## Questions & Answers

**Q: Is this really slc as advertised?  the price seems ridiculously low for a slc drive even if it's only 256gb.**
A: Features & details

Remarkable transfer speeds that enable faster bootup and improved overall system performance. (The advanced SLC Cache Technology allows performance boost and longer lifespan) 
7mm slim design suitable for Ultrabooks and Ultra-slim notebooks.

**Q: Is this SSD compatible with any desktop old and new?**
A: The guy that said this is a PCIe and NVMe drive is hallucinating. It's a standard 2.5" SATA drive, just like the listing says, and will work with nearly all desktop and laptop PCs (even Apple) that have a 2.5" or 3.5" SATA interface, which would be nearly all of them except for the very newest and slimmest laptops that no longer have a 2.5" bay.

**Q: Will this work for my for my asus q 302l**
A: Likely will work.  Just remember, most newer SSDs are 7mm thick.  If you are putting this in an older unit that had a 9mm thick drive then you will need the extra SSD spacer (usually foam or rubber material) to make up the difference to eliminate any possible motion with the extra empty space in the drive bay.  Have had many repairs come in for this very reason with the SSD connectors broken due to motion within the drive bay.

**Q: Can this ssd drive be used to replace a toshiba mk2555gsxf drive?**
A: Likely will work.  Just remember, most newer SSDs are 7mm thick.  If you are putting this in an older unit that had a 9mm thick drive then you will need the extra SSD spacer (usually foam or rubber material) to make up the difference to eliminate any possible motion with the extra empty space in the drive bay.  Have had many repairs come in for this very reason with the SSD connectors broken due to motion.

Very fast and cheap drive

### ⭐⭐⭐⭐⭐ works
*by B***S on 7 November 2018*

ssd 256Gb, works, super price

### ⭐⭐⭐⭐⭐ PUBG XB1
*by S***. on 15 January 2019*

Bought this to improve my load in and rendering times for PUBG on the OG XB1 and it has helped massively, buildings and weapons all rendered in when I hit the ground and based on friends that I play with it usually loads me into games around 40-60 seconds faster than everyone still using the internal HDD, sometimes I load in before the timer has started so around 70+ seconds before everyone else!! Looks great, performs great for what I need and my friends are all buying now for the cheap, easy upgrade
