Question Why is Toshiba SSD write speed so bad?

[farmhanddane]

It just a few months old in a new machine, I noticed installing virtual machines was pretty slow so I tested it compared to the HDD, see picture: http://oi68.tinypic.com/6ith0i.jpg

Which Toshiba SSD is that and where is it installed ?

It's called BG3 (KBG30ZMS128G) and according to the specifications it's supposed to write 470MB/s.

Not sure about where? SCSI Port 0?

Where = In which computer ?

Dell Inspiron G3

I'm sure that is supposed to read as "Up to 470MB/s" which most manufacturers do since they cannot guarantee max speed thru every hardware configuration. Plus that would be only for sequential file transfers.

I get a blank screen with that link but can see other pics on Tinypic ... what speeds are you getting?

I also changed the link in the original post.

That can be any number of things. Bloated OS (I mean it's a Dell) and Windows Updates are common culprits. Check your task manager to see what the OS is doing when idle.

Then, every SSD has some wear leveling techniques which are ought to slow it down. If you've been using it heavily for those few months, with virtual machines and whatnot, and not giving it much chance to balance the wear, it may get slow.

How full is the drive? If it approaches full, then it's gonna get slower too.

Is it possible to wipe the drive and test it when it's blank? If not, can you at least leave the PC running for a night or a full day without working on it?

What should I check for when it's idle?

120 GB is quite small, but I try to keep most things on the HDD and I run the Windows 10 compressed. I actually run some of the virtual machines on the HDD, the two I use on a daily basis do run on the SSD, but mostly not all day long I reckon.

I have 30 GB free space right now, I had about 10 GB free before removing temp files and some things.

I'm unable to test it when it's blank. I will try running it a full day/night, what will this accomplish?
