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

データのバックアップ用に使用しています 結論からいうと とても満足ができる商品です 良いところ →早い転送速度 転送に時間がかからないのでストレスが少ないです →軽量コンパクト 小さい上に軽いので持ち運びがし易いです →安定した接続 以前使用していたSSDは転送中に接続が切れるということがあったのですが この商品はとても安定して 接続が切れないです 以上の点からオススメできる商品です

SSD＋ケースで買うよりも、ケース分安く付くので 最初から外付け目的ならば安くつきます。 今のところ映像データの保存でも、USBメモリに比べて早くなっている。 今後の読み書きを繰り返した後も、高速処理に期待したい。

今までの激安大容量USBメモリと違いSSDだとこうも違うのか。全然速い。 type-CのUSB3.2で接続したUSBメモリと比較しても引っかかりが無い。すごい。 これで1年は元を取りたい。

This is a great solution for me, since Im using multiple computers for crypto farming. I can move files around over my network, or use on line storage, but this little guy is faster and doesnt eat up bandwidth moving chia plots around as needed to optimize drive space. My computers immediately recognized it and I was able to use it immediately without any software or special config - truly plug and play. Great price, great device.

This USB is great. I have been using this foor uploading huge lists of music. I tend to be able to upload 3GB in under 20 seconds.

Saw the good reviews and thought Id try it myself. I have a brand new 2022 Asus Zenbook 14 OLED with a fast internal M.2 PCIe SSD and a USB-A port supporting high-speed USB 3.2 Gen1 I/O running Windows 11 Pro. This Espeon SS+ 500GB Portable SSD Solid State USB Drive comes preformatted using exFat. Heres the issue: Small files copied from my internal HDD to the USB drive do achieve 480 Mbps write speeds. However, large (32Gb) file writes over wifi fail with the error seen in the attd pic. To test a large-file write to the flash drive, I had to copy the same file to my laptops internal HDD first, then to the flash drive. That process errored out the first few times with Windows asking me to scan and repair the drive. It also acted like it disconnected and reconnected when that happened (I didnt change a thing) because a new File Explorer window popped open indicating that Windows 11 believed that I had just inserted the flash drive into my USB port. you can see from my second pic that the write speeds dropped over the course of the file transfer. I noticed the USB storage device felt warm to the touch, so for all I know it was thermally throttling itself and purposefully decreasing the transfer rate. hard to tell without repeating this test in a freezer, which I am not about to do. After all, we have to be realistic and run real-world test scenarios. So, while I love the idea of finally having a portable USB storage device that can achieve incredible speeds, something about this product, plus my laptop, plus Windows 11 is just off. Ill update this review if it turns out that in 6-months everything learns how to play nicer but for now Im rating this 3/5 stars.

The USB stick comes in a basic display card and is easily cut open with scissors. The white shell of the drive feels like a very cheap plastic, which does not lend a premium feel to this USB drive. It has a cap that pops off with just the right amount of force, neither difficult to pull off nor am I worried itll accidentally come off. The USB interface is securely mounted, as theres no wiggle between it and the plastic housing (something Ive seen on cheaper USB sticks). After plugging it into my computer, I was pleasantly surprised to find my system reported that this 250GB drive actually has the advertised capacity (250.06GB), as usually manufacturers overstate the available capacity. I gave it a fresh format in exFAT so itll work in both my Mac and my PC, and ran it through Blackmagics Disk Speed Test Tool, selecting the 5GB option. Now this drive really surprised me, as its advertised at 260 MB/s write speed and up to 600 MB/s read. The Blackmagic test, however, showed it far exceeding the advertised write speed, hitting 583.5 MB/s. More than double the speed! Write speed was more in line with the advertised speeds, hitting 542.1 MB/s. Now, most drives can handle smaller transfers like that quickly, but the real test is if they bottleneck on larger transfers, as the faster cache gets filled and the actual flash memory speed becomes the limiting factor. Also, the number of files can affect transfer speeds, as many small files will take longer than one large file (of the same total size) due to inefficiencies. To test this, I made several transfers to/from the drive of various sizes and file counts. I made sure to give the drive a break between each test so heat buildup wouldnt affect the times. I was timing off my stopwatch, so the times arent extremely precise due to possible variance in my reaction time, but should be pretty close and accurate enough to get the overall picture. If you look at my chart, youll see that both read and write speeds are best under 20GB. I observed that after about 12-13GB, speeds dropped off, likely as the cache got saturated and the drive was forced to slow down and write directly to the flash memory. To test this a little further, I made notes of how many seconds it took to hit 10GB increments with the 45.94GB transfer, and heres the times it hit each marker: 10GB - write 18s, read 20s 20GB - write 50s (+32s), read 50s (+30s) 30GB - write 1m 37s (+47s), read 1m 20s (+30s) 40GB - write 2m 56s (+79s), read 1m 51s (+31s) As you can see, the write speed suffers the most as the transfer gets larger, but the read speed settles in to about 30 seconds per 10GB. I didnt run this test on all the folders, but noticed similar behavior over the course of the larger transfers. For a control subject and to make sure my Macbook SSD drive wasnt a bottleneck (it shouldnt be, as they are way faster than this USB should be), I ran the same file transfers to my Sandisk Extreme SSD (gen 2). As you can see from the chart, it was faster in all scenarios, and significantly faster in a good number of them. This also brings up an important point: at the current $45 price point for the 250GB Espeon, youre paying $0.18 per GB. With the much faster 1TB Sandisk Extreme SSD clocking in at $130, youre only paying $0.13 per GB, a much better value. That said, if you dont want to lay out so much money and want the more portable USB stick form factor, the Epseon USB stick does a pretty admirable job and when writing under 20GB, far exceeds its advertised write speeds, though read speeds fell a little short under all my tests. Overall, Im pretty pleased with the performance of this drive. While it gets fairly warm to the touch under load, I never felt like it was excessively hot. The plastic housing leaves a little to be desired, but Ill take a cheaper shell with good internals over a slow USB drive any day. There are better values if all you care about is speed and drive capacity, but for a USB stick, this one isnt too bad.

実容量は 466GBの SSDを利用したUSBメモリです。 SSDですので速度は速く 計測したところ概ね満足のいく数値でした。 公称値よりは少しだけ劣るかも知れません。 (利用環境に依ります) コンパクトですがキャップを外すタイプなので キャップを失くさないかだけ心配。

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。

This is not the review you want if you want all the technical details about transfer speeds, etc. I got it because I needed to offload a bunch of pictures and files from a Cloud Drive. With a synchronous Gig internet connection I was able to seamlessly transfer 385GB of files with no issues. That is all that was important to me.
