MacBookPro13Retina(2015まで)にも適合しますOSの都合で古いマシンを使い続けたいが、大容量ストレージが必要な方にはお勧めです

セカンドpcとして使っているMacBook air はストレージが少ないスペックですので、補助ストレージとして重宝してます。

MacBook Air 13inch (Mid 2014) で計測した QuickBench のベンチマークです。ほぼスペックどおりの速度が出ています。Transcend の Webサイト [・・・] からJetDriveToolbox をダウンロード出来る JetDriveToolbox を使うとスリープ状態に応じて自動アンマウント／マウントしてくれるのも便利ですね。QuickBench(TM) 4.0 Test Results(c)2000-2007 Intech Software Corp.Test Volume Name: JetDrive (Transcend JetDrive Lite 130 256GB)Test Volume Type: MacOS ExtendedTest Volume Size: 241.553 GigabytesTest Volume Free Space: 241.262 GigabytesAllow Disk Cache Effects: DisabledAll reads and writes performed sychronouslyStandard Test Results:Test Cycles: 5Transfer Size Sequential Read Sequential Write Random Read Random Write4 KBytes 5.323 MB/Sec 25.976 MB/Sec 5.301 MB/Sec 0.929 MB/Sec8 KBytes 10.080 MB/Sec 46.549 MB/Sec 10.193 MB/Sec 1.714 MB/Sec16 KBytes 16.247 MB/Sec 42.704 MB/Sec 14.135 MB/Sec 3.003 MB/Sec32 KBytes 25.137 MB/Sec 49.872 MB/Sec 24.304 MB/Sec 5.470 MB/Sec64 KBytes 63.864 MB/Sec 53.815 MB/Sec 37.250 MB/Sec 7.951 MB/Sec128 KBytes 77.074 MB/Sec 63.635 MB/Sec 54.231 MB/Sec 12.165 MB/Sec256 KBytes 83.921 MB/Sec 58.766 MB/Sec 68.097 MB/Sec 19.686 MB/Sec512 KBytes 87.685 MB/Sec 66.080 MB/Sec 78.123 MB/Sec 27.849 MB/Sec1024 KBytes 89.287 MB/Sec 61.961 MB/Sec 83.951 MB/Sec 35.518 MB/SecStandard Ave 50.958 MB/Sec 52.151 MB/Sec 41.732 MB/Sec 12.698 MB/SecLarge Test Results:Test Cycles: 5Transfer Size Large Read Large Write2 MBytes 90.494 MB/Sec 68.031 MB/Sec3 MBytes 90.803 MB/Sec 67.800 MB/Sec4 MBytes 90.766 MB/Sec 67.512 MB/Sec5 MBytes 90.151 MB/Sec 56.276 MB/Sec6 MBytes 90.680 MB/Sec 68.833 MB/Sec7 MBytes 90.786 MB/Sec 68.416 MB/Sec8 MBytes 90.945 MB/Sec 68.246 MB/Sec9 MBytes 90.225 MB/Sec 58.446 MB/Sec10 MBytes 90.583 MB/Sec 67.995 MB/SecLarge Ave 90.604 MB/Sec 65.728 MB/SecExtended Test Results:Test Cycles: 5Transfer Size Extended Read Extended Write20 MBytes 91.038 MB/Sec 64.049 MB/Sec30 MBytes 91.051 MB/Sec 65.005 MB/Sec40 MBytes 90.939 MB/Sec 50.259 MB/Sec50 MBytes 91.024 MB/Sec 55.402 MB/Sec60 MBytes 91.142 MB/Sec 65.111 MB/Sec70 MBytes 91.132 MB/Sec 65.414 MB/Sec80 MBytes 91.101 MB/Sec 64.656 MB/Sec90 MBytes 91.128 MB/Sec 65.125 MB/Sec100 MBytes 91.033 MB/Sec 63.117 MB/SecExtended Ave 91.065 MB/Sec 62.015 MB/SecCustom Test Results:Transfer Size: 500 MegabytesTransfer Count: 4Test Cycles: 2Contiguous File Only: NoMaximum Measured Read Speed: 91.152 MB/SecAverage Measured Read Speed: 90.941 MB/SecMinimum Measured Read Speed: 90.047 MB/SecMaximum Measured Write Speed: 64.750 MB/SecAverage Measured Write Speed: 59.774 MB/SecMinimum Measured Write Speed: 52.704 MB/Sec

MacBook で出っ張らなくて、容量UPできて良い

SDカードスロットのあるMacBookProに拡張ストレージとして使用。スピードは速くないが内臓SSDの他に1TBストレージが持てる安心感は大きい。出し入れにはコツが入りますね。挿しっぱなしで使えば良いのでノープロブレム。2TBが出れば欲しい。

SDカードスロットにぴったり収まります。書き込み速度はそこまで速くない印象を受けていますが、Time Machineのバックアップには十分使えます。挿しっぱなしにしておけるので、絶対にバックアップを忘れません。良い買い物をしました。l

It is a good way to increase storage capacity for large media files. It is noticeably slower than the native SSD obviously so only want to use it for files you won't access very often or edit. The drive fits snugly in the SD slot. The jetdrive software usually allows for the drive to be unmounted and remounted when the computer is put to sleep. Sometimes that fails however and the drive needs to be physically pulled out with fingernails and reinserted to be read. Have used for about a year and has been very useful.Overall a nice way to free up more space on your SSD.

SDカードは役に立たないものも多いが、これはとても信頼できるように思える。
