My laptop (Asus Zenbook UX31) of 2 years old is now almost as slow as my old PC from 2008. I suspect it’s my SSD (SanDisk SSD U100 128GB).
Apparently Asus ships it’s laptops with different SSD’s and if you are unlucky you end up with a SanDisk. I went to Best Buy with it, but they will not replace it, because it’s still working but only very slow.
So how bad is it? I try to figure that one out, but it’s difficult to measure. Sometimes I get good results, sometimes bad. The only tools I have found for this is CrystalDiskInfo and CrystalDiskMark.
Here is the CrystalDiskInfo:
As you can see I’ve used a lot of Reads (17TB) and Writes (7,61TB), but the health is still good (88%). The scores for the attribute names are all 100.
And this is the CrystalDiskMark run:
Especially the writing can be very slow. Copying a lot of files can slow things down compared to one big file.
I’ve also used the SanDisk SSD Toolkit, but that gives the same info as the CrystalDiskInfo. I’ve read that you can reset the SSD, but then you loose all your data on the drive. Since I don’t have a copy of Windows, that’s not an option. The only options I have is to wait till the SSD dies or replace the SSD.
Today another slow day for my SSD, maybe it’s the weather:
For comparison I’ve added a normal hard drive (Hitachi HDS721050CLA362) which is a year older and has been running for 24417 hours (almost 3 years non stop).
The writing is a lot faster on this one.
This summer I finally decided to upgrade the SSD. First I bought a SSD (Samsung Electronics 840 EVO-Series), but that didn’t fit in my laptop. I found out you need a special mSATA connection for my Asus laptop, which isn’t universal.
I than asked Asus if the slow SSD falls under warranty. They said it would, but they didn’t give me any guaranties on replacing the SSD until they see it themselves. So you need to send the laptop to them for $50 and hope they replace it. I didn’t send the laptop, because they would probably say it still works.
So in the end I still have the same SSD. In the process I formatted and reinstalled Windows 7 professional and it looks the performance of the disk improved with it:
The slow SSD was an indication that the laptop was slowly falling apart, first the keyboard stopped working and than worse: the screen turned blank. In then end I had to buy a new laptop with a lot better Samsung SSD:
