Yeah, thanks.

好的，謝謝。

I didn't actually mean to drop it that hard.

我其實沒想摔得那麼重。

When I was a kid,

我小時候，

SSDs barely even existed.

固態硬碟幾乎還不存在。

I mean,

我的意思是，

CompactFlash barely existed.

Then in college,

後來上大學時，

they were prohibitively expensive. 片語搭配

它們又貴得離譜。

And then for years,

在之後的那幾年裡，

the play was to have a one-two punch, 講解

a small capacity SSD for speed and,

用一個小容量SSD來提速，然後，

you know,

It works by looking at the transfer of a large set of files 文法

它的原理是在執行指令前檢查一大批檔案的傳輸，

and optimizing the order in which they're read or written to before executing the command. 文法

最佳化讀寫的順序。

This is better,

這當然更好，

but it's still a physical limitation that SSDs simply don't have.

If you want to start multiple file transfers from a hard drive,

如果你想在傳統硬碟上開始多個檔案傳輸，

you'll be limited by how quickly the read head can move back and forth

你會受到磁頭在所有檔案間

between all the files.

With an SSD,

而對於SSD，

response times are mostly limited by software,

反應時間主要受限於軟體、

你的CPU，

or the interconnect to the host.

And fair enough,

這也無可厚非，

because as it turns out, 片語搭配

once the loading is done,

一旦載入完成，

hard drives are fast enough to feed games like GTA V or even Cyberpunk 2077 with the necessary data as you zip through the streets at 1080p.

傳統硬碟的速度足以在你1080p畫質下穿梭街頭時，為像《GTA 5》甚至《電馭叛客2077》這樣的遊戲提供必要的資料。

However,

with the new consoles coming with support for technologies like DirectStorage 文化背景

隨著新主機開始支援像DirectStorage這樣的技術

that allow the GPU to directly access a drive that ideally would be NVME,

hard drives may not only cause stuttering and hitching, 文法

傳統硬碟可能不僅會導致卡頓和延遲，

but could limit the visual quality in your games as well.

還會限制遊戲的畫質。

To say nothing of falling through the unloaded floor. 表達脈絡

但這不僅僅關乎速度。

Not only are SSDs quieter because there are no moving parts, 文法

SSD不僅因為沒有活動部件而更安靜，

they consume significantly less power as well.

you're looking at a potential noise increase 用詞

你將面臨潛在的噪音增加，

雖然這差距不是特別大，

if you're the kind of person

但如果你是那種

who likes to get the lowest wattage power supply possible for your build,
