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

従来のUSBメモリ感覚で使用できるSSDメモリ。 高速で書き込み、読み込みができ大容量データの持ち運びに重宝しています。 ただ、過熱しやすく寿命が案外早いかもと思うこともあります。 値段に対して高級感が無い外観なのが残念なポイントですが満足度高いです。

大容量で、それなりに高価なUSBメモリですが、本体は樹脂製で、高級感はありません。 手持ちの数百円のＵＳＢメモリとも大差ない見た目で、所有する喜びはそれほど感じませんでした。 本体裏面にはUSB 3.1 Gen2のロゴ、リサイクルを求めるマーク、CEマークが大きく印刷されています。 アクセスランプは赤色LEDです。 高級感はないものの、造りはしっかりとしておりUSB部分のがたつきはなく、プラグ部も頑丈な造りです。 キャップは後ろ側に取り付けられるため、紛失しにくく、本体にひもを通すことも可能です。 他人とのデータのやり取りなどで受け渡しの際、紛失予防にもなりそうです。 UASPに対応しており、 USB 3.2 Gen 2 端子搭載であれば高速な読み書きができます。 メインのPCではUSB 3.2 Gen 2端子があるのですが、サブのノートパソコンではUSB3.0の端子だったため、そちらではどのくらい速度が出るのか計測してみました。 読み込み、書き込みともに450MB/s程度の成績で、USB 3.2 Gen 2 には及ばないものの高速な読み書きが可能でした。 今まで外付けHDDを使っていたような作業がこちらのUSBドライブで手軽にできるようになり、持ち歩きの際も衝撃などを気にする必要がなく、気軽に使えるようになりました。 手持ちのデバイスのUSB 3.2 Gen 2対応の有無にかかわらず、こちらを選択する価値はあると思います。

The manufacturer claims 260 MB/s writes and 600 MB/s read speeds I was only able to get 345 MB/s reads and 280 MB/s write. I saw other reviewers post read speeds of 455 MB/s so I believe the claim of 600MB/s maybe a little bit on the far side but this drive is still blazing fast. The write speed was higher than the claimed 260 MB/s but the reads were slower than the 600 MB/s claim by a large margin. I tested my read speeds from my M.2 drive which I was using on the test and I was getting 2100MB/s reads and 2000MB/s writes on my Western Digital Black NVMe drive. I tested my SanDisk portable NVMe SSD and connected on the same USB 3.2 port was able to get 720 MB/s read and 755 MB/s writes so my system is capable of pushing the limits of the portable USB drive. The drive was recognized as a USB 3.2 device on my Dell desktop 5090 specs: i7-11700T, 32 GB DDR4 3200MHz memory, M.2 NVMe WD Black drive, Windows 10 Pro When copying to/from a NVMe drive connected via a external USB drive enclosure I am able to get over 900MB/s reads and 600 MB/s writes to a Samsung M.2 NVMe V1.3 drive on my USB 3.2 port so the bottleneck is with the portable SSD drive. One thing I noticed when copying large amounts of data to the drive the write speed begins to drop as the drive heats up. I started the test and the drive temperature was 48C and after copying over 100GB the temperature had risen to 70C and while copying the drive speed decreased from around 285 MB/s to 135 MB/s I suspect due to the heat the drive started to throttle the write for thermal protection. The price to storage capacity and the speed makes this a great value because for $45 dollars you get a 256GB thumb drive with blazing speeds in a very compact size. I have several other 256GB thumb drives and they average around 45 MB/s to 55 MB/s nothing close to the 350 MB/s this drive delivers in real world usage.

Ive got quite a few flash drives, and while I recognize it is marketed/billed as a 500Gb SSD drive, it visually looks like a flash drive to me. The largest flash drive Ive had prior to now is 128Gb, so 500 is large increase. I dont normally need to carry around that many files, but there are a few times where it would helped in the past to have it around. Several other reviews talk about read/write times. Thats less of a concern to me, as most of what I use these kind of drives for is not that intensive, so the lesser speeds work for me. But it is rated higher than I believe the ports on my computer are for, so if you are in need of some faster stuff, this will probably work for you. I do agree with one of the other reviewers and say the plastic shell doesnt feel like the most durable. But it doesnt feel loose connected to my computer, and the USB-A port on the end is not wobbly (as Ive seen with some portable drives). If youre in need of this kind of space in a portable form, this would work well for you.

I have included an image of my read/write speeds, which are great for a drive in this price range. The size makes the drive much more versatile, making it perfect for moving around large files for video editing or secure local backups. It does get warm when writing large files, which likely would cause thermal throttling of the speed if moving a lot of data at once. For the price, I think it is a great purchase. If it fails prematurely, I will update this review.

Use this for my photography trips where I back up my photos on my laptop and then onto this while Im out for temporary redundant storage on the chance something happens to my laptop. The USB does perfect and havent found any issues while making transfers and while doing larger transfers >10 gigabytes, havent seen a noticeable dip in write performance. Love it and keep it at the end of my keychain.
