Pros: *Ultra thin form factor (7mm) *Faster than your average hard drive *Outperforms SSD's in large quantity small file transfers I decided to do a real world performance test between 3 different hard drives in order to gain a speed perspective. I put this slim drive up again a Force GT 120GB SSD & 1 TB 7200 RPM Constellation Enterprise HDD. The test consists of 3 different types of files: Large Bulk Compressed Software Image, 3 Movie Files, and a Folder with 1000+ Pictures/Files of various sizes. Results are below 1000+ Pics/Files (2.84 gb): Seagate Thin - 430 mb/s 1 TB Constellation = 84 mb/s Force GT SSD - 96 mb/s Large Compressed File (10 GB): Seagate Thin - 128mb/s 1 TB Constellation = 150 mb/s Force GT SSD - 130 mb/s 3 Movie Files (3 GB ea.): Seagate Thin - 120 mb/s 1 TB Constellation = 125 mb/s Force GT SSD - 140 mb/s I can't explain why the thin drive does so well on large numbers of small files but it was almost instantaneous and 100% reproducible every time with no info loss. Cons: *Capacity restraint (splitting hairs here) *Fragile feeling construction Overall Review: It's a top tier hard drive just as everyone else is saying. I would definitely recommend this drive to anyone who does not have access to a SSD. I do wish the warranty was longer though as the construction does seem a bit fragile due to the thinness.
Pros: Pretty fast. Very thin. Does what it suppose to do. Cons: Very thin. Yes I know I put very thin as a pro. But this can be a con for some applications without some type of modification. Perhaps a little pricey. Also I think 2 year warranty is a little short. 3 years would be better. Overall Review: I did several tests with this drive and compared it to some 3.5" drives. To my surprise this drive performed as well or better. Than a Seagate 2TB drive and a WD 750GB black drive. In seq read/write. In random read/write this drive was not as fast as 3.5" drives. I would recommend this drive to anyone looking for a 2.5" HDD. Of course a SSD would blow this drive out of the water. But that's like apples to oranges. Newegg/Seagate should not list the "SECURE SELF-ENCRYPTING DRIVE OPTIONS" under features of this drive because this drive does not have this feature.
Pros: This is only an amended review to a previous. The same pros still apply. Here are updated benchmarks: Speeds with 512 byte allocation CrystalDiskMark x64 in Windows 8: Sequential: 149 MB/s read and 135 MB/s write 512K: 67 MB/s read and 48 MB/s write 4K: 1.08 MB/s read and 0.4 MB/s write Speeds when reformatted back to Advanced Format/4K allocation CrystalDiskMark x64 Windows 8 (0% filled.): Sequential: 142 MB/s read and 137 MB/s write 512K: 49 MB/s read and 29 MB/s write 4K: 0.60 MB/s read and 0.31 MB/s write Speeds before, at 4K and 88% filled with data: CrystalDiskMark x64 Windows 8: Sequential: 90 MB/s read and 68 MB/s write 512K: 47 read and 36 MB/s write 4K: 0.76 read and 0.27 MB/s write Cons: 1. I'm keeping one egg off for the misleading advertisement. The obfuscated print says "Self-Encrypting Drives (SED) and FIPS 140-2 Validated drives are not available in all models or countries." Keep in mind that though they are advertising these drives all around the internet as having the encryption feature *****only one of the five drives in this lineup has the encryption feature and that is the 5400RPM/500GB/16MB cache model, no 7200RPM models.***** If I pull up a listing solely for purchasing a 7200RPM/500GB/32MB cache drive then it will advertise self-encryption. Only clicking through data sheets and PDF files will a buyer realize this is misleading. 2. Also, when this drive fills up it seems to slow down. I have 11TB of [Mostly Seagate] storage in my desktop and some drives are filled. I tested them and the read/write speeds are on par with how they’ve always been. With this drive, however, when it was up to 88% filled the speeds were nearly halved. Just an observation to note. Overall Review: This is still a solid drive so long as you are not purchasing it for the encryption technology or, as it appears, planning to use it for anything demanding speed when the drive is filled. I also would call into question it's performance if someone were to encrypt the entire disk. If performance suffers with the drive filled, then preallocated disk encryption would likely cause it to suffer in performance as well but I have not tested this scenario yet, personally.
