Best Review: Seagate Barracuda 500 GB HDD SATA 6 Gb/s NCQ 16MB Cache 3.5-Inch Internal Bare Drive ST500DM002 - ok, so this drive is listed as the "Seagate ST2000DM001" and guess what, other than that it sports 2 Terabytes, it tells you nothing whatever about what drive you'll end up with, because Seagate has chosen to obscure and omit relevant Data between different builds, with vastly different performance.The short advice: Only purchase the WxExxxxx version of this model. This was made in Wuxi, China and uses 2 platters and 4 heads.This performs 30% better than the version with 3 platters, which has a WxFxxxxx or similar designation.You'll need to contact the seller and ask them to check the code on the drive. If they can't verify, don't buy it, better to get a drive from Western Digital, where its not a surprise game of whats in the box.S - SU - Suzhou ChinaW - WU - Wuxi ChinaZ - TK - Korat ThailandF = 3 platters with either 5 or 6 heads, while E = 2 platters.Weight info received in a comment here, suggests that the 'good' 2-platter drive weighs 534 grams, while the 'bad' 3-platter drive weighs 624 grams.Seagate used to embed the information about their drives in the model number, but now they obscured it, so they can pawn off whatever they want. Send a WxE model to Publications who test drives, and then ship the crappy WxF model to unsuspecting customers who may never realize they're not getting what they thought they were buying. This should really be illegal..Note 1: This was written for the 2TB drive. It turns out Amazon also shows this review for 3TB drives. This info does not apply to 3TB drives, the 3TB drives always have 3 1TB platters.Note 2: comparison test results here[...]Note 3: A relevant post on Seagate's forum stating that these Barracuda have been crippled through redesign [...]Note 4: Someone commented that Seagate removed any reference to the 2 platter version of this drive in the manual (something which is usually only read after the purchase)Note 5: Someone explained that Seagate made this change due to the flooding of their plant in Thailand. This is not quite correct since chinese 2 platter 2TB drives are also in circulation.Seagate's real reason for the change is being able to use lower bin or older tech platters that can only hold ~670 GB, so they use 3 platters. This is a fine business decision, but an honest company would give it a new Model number/name, as its a different product with lower speeds, lower reliability and higher weight.But why be honest, if you can cheat and make a few dollars extra per drive, by selling it under the same name as the better drive, which has been reviewed extensively and lauded for its higher speeds?
