bhvm posted a topic in Drives and StorageDear all, I am pleased to bring you, The Honest, Most detailed and Practical review of Seagate 1TB LAPTOP SSHD. The Prologue- One fine morning, I wake up to discover that my Primary Desktop computer was dead. All said and done, I had made my mind that this time, my primary computer will be a Laptop, and that did happen. Excitement aside, Moving to laptop also had a few let-downs, and the major one was HDD performance. My desktop PC had some very nice Black edition Drives in RAID 0. As a result, I was able to get SUBSTAINED File copy speeds of 250MB/s and Burst speeds of over 400MB/s. Moving to Laptop's Non-RAID , slow Storage made me feel very claustrophobic. The buy- I had an eye on Seagate's new Hybrid Disks since long. I have spent better part of my Sundays reading reviews and browsing the forums about this revolutionary product. However the earlier models were just 500GB (Seagate Momentus XT) and price was hard to digest. After a few months, Snapdeal offered me to buy the 1TB SSHD model for just a shade over 8k. I booked it immediately and the product was delivered within 3 days. Mind you, seagate did not send the retail package with retail BOX and manual, But an OEM product in Antistatic Bag , Brown cardboard and some bubble wrap. Perhaps the reason it was so cheap. Install- (windows 7 Ultimate 64) I was of thought that i'd restore my System image and be Happy within 20 Minutes. Wrong. After burning the Midnight oil and many failed installs, I figured out that Seagate SSHD is not friendly to Clone or Image installs. Take my word for it. You WILL need a fresh install for it to work, and Internet if full of such episodes. Performance- So here's what you people were waiting for. I Started copying my well over 800GB of DATA. I started in the Morning at 7.30 and the copy had suceeded by night 9pm. Quite longer than I had expected but system was rock stable. The copy was from SONY 1TB USB 3 HDD which gave speeds of around 45~65 MB/s. The Maximum Temperature I had seen was 46.c after a full days of Excersize. Perhaps the performance will open up after the Drive LEARNS usage patterns and caches them. And soon enough, its true after a couple of Restarts, the system boots to desktop in 22 sec. Regular programs like Opera Browser, Messenger, Open office, Desktop widgets, system monitor pop up in a blink. I am finally getting the pleasure of High end RAID array on a laptop. However, the substained speeds and long file transfers still remain a dream. Benchmarks- I have attatched ATTO disk mark screenshots for you. At first I was astonished to see bursts of 450MB/s. As result I ran the benchmark 3~5 times, but the results were consistent. I guess that the SSHD uses pretty high quality NAND cache with Read speeds over 400MB/s. A pat to Seagate on this one. Summary- What I liked- System Boots in 22.sec Regular Programs Pop out in no time Cool operation compared to previous Gen Momentus XT 7200 RPM Less power consumption and decent battery life. Very snappy system FEEL What I didn't like- Non cached Transfers fall back to usual 70~90 MB/s of traditional laptop HDD Spindle speeds of only 5400 RPM opposed to Previous Gen 7200 RPM. Quite Expensive in India compared to USA and Europe. OEM product available compared to Retail BOX as advertised by Seagate. Should you buy one? HELL YEAH!

Not sure if this belongs under Hardware or Software. The situation: Win 7 32-bit. 2TB Hard Drive. 900GB full, 960GB free (48% used). Wasn't very fragmented. Ran TuneUp Utilities 2010 Thorough Disk Defrag. Now only 127GB free. Windows Explorer and xplorer2 say so. TuneUp Disk Space Explorer says total filesize = 900GB, but also says only 127GB free. I have run chkdsk, checked for Restore Points, Shadow copies, Disk images, page file, hidden files... I can't figure out why the system thinks the space is used, but no files taking up that space. I have spent hours reading about similar issues, but still no fix. It may or may not be related, that this OS install has a bad corruption in device and USB Driver handling and possibly ntkrnlpa.exe. Also, when accessing an external drive, folders show up, but no files. Plugged into a different pc, and the files are there. I will have to re-install win7 soon, but I need to make partition images as a safety net. And to do that, I need my storage+backup drive. The reason I ran the checks and defrag originally is because Acronis failed to make backup image, stating 'bad sector'. Why is the disk reporting full, when it isn't; and how do I fix it? Thank you.
