SanDisk SDSDQUA-016G-A11A Flash Card
  • Verified Owner
  • Owned For: less than 1 day

1 out of 5 eggs DOA 05/30/2012

This review is from: SanDisk SDSDQUA-016G-A11A Flash Card

Pros: Looks pretty.

Cons: No files could be written to the card. Only a quick format was successful, full (long) format failed regardless of chosen filesystem. H2testw failed on byte 1.

Error writing file 'N:\1.h2w', offset 0x0.
It is still possible to verify the test data written up to this point.
(The request could not be performed because of an I/O device error. Code 1117)
Writing speed: 0.00 KByte/s
H2testw v1.4

SAMSUNG EcoGreen F4 ST2000DL004 2TB 32MB Cache SATA 3.0Gb/s 3.5
  • Verified Owner
  • Owned For: 1 month to 1 year

Pros: Low power, and low price per gigabyte.

Cons: The drives silently return corrupt data. Luckily, I am using two drives in a mirror and my file-system is catching the bad data. I am using ZFS, which stores checksums with all data to later verify it when it is read back. During weekly scrubs of the mirror, I find 70-140 mis-matched blocks where the checksum don't match! This is data that the drive returned as valid (no hard read error), but is actually invalid. I have tried different SATA host controllers and the drives still return bad data. Disabling NCQ had no effect.

The latest Windows filesystem (NTFS) cannot detect bad blocks until it is too late. If it weren't for ZFS's end-to-end check-summing and mirror verification, there would be no indication that the blocks are invalid until a file using those blocks is read. As always, protect your data with a hardened file server and good backups.

Other Thoughts: I use smartmontools, and have applied the firmware patch to correct lost data from reading smart parameters during an NCQ write. This firmware patch did not improve the drive's issues and it still returns corrupt data. I have another mirror with Hitachi drives in the same configuration and it has been flawless with zero read errors in 2 years! I will not be buying any more Samsung drives! If you value your data at all, I would recommend that you avoid them as well.

1 out of 5 eggs Error Prone - Don't use for important data 06/15/2011

This review is from: SAMSUNG EcoGreen F4 ST2000DL004 2TB 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive Bare Drive

Pros: Low Power. Low price per gigabyte.

Cons: High Bit Error Rate. My file system (ZFS) uses end-to-end check-summing to protect data on drives like this one. I average 70-140 bad blocks of data during weekly scrubs. But, the drive doesn't report the data as a hard read error. The drive happily passes on the corrupt data as if it were valid data! All of the errors, luckily, are caught by the file-system, and repaired from the other disk in the mirror.

Other Thoughts: I am using smartmontools, so I have applied the firmware update for reading smart data while performing NCQ writes. There was no improvement in data retention. I have completely disabled NCQ and the drive is still feeding me corrupt data. I have even changed SATA host controllers and not seen any improvement in the error rate. My other mirror is an identical setup with Hitachi drives and works flawlessly. I would steer clear of these drives if you are not in a RAID and value your data. I know that I will not be buying Samsung drives any time soon...
