Pros: Lots of storage space.
Much cheaper than equivalent Western Digital drives.
Cons: These drives are not reliable at all.
Early warning sign:
- Of all the drives I own (all but these are of other brands), the Seagates were the only ones which showed a non-zero amount on the Seek Error Rate shown by CrystalDiskInfo.
- Granted, because this is a third party tool this may or may not mean anything. So I didn't rush to RMA them soon after purchase. But perhaps it was a warning of what was to come.
- Just under a year ago, when copying files to or from these disks it would take three or more times as long as it did when copying those same files between non Seagate drives with similar specifications (3TB, 7200 RPM, 64 MB cache, RAID 1, same Motherboard).
- Event log showed a bunch of timeouts being reported out of the port to which one of these drives was connected. My initial thought was fragmentation, so I proceeded with a defrag which took about a day to complete (because of the timeouts). This seemed to fix the problem for a while.
- Not long after, the timeouts came back. So I decided to leave static data on them.
- Late last week I decided to pull one of the drives and run tests on it, including SeaTools from Seagate. For starters CrystalDiskInfo showed a caution warning related to Uncorrectable sector count. So I tried Seagate tools and it couldn't complete the tests. I tried chkdsk and that too failed.
- After backing up the data to a different Raid 1 array, I pulled the second drive and it had the same issues.
- Furthermore, three of the files I had on this disk were unrecoverable. As soon as the OS tried to read them the OS would disconnect the hard drive. I'm thinking those files were sitting on the bad sectors. Not a huge loss since I was able to recover the files from offline storage.
Other Thoughts: This is an update to a prior review I had done of this product (February of 2014). My original review was two months after purchase. Both drives were working fine and were fast. Over a year has passed and these drives are on the verge of complete failure, so I've taken them out of service and I'm sending them back to Seagate.
These drives are cheaper for a reason. Stay away from them.
Pros: Still one of the fastest 128GB SSDs on the market today.
Sequential read speeds top out at about 530 to 540 MB/s.
Sequential write speeds top out at 370 to 380 MB/s.
Smaller 128 GB SSDs have less channels in use as opposed to their 256 GB and 512 GB counter parts. Thus their write speeds top out at lower speeds.
5 year warranty.
These Samsung SSDs are unaffected by whether the data is compressible or not.
This SSD is installed on a laptop and it is the only storage device. Even so it is wearing at a more than acceptable rate. Thus far it has written about 1TB and the wear indicator is at 14 (maximum number of writes to the NAND blocks). Per those numbers, I estimate the SSD should be good for about 214,285 GB before it reaches the 3000 maximum P/E cycles (give or take a few GB).
Other Thoughts: I bought the Samsung 840 Pro SSD for my wife's Sony Vaio laptop. Installation was as easy as taking the HDD cover off the laptop, pulling the mechanical SSD out and installing the 840 Pro in. That's it (well, had to install the OS afterwards of course).
The laptop was already fast (i7 Sandybridge and 8GB of RAM), but this SSD takes it to an entirely new level. Consider that many laptops come equipped with slower 5400 RPM drives.
Yes, 128 GB is not much by today's standards. However, we have a home file and media server were we keep all of our files, so the laptop's SSD only has to have enough space for OS, Programs and caching.
After almost a year of envying this SSD's speed, I bought two Samsungs 840 Pro 256 GB and installed them on my work and gaming rig. I'm getting over 1 GB/s read and write speeds! (core i7-4770K on Gigabyte Z87X-UD5H mobo).
This review is from: APEVIA CVTUSBE25 11" USB Extension Cable for a standard USB motherboard connector
Pros: Does what it is supposed to do.
I have an internal USB card reader mounted on a Xigmatek Elysium super tower. The USB cable on the reader is not long enough to reach the motherboard's header.
The extension provides the needed extra length to reach it.
Cons: None.READ FULL REVIEW
