろに しっかりささります。 価格相応で十分満足出来ます。

This flash drive is the real deal when it comes to speed, I was using this to transport large video files for my brothers wedding. The write speeds actually surpassed the rated 260MB/s and actually got closer to about 330MB/s. This is no ordinary flash drive as the speeds are much greater than a lot of drives. For big files, this is a great price for this much storage.

This little USB memory stick is quite a surprise - its much faster than everything else I have laying around here (SanDisk, PNY, etc), yet it doesnt cost much (if any..) more. Attached test photo is from an older Mac computer with USB 3.0 ports. The cap (cover) of the USB connector is very firmly attached - it is definitely not going to fall off and get lost, and it can be securely stored on the back end when the device is in use. Thats a very nice touch - little things mean a lot.
