Kingston UV400 SSD speed, Good Or Bad?

HritabanS_2661 · Nov 28, 2016

Hello!

This is my first ever thread in The Tom's Hardware Community! Can You please clarify if my SSD speed is good or bad? I know that it's a basic budget SSD and it's capacity is 128GB. But the Company Promises to deliver over 500 MBPS or 5 Gbps read/write speed. Note that now the capacity of the SSD is at 46% and its connected to a SATA 6 GBPS port. I have benchmarked it with crystal disk benchmark software(x64) and getting a read speed of 471.4 MBPS and a Write speed of 366.9 MBPS and the sequential read-write speed is 384.8 and 367.0 MBPS. Please clarify me if I am getting a good speed? If not, then how can I improve my SSD speed?

Thanks in advance!

Those are adequate speeds. You should make sure that your disk controller is set to AHCI mode so that the TRIM command can be sent to it. If you need to change the mode, you will have to tweak the OS first. Without TRIM, the SSD will slow down drastically once you have written 128 total GB to it, no matter how much free space there is.

What OS are you running?

I don't know how to switch to AHCI mode in The BIOS. I am running a fresh new Windows 10 professional (x64) and My motherboard is ASUS H110m- D.

Here's the manual: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/H110M-D/E11076_H110M-D_UM_WEB.pdf?_ga=1.17118654.687558237.1457212221 . The darn thing only tells you how to get into BIOS and the difference between the basic and advanced screens, so I can't give specific directions. Anyone out there either have this board or know where I can get UEFI details (it's not BIOS anymore)?

The steps are
1) Make a whole-disk backup of your system drive on an external disk. Test that it is valid. If we break anything in the following steps, you can restore this backup.
2) Registry tweak to tell the OS to use AHCI. See http://www.tenforums.com/tutorials/22631-ahci-enable-windows-8-windows-10-after-installation.html .
3) Shut down. Boot into the BIOS. Change the controller mode to AHCI.
4) Reboot.
5) Find some tool to double-check that the drive is indeed seen as AHCI and supporting TRIM. I use a utility that came with my Samsung SSD; does Kingston provide one?

I get it. Thanks. But in this link: http://www.windowscentral.com/how-ensure-trim-enabled-windows-10-speed-ssd-performance there is a thread about how to check if Trim is enabled ny default. I did as described over there, ran the command. And here's what windows tells me: NTFS DisableDeleteNotify = 0
ReFS DisableDeleteNotify is not currently set
So, what does that mean? Is Trim enabled By default or do I really need to go through all of that steps you provided?

If the controller is in IDE mode, TRIM is not enabled. The command is part of the newer command set and can't be sent over IDE mode. This is my guess for why you saw that. Although I've actually done this live IDE-to-AHCI trick, in Windows 7, we're getting past my experience here.
